The present invention relates to a pigment composition, a colored hydrogel composition, a colored hydrogel sheet and a method for producing a colored hydrogel composition.

A hydrogel is a material having a three-dimensional hydrophilic polymer network structure using purified water as a dispersion medium and capable of absorbing a large amount of water and has the same flexibility as a natural tissue. Due to these characteristics, application fields such as wound dressings, contact lenses, medicines or cosmetic delivery media, implants, wastewater treatment agents and the like have been diversified.

In addition, hydrogels have the advantage of being able to add new functions such as controlled release, which can control the delivery of the substances contained therein, and pH, temperature, electric field, and irritation that is stimulated by light, have.

Hydrogels with these properties have a structure similar to that of the human body and are widely used in various pharmaceutical industries as well as cosmetics and medical care since they have inert biocompatibility, elasticity like rubber, and excellent permeability of oxygen and nutrients .

In recent years, a mask pack has been developed which is improved in moisturizing, nutritional supply or exfoliation effect by utilizing elasticity, skin adhesion, and soft touch of such hydrogel.

On the other hand, the naphthoquinone dye combines with keratin, which is the main component of hair, to form a color film outside the hair, thereby protecting the hair damaged by dyeing or perming. In particular, it gives a bright color when used in a hair dye . It is also characterized by its ability to bind to human proteins, resulting in fewer genetic damage to the human body and its ability to be used in tattoos and cosmetics.

A tropical shrub called Lawsonia inermis and a naphthoquinone pigment, which is present in the leaves of the tree, are generally powder products made by drying the leaf.
