The Importance of Soap Fillers

Fillers are important substances which we can add to different products such as soaps, cosmetics, liquid laundry detergents, or others. The goal is simple – to change and improve specific properties. Soap fillers can add great value to our products. However, you will not discover any of them here unless they are an essential ingredient. Depending on the type of products, the soap filler can range anywhere between 5-20% for soaps and up to almost 50% for detergents.

Some notable examples of soap fillers

Kaolin. You might know it by its other name China Clay. It doesn’t dissolve in water but can easily disperse in it. Kaolin can be a vital component of some solid soap bars as it has a whitening effect.

Sodium Silicate. It can add transparency to specific products. As an anti-oxidant agent, sodium silicate can increase the duration and harness of the soap bars. Sodium silicate can also prevent corrosion from appearing.

Talc. Like Kaolin, Talc does not affect chemical reactions nor does it dissolve in water. These qualities are useful for some specific soaps or detergents because the soap filler will add value without having negative changes to the end product.

Sodium Sulfate and Chloride can also be great additions to soaps as drying agents. Extracts from green tea can help with skin care, by repairing the dying cells and slowing aging.

Additives can also be useful

They can improve the end-product by adding skin conditioning property. A good example here would be Glycerin. Sulfur can prevent acne from appearing. Titanium Dioxide can be of use for extra whitening power. It reduces the transparency

The benefits

There are a number of good reasons to use a soap filler for your products:

  • They prevent powders from clumping
  • There is a thickening effect for water
  • An increase in foaming capacity
  • Preventing the soaps from slowly drying out
  • There is also a strong cleansing effect
  • Some soap fillers are good for the health because they can protect the skin from drying or damaging effects
  • Improving the duration and endurance of many soaps or detergents
  • Overall improvement in the cleaning capacities of the product


With or without a soap filler, our products maintain their amazing quality nonetheless. We value our customers’ needs by constantly striving to provide the best work we can. Feel free to contact us if you want to learn more about our custom soap manufacturing business.

Everything You Need to Know About Soap Fillers

Soap filler is a substance that is usually infused in a body soap or detergent in order to tweak its physical attribute so as to make it effective for a specific application. For instance, sodium dodecyl sulfate and ammonium lauryl are two of the most widely used foaming agents in detergents and laundry soaps that help in better rinsing of clothes. Then again, adding borax as soap filler fortifies the product’s free-flowing property and imparts hardness.

So, you see, adding fillers during the process of soap manufacturing serve a particular purpose. The weight of the filler in the soap could vary from 5%-20%, depending upon the manufacturer as well as the chief purpose for which the product will be used. Let’s take a look at some of the most commonly used fillers in the soap manufacturing industry:

  1. Sodium Silicate

Sodium silicate also referred to as ‘water glass’ and ‘soluble glass’ is the term used for a group of compounds that have a varied range of manufacturing, agricultural, and industrial uses. This compound is extensively used as soap filler, particularly in bars of laundry soaps for enhancing their shelf life. This filler has anti-oxidant properties that checks soap corrosion.

  1. Kaolin

Also known as China Clay, Kaolin is a soft, fine white clay derivative of feldspar which is basically used for producing china and porcelain. Kaolin also finds use as filler in medicinal absorbents, textiles, paper, and soaps. This is aluminum silicate clay which is chemically inert and does not dissolve in water. The purpose behind adding Kaolin is to lend whiteness to the soap or detergent cake, resulting in the better cleansing of clothes and other items.

  1. Talc

 Talc is very much similar to Kaolin in terms of structure and properties, and is actually a magnesium silicate mineral. Like Kaolin, talc, also known as ‘talc powder’ is inert by nature and insoluble in water. Talc is mostly added to body soaps for imparting whiteness and helps in cleansing away dirt and grime from skin surface.

  1. Borax

Borax is added to detergent cakes and bars for making them more free-flowing. Chemically called sodium borate, Borax is largely used for cleaning purposes and has anti-fungal attributes as well. This compound transfers alkalinity or abrasiveness to the soap or detergent which results in better cleansing of clothes.

