Description

Plant shampoo and preparation method thereof

Technical Field

The invention belongs to the field of daily cosmetics, and particularly relates to a plant shampoo and a preparation method thereof.

Background

Due to the reasons of fast pace of life, high working pressure, environmental factors and the like, more and more people have the problems of dry and frigidity of hair, dandruff increase, scalp itching and even alopecia. Besides the function of cleaning hair, the hair washing product focuses more on the aspects of hair care, hair care and the like, for example, the hair is blackened and smooth, and the health state of hair is kept; by controlling and moisturizing oil, the water-oil balance of the scalp and the hair is maintained, and dandruff is prevented from being generated; can supplement nutrients to hair roots in time to prevent alopecia.

In addition, if the scalp is excessively greasy and dandruff, a large amount of microorganisms such as malassezia and propionibacterium are bred, hair follicles of the scalp are injured or blocked, the problem that the scalp and the hair are unhealthy is further aggravated, and a vicious circle is formed. Therefore, it is very important to develop a shampoo product with a natural plant formula, which can effectively improve the micro-environmental health of hair and scalp and inhibit the growth of harmful microorganisms.

Tea tree oil, also known as melaleuca alternifolia oil, is extracted from leaves and twigs of melaleuca alternifolia of Myrtaceae by steam distillation, is a colorless to pale yellow oily liquid, and has pleasant fragrance. The tea tree oil has good broad-spectrum bactericidal, antibacterial and health-care effects, is also an excellent preservative, and contains terpene which can penetrate deeper into scalp to repair damaged scalp matrix, so that the hair is moisturized and moistened, and dandruff generated by scalp dryness caused by transitional degreasing is improved.

Zinc pyrithione is a heterocyclic compound, is used as a transport inhibitor of fungal cell membranes, can cause depolarization of the membranes to kill fungi, can wrap the fungi after dissolution so as to inhibit the growth of the fungi, and also has the effect of inhibiting epidermal proliferation. Currently, anionic surfactants are used to solubilize and stabilize pyridinium zinc, but the effect is not ideal and even concentrations above 30% of the surfactant used can be harmful to the scalp.

Biosurfactants are surface active compounds released by microorganisms and have many advantages over chemical surfactants, such as lower toxicity, higher biodegradability, better environmental compatibility, higher foaming, high selectivity and specific activity at extremes of pH, temperature and salinity. The present invention provides a bio-amphoteric surfactant, corn steep liquor extract, which has the same characteristics as chemically synthesized surfactants, but has higher biocompatibility and lower toxicity.

The soapberry, also called as the delavay soapberry, contains more than ten amino acids such as saponin, protein, fat, arginine, histidine, glycine and the like in the peel, and also contains organic acid, phenolic acid and the like. The soapberry peel extract is used in shampoo products, not only makes hair smooth and bright, but also removes dandruff and alleviates the problem of alopecia by controlling oil, dredging and adjusting grease balance, and is suitable for various hair qualities.

The milk extract is added, so that the surface tension of the emulsion can be reduced, and the adsorption of the zinc pyrithione on the surface of the emulsion is promoted; a large amount of amino acids and proteins contained in the soapberry peel extract have charges, so that the charge content in the emulsion is increased, and the stability of the emulsion is improved; the invention uses the two with amphoteric biosurfactant in the corn steep liquor extract, can generate synergistic effect, further increases the charge quantity in the emulsion, reduces the grain diameter of the emulsion, improves the dispersion stability of the emulsion, promotes the dissolution of pyridinium zinc and increases the content of zinc pyrithione in the emulsion.

The cow milk extract and the soapberry peel extract are compounded, the interaction between the two different active substances can form a more complex mixture in the emulsion compared with a single substance, and the substance can promote the surfactant adsorption film in the emulsion to be firm, so that the difficulty of the gas molecules in the bubble film breaking through the liquid film to escape is increased, and the emulsion has obvious foam stabilizing and increasing effects when used in shampoo.

A preparation method of the plant shampoo comprises the following steps:

(1) adding water into a reaction kettle, heating to 75-85 ℃, then adding N-lauroyl sarcosine sodium and coconut monoethanolamide, and stirring at the rotation speed of 800-1200rpm for 15-25min to obtain a mixed solution;

(2) and when the temperature of the mixed solution is reduced to 40-50 ℃, adding the zinc pyrithione emulsion, stirring at the rotation speed of 1200-1800rpm for 8-15min, sequentially adding the sodium hyaluronate, the guar gum hydroxypropyl trimethyl ammonium chloride, the methyl glucose dioleate, the citric acid, the potassium sorbate and the plant extract, and continuously stirring for 20-40min to obtain the plant shampoo.

The invention has the beneficial effects that: the plant shampoo has good effects of removing dandruff and relieving itching, and is mild and non-irritant. The plant shampoo provided by the invention adopts plant extract prepared from natural plants as a raw material, and has good hair care and nourishing functions.
