Abstract

The invention discloses a preparation method of cream emulsion cosmetics without adding surfactant and belongs to the technical field of high polymer material and applied chemistry. Amphipathy random polymer micellar solution is used as emulsifier to replace surfactant for emulsification in cosmetics, and skin irritation caused by the surfactant in cream emulsion cosmetics is avoided. Amphipathy random polymer is prepared by copolymerization of hydrophobicity monomer methyl methacrylate and hydrophilicity monomer methacrylic acid. Under pH inducement, random polymer forms micelle in aqueous phase by self-assembling. The polymer micelle water phase is mixed with oil phases such as jojoba oil, mink oil, caprylic / capric triglyceride, white oil and silicone oil, oil-in-water type cream emulsion cosmetics are formed by shearing with a high-speed dispersion instrument, and the stability of the oil-in-water type cream emulsion cosmetics meets the requirements of cosmetics.

Description

technical field [0001] The invention discloses a method for preparing cream emulsion cosmetics without surfactant, which belongs to the technical field of polymer materials and applied chemistry. Background technique [0002] Surfactants have a series of properties such as wetting, emulsifying, solubilizing, dispersing, decontaminating, penetrating, etc. They are widely used in cosmetics and are an indispensable part of them. However, the safety of surfactants, especially the irritation to skin, eyes and hair deserves attention. The irritation of surfactants to the mucous membrane is mainly caused by dissolution, penetration and reactivity, while the irritation to the skin is believed to be the direct cause of the penetration of surfactants on the skin. The eye and skin irritation potential of surfactants was studied by A. Mehling et al. Cocoa glucoside, lauryl glucoside, lauryl glucose carboxylate, sodium lauryl ether sulfate, lauryl Surfactants such as sodium lauryl...