  1. Green Tea

Green tea extract is another filler that is more often added to soaps and has two distinct benefits. This extract is infused with caffeine that can go a long way in giving you the energy boost you need to kick off your day perfectly. The human skin has a particular affinity for caffeine, enabling the compound to be absorbed for taking advantage of its benefits.

Green tea also contains ECGC which is a kind of free radical that helps offset the skin’s ageing by preventing the formation of wrinkles. Antioxidants in green tea can help repair dying and damaged skin cells, thus enabling individuals to cope with numerous skin ailments like psoriasis and eczema.

Different kinds of additives too are used in soaps. For instance, the addition of glycerin transfers skin conditioning property to soaps.

Why Choose Custom Soap Manufacturing?

When it comes to choosing a quality soap brand, most of us usually end up buying a product based on the impressive packaging. Majority of the soaps that we see stacked up in supermarkets happen to be commercial brands. And unfortunately, almost all commercial soap brands are produced using artificial lathering agents, synthetic hardeners, and chemical detergents.

Such soaps do more harm than good, irritating and/or drying your skin and making it age prematurely. Since the skin is a very delicate and sensitive organ, you’d be much better off using handmade, organic soaps. Handcrafted soaps are made out of ingredients that are 100% organic, and hence very pure and completely free of harmful chemicals.

Handmade soaps are usually created via custom soap manufacturing processes or techniques. Following are 5 good reasons why you should use soaps that are crafted using bare hands.

Produced using ingredients that are natural and organic

Manufacturers and producers strictly ensure that they exclusively use natural/organic ingredients for churning out handmade soaps. In other words, ingredients like coconut oil, olive oil, avocado oil, and other essential oils are used in the manufacturing process. Natural colorants like purees and clays are used

Animals have not been used for testing the products

The handmade, organic soap brands that enjoy high demand always happen to be cruelty-free. In other words, these soaps neither contain any elements extracted from animals nor are tested on them. Goat milk, honey, and beeswax (derived from apiaries without killing bees) are the only animal-based products used in a handmade soap.


Since almost all ingredients in a handmade soap are natural and have a macrobiotic base, the components naturally happen to be biodegradable and hence do not contaminate the environment. COSCO is a primary producer of soap filler that are completely eco-friendly.

Promotes conditioning of the skin

All handmade soaps contain glycerin which is an extremely effective humectant, pulling moisture from the atmosphere and transferring the same to the skin. Glycerin which emerges as a byproduct during the saponification process, is completely natural, and is a superlative skin conditioner and moisturizer. COSCO Enterprises has been specializing in bespoke soap manufacturing since 1966, and the tincture green soap is one of its most popular tailor-made products.

Is soft and gentle on the skin

Since handcrafted soaps are free of chemicals and artificial additives or synthetic fillers, they tend to be gentle on the skin and never cause any irritation.

Variety in design and fragrance

Handmade soaps, like commercial soaps, are also available in a variety of designs, colors, sizes, and fragrances. A handmade soap can be easily made with the natural ingredients you prefer, including herbs, essential oils, and emollients. You can also select from an array of fragrances including but not limited to peppermint, citrus, lavender, and jasmine. The tincture green soap


The best thing about handmade soaps is that you can have them customized according to your preferences. For instance, you can pick the essential oils ideal for your skin type, and opt for further personalization by choosing the fragrances, colors, exfoliants, and so on. You can even make such soaps in your home.

How to Use Green soap?

Soap is an item that people use on a regular basis. There is a wide variety of soaps available in the market, each claiming to be better than others and consisting of properties that are beneficial for the consumers. However, it is a common observation that most soaps contain high amounts of chemicals that actually harm the skin rather than providing nourishment to it, as per their claims. Under such conditions there emerges a requirement for an alternative variety of soap that contains natural ingredients that are not harmful to the skin.

What is Green Soap?

Green soap is a variety of soap made of natural ingredients and has a glycerin base made of vegetable oil. The soap gets its name from the yellow or greenish tint that the soap acquires from the natural elements it is made of. Moreover, it is completely organic and biodegradable. The production of this soap is undertaken by custom soap manufacturing units as it is not readily available.

