Problems solved by technology

However, the current water-based nail polish is not mature enough, and there are still some defects, such as poor gloss, poor water resistance, poor adhesion, and the surface of the nail polish will stick back after drying, etc., which cannot meet the needs of consumers.
[0005] Chinese patent CN101697943A discloses a method for preparing environmentally friendly water-based nail polish. This water-based nail polish is a common method for preparing water-based nail polish at present, but the resin in its formula still contains nitrocellulose, which cannot be truly water-based, environmentally friendly, and non-toxic. The gloss of the obtained water-based nail polish product is low; Chinese patent CN102228411B discloses a two-in-one water-soluble nail polish solution, and its patented formula solves the problems of water-based nail polish drying speed, heat resistance and cold resistance, etc., but its formula The hardening agent added is polyurea resin. Compared with aldehyde and ketone resin, polyurea resin has poor compatibility, and it is easy to cause instability such as flocculation with colorants, resins and other formulation substances in the nail polish formulation, resulting in The scope of application is small, and film-forming aids need to be added in this patent, and it cannot be truly solvent-free and environmentally friendly
[0006] Although water-based nail polish is the development trend of nail polish products in the future, there are still few related researches on it. We urgently need to develop a water-based nail polish product with fast drying, high gloss, good adhesion, and high fullness, so as to meet market development needs

Abstract

The invention discloses a waterborne nail polish based on an aqueous polyurethane dispersion. The waterborne nail polish takes an aqueous polyurethane dispersion as the main ingredient, is mixed with a brightening agent, a hardening agent, a thickening agent, an adhesion promoter and the like, dispenses with a film-forming additive, cannot injure nails, is very mild for human bodies, and really embodies the green, environment-friendly, nontoxic and tasteless performance. The waterborne nail polish has the properties of relatively good adhesion, relatively high hardness, relatively short surface dry time, excellent gloss and fullness, soft hand feeling and the like. Meanwhile, the selected thickening agent enables the formula product to have very excellent stability, and effectively prevents pearl powder, color paste and the like from settlement.

Description

technical field [0001] The invention relates to a water-based nail polish, in particular to a water-based nail polish based on a water-based polyurethane dispersion. Background technique [0002] Nail polish belongs to a large category of products in the color cosmetic series, which has the function of beautifying and modifying nails. At present, the nail polishes used by people are divided into traditional solvent-based nail polishes and emerging water-based nail polishes. [0003] Traditional solvent-based nail polish contains a lot of irritating chemical ingredients, such as acetone, toluene, etc. These are harmful substances, which can easily make nails dry, yellow, and brittle, affecting human health and causing environmental pollution. The principle of solvent-based nail polish adhering to the nail surface is to destroy the nail surface first, creating many rough holes on the surface, and the nail polish penetrates into the pits. If used for a long time, the pigment i...
