Benefits of technology

This patented product contains two different ingredients - one called C10-20 fatty acids chloroesterate (CFO) and another called lanosteroid hydroxypropylate monomethyl ether sulfone). These components are combined together at certain specific ratios that created an ideal mixture when applied topically during treatment. They have strong binding properties like water but don't stick too much greasy into our skins due to their unique molecular structures. By combining these ingredient compositions they provide effective treatments against various issues such as dryness, wrinkles, burnings, scars, etc., while also being gentle enough to protect sensitive areas from damage over time without adding any synthetic substances.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving or maintaining good hydronetic properties (moistenability) on the surface layer of the lips due to lack of oily substances from inside them caused by environmental factors like sunlight exposures overexposure to UV light, smoking cigarettes, excessive exercise, poor nutrient supply, alcohol consumption, high blood pressure levels, stress conditions, etc.). Additionally, these ingredients can cause damage through free radical reactions with unsaturated bonds present within fats called triglycerides found naturally throughout the body's cells.

Abstract

The invention discloses a lip-care composition and a preparation method thereof. The lip-care composition comprises effective components including, by weight, 50-80 parts of C10-30 acid cholesterol/lanosterol mixed ester, 1-40 parts of vegetable oil and 5-25 parts of wax. The preparation method of the lip-care composition includes steps: mixing, to be specific, heating and dissolving wax, adding vegetable oil, mixing, heating to 75-90DEG C, and keeping the temperature for at least 30min to obtain a premix; mixed ester adding, namely adding the C10-30 acid cholesterol/lanosterol mixed ester into the premix, and mixing to obtain the lip-care composition. Due to high content of the C10-30 acid cholesterol/lanosterol mixed ester, the chemical structure of the lip-care composition is similar tothat of skin sebum, high hydrophilicity is realized, a stratum corneum not sticky to human skin is formed on the skin, regulation of skin moisture content and skin barrier function can be realized, and a high value in dry skin care is achieved.
