Description

Hair Cosmetic Composition Comprising Mannan as Active Ingredient

The present invention relates to a hair cosmetic composition containing mannan as a natural scrub.

Although hair is not directly related to life, it has functions of protecting the body, keeping warm and tactile, acting as a cushion against friction from the outside, protecting hair from direct sunlight, cold and heat. Play a role.

       In addition, eyebrows, eyelashes, nose hairs and ear hairs have a protective function against invasion of sweat, dust and insects. Hair not only protects the head, but also has the function of absorbing heavy metals such as mercury, arsenic and lead that are not needed by the body and discharging them out of the body.

       In addition, hair plays an important role in showing male and female characteristics in terms of decoration. Even the same person can change their hairstyle and hair color, giving them another impression. Thus, hair plays a decorative role as well as to protect the head.

       Hair is a thin, thin protein structure with an average thickness of about 0.07 mm, which can be roughly divided into a hair shaft extending out of the skin and a hair root inside the skin. The scalp has a basic structure and physiological function similar to that of the skin, and the hair follicles of the scalp are more complex and more sebaceous than other areas. Root part is the part inside the hair follicle, buried in the scalp, about 2-4 mm deep. The bottom part of the hair root is swollen like a bead. This part is called a hair bulb, and the size of the hair determines the thickness of the hair. If you look at the cross section of the hair, it is divided into three parts: the innermost and the central part, the medulla, the cortex surrounding the medulla, and the outermost cuticle. The cuticle covers the surface of the hair and has a strong chemical resistance covering the inside of the hair, and is composed of three layers called epicuticle, exocuticle and endocuticle from the outside. Cortex is located inside the cuticle and accounts for most of hair (85-90%). Its main component is keratin protein, which is composed of cortical cells and intercellular binding materials, and is hydrophilic and easily affected by perm and dyeing. . The medulla is located in the center of the hair, has some melanin pigment particles, and there is a lot of fear in the medulla, which contains air.

      In general, among the cosmetics associated with such hair, shampoo is used to clean the hair soiled by sebum secreted from the dust or scalp in the air, which will be described in detail as follows.

      The shampoo is composed of water, a surfactant, a conditioning agent, a moisturizing agent, and the like to clean the hair soiled by dust or sebum with proper cleaning power and air bubbles, and provide effects such as gloss and flexibility to the hair.
