INCI system (International Nomenclature of Cosmetic Ingredients) is a nomenclature of cosmetic ingredients existing in accordance with the law of the European Union. It creates a standardized system of indicating ingredients on cosmetic packagings. The INCI order assumes that the names of the ingredients are listed, starting with the substance used in the highest amount, and ending with the substance of the lowest concentration. Lauryl Betaine is the name of this compound derived from this system.
Lauryl Betaine is an amphoteric surfactant which is a derivative of N-dodecyl-N, N-dialkanolamine with a strong protein denaturing effect. Lauryl Betaine, derived from vegetables, is a clear to pale yellow liquid. The chemical name of this compound is dodecyldimethylammonium carboxylatomethyl. It is a hydrophilic and water-soluble substance. Depending on the pH of the environment, it has different properties. The fact that we have a wide range of this indicator at our disposal is an additional advantage. The compound is of natural, plant origin and is completely biodegradable.
The substance is classified as: antistatic, cleansing, nourishing skin and hair and a surfactant. In cosmetics, it has several functions. Among other, it acts as a conditioning and antistatic ingredient. In addition, it soothes the irritating effects of anionic detergents and intensifies foaming. As a wetting agent, it facilitates the removal of dirt in contact with the skin. Lauryl Betaine also binds water-soluble substances and helps to introduce fatty components, being sparingly soluble in this medium, into aqueous solutions. In other words, it improves the quality and stability of foam facilitating its penetration through oil and dirt. Additionally, it acts as a viscosity modifier and an emulsion-generating substance. Thanks to so many functions in cosmetics, Lauryl Betaine is found in shampoos, body washes/cleansers, exfoliating products, facial cleansers, beard cleansers, creams and products containing SPF. It belongs to the most common cosmetic ingredients and has a very gentle effect on the skin. Thus, it is especially recommended in preparations for sensitive skin.
The use of Lauryl Betaine is not limited to cosmetic preparations. Thanks to its good detergent and dispersing properties, it is used in the production of both specialized and basic detergents. Among others, it is applied in the production of detergent concentrates or dish washing liquids.
Lauryl Betaine is a safe substance designed for use in cosmetic preparations. The substance is irritating to the skin, but is not irritating to the extent that it is harmful to the health. The problems of potential allergy have not been defined, but this is usually an individual matter. The Cosmetic Ingredient Review (CIR) warns that preparations with Lauryl Betaine should contain appropriate concentrations of substances specified in the guidelines. A number of restrictions have been imposed by law. These are divided into many criteria that systematize the use of this substance on the market. Based on the tests, it is not suspected that the substance has a negative effect on the environment or that it bioaccumulates.
