Problems solved by technology

However, the compatibility between water-based film formers and oil-based film-formers is poor, which makes it difficult to adjust the formula, and after the film-forming of acrylic film-formers, good elasticity and good skin-sticking effect are guaranteed, and film-forming Insufficient rigidity, when encountering acne-prone skin, it is necessary to add a large amount of fillers to ensure its concealing effect. The film-forming material itself cannot provide help for the improvement of concealing effects, and too much inorganic fillers increase the risk of pore clogging. risk
[0006] To sum up, the existing public technology cannot meet the requirements of concealer, moisturizing, long-lasting makeup, skin feeling, easy makeup removal, etc. Consumers will cause various skin problems during use

Abstract

The invention discloses a BB cream containing a non-ionic silicon-containing modified aqueous polyurethane dispersion. The BB cream includes the following components: a non-ionic silicon-modified aqueous polyurethane dispersion, a pretreatment color paste, an emulsifier, a thickener, a polyol moisturizing agent, an emollient oil, water, and optional Auxiliary. The non-ionic silicon-containing modified aqueous polyurethane dispersion is prepared by reacting raw materials including a diisocyanate-terminated prepolymer, a macromolecular siloxane and an amine chain extender. The non-ionic silicon-containing modified aqueous polyurethane dispersion is applied in BB cream products, which helps to simultaneously achieve the effects of concealing, good skin feel, long-lasting makeup and easy makeup removal.

Description

technical field [0001] The invention relates to the field of personal care, in particular to a BB cream, and more particularly to a non-ionic silicon-containing modified aqueous polyurethane dispersion. Background technique [0002] BB cream, because of its combination of foundation, sunscreen and isolation products, is becoming more and more sought after by beauty-loving women and has become a fashion trend. [0003] BB cream (Blemish Blam) originated in Germany. It was originally designed by Germans for patients receiving laser treatment. It has a thick texture and contains skin care and sunscreen ingredients, which can repair and regenerate damaged skin. Only after it was developed and developed, did it become a daily cosmetic product from a medical beauty product, and it evolved into a single product with functions such as concealer, isolation, sun protection, face repair, and base makeup. [0004] The existing BB creams on the market are all water-in-oil emulsification...
