Temperature-sensitive change gel spray composition and preparation method thereof

By constructing a thermosensitive gel spray by combining low-acyl and high-acyl gellan gum, and combining divalent cation regulation and Schiff base reaction, the problems of uneven spraying, rapid evaporation and irritation of existing moisturizing gel sprays are solved. This achieves long-lasting water retention, self-repair and skin microecological regulation, improving the user experience and skin health.

AI Technical Summary

Technical Problem

Existing moisturizing gel spray products are viscous and prone to clogging at room temperature, resulting in uneven spraying, rapid evaporation of moisturizing ingredients, strong irritation from cooling ingredients, inability to lock in moisture for a long time, and neglect of the skin's microecological balance, leading to a poor user experience and damage to the skin barrier's homeostasis.

Method used

A thermosensitive gel system was constructed by combining low-acyl gellan gum and high-acyl gellan gum, and combined with divalent cation regulation to form a thermoresponsive composite gel. Oxidized hyaluronic acid was added to form a Schiff base reaction with chitosan to achieve self-repair. Thermosensitive liposomes were added to release fructooligosaccharides, and combined with menthyl lactate and rose essential oil nanoemulsion to regulate the skin microecology.

Benefits of technology

It achieves low-viscosity fluid spraying at room temperature, formation of a transparent and strong gel film, long-lasting water retention and sustained release of active ingredients, self-repair function, promotes the growth of beneficial bacteria, and improves skin health and user comfort.

Abstract

The invention discloses a temperature-sensitive change gel spray composition and a preparation method thereof, and belongs to the field of gel spray. The temperature-sensitive change gel spray composition provided by the invention is prepared by the following steps: firstly, dissolving soybean lecithin and cholesterol in a solvent, adding a fructo-oligosaccharide aqueous solution to prepare a temperature-sensitive liposome, and meanwhile, mixing low-acyl gellan gum, high-acyl gellan gum, xanthan gum and deionized water I to form a solution; sequentially adding a humectant, trehalose, panthenol and menthyl lactate into the solution, and mixing to form a main water phase; adding oxidized hyaluronic acid into the main water phase, then adding a chitosan-lactic acid mixed solution to adjust the pH value, and continuing to add temperature-sensitive lipidosome and rose essential oil nano-emulsion for mixing; and finally, adding a calcium chloride solution and deionized water II, and filtering. The gel spray composition provided by the invention has excellent moisturizing capacity and film-forming property, can regulate micro-ecological balance, and realizes refreshing spray experience and long-acting moisturizing.
