Polyhydroxypropyl arginine and its derivative polyhydroxy saccharide compound as well as preparation method and application thereof

Abstract

The invention discloses a polyhydroxypropyl arginine and its derivative polyhydroxy saccharide compound as well as a preparation method and application thereof. The polyhydroxypropyl arginine and its derivative and polyhydroxy saccharide are associated through hydrogen bonds to form a composite structure. The polyhydroxypropyl arginine and its derivative are active components formed by fusing glycerol, arginine and derivatives thereof; the glycerin is an efficient moisturizing component; the arginine and its derivative are natural moisturizing factor components, positive charges carried by the arginine and its derivative generate strong electrostatic adherence force with skin or damaged hair, combining with hydroxyl oxygen of the glycerin part and nitrogen groups of the arginine and the its derivative, hydrogen bonds can be easily formed with other hydrogen bond donors such as the skin or the damaged hair, and a long-acting and lasting moisturizing effect is achieved. A special composite structure and the cationic electrostatic interaction of the polyhydroxypropyl arginine and its derivative are further utilized to achieve more efficient interface adsorption performance, the moisturizing performance is good, the skin feeling is excellent, which can be applied to various daily chemical washing care and skin care formula systems.

Description

technical field [0001] The invention relates to the technical field of daily chemical products, in particular to a polyhydroxypropyl arginine and its derivative-polyhydroxy sugar complex as well as its preparation method and application. Background technique [0002] Efficient and long-lasting moisturizing properties are one of the important concerns of cosmetic formulations. Due to various external stimuli, including environmental damage, the skin epidermal cells are damaged, and the damaged skin epidermal cells are prone to dry skin and lack of water. Conventional small molecule moisturizers can bring immediate hydration to the skin, but cannot achieve long-lasting hydration. However, the use of closed moisturizers such as vaseline and white mineral oil in traditional cosmetics cannot give the skin sufficient air permeability, but it is easy to block pores, and oily skin is prone to pimples and acne. Bioactive sugar is a kind of natural active ingredients with good bioco...

AI Technical Summary

Problems solved by technology

[0009] (1) The adsorption performance and deposition efficiency of humectant and skin / hair surface are low;

[0010] (2) Modification and modification of biologically active sugars by biochemical methods are complex and have many application limitations;

[0011] (3) It is difficult to form an effective intermolecular network composite membrane structure. In particular, the prior art also clearly records that the hydrogen bond force between most common amino acids and biologically active sugar molecules is very weak, and cannot form a good composite hydrogen key structure