Custom Soap Manufacturing Uses

  • Household cleaning – Individuals try their best to keep their house clean. However, the chances of contamination by germs are way higher than the level that a person can tackle by regular cleaning. A mixture of green soap with water in a ratio of five to one can be used as a spray or water to clean or wipe the house. Its organic nature ensures that the house is not exposed to any harmful chemicals during the cleaning process.
  • Personal cleaning – Green soap manufacturing is also beneficial for personal cleaning. It can be used as body wash or hand wash. It is mild thus it does not cause harm to the skin. In comparison of the wide varieties of soap that contain chemicals and claim to be good for the skin, green soap provides nourishment to the skin in reality. People can also use it as a shampoo as it not only cleans the hair but gives it a soft and shiny feel as well.

The market has been flooded with new varieties of soap produced to keep up with the diverse preferences of the consumers. The custom soap manufacturing enterprises keep re-innovating methods of production to provide customers with a wider range of options than those that are already available.

Basic facts about custom soap manufacturing & Green Soap

Soap is one of the most common articles of daily use that is available in different shapes and compositions. They may be used for bathing, dishwashing or cleaning clothes. Over the years there have been many custom soap manufacturing companies that have evolved new and innovative methods to produce soaps and allowed consumers to choose from a wide range of options depending on the ingredients, fragrance, etc.

Basic composition and history of soap manufacturing

Over the years, soap has been known to serve many purposes such as curing skin sores, dying hair, serving as a skin ointment, etc. However, its primary function is to break away dirt from the surface when it dissolves in water due to the action of its components that include animal fat/plant oil and caustic soda.

It is believed that the use of soap was common in France, Spain and Rome much before it became common across the rest of Europe. The Celts, who were the ancient inhabitants of Britain, were also known to make soap. However, it may come as a surprise that in ancient times, there was a high tax levied on soap production as it was regarded as a luxury item and a symbol of status for the rich.

Soap fillers

At present, there is a wide range of options to choose from. Another important component is the soap filler that is made of substances that enhance the quality of the soap and make it more useful for a particular application. Kaolin, talc, glycerin and sodium silicate are all examples of soap fillers. Manufacturers may also add perfumes and essence to give the soap a fragrance that makes it more appealing to the consumers.

Green soap its advantages

A new variety of soap known as tincture green soap is fast gaining ground for its natural and non-chemical composition. It is a vegetable oil based and plant-based water friendly soap. It is safe and eco-friendly as it is not harsh on the skin due to the absence of chemicals. Thus it prevents the skin from drying and helping it to retain the moisture. The soap is green due to ectoplasmic coloring and the presence of glycerin as well as vegetable oil.

People who have recently got a tattoo or piercing on their bodies are advised to use green soap as it is effective in cleaning the area and does not contain chemicals preventing further damage to the wounded area.

Moreover, the non-corrosive quality of green soap allows artists to soak their equipment in the solution to clean it. Disinfectant soap cannot be used in case of a tattoo or piercing because it makes the skin dry leading to itchiness. Consumers may have the question “where can I buy green soap?” in mind. But the best thing is that green soap is widely available around the world at both online and offline stores.

To Lye or Not To Lye: The Truth About Soap Manufacturing

When talking about handmade soap or custom soap manufacturing, people often wonder whether natural and green soap contain lye. If you believe that soap should contain only organic ingredients, you are in for a disappointment. There is no soap without lye. Yes, lye is far from being organic but it’s a compulsory component of a soap that does what you want it to do: clean.

Thankfully, USDA confirms that lye is an allowable ingredient by its organic standards. However, there is a big difference between soaps made with lye and those that contain it. Promotional soap manufacturers know all too well about the role of lye in the soap-making process. Do you?

Is Lye Dangerous?

When most people think about lye, they imagine a harsh chemical, something that can ruin the skin when used on a regular basis. If you apply lye to skin in large quantities or drink it, it can be highly dangerous. However, you don’t use lye to your skin, you apply soap.

