Preparation and production method of high-purity emulsion type cosmetics

High-purity oil and water phases were prepared by supercritical extraction and deep purification. Combined with a nano-silica stabilized interface film and dynamic pressure stirring, the problems of skin irritation and uneven particle size distribution caused by excessive emulsifier were solved. This achieved high stability of the emulsion and continuous release of active ingredients, thus improving the safety and efficacy of cosmetics.

AI Technical Summary

Technical Problem

In the production of traditional emulsion-type cosmetics, excessive use of emulsifiers leads to a high risk of skin irritation, and uneven particle size distribution affects the skin feel and release of active ingredients, making it difficult to fully exert their effects.

Method used

High-purity oil and aqueous phases are prepared by supercritical extraction and deep purification, combined with a nano-silica stabilized interface film and dynamic pressure stirring, and microencapsulation technology is used to encapsulate active ingredients to form an emulsion with uniform particle size.

Benefits of technology

The amount of emulsifier used was reduced, which improved the stability and uniformity of the emulsion, promoted the continuous release of active ingredients, and enhanced the safety and efficacy of the product.

Abstract

The invention discloses a preparation and production method of a high-purity emulsion type cosmetic, and aims to solve the problem that in order to ensure that an emulsion has enough stability, the dosage of an emulsifier is often increased, and the skin is irritated. In addition, the emulsion formed by a conventional process is relatively wide in particle size distribution, and non-uniform particle size distribution has negative effects on the skin feeling of the product. According to the technical scheme, the preparation and production method of the high-purity emulsion type cosmetic is characterized by comprising the following steps of emulsion oil phase preparation, emulsion water phase preparation, nanocrystalline seed preparation, emulsion preparation, dynamic pressure stirring, active microcapsule preparation, mixing and blending, and cooling and filling. According to the preparation and production method of the high-purity emulsion type cosmetic, the oil-phase and water-phase raw materials are subjected to purification treatment, nano silicon dioxide with good compatibility with the oil phase and the water phase is added, dynamic stirring is performed, and the microcapsule technology and other formulas and processes are adopted, so that the stability is ensured, and meanwhile, the dosage of an emulsifier can be reduced; the release and utilization rate of active ingredients are promoted.
