Description

Hair conditioner with scalp care and hair nourishing effects and preparation method thereof

Technical Field

The invention belongs to the technical field of daily chemical products, and particularly relates to a hair conditioner with scalp care and hair nourishing effects and a preparation method thereof.

Background

The condition of a person's hair often reflects much information about the person, such as health status, mental state, mood, lifestyle habits, etc., so people are also increasingly paying more attention to the hair care of the person. The hair care comprises scalp care and hair nourishing, and the hair care products which can realize the two effects are usually independent at present, for example, essential oil for scalp, hair conditioner and hair film for hair, and two procedures are designed during operation, which is troublesome.

Active ingredients in the existing scalp care products are mainly traditional Chinese medicine plant extracts, plant essential oil, protein amino acid, organic skin penetrating agent, grease, surfactant with a cleaning effect and the like. However, most of the organic components are macromolecular substances, and the proportion of the organic components which can be actually absorbed by skin cells is not well determined.

CN112022749A discloses a hair conditioning composition with function of enhancing scalp barrier, its preparation method and application, which is composed of the following raw materials by weight percentage: 5-20% of phytosterol ester, 50-80% of trimethylolpropane triester, 5-20% of B vitamins, 1-20% of natural vegetable oil and 1-15% of water-soluble grease. The composition can be used for preparing shampoo, hair conditioner, hair treatment cream or hair membrane, has effects of moistening scalp, enhancing scalp barrier, nourishing hair follicle, and ensuring smoothness and refreshing scalp. However, the scalp care ingredients in the invention are phytosterol ester, trimethylolpropane triester, B vitamins, natural vegetable oil and water-soluble oil, which are all organic matters, and the problem that the scalp care ingredients are large in molecular particle size and difficult to absorb is possibly existed.

CN113476354A discloses a hair loss preventing and hair growing hair conditioner, which comprises the following components in percentage by mass: 1-6% of thickening agent, 1-2% of cationic surfactant, 1-10% of proline, 0.1-0.5% of cacumen biotae extract, 0.1-0.5% of ginseng extract, 0.1-1% of ginger extract, 0.1-1% of cordyceps militaris extract, 0.1-1% of astragalus membranaceus root extract, 0.1-2% of saccharide isomer and the balance of water. The hair conditioner can maintain scalp environment steady state, activate proliferation and differentiation of hair growth cells, repair hair follicle structure, rebuild skin barrier, effectively strengthen and nourish hair, and nourish hair. However, although the plant extracts are common raw materials of daily chemical varieties, the components of each extract are very complex, and the stability of the components of each batch of samples cannot be ensured in practical application.

Therefore, it is very significant to develop a hair care product which is easily absorbed by the scalp, has safe ingredients, and has the effects of caring the scalp and nourishing hair.
