Problems solved by technology

However, after adding an acidic substance to the commonly used polymer thickener system, the system will collapse (the consistency drops sharply, or the cold and heat stability is not good); or because the added amount is too large, such as poloxamer needs to add 10wt% Above, resulting in a strong smell, poor skin feel, and high cost; for example, a formula with 20wt% azelaic acid added will precipitate a large amount of azelaic acid crystals after storage at room temperature or low temperature for a certain period of time; adding 2 to 5wt% azelaic acid The formula of % salicylic acid has problems such as discoloration or poor stability

Abstract

The invention discloses a macromolecular thickening agent as well as a preparation method and application thereof, and belongs to the technical field of thickening. The high-molecular thickening agent is mainly prepared by synthesizing a monomer containing a taurine salt group and a monomer containing a carboxylate group. The polymer thickening agent has strong thickening ability in an acidic environment with pH of 2-4, can well thicken acidic nonionic raw materials, such as glycolic acid, lactic acid, salicylic acid, azelaic acid and the like, and significantly improves the storage stability of an acidic formula system; the formula containing 20wt% of azelaic acid does not separate out azelaic acid crystals after being stored for a long time at the normal temperature of 25-30 DEG C and the low temperature of 3-10 DEG C; and the formula containing 2-5wt% of salicylic acid is not easy to discolor, and relatively good stability can be kept for a long time. The high-molecular thickening agent also has certain emulsifying capacity, and a more stable emulsifying system can be obtained when the high-molecular thickening agent is compounded with a nonionic small-molecular emulsifier for use.

Description

technical field [0001] The invention belongs to the technical field of thickening, and in particular relates to a polymer thickener and its preparation method and application. Background technique [0002] In the cosmetics and pharmaceutical industries, polymer thickeners are generally used in formulations such as creams and essences, and play a role in thickening and suspending. Synthetic macromolecule thickeners have oil-soluble and water-soluble two categories, if not specified, the present invention refers to water-soluble polymer thickeners (hereinafter referred to as polymer thickeners). [0003] Among the polymer thickeners used in cosmetics and pharmaceuticals, carbomer is the most commonly used. In addition, there are Simugel series polymers from Seppic (such as Simugel EG), acrylamide copolymer Sepigel 305, xanthan gum, locust bean gum, and less commonly used ones are Poloxamer 407 and Poloxamer 184. [0004] In recent years, with the introduction of relevant law...
