Description

Hair moisturizing composition containing prinsepia utilis royle oil and preparation method and application thereof

Technical Field

The invention belongs to the field of cosmetics, and relates to a hair moisturizing composition containing prinsepia utilis royle oil as well as a preparation method and application thereof.

Background

Hair damage can be caused to different degrees by daily combing friction, chemical treatment, high-temperature styling, ultraviolet ray damage, air pollution and the like. Hair damage is classified into mild damage, moderate damage, and severe damage according to the degree of damage. For different damaged hair qualities, the phenomena of reduced water content of hair, reduced elasticity and toughness of hair, dryness, frightening hair, easy breakage and the like can occur. Since hair has no self-repairing ability, it is difficult to repair itself once it is damaged from the outside. The scalp serves as the "soil" for hair growth, and the quality and nutritional status of the scalp directly determine the hair quality. Therefore, in the daily moisturizing care of hair, not only basic moisturizing of hair dryness but also maintenance and moisturizing of scalp should be performed.

First, the hair shaft consists of hair follicles (scales), cortex and medulla from outside to inside. The integrity of the fur coat structure determines the apparent character of the hair. The outermost layer of the fur coat is attached with a layer of nonpolar lipid, whose main component is C16-22 alkane, which becomes lipid layer A and determines the glossiness of hair. The inner layer of the fur coat also contains about 25% of structural lipids, a Cell Membrane Complex (CMC), whose main components are ceramides, cholesterol sulfate, cholesterol, fatty alcohols and free fatty acids. The CMC lipid is combined with protein to form lipoprotein, and a continuous network structure is formed around hair fiber, so that the CMC lipid has an intercellular adhesion effect, and the integrity and the tensile strength of the hair stem fiber are maintained. Thus, achieving a basic moisturization of the hair dryness can be achieved by supplementing the hair with fatty acids in the CMC. Secondly, the scalp also has a barrier as a specific area of skin composition. The scalp barrier is formed by the combination of the stratum corneum cells and the "brick wall structure" composed of "lipids" (mainly composed of ceramide, cholesterol and free fatty acid) and "natural moisturizing factor" (NMF) between the cells, and the "sebum membrane" attached to the surface of the scalp barrier. Wherein the "sebaceous membrane" is a layer of aqueous membrane covering the skin surface, is the outermost layer of the skin barrier, is formed by emulsifying "sebum" secreted by sebaceous glands, "lipid" produced by the disintegration of cells of the stratum corneum, and "sweat" secreted by sweat glands, and has weak acidity. The main components of the health-care product are ceramide, squalene, linoleic acid, linolenic acid and lipid, and the health-care product has the functions of locking water and resisting inflammation. When the scalp barrier changes, the scalp permeability is increased, the moisture loss is serious, and the scalp structure is damaged. The basic moisture retention of the scalp can be realized by supplementing essential fatty acids such as linoleic acid and linolenic acid to the scalp.

Based on the above analysis, dual moisturization of the hair and scalp can be achieved by supplementing the hair and scalp with the fatty acids required for them. Wherein, linoleic acid and linolenic acid required by the scalp belong to polyunsaturated fatty acid, and mainly act on the sebum layer to improve the scalp quality and maintain the scalp barrier function. While the hair-specific fatty acids are predominantly monounsaturated fatty acids. The monounsaturated fatty acid has a medium linear molecular structure and strong polarity, has strong adsorption capacity with polar keratin in hair fibers, can effectively permeate into a CMC layer of the fur cuticle, and can realize deep repair of hair shafts.

CN104510668A discloses a moisturizing composition, a preparation method and an application thereof, wherein the moisturizing composition comprises moisturizing active ingredients, the moisturizing active ingredients at least comprise prinsepia utilis royle oil and prinsepia utilis royle polysaccharide, and the weight ratio of the prinsepia utilis royle oil to the prinsepia utilis royle polysaccharide is 0.5-10. The moisturizing composition has good moisturizing effect, and is suitable for application in cosmetics, health products and medicines, especially in cosmetics.

CN108998301A discloses a milk soap for seborrheic alopecia and a preparation method thereof, wherein the milk soap for seborrheic alopecia comprises the following raw materials in parts by weight: 80-100 parts of olive oil, 10-20 parts of coconut oil, 15-25 parts of sodium hydroxide, 40-60 parts of deionized water, 10-30 parts of aloe gel, 5-10 parts of defatted goat milk, 3-5 parts of liquorice, 1-3 parts of radix stemonae, 1-2 parts of ginger, 3-5 parts of polygonum multiflorum, 3-5 parts of euphorbia tenuifolia inflorescence, 1-2 parts of salvia miltiorrhiza, 1-2 parts of pseudo-ginseng and 1-3 parts of compound essential oil. The milk soap prepared by the method has the effects of balancing scalp grease, cleaning hair and scalp, relieving cranial nerves, promoting cell regeneration, preventing alopecia and promoting hair growth under the combined action of various raw materials.
