Description

Technical Field

[0001] The invention relates to the technical field of shampoo preparation, in particular to a shampoo added with a selenium-containing plant extract and a preparation process thereof. Background Art

[0002] Shampoo, also known as shampoo, is the most widely used hair care product and one of the most commonly used hair cosmetics. It is used to clean the oil secreted by the human body, sweat, cells shed from the scalp, foreign dust, microorganisms, residues of styling products and bad odors attached to the scalp and hair, keeping the scalp and hair clean and beautiful. Shampoo has various dosage forms, and the shampoos on the market are mainly liquid shampoos. Most liquid shampoos have the following structural components, among which surfactants, foam stabilizers, thickeners, preservatives and flavoring agents are basic ingredients. Other ingredients depend on consumer demand and cost-effectiveness.

[0003] There are many kinds of shampoos on the market with various added ingredients, but the effects are relatively simple and cannot effectively regulate the scalp and hair. Therefore, it is necessary to develop a shampoo with selenium-containing plant extracts. Summary of the invention

[0004] The present invention provides a shampoo added with selenium-containing plant extracts and a preparation process thereof, so as to solve the problem that the shampoo in the prior art has a poor scalp nourishing effect, and can adjust the water-oil balance, deeply nourish the scalp, promote scalp microcirculation, enhance the vitality of skin surface cells, and promote metabolism.

[0007] Preferably, a preparation process of a shampoo containing a selenium-containing plant extract comprises the following steps: A. Prepare selenium-enriched berry tea extract for standby use; B. Add selenium-rich berry tea extract, linoleamidopropyl PG-dimethyl ammonium chloride phosphate, surfactant, urea capsule, sunflower seed oil, percarbamide, Nepal gold methyl ester, angelica extract, motherwort extract, and myrtle hydrosol into a mixing tank, heat and stir the mixture to obtain a mixed solution; C. Add an appropriate amount of deionized water to the mixed liquid in the mixing tank, stir at a constant temperature, and then let it stand for a while to obtain shampoo.

[0008] Preferably, the preparation method of the selenium-rich berry tea extract in step A is as follows: selenium-rich berry tea powder is mixed with ethanol, and vacuum extraction is performed to obtain the selenium-rich berry tea extract; the vacuum extraction temperature is 35-40°C, and the time is 30-90 min.

[0009] Preferably, in step B, the heating temperature is 55° C.-65° C., the stirring rate is 1200-2000 rpm, and the time is 70 min-100 min.

[0010] Preferably, in step C, the constant temperature stirring temperature is 55° C., and the stirring time is 20 min-30 min.

[0011] Preferably, the standing time in step C is 2h-4h.

[0012] Preferably, a shampoo containing selenium-containing plant extract is added, and the shampoo is used in hair nourishing cosmetics. Beneficial Effects

[0013] (1) The preparation process of the present invention is simple, and the prepared shampoo can regulate the water-oil balance, deeply nourish the scalp, promote scalp microcirculation, enhance the vitality of skin surface cells, and promote metabolism.

[0014] (2) The selenium-rich berry tea extract added in the present invention has a strong antioxidant effect, can remove free radicals in the body, slow down the aging rate of scalp cells, and tea polyphenols and selenium can dilate blood vessels and promote blood circulation; the added linoleamidopropyl PG-dimethylammonium chloride phosphate effectively reduces the occurrence of itching, soothes the scalp while cleaning the scalp, and further inhibits the production of scalp oil; the added urea capsule has a hydrophilic effect, can soften the stratum corneum protein, and can be combined with sunflower seed oil to further improve the repair and supplement of sebum. Moreover, after softening the stratum corneum protein, it is more conducive to the diffusion and penetration of myrtle hydrosol, improves the promotion of cell proliferation, and plays a role in nourishing the scalp; the added percarbamide promotes skin blood circulation, increases skin nutrition, and regulates the water-oil balance of the skin; the added Nepalese gold methyl ester can treat neuralgia, skin itching, rash and eczema symptoms. The present invention adopts the synergistic effect of multiple effective ingredients, which can prevent and treat hair loss, improve hair quality, inhibit dandruff regeneration, and refresh the mind.
