Anionic Surfactant Ingredients or Chemicals
Sancolo Product Page
Description of Anionic Surfactant: surfactants (Surface Active Ingredients) are ingredients used to reduce the surface tension between different substances. They function in many different ways such as dispersants, emulsifiers, detergents, wetting agents and foaming agents. Almost all Surfactants have the same structure, a long, hydrophobic tail and a hydrophilic head. The tails are very similar in most surfactants, the difference lies mainly in the hydrophilic head. This head can either be nonionic, anionic, cationic or amphoteric.
Anionic Surfactants contain a negatively charged head, this aids in the formation of stable micelles. When mixed with water, this class of surfactants creates a lot of foam. Common Anionic Surfactants are sulfates, like SLS (Sodium Lauryl Sulfate) or SLES. Anionic surfactants are mostly used in soaps (for example Ssucate DSL30) and detergents (for example PhosEster 2EH 3EO) where a high quantity of foam is desired. A disadvantage of most Anionic Surfactants is that they are less suited for oily emulsions, they also cannot be used in combination with Cationic Surfactants.
Surfactants have a long history in personal care products, dating back to ancient times. For example, the ancient Egyptians used a form of soap made from a mixture of animal and vegetable oils, as well as alkaline salts like sodium carbonate. Similarly, ancient Greeks and Romans used soap-like materials made from animal fats and ashes.
In the modern era, a wide range of surfactants has been developed and used in personal care products, including anionic, nonionic, cationic, and amphoteric surfactants. These surfactants are an essential part of almost all modern personal care products and cosmetics, such as shampoos, body washes, facial cleansers, and toothpaste, to name a few.
Among the hundreds of dazzling surfactants in the modern personal care industry, the two most widely used and manufactured surfactants are sodium lauryl sulfate (SLS) and its derivative, Sodium lauryl ether sulfate(SLES). They have been the workhorse surfactants for decades since they were introduced in the s, for their outstanding ability to create a rich lather and effectively remove dirt and oil from the skin and hair. Both SLS and SLES are sulfate-based surfactants. And they have caused more and more concerns related to skin irritation, cancer-causing, and environmental impact.
In recent years, there has been increasing interest in using more skin-friendly and sustainable green surfactants in personal care products. Sulfate-free products are gaining more and more attention, and market share. This has led to the development of new surfactants that are milder, non-toxic, biodegradable, and renewable, as alternatives to SLS and SLES.
Amino acid-based surfactants are considered promising alternatives to replace SLS and SLES in sulfate-free formulations.
Amino acid-based surfactants, also commonly called Amino acid surfactants(AAS), are a class of anionic surfactants derived from natural amino acids, which are the building blocks of proteins. They are considered to be more biocompatible with human skin and environmentally friendly than many other types of surfactants.
These surfactants can be commercially synthesized by reacting an amino acid with a fatty acid or its derivatives, such as a fatty acid methyl ester. The resulting compound has both a hydrophilic (water-loving) and a hydrophobic (water-repelling) end, allowing it to reduce surface tension and form stable emulsions in water-based systems.
Amino acid surfactants are readily biodegradable, non-toxic, and renewable, and they tend to be less irritating to the skin and eyes. They have similar lathering and cleaning abilities to SLES, but they do not over-strip lipids from our skin and scalp, which makes them more skin-friendly than sulfate-based surfactants.
In recent years, Amino acid surfactants are gaining more and more attention for their advantages over traditional sulfate surfactants. Their advantages include:
Overall, amino acid-based surfactants offer a range of benefits that make them an attractive alternative to traditional surfactants in many applications.

Get a QuoteResearch has shown that amino acid-based surfactants can provide comparable or even superior performance to traditional surfactants. They exhibit excellent foaming, wetting, and emulsifying properties, making them suitable for a variety of applications.
Amino acid-based surfactants have unique properties that make them effective at cleaning and gentle on the skin. Unlike traditional surfactants, which can strip the skin and hair of their natural oils, amino acid-based surfactants help to maintain the skin and hair&#;s natural moisture levels. This is due to their similar structure to the natural lipids found in the skin, which allows them to mimic the skin&#;s natural barrier function.
Furthermore, because amino acid-based surfactants are derived from natural sources, they do not contain harmful chemicals or irritants that can cause skin irritation or other adverse effects.
Despite the long-listed advantages of Amino acid surfactants over traditional surfactants, until now, their usage in personal care products is still far behind traditional SLES surfactants. Why is that? A few reasons may include:
There are a variety of amino acid surfactants available, each with unique properties that make them effective in different applications. In this section, we will explore the top 5 amino acid surfactants that are commonly used in personal care products, and discuss their benefits and properties.
Sodium Lauroyl Sarcosinate, often known as Sarcosyl, is one of the most widely used amino acid-derived surfactants. It is derived from coconut oil and sarcosine. Sodium Lauroyl Sarcosinate is widely used as a primary or secondary anionic surfactant in toothpaste, facial cleansers, ultra-gentle shampoos, and baby bath bubble lotions.

Yeser® LS30Disodium Laureth Sulfosuccinate, also known as DLS for short, is a very mild, non-irritating anionic surfactant. It features excellent detergency, yet with medium degreasing power, which enables the final product to clean well and leaves the skin and hair a delicate feeling after washing. DLS is considered by far the best choice of a primary surfactant to formulate sulfate-free gentle hair and skin care products.
Yeser® MS50Sodium Cocoyl Glycinate is considered one of the mildest anionic surfactants by far, yet with excellent foaming and cleaning abilities. It is derived from the amino acid glycine and coconut fatty acids. Glycine is the smallest amino acid, and it gives Sodium Cocoyl Glycinate a smaller and lighter-charged hydrophilic head compared to all other anionic surfactants.
Compared with other anionic surfactants, Sodium Cocoyl Glycinate also removes less intercellular cement lipids when applied, which makes it skin barrier friendly.
Yeser® GC30SSodium Methyl Cocoyl Taurate, commonly called SMCT for short, is a very mild, non-toxic, high-safety anionic surfactant for personal cleaning products. It has excellent water solubility, hard water resistance, and good effectiveness in a wide pH range. Sodium Methyl Cocoyl Taurate has similar cleaning and foaming abilities to Sodium Lauryl Ether Sulfate(SLES), but is much low irritating and safer for the skin and eyes.
Yeser® SMCT35SPotassium Cocoyl Glycinate, like its &#;sister&#; Sodium Cocoyl Glycinate, is another Glycine amino acid-based surfactant. They have similar properties, only that Potassium Cocoyl Glycinate has better solubility, which makes it even easier to rinse off, although Sodium Cocoyl Glycinate is already easy to rinse off.
It produces a pleasant creamy-feeling lather during washing. After washing, it can leave the skin with a clean, light, supple, and non-drying feel.
