Sodium Lauroyl Glycinate is a surfactant that is a representative of the group of amino acid surfactants. Most often, it acts as a substance with washing properties, which also works well as an emulsifier. Due to its characteristics, it is mainly used in face and body cleansing products, as well as in shampoos. It is readily used in various industries such as cosmetics, detergents, household and industrial cleaning.
Sodium Lauroyl Glycinate (C14H26NO3) is the INCI name of an anionic surfactant from the group of amino acid surfactants. This compound is a reaction product of C8-C18 acid chlorides (molecules having an even number of carbon atoms) with glycine and sodium hydroxide. Alternative names for this substance include N-Lauroylglycine sodium salt. Sodium Lauroyl Glycinate exists both as a solid and in the form of an aqueous solution, with an active substance concentration of about 20%. It is produced on the basis of biomimetics, which are raw materials that imitate naturally occurring chemical compounds and fatty acids — raw materials of natural origin. Sodium Lauroyl Glycinate is a substance that is well soluble in water. In the form of an aqueous solution, its colour ranges from straw to light yellow.
Sodium Lauroyl Glycinate is a safe, amino acid-based surfactant. It provides excellent chemical stability and is known for a skin-friendly pH that does not cause additional irritation. It is characterized by low toxicity towards human skin cells.
Sodium Lauroyl Glycinate is an agent with cleansing properties and supports the formation of foam, which intensifies the effectiveness of many cosmetic products. It is often chosen as one of the substrates for cosmetic formulations due to its gentleness on human skin and its remarkable effectiveness. It can be used together with SLS-containing and SLS-free preparations. Sodium Lauroyl Glycinate has mild degreasing properties that help restore long-lasting softness and hydration to the skin. Due to its smoothing properties, it is readily used in haircare preparations. Smoothing the hair follicles gives a quick effect of well-nourished and smooth hair. This compound also has antistatic properties (prevents static and frizz), which additionally increases its usefulness in haircare products such as shampoos and conditioners. In addition, this compound plays a preservative role in care products and reduces the highly irritating effect of other substances.
Sodium Lauroyl Glycinate can be found among the ingredients of shampoos, face cleansers for children and adults, bath lotions and toothpastes. In addition, it is used in intimate hygiene lotions and make-up removal products.
Sodium Lauroyl Glycinate is a highly active substance, but at the same time it is very gentle to the skin. Using this substance should not cause allergic reactions. This ingredient has been shown to be non-irritating and non-sensitizing when applied to human skin in amounts up to 15% for rinse-off detergents and 5% for leave-on products. It is approved for use in cosmetics, even those intended for the care of children.
