Problems solved by technology

In the emulsification system, the liquid crystal emulsifier increases the probability of forming a liquid crystal structure, but each liquid crystal emulsifier has its use restrictions, which does not mean that a liquid crystal structure can be formed in any system, and is still subject to the formula composition and Manufacturing Process Limitations
At the same time, the current liquid crystal emulsifiers generally have insufficient emulsification effect and cannot be used alone as the main emulsifier; they must be used in conjunction with other main emulsifiers, but this will increase uncertainties and may affect the formation of liquid crystal structures

Embodiment 1

[0039] 50 parts by mass of stearyl phosphate (commercially available product, containing 40 parts by mass of stearyl phosphate monoester, 8.75 parts by mass of stearyl phosphate diester, 1.25 parts by mass of free phosphoric acid), 20 parts by mass of C 16 Add fatty alcohol (cetyl alcohol) and 30 parts by mass of ceteareth-2 into the reaction kettle, heat up to 85°C and melt, then depressurize to -0.1MPa, homogenize at 3000r / min for 5min, and keep warm at 85°C for 1h , and then add 0.05 parts by mass of 2,6-di-tert-butyl-4-methylphenol (BHT). Then the temperature is lowered and the material is discharged to obtain the liquid crystal emulsifier composition I.

Embodiment 2

[0041] 60 parts by mass of eicosyl phosphate (commercially available product, containing 52.5 parts by mass of eicosyl phosphate monoester, 6.0 parts by mass of eicosyl phosphate diester, 1.5 parts by mass of free phosphoric acid), 30 parts by mass of C 18 Add fatty alcohol (stearyl alcohol) and 10 parts by mass of ceteareth-4 into the reaction kettle, heat up to 95°C and melt, then depressurize to -0.05MPa, homogenize at 4500r / min for 5min, and keep warm at 95°C for 1h , then add 0.05 parts by mass of vitamin E acetate. Then the temperature is lowered and the material is discharged to obtain the liquid crystal emulsifier composition II.

Embodiment 3

[0043] 55 parts by mass of behenyl phosphate (commercially available product, containing 46.75 parts by mass of behenyl phosphate monoester, 7.15 parts by mass of behenyl phosphate diester, 1.10 parts by mass of free phosphoric acid), 25 parts by mass of C 20 Add fatty alcohol (eicosanol) and 20 parts by mass of ceteareth-6 into the reaction kettle, heat up to 90°C and melt, then depressurize to -0.08MPa, homogenize at 5000r / min for 5min, and keep at 90°C for 1h , and then add 0.05 parts by mass of dibutylhydroxytoluene. Then the temperature was lowered and the material was discharged to obtain the liquid crystal emulsifier composition III.

Abstract

The invention discloses a liquid crystal emulsifier composition, and a preparation method and application thereof in cosmetics. The liquid crystal emulsifier composition provided by the invention comprises the following components in parts by weight: 50-60 parts of high-carbon fatty alcohol phosphate, 20-30 parts of high-carbon fatty alcohol, 10-30 parts of ceteareth, and 0.05 parts of antioxidant. The liquid crystal emulsifier composition can easily form a liquid crystal structure in emulsion; the requirements of a preparation process can be reduced; the liquid crystal emulsifier composition has a good emulsification effect on commonly used fats, silicon oils, vegetable greases and synthetic greases when the liquid crystal emulsifier composition is used as a main emulsifier. The cosmetics prepared by using the liquid crystal emulsifier composition have good wettability and can ensure fine and silky skin-touch.

Description

technical field [0001] The invention relates to a composition, in particular to a liquid crystal emulsifier composition, a preparation method and its application in cosmetics, belonging to the field of daily chemicals. Background technique [0002] Liquid crystals (also known as mesophases) generally refer to structures whose order states lie between isotropic liquids and ordinary crystals, with structural short-range disorder and long-range order , usually composed of "rod-like" or "disk-like" molecular orderly arrangement, it has both liquid-like fluidity and crystal-like anisotropy. Liquid crystals can be divided into thermotropic (thermotropic) liquid crystals and lyotropic (lyotropic) liquid crystals: the former generally only exists in pure substances within a certain temperature range, and may also appear in mixtures; while the latter refers to range, consisting of compounds and solvents. [0003] Surfactant liquid crystals are generally lyotropic liquid crystals, a...
