The present invention relates to a translucent or semi-translucent nano-emulsion cosmetic composition, having excellent stability, comprising high content oils (5 to 30%) and, more specifically, to a nano-emulsion cosmetic composition having a physical property of low viscosity (5000 cps or less) with a translucent or semi-translucent appearance by preparing pre-emulsion by applying an emulsifier and then secondly passing the pre-emulsion through a high pressure homogenizer, and a method for preparing the same.

The present invention relates to: an oil-in-water emulsion composition having a viscosity of 1,500-50,000 cps, and comprising an anionic surfactant and a sugar surfactant so as to satisfy the following relational expression 1; and a cosmetic composition containing the same. [Relational expression 1] 0.01≤A/B≤1 (In relational expression 1, A is the wt % of the anionic surfactant, and B is the wt % of the sugar surfactant, wherein the wt % of each ingredient is based on the total weight of the composition, and B is 1-30 wt %.)

Disclosed herein are compositions, comprising nanosized droplets, wherein the nanosized droplets comprise a cannabinoid oil, a dietically acceptable carrier oil, a surfactant, and water. Also disclosed herein are methods of making and using the same.

The invention relates to a method which includes the following steps: mixing hydrophilic components, including water and an emulsifying saponin which is less than 1% of the emulsion regardless of the proportion of the oily phase; mixing lipophilic components, including the oily active substance, which can reach 40% of the emulsion; a first homogenization of the two preceding phases using a rotor/stator or ultrasonic mixer until a mean diameter of less than 6 μm of the oily droplets is obtained; and a second homogenization of the preceding mixture using a high-pressure homogenizer until a mean diameter of less than 0.4 μm of the oily droplets is obtained.

The present invention relates to a method for the protection of human skin against visible light damages, namely blue light, said method comprising the step of applying a cosmetic composition containing an effective amount of vitamin B3 or a derivative thereof and an effective amount of vitamin B6 or derivative thereof to the skin.

The invention relates to a composition in the form of a nanoemulsion or microemulsion, comprising: at least two different fatty acid esters of (poly)glycerol a) and b); c) at least one polyol in a total content of greater than 15% by weight; d) at least one oil; e) water; and f) at least one anionic surfactant of formula (II)

##STR00001##

it being understood that said composition comprises at least one anionic surfactant of formula (II) when the first fatty acid ester of (poly)glycerol is a polyglyceryl laurate comprising from 3 to 6 glycerol units and the second fatty acid ester of (poly)glycerol is a (poly)glyceryl laurate comprising from 1 to 3 glycerol units.

The invention also relates to a cosmetic treatment process for reducing and/or preventing the signs of ageing of keratin materials such as the skin, by application of such a composition.

The present invention relates to novel process for making oil-in-water nanoemulsions. The oil phase contains oil selected from the group consisting of triglyceride oil and/or petrolatum and a C.sub.8 to C.sub.16 fatty acid just be added during preparation; and the aqueous phase contains specific N-acyl derivatives of carboxylic amino acid as primary emulsifier.

Provided is a method for preparing an oil-in-water type emulsion composition, the method comprising a step for stirring and emulsifying a composition containing components (A), (B), (C) and (D) below and then treating under a high shear pressure of 30-300 Mpa, wherein (A) is 5-35 mass % of an acrylic-silicone graft copolymer, (B) is 5-35 mass % of volatile oil, (C) is 2-15 mass % of polyoxyethylene sorbitan fatty acid ester having average addition mole number of ethylene oxide (EO) of 10 or more and HLB of 11 or more, and (D) is 15-88 mass % of water.

The present invention relates to a self-emulsifiable composition including a monoacyl phospholipid, a diacyl phospholipid, oils and fats, and a polyhydric alcohol, in which the content ratio between the monoacyl phospholipid and the diacyl phospholipid is in the range of monoacyl phospholipid:diacyl phospholipid=1:9 to 9:1 as a mass ratio.

Disclosed herein are compositions, having nanosized droplets, wherein the nanosized droplets may contain a cannabinoid oil, a dietically acceptable carrier oil, a surfactant, and water. Also disclosed herein are methods of making and using the same.
