Strippable facial mask substrate based on waterborne polyurethane dispersoid

Abstract

The invention discloses a strippable facial mask substrate based on waterborne polyurethane dispersoid. The strippable facial mask substrate takes the waterborne polyurethane dispersoid as a main ingredient and is matched with a thickening agent, an emulsifying agent, grease, a preservative, essence and the like. During use, the skin is uniformly coated with the strippable facial mask substrate, the strippable facial mask substrate can be completely attached to facial skin to form a film, and the film is breathable and is not tight after formed; the facial mask substrate further has the efficacy of skin tightness; and during stripping, the substrate is wetted by water, a facial mask can be taken down like voile, tearing pain feeling is avoided, no residue is left, and perfect stripping is realized. The strippable facial mask substrate has good compatibility with active functional components, essence containing moisturizing ingredients, whitening ingredients, anti-aging ingredients and the like can be added to prepare facial masks with various effects, meanwhile, the strippable facial mask substrate can be applied to the fields of strippable hand masks, neck masks, leg masks, body masks and the like.

Description

technical field [0001] The invention relates to a facial mask matrix, in particular to a peelable facial mask matrix based on aqueous polyurethane dispersion.

AI Technical Summary

Problems solved by technology

The problem is that the shape of the face mask is fixed, and it cannot be completely fitted to everyone's face when used. The toughness and skin-adherence of the non-woven fabric in a wet state are not high. When the mask is used, the user's face must be kept Stand still, once there is a facial relaxation action, it will cause the mask to detach from the skin

The permeability of the face mask is not high, which cannot meet the high penetration and high absorption requirements of the beauty liquid in the mask; 2) The mud cream mask contains more kaolin in its ingredients, which is easy to cause allergies when used, and the mud cream is used during use. Clothes are easily stained, and it is difficult to clean them completely; 3) Tear-off mask, the main ingredients are polymers, water and alcohol, can be used to completely fit the face, tighten pores, and have the effect of exfoliating dead skin and oil. It has a tight feeling after drying, and it should be peeled off from top to bottom. It is not suitable for sensitive skin, and it will hurt when pulled

[0005] Chinese patents CN 102895164A and CN1883438A disclose facial masks containing polyurethane. Polyurethane plays a role in coagulating water. Polyurethane does not play the role of self-filming. Film field; Chinese patent CN 2462923Y discloses a preparation method of a hydrogel beauty skin care sticker, which uses a cured polyurethane plastic film as the supporting part of the facial mask. Membrane effect, need to use medical adhesive as the attachment layer, there is a defect of irritating the skin

Chinese patent CN103705428A discloses a kind of exfoliating cream containing a small amount of non-ionic polyurethane dispersion, which plays a kind of "rubbing mud" effect in polyurethane, and its short stay on the face cannot play the role of polyurethane peelable mask matrix The effect of time tightening pores
