Anhydrous scalp repair base liquid and preparation method thereof

Abstract

The invention relates to an anhydrous scalp repair base solution and a preparation method thereof. Three leading-edge skin care concepts of'micro-ecological management ', 'barrier repair' and'cell defense 'are systematically integrated in the scalp care field for the first time, the three systems cooperate with one another to jointly construct a complete scalp health management closed loop, and the limitation of a single technical path is solved. Micro-ecology is managed in an intelligent adjusting mode, and barrier repair is combined, so that the health basis of scalp is fundamentally improved, and the recurrence rate of problems is effectively reduced. Wherein anti-light aging and anti-pollution components such as phytosterol, cholesterol, cymene-5-ol, inulin, hydrated silica and the like which are verified in skin care products are introduced, active intervention on scalp aging factors is realized in wash-off products for the first time, anhydrous formula design is matched with a simple mixing preparation process, the activity of functional components is ensured, and the skin care product has good skin care effect. The market requirements are effectively met.

Description

Technical Field

[0001] This invention relates to the field of daily chemical products technology, specifically to an anhydrous scalp repair base liquid and its preparation method. Background Technology

[0002] Most scalp care products currently on the market have limited functions and the following limitations:

[0003] 1. Treating the symptoms but not the root cause: Most anti-dandruff and anti-itch products rely on traditional antibacterial agents (such as ZPT and ketoconazole), which work by powerfully killing microorganisms. However, long-term use can easily disrupt the scalp's microecological balance, leading to recurring problems and failing to repair the damaged scalp barrier.

[0004] 2. Lack of anti-aging dimension: Existing products mainly focus on solving immediate symptoms (such as dandruff and oiliness) and have not yet established "scalp anti-aging" as a clear care dimension. Like facial skin, the scalp is subject to oxidative stress and cell damage caused by environmental factors such as ultraviolet rays, blue light, and pollution, which accelerates aging, manifesting as decreased hair follicle vitality, thinning of the scalp, and reduced elasticity. However, the market currently lacks targeted preventative care products.

[0005] Therefore, there is an urgent need in this field for a comprehensive solution that can regulate scalp health from the root, while also possessing anti-aging functions and a superior user experience. Summary of the Invention

[0006] In view of the problems existing in the prior art, the present invention discloses an anhydrous scalp repair base liquid, the main components and weight ratio of which are: cymene-5-ol 0.1%-0.5%, 1,2-pentanediol 2%-5%, inulin 1%-2%, ceramide NP 0.1%-0.5%, phytosterol 0.5%-2%, cholesterol 0.1%-0.5%, decyl glucoside 8%-12%, sodium cocoyl hydroxyethyl sulfonate 5%-10%, bis-PEG-18 methyl ether dimethylsilane 2.5%-3.5%, hydrated silica 0.7%-1.2%, and the balance being caprylic / capric triglycerides.

[0007] The composition includes a microecological regulation system consisting of cymene-5-ol, 1,2-pentanediol, and inulin. This compound precisely inhibits harmful bacteria such as Malassezia and supports beneficial bacteria native to the scalp through prebiotic action, thus rebuilding a healthy scalp microenvironment.

[0008] It features a biomimetic barrier repair system composed of ceramide NP, phytosterols, and cholesterol. This lipid complex, in a ratio close to that of human sebum, directly replenishes intercellular lipids in the scalp, rapidly repairing the physical barrier.

[0009] Using caprylic / capric triglycerides as a solvent, an anhydrous oily base is formed, which on the one hand ensures the stability of the above-mentioned active ingredients, and on the other hand serves as a pre-cleansing oil to effectively dissolve excess oil and keratin plugs on the scalp.

[0010] It contains a gentle cleansing system composed of decyl glucoside and sodium cocoyl hydroxyethyl sulfonate, which provides gentle and effective cleansing power without irritating sensitive scalps.

[0011] A method for preparing an anhydrous scalp repair base solution includes the following steps: Step 1: Select caprylic / capric triglyceride, ceramide NP, phytosterol, cholesterol, cymene-5-ol, and bis-PEG-18 methyl ether dimethylsilane by weight ratio, mix them, heat and stir to dissolve and mix them evenly to obtain a mixed oil. Step 2: After the mixed oil has cooled down, add 1,2-pentanediol, inulin, decyl glucoside, sodium cocoyl hydroxyethyl sulfonate, and hydrated silica according to the weight ratio. After homogenization, the waterless scalp repair base solution is obtained.

[0012] The beneficial effects of this invention: This invention is the first to systematically integrate three cutting-edge skin care concepts—"microecological management," "barrier repair," and "cellular defense"—into the field of scalp care. These three systems work synergistically to construct a complete closed loop for scalp health management, overcoming the limitations of single-technology approaches. By intelligently regulating the microecology and combining it with barrier repair, it fundamentally improves the health foundation of the scalp, effectively reducing the recurrence rate of problems. It incorporates plant sterols, cholesterol, cymene-5-ol, inulin, and hydrated silica—ingredients proven in skincare products for their anti-photoaging and anti-pollution properties. For the first time, it achieves proactive intervention in scalp aging factors in a wash-off product. The anhydrous formula design, combined with a simple mixing and preparation process, ensures the activity of the active ingredients, effectively meeting market demands. Detailed Implementation
