Description

Tattooing paste

Technical Field

The invention relates to the technical field of tattooing patches, in particular to tattooing liquid, a preparation method thereof and a tattooing patch.

Background

Tattoos have been a part of human culture for thousands of years, and tattooing development has become a fashionable and popular noun to date, and is deeply favored by young people in the society of today. The traditional tattooing method generally adopts the technology that a needle is used for puncturing the skin and then pigment is applied to a wound to enable the body to have permanent patterns, but the traditional tattooing can bring fashion and beauty but also bring pain and even diseases. Therefore, in recent years, non-permanent tattoo products are increasingly favored by young people because of the characteristics of simplicity, convenience, no wound, no pain, quick pattern replacement, and the like.

The existing non-permanent tattoo product on the market mainly takes genipin as a tattoo paste of a main colorant, and the tattoo paste slowly reacts with skin through the genipin to finally form a corresponding blue tattoo pattern on the surface of the skin, so that the tattoo pattern has strong sense of reality and is very similar to the effect of the traditional tattoo. However, the existing genipin plain weave body paste has the problems that the maintenance time is generally 3-5 days and the existing genipin plain weave body paste is not resistant to washing, so that the use experience of consumers is greatly reduced.