Soap is received as a result of a chemical reaction between lye and oil. During the reaction, the substances go through a transformation, which results in the creation of soap and natural glycerin. Both lye and oil are gone. The chemical reaction filed them as history.  So yes, lye is dangerous. No, you don’t come in contact with it when you use soap.

Sometimes soap manufacturers add more oil than needed for the chemical reaction in order to give the soap more moisturizing qualities and ensure that all the lye is gone.

Are There Alternatives?

When you hear soap manufactures say that they are using different soap fillers as lye alternatives, don’t swallow the bait. They usually claim that they use glycerin instead of lye. Now you know that glycerin appears as a result of a chemical reaction between oil and lye. Accordingly, they lie about the lye. Glycerin is vital to creating a base for the melt-and-pour* soap manufacturing process.

Changing the Perception

Knowing just few information tidbits about chemical reactions allows you to be smart about choosing your soap. There is no need to be afraid of the word lye when it comes to soap manufacturing process. Soaps made with lye are great for your skin. Professional soap makers use lye to create great cleansing and moisturizing products.

Don’t Touch The Lye

No matter how educated the public is, some still believe that if you touch lye, it will immediately burn a hole through your finger. Of course, drinking or bathing in lye is strictly prohibited. However, a drop of lye on your hand won’t kill you.

Since there is no soap without lye, handmade soap makers often have to be exposed to it. It’s imperative to wear gloves and goggles when working with lye. But there is no reason to panic if you accidently touch it. Lye is similar to bleach or ammonia. Washing hand thoroughly is sufficient.

So, to lye or not to lye? To lye, of course! No lye = no soap.

The Pros and Cons of Two Popular Soap Manufacturing Processes

In the past decade, custom soap manufacturing has been on the rise. Many people prefer handmade soap and know which questions to ask the manufacturers. People are rediscovering the advantages of making soap at home or at least checking the ingredients used by the promotional soap manufacturers. Let’s talk about two popular soap making methods that can help you understand what the process is all about.

  1. Melt-and-Pour

The whole process is in the name. It involves melting and pouring. This is a simple choice for beginners and hobbyists. All you have to do is buy a soap base and melt it down. Then, other soap fillers, such as fragrances, are added to the mix and the solution is left in the molds to harden. Some people believe that this process can’t technically be called soap making since it’s not prepared from scratch.


  • A wonderful soap making method for beginners. You can even do it with children.
  • You don’t need safety gear since you don’t come into contact with lye.
  • It’s a very quick method. The soap hardens overnight or in a few hours.
  • Fragrance oils don’t ruin the melt-and-pour soap with time.
  • This method can create beautiful bars of soap. You can make pretty layers to create true masterpieces.


  • This type of soap usually contains too much glycerin and can produce glycerin sweating, ruining the beauty of the bar.
  • You can’t choose the base ingredients, such as oils and butter. You have to work with what you buy.
  • You can’t add fresh ingredients such as milk. In fact, most of the additives don’t work well with such soap.
  • The melt and pour soap hardens fast and doesn’t allow you to create swirls.
  • If the soap becomes too hot, it can burn and the base will be hard to work with.
  1. Cold Process

The processes for cold soap making allow you to make the soap from scratch. In most cases, it’s better to be left up to a professional. Some soaps, such as tincture green soap, are better off being made in a laboratory rather than at home. The cold process combines oil, lye, and other soap ingredients. This method provides the soap manufacturers a greater freedom of choice.


  • You can customize all the ingredients depending on your/a customer’s personal preference.
  • The cold process allows you to manipulate the substance to create beautiful soap bars that include layers and swirls. It provides you with an opportunity to use your imagination.
  • The soap mass is thick enough to accommodate heavy ingredients/additives.
  • This process creates a more natural soap than the melt and pour


  • You need to work with lye, which requires certain safety measures and can become dangerous when used the wrong way.
  • This is a long process, which may take up to 6 weeks.
  • Not all fragrance oils are suitable to be used with this soap-making process.
  • Glitter can’t be placed inside the soap.

The process involves a long cleanup.
