Hyaluronic acid treatment powder dispersed in oil phase as well as preparation method and application of hyaluronic acid treatment powder

Abstract

The invention discloses hyaluronic acid treatment powder dispersed in an oil phase as well as a preparation method and application thereof, and belongs to the technical field of cosmetics. The powder comprises the following components in parts by weight: 100 parts of at least one of synthetic fluorophlogopite, mica, sericite, talcum powder, silica and titanium dioxide; 1-5 parts by weight of at least one of hydrolyzed hyaluronic acid with a molecular weight of 400,000 Daltons or less and sodium hyaluronate; 1 to 5 parts by weight of lauroyl lysine; and 1 to 10 parts by weight of at least one of triethoxyoctylsilane and polydimethylsiloxane. According to the hyaluronic acid treated powder dispersed in the oil phase and the preparation method and application thereof, the hyaluronic acid is subjected to oleophylic treatment and then grafted with basic powder which is used in makeup massively, so that the problem of addition and use of the hyaluronic acid in makeup products is solved, and the hyaluronic acid treated powder is easy to disperse uniformly and can be used for preparing cosmetics. And the moisturizing function can be fully exerted.

Description

technical field [0001] The invention relates to a hyaluronic acid-treated powder dispersed in an oil phase, a preparation method and application thereof, and belongs to the technical field of cosmetics. Background technique [0002] Hyaluronic acid, also known as hyaluronic acid, has a molecular formula of (C 14 h 21 NO 11 ) n , is a disaccharide unit glycosaminoglycan composed of D-glucuronic acid and N-acetylglucosamine. Hyaluronic acid is a biochemical drug with high clinical value, and is widely used in various ophthalmic operations, such as lens implantation, corneal transplantation and anti-glaucoma surgery. It is also used to treat arthritis and accelerate wound healing. Used in cosmetics, it can play a unique role in protecting the skin. It can keep the skin moist, smooth, delicate, soft and elastic. It has the functions of anti-wrinkle, anti-wrinkle, beauty care and restoration of skin physiological functions. [0003] As a moisturizing raw material, hyaluroni...

Problems solved by technology

[0003] Hyaluronic acid is widely used in skin care as a moisturizing material. Because hyaluronic acid is a powerful hydrophilic material, it is easily soluble in water, but it is difficult to disperse in oil.

At the same time, due to the strong ability of hyaluronic acid to bind water, it is very difficult to adjust its viscosity in cosmetics

Make-up base makeup is usually a water-in-oil formula, with very little water added, and powder products usually do not add water, so it is almost impossible to add hyaluronic acid to these products. On the one hand, due to the low water content Even not, hyaluronic acid has no medium for dissolution and dispersion. On the other hand, even if it is water-soluble, the viscosity of hyaluronic acid combined with water is particularly high, which makes it difficult to mix the system, and the viscosity cannot be adjusted. Hyaluronic acid can only be used in thousand percent Even a few ten-thousandths of the content, and can not achieve the effect
