Description

Pricklyash seed hair sun-screening agent and preparation method thereof

Technical Field

The invention belongs to the technical field of cosmetics, and particularly relates to a pricklyash seed hair sunscreen agent developed aiming at the problem that hair after hair dyeing is easy to decompose and fade, particularly under illumination, and a preparation method thereof.

Background

The hair dyeing product is necessary for many people in daily life, but chemical reactions in the hair dyeing process can change the surface and internal structures of the hair, so that the hair is warped, the hair is detackified, and when the hair surface is rough, light scattering is caused, so that the hair loses luster; the loss of protein and the reduction of crystallinity of the hair lead to the reduction of water retention capacity, the reduction of tensile strength, the reduction of elasticity and toughness and other physical property changes; meanwhile, damaged hair loses the protective structure of the outer layer, and hollowing also occurs inside the damaged hair, so that the pigment is difficult to effectively retain in the hair. If the hair just dyed is irradiated by ultraviolet rays for a long time, the hair dyed is not only more fragile, but also is not favorable for maintaining hair color.

The research finds that: proteins in hair are susceptible to photochemical degradation, and ultraviolet rays also accelerate oxidation of amino acids and carbon between polypeptide chains, because ultraviolet rays can generate a large amount of active oxygen radicals by photo-degrading amino acids and reacting with photosensitive substances, thereby causing alteration of hair fibers. Free radicals, mediated by water or atmospheric moisture, undergo a series of reactions that cause significant damage to hair proteins, especially keratin, and lead to degradation of melanin, causing the hair to change color. In addition, the visible light in sunlight causes more damage to the lipid layer than ultraviolet light, and the lipid layer of hair is easily damaged by lipid peroxide generated by illumination, so that the integrity, the hydrophobicity and the hardness of hair shafts of the hair are obviously and negatively influenced.

At present, although a lot of sunscreen products are available on the market, most of the sunscreen products are mainly used for skin. The physical sun-proof skin product is based on the principle of light reflection, is more greasy and heavy, and can only play a role after being coated to a certain thickness, for example, when the physical sun-proof skin product is used for sun-proof hair, the hair looks greasy and thin, the hairstyle is difficult to maintain, the appearance is influenced, and discomfort is brought to a user; under the action of bacteria, ultraviolet rays and the like, grease is deteriorated to block hair follicles, and a scalp health system is damaged, so that symptoms such as dandruff, scalp itching, alopecia and the like are caused; the chemical sunscreen skin product absorbs ultraviolet rays in sunlight by utilizing chemical reaction, and has more chemical sunscreen additives, so that the chemical sunscreen skin product has great harm to hair and scalp after long-term use; and melanin in the hair reacts with part of the chemical sunscreen additive, resulting in fading of the dyed color.

In view of the above, there is no hair sunscreen product that solves the problem of fading of hair color, especially after hair is dyed, and therefore, there is a need to develop a new hair sunscreen product that is at least partially free from the above-mentioned problems of the prior art.
