Cosmetic Grade Sodium Lauroyl Sarcosinate Liquid CAS 137-16-6
Products Description
- Sodium Lauroyl Sarcosinate is an amino acid derived surfactant widely used in personal care and cosmetic products. It is a sodium salt formed by the reaction of lauric acid and taurine (Sarcosine) and has good cleansing and mildness.
- Sodium Lauroyl Sarcosinate has good water solubility because its hydrophilic groups can form hydrogen bonds and other interactions with water molecules. It can also dissolve to some extent in organic solvents such as ethanol and propylene glycol, though its solubility in them is relatively weaker than that in water. This solubility characteristic enables it to play a role in a variety of formulation systems, whether they are aqueous formulations or formulations containing some organic solvents.
- Sodium Lauroyl Sarcosinate produces rich, fine, and stable foam. When used in cleansing products (such as facial cleansers, body washes, etc.), it can quickly generate a large amount of foam, which can effectively wrap and remove dirt, oil and other impurities, and will not disappear easily within a certain period of time, providing good support for the cleaning process.

Function
- Surfactant: As an anionic surfactant, Sodium Lauroyl Sarcosinate effectively reduces the surface tension of water, helping cleaning products remove dirt and grease.
- Mildness: Compared to traditional surfactants, Sodium Lauroyl Sarcosinate is generally milder to the skin and is suitable for sensitive skin, reducing the risk of irritation and allergies.
- Foaming agent: It can produce rich foam and enhance the product experience. It is commonly used in shampoo, shower gel and facial cleanser.
- Emulsifier: In some formulations, it can also act as an emulsifier to help the oil and water phases mix to form a stable emulsion.
Application
- Personal Care Products
Sodium Lauroyl Sarcosinate is a commonly used ingredient in personal care products. In facial cleansing products, it can gently clean the skin, effectively remove dirt, oil and makeup residues on the skin surface, and is less irritating to the skin, suitable for all skin types.
In body washes, Sodium Lauroyl Sarcosinate can produce rich foam, providing users with a comfortable bathing experience and preventing the skin from drying.
In hair care products such as shampoos, Sodium Lauroyl Sarcosinate helps to clean the hair and scalp, reduces the greasiness of the hair, and can also improve the softness and luster of the hair.
- Oral Care Products
Sodium Lauroyl Sarcosinate is also used in oral care products such as toothpaste. It can act as a foaming agent to produce rich foam and enhance the cleaning experience during tooth brushing. Meanwhile, it also has certain antibacterial properties, which helps to inhibit the growth of bacteria in the mouth and maintain oral health.
- Industrial and Household Cleaning Products
Sodium Lauroyl Sarcosinate also has applications in industrial cleaning and household cleaning products. For example, in the cleaning of metal surfaces, it can effectively remove oil and dirt and is less corrosive to metal surfaces. In household cleaning products (such as dishwashing detergents, floor cleaners, etc.), it can provide good cleaning effects and the foam it generates helps the cleaning process proceed smoothly.
Summary
Sodium Lauroyl Sarcosinate is a multifunctional surfactant that has multiple effects such as cleansing, foaming and mildness. Its wide application in personal care and cosmetics makes it one of the most important ingredients in modern skin care and cleansing formulations.
