Powder puff based on application of polyurethane (PU)

Abstract

The invention discloses a powder puff based on application of polyurethane (PU), which satisfies application in baking and catering industries. The powder puff comprises the following components by mass percent: 85-95% of PU and 5-15% of auxiliary preparations, wherein PU comprises the following components by mass percent: 65-75% of carbamate compound and 15-25% of reaction hardening agent; the auxiliary preparations comprise the following components by mass percent: 3-8% of foaming agent and 0.5-1.5% of catalyst. The powder puff provided by the invention has the beneficial effects that a preparation method is simple; the material requirements are low, so that the local materials are conveniently obtained and large-scale processing is satisfied; in the mixture preparation process, the oily components in the carbamate compound are effectively neutralized through auxiliary cooperation of the reaction hardening agent and the foaming agent and the oily feeling of the carbamate compound is eliminated by utilizing the peculiar aroma of the catalyst; the powder puff is scientific and reasonable in formula and does not have any side effect.

Description

technical field [0001] The invention relates to polymer application technology, in particular to a powder puff based on polyurethane application. 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. According to the different types of puffs, the main functions are as follows: the sponge puff is more suitable for wet water use, and it is convenient to spread the liquid foundation evenly; the triangular shape is convenient for applying the corners of the eyes and the wings of the nose. Wet and dry powder puffs are generally round or rectangular, and you can apply wet and dry powder puffs to your face no matter whether you use it wet or not. Regardless of whether you choose a sponge puff or a wet-dry puff, it is better to have moderate softness. Because the shape design of the pow...
