A composition containing aqueous nonionic polyurethane dispersion and its preparation method

Abstract

A composition comprising aqueous nonionic polyurethane is provided, comprising (a) 0.1 to 30 parts by weight of aqueous nonionic polyurethane dispersion; (b) 10 to 30 parts by weight of detersive surfactant; (c) 0.01 to 5 parts by weight Conditioning agent in parts by weight; (d) aqueous carrier to 100 parts by weight. The composition of the present invention is used as a shampoo, which can make the hair strong and strong naturally, and can also prolong the duration of the fullness of the hair.

Description

technical field [0001] The invention belongs to the field of cleaning and care, and relates to a composition containing water-based nonionic polyurethane. Background technique [0002] With the continuous improvement of living standards, people continue to put forward new demands for personal cleaning products. At present, hair loss, less hair and damaged hair have become the most important problems in the field of hair care. It is the simplest and most effective way to solve these problems by using shampoo. [0003] Hair is mainly composed of epidermis, cortex and medulla from outside to inside.

If the cuticles on the hair are aligned, more light will be refracted, and the hair will look beautiful; if the cuticles are scratched or damaged, the hair will break easily and appear frizzy and dull. After the hair is dyed and ironed, the water content of the cuticles will decreas...

Problems solved by technology

Moreover, the introduction of siloxane will make the system must introduce a silicone oil emulsification system, making it difficult for the shampoo to be transparent

Chinese patent document CN107126378A discloses "a surfactant composition and the use of a cleaning agent made thereof", in which an anionic water-based polyurethane is mainly used, which has a setting effect, but cannot achieve plump and smooth effects

[0005] CN102020774A discloses a moisture-permeable and waterproof PU water-based resin for fabric coating. It is mentioned that the use of sulfonate can greatly improve the hydrophilicity of PUD to obtain a good water-containing moisturizing effect. One application is that it can be used for cosmetics, In personal care products such as shampoo; however, the water absorption and moisturizing effect of the PUD mentioned in the patent document cannot provide a fullness effect in the shampoo, and the hair volume is reduced by the water absorption and moisturizing effect
