Polyurethane raw material special for cosmetic powder puff

Abstract

The invention discloses a polyurethane raw material special for a cosmetic powder puff. The polyurethane raw material special for the cosmetic powder puff comprises a polyurethane prepolymer and a curing agent. Meanwhile, the invention further provides a special production process for producing the cosmetic powder puff by using the polyurethane raw material. According to the polyurethane raw material special for the cosmetic powder puff, the traditional foaming mode of directly using isocyanate is adjusted into the mode of using prepolymer foaming, a mode of using water as a main component ofthe curing agent, and foaming is conducted in a mode of adding fillers, so that no friendliness of latex serving as a raw material is overcome, a mode for producing hydrophilic makeup cotton by takingthe polyurethane as the raw material is created, and the makeup cotton is hydrophilic and skin-friendly in hand feeling; furthermore, a brand new foaming process is used for the special raw material,the common foaming machine can be used for rapidly foaming, and the demolding time can be shortened to 2 to 3 minutes, so that the foam hole structure is more exquisite, and the product has skin-friendly hand feeling, is flexible and rebounded rapidly and meets the requirements of female consumers. The polyurethane raw material special for the cosmetic powder puff has the following characteristics: the product has high water-absorbing rate; the strength and the resilience maintaining rate are high after the product is wetted.

Description

technical field [0001] The invention relates to the field of chemistry, in particular to a special polyurethane raw material for cosmetic powder puffs. Background technique [0002] Powder puff is a kind of makeup tool. Generally, powder puffs and compact powder boxes will contain powder puffs, which are mostly made of cotton and velvet materials, and are used to pick up foundation and modify makeup.

AI Technical Summary

Problems solved by technology

The traditional polyurethane sponge is mainly made of polypropylene oxide, which is a kind of hydrophobic polyurethane, which cannot achieve a hydrophilic and skin-friendly texture.

Therefore, it cannot be recognized by female consumers.

[0004] At present, there is no polyurethane raw material for makeup puffs that can overcome the unfriendliness of latex raw materials and is hydrophilic and skin-friendly.
