Abstract

The invention discloses L-carnitine dodecyl alkyl sulfonate, a preparation method and the application thereof. The L-carnitine dodecyl alkyl sulfonate has double efficacy of moisturizing beauty and cleanliness, and is a preferred main material of detergent, compound soap, dish washing detergent and non-phosphate detergent. The preparation method is: L-carnitine hydrochloride is dissolved in ethanol, heated up to 20-60 DEG C, and dodecyl alkyl sulfonate is added; stirring and reacting last for 2-8 hours; L-carnitine dodecyl alkyl sulfonate is obtained after temperature reduction and crystallization, filtering, concentration and crystallization of mother liquor. Combination containing L-carnitine dodecyl alkyl sulfonate is applicable to cosmetics, skin care, oral care, face cream, facial mask, perfumed soap, hand-washing liquid, bath product, hairdressing and hair care, bathing supplies, and fruit and vegetable tableware cleaning products.

Description

technical field [0001] The invention relates to a dodecyl sulfonate surfactant, in particular to a kind of L-carnitine dodecyl sulfonate and its preparation method and application, which belongs to the preparation technology of surfactant and is suitable for the preparation of Various washing cosmetics. Background technique [0002] Surfactant refers to a class of compounds that can significantly reduce the surface tension of water at a very low concentration. A series of physical and chemical effects such as antistatic and corresponding practical applications. Surfactants are also widely used in the pharmaceutical industry: in pharmaceuticals, many insoluble drugs such as volatile oil-soluble cellulose and steroid hormones can form transparent solutions and increase concentrations through the solubilization of surfactants; they can be used as fungicides and The use of disinfectants, their bactericidal and disinfection effects are due to their strong interaction with bacte...
