Abstract
The present invention relates to a composition, in particular a cosmetic composition, comprising, in a physiologically acceptable medium, at least glyceryl caprylate, 1,3-propanediol and phytic acid or any of the salts thereof, said composition being free from perlite. The present invention further relates to a composition, in particular a cosmetic composition, comprising, in a physiologically acceptable medium, at least glyceryl caprylate, 1,3-propanediol and phytic acid or any of the salts thereof.
Claims
1. A cosmetic composition, comprising, in a physiologically acceptable medium, 0.01% to 5% by weight of glyceryl caprylate with respect to the total weight of the composition, 0.5% and to 10% by weight of 1,3-propanediol with respect to the total weight of the composition and 0.01% to 1.5% by weight of phytic acid or any of the salts thereof with respect to the total weight of the composition, said composition being free from perlite.
2. The composition according to claim 1, wherein the phytic acid salt is an alkaline phytic acid salt.
3. The composition according to claim 2, wherein the alkaline phytic acid salt is sodium phytate.
4. The composition according to claim 1, wherein it further comprises an alcohol other than 1,3-propanediol.
5. The composition according to claim 1, which further comprises 0.1% to 25% by weight of alcohol other than 1,3-propanediol with respect to the total weight of the composition.
6. The composition according to claim 2, wherein it comprises 0.01% to 5% by weight of glyceryl caprylate with respect to the total weight of the composition.
7. The composition according to claim 3, wherein it comprises 0.01% to 5% by weight of glyceryl caprylate with respect to the total weight of the composition.
8. The composition according to claim 1, which comprises 0.1% to 1.5% by weight of glyceryl caprylate; 0.5% to 10% by weight of 1,3 propanediol with respect to the total weight of the composition, and 0.05% to 0.3% by weight of phytic acid or any of the salts thereof with respect to the total weight of the composition.
9. The composition according to claim 1, which further comprises 0.1% to 10% by weight of a C2-C8 alcohol other than 1,3-propanediol with respect to the total weight of the composition.
Description
EXAMPLES
Example 1
Cosmetic Composition Formulations
(1) Two cosmetic compositions were prepared so as to be comparable in respect of the addition effect in the glycerol caprylate, sodium phytate and 1,3-propanediol composition.
(2) The compositions under test are as follows:
(3) TABLE-US-00001 TABLE 1 Composition 1 Comparative according to the composition 1C invention EU INCI (% by weight) (% by weight) BENZYL ALCOHOL 0.5 0.5 CETEARYL ALCOHOL 0.5 0.5 DICAPRYLYL CARBONATE 3 3 C12-16 ALCOHOLS (and) PALMITIC ACID (and) 4 4 HYDROGENATED LECITHIN (BIOPHILIC H from LUCAS MEYER COSMETICS) HELIANTHUS ANNUUS SEED OIL 3 3 BUTYROSPERMUM PARKII BUTTER 5 5 SODIUM PHYTATE (dermofeel ® PA-3 from DR — 0.1 STRAETMANS GmbH) SCLEROTIUM GUM 0.3 0.3 XANTHAN GUM 0.1 0.1 GLYCERIN 5 5 PROPANEDIOL (Zemea ® Propanediol from — 3 DUPONT TATE AND LYLE BIO PRODUCTS) ETHYLIC ALCOHOL. — 3 AQUA qs 100 qs 100 GLYCERYL CAPRYLATE (dermosoft ® GMCY — 0.5 from DR STRAETMANS GmbH) GLYCERYL STEARATE CITRATE 1 1 TOCOPHEROL 0.025 0.025 qs 100: Sufficient quantity to make up to 100% of the total weight of the composition
(4) The following examples summarize the results obtained by applying these compositions (comparative or according to the invention) to the facial skin, particularly around the eye contour, of a panel of six women:
(5) 0.30 ml of each formula was applied for each half-face, in a randomized fashion. The evaluation was performed immediately (2 minutes) after application versus bare skin, by expert beauticians.
(6) According to the Protocol
(7) The panel firstly evaluated the comparative composition versus bare skin, and secondly the composition according to the invention versus bare skin. As mentioned above, each application is performed on one half of the face, the other half of the face thus representing bare skin.
(8) In the interval between 2 applications, the panel removed the treatment completely and cleansed their face.
(9) The effects are rated on a 7-point scale that may be positive and/or negative, with a reference “parameter under evaluation not applicable for volunteer”.
(10) The summarized data are compiled in tables 2 to 5.
(11) TABLE-US-00002 TABLE 2 Effect on dehydration lines Cases Grading of effects Parameters concerned/ Accentuates Attenuates Overall under Total visibility visibility Score evaluation Formulas cases −6 −5 −4 −3 −2 −1 0 1 2 3 4 5 6 − + Dehydration Eyes Composition 1 6/6 1 4 1 18 lines according to the invention Comparative 1 2 3 8 composition 1C Face Composition 1 6/6 3 3 21 according to the invention Comparative 2 2 2 12 composition 1C
(12) It was observed that the composition according to the invention is more effective (markedly superior) in respect of attenuating dehydration lines, particularly on the face and around the eyes, than the comparative composition.
(13) TABLE-US-00003 TABLE 3 Effect on wrinkles cases Grading of effects Parameters concerned/ ACCENTUATES ATTENUATES OVERALL under total visibility visibility SCORE evaluation Formulas cases −6 −5 −4 −3 −2 −1 0 1 2 3 4 5 6 − + Wrinkles Lower Composition 1 6/6 2 3 1 18 eyelid according to the invention Comparative 4 2 4 composition 1C Cheeks Composition 1 4/6 3 1 [9] according to the invention Comparative 1 3 [−1] composition 1C Forehead Composition 1 6/6 5 1 2 according to the invention Comparative 6 0 0 composition 1C
(14) The composition according to the invention displays a markedly superior efficacy for attenuating wrinkles than the comparative composition on the lower eyelids, cheeks and forehead.
(15) TABLE-US-00004 TABLE 4 Effect on bags cases Grading of effects Parameters concerned/ ACCENTUATES ATTENUATES Overall under total visibility visibility score evaluation Formulas cases −6 −5 −4 −3 −2 −1 0 1 2 3 4 5 6 − + Uneven- Bags Composition 1 6/6 1 2 2 1 −1 5 ness in according to the skin invention surface Comparative 1 5 −1 composition 1C
(16) The composition according to the invention makes it possible to attenuate unevenness in the skin surface, particularly bags, better than the comparative composition. This action may be explained by the action of the composition on wrinkles. The effects observed with Composition 1 C are practically non-existent.
(17) TABLE-US-00005 TABLE 5 “Corrugated sheet” effect Grading of effects Very Relatively Very “Corrugated NONE slight Slight Moderate significant Significant significant Overall sheet” result 0 1 2 3 4 5 6 Score Composition 1 6 0 according to the invention Comparative 2 2 1 1 12 composition 1C
(18) The composition according to the invention thus exhibits a significant efficacy on dehydration lines with no “corrugated sheet” effect, unlike a comparative composition without the association according to the invention (glycerol caprylate, sodium phytate and 1,3-propanediol).
(19) Evaluation of Appearances of Formulations and Cosmetic Applications
(20) The comparative composition and the composition according to the invention have textures of gelled creams of relatively high densities.
(21) The comparative composition does not spread as well as the composition according to the invention.
(22) The composition according to the invention spreads in a slightly oily, silky and waxy film both on the face and between the fingers. The spreading thereof is thus completely satisfactory and pleasant.
(23) Unlike the comparative composition, the composition according to the invention has a superior skin texture after application. The composition according to the invention leaves a very light oily and silky residual film.
