Problems solved by technology

[0004] However, due to structural problems, these polymer emulsifiers have more or less flaws, and are subject to many restrictions in use.
For example, there are more or less unreacted moderately toxic acrylamide monomers in acrylamide polymer emulsifiers (such as Sepigel305), and because acrylamide monomers are too active, the resulting ultra-high molecular weight polymer chains are in the It is easy to break under high-speed shearing or ultraviolet radiation; for Pemulen TR-1 and TR-2, because of the high proportion of acrylate introduced into the polymer chain (the finished product is easy to jelly, the thickening ability is not strong, The powder is difficult to disperse and easy to be damp and hard) which limits the range of use of this series of polymers

Abstract

The invention discloses a novel macromolecule emulsifier for cosmetics. The macromolecule emulsifier id characterized by being prepared from following components by weight: a component 1, a component 2, inorganic alkali, a crosslinking agent, an initiator, grease, an oil-in-water emulsifier and deionized water. The component 1 is the vinyl long-chain alkyl ether, acrylic long-chain alkyl ester or methacrylic acidalkyl long-chain alkyl ester with a total number of carbon atoms of 12-34; the component 2 is acryloyl dimethyl taurine; the crosslinking agent is a polyol or an organic compound containing more than two unsaturated double bonds. The invention uses monomer containing sulfonate group as a main component to design and synthesize a macromolecule emulsifier with strong thickening and emulsifying abilities; paste, cream and emulsion products produced from the emulsifier are soft and smooth on skin and do not cause greasy feeling.

Description

technical field [0001] The invention relates to an emulsifier, in particular to a polymer emulsifier used in cosmetics and a preparation method thereof. Background technique [0002] In the cosmetics industry, polymer emulsifiers are generally used in cream emulsion formulas to thicken, emulsify, suspend and moisturize. Synthetic polymer emulsifiers can be divided into two categories: oil-soluble and water-soluble. If there is no special description, the present invention refers to water-soluble polymer emulsifiers. [0003] Among the commonly used water-soluble polymer emulsifiers for cosmetics (hereinafter referred to as polymer emulsifiers), the earliest appeared was the Pemulen series of polymer emulsifiers launched by BFGoodrich, namely acrylic acid / C10-30 alkyl acrylate Cross-linked copolymers Pemulen TR-1 and Pemulen TR-2, the difference between the two is that the thickening and rheology are slightly different. After that, many companies launched a series of polyme...
