Composition containing aqueous nonionic polyurethane dispersions and preparation method thereof

Abstract

The invention provides a composition containing aqueous nonionic polyurethane dispersions. The composition is prepared from, by weight, (a) 0.1-30 parts of aqueous nonionic polyurethane dispersions, (b) 10-30 parts of a dirt removing surface active agent, (c) 0.01-5 parts of a conditioner and (d) a water containing carrier, and all parts are added to reach 100. The composition is used as a hair washing agent, hair can be natural and tough, and the fluffy state lasting time of the hair can also be prolonged.

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.

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
