Embodiment 1

[0111] Sorghum bicolor extract containing 20-30% potency of apigenin chloride was prepared according to the following preparation method.

[0112] Sorghum bicolor leaf extract was obtained by alcohol-water (95° ethanol) extraction in an acidic medium (0.2% HCl) at an extraction temperature of 35°C at a ratio of solvent volume to mass of Sorghum bicolor leaf . The sorghum plant extract was then oven-dried at 40° C. for 24 hours and sieved at 200 μm.

[0113] The yield of the extract was 22.42% coloring matter.

[0114] The extract thus obtained has a potency of 21% by weight of apigenin.

[0115] First of all, the purpose of this example is to show that: compared with composition B, composition A of the present invention can be stored stably, wherein composition A contains sorghum bicolor extract, and emulsion containing organomodified polysiloxane ( water in silicone) as the carrier; composition B contains sorghum bicolor extract, and the emulsion (oil-in-water) without org...

Abstract

The invention relates to cosmetic and dermatological emulsion. The emulsion is characterized by comprising at least one aqueous phase, at least one fatty phase, at least one flavylium salt which is unsubstituted in position 3; which is substituted with at least one radical chosen from hydroxyl and alkoxy radicals; and which is, for example, obtained at least one of synthetically, from a plant extract, and from an enriched plant extract, in an amount which is effective for artificially coloring the skin, for example, effective for obtaining, 30 minutes after application of the emulsion to a fair skin in an amount of 2 mg / cm2, a darkening of the skin color characterized in the L*a*b* colorimetric measuring system by a DELTAL* ranging from -0.5 to -20, and at least one organomodified silicone, where the emulsion is configured as at least one of a cosmetic and a dermatological emulsion.

Description

technical field [0001] The invention relates to a cosmetic or dermatological emulsion, characterized in that the emulsion contains: [0002] - at least one aqueous phase, and [0003] - at least one fatty phase; [0004] - at least one 3-position unsubstituted zothium salt compound, which is substituted by at least one hydroxyl or alkoxy group, which is obtained synthetically or from a plant extract containing the compound, or from a concentrated (enriched ) plant extract, the content of the compound is at 2mg / cm 2 An effective amount that can be applied to fair skin (fair) for 30 minutes to deepen the color of the skin, and the darkening of the skin is characterized by: * a * b * In the colorimetric assay system, ΔL * Values ​​are -0.5 to -20, [0005] - at least one organomodified polysiloxane. Background technique [0006] Having a healthy appearance is very important these days, and a tan is always a sign of good health. However, the natural...
