Abstract

The invention provides a salicylic acid solubilizing slow-release composition. The salicylic acid solubilizing slow-release composition is prepared from a specific proportion of active ingredient salicylic acid, solubilizing slow-release agent poloxamer 407, a humectant, a skin feeling conditioning agent, a preservative system and deionized water. The salicylic acid solubilizing slow-release composition has the advantages that under the conditions without alcohol and at a low pH value, the salicylic acid is prepared into a stable, easy-to-use and low-irritant water-soluble liquid, gel, or an intermediate state between the water-soluble liquid and the gel; on one hand, the solubility of the salicylic acid in an aqueous phase can be significantly improved, thereby increasing the biological utilization rate of the salicylic acid, on the other hand, the irritation of the salicylic acid to the skin can be significantly reduced, thereby solving the technical problem of the high-concentrationsalicylic acid intolerance of wide crowds. In addition, the invention further relates to a preparation method and application of the salicylic acid solubilizing slow-release composition.

Description

technical field [0001] The invention belongs to the technical field related to cosmetics and its preparation, and specifically relates to a water-soluble solubilizing buffer whose main components are composed of salicylic acid and poloxamer, and which include moisturizing agent, skin feeling regulator, antiseptic system and deionized water. release formulations, preparation methods and uses. Background technique [0002] Salicylic acid, also known as salicylic acid, is a beta hydroxy acid (BHA) extracted from plants such as willow or poplar with the formula C 7 h 6 o 3 , in the form of white fine needle crystals or white crystalline powder, with antipyretic, analgesic and anti-inflammatory effects. Salicylic acid has lipophilic properties, can penetrate pores and dissolve dead skin cells, and is often widely used in cosmetics as an exfoliating agent. Specifically, salicylic acid can be used to treat dandruff, pimples, blackheads, acne, skin wrinkles, skin pigmentation, b...
