Makeup-fixing cosmetic composition

Abstract

The present invention proposes a new way of having makeup last longer on the skin. The present invention comprises the supply and use of a new liquid cosmetic composition comprising the combining of styrene/acrylates copolymer and Biosaccharide Gum-4 preferably in an aqueous solution. This makeup-fixing composition is intended to be sprayed on top of makeup compositions, after they have been applied to the skin, so as to delay the deterioration of makeup compositions and thus having the makeup last longer.

Claims

1. A makeup fixing cosmetic composition comprising: an association of styrene/acrylates copolymer and Biosaccharide Gum-4; between 0.25% and 20% styrene/acrylates copolymer; between 0.012% and 0.36% Biosaccharide Gum-4; between 1% and 10% rice powder; between 0.05% and 0.5% Buddleja officinalis flower extract; between 1% and 30% rose water; between 1% and 30% cornflower water; between 1% and 30% hammamelis water; between 1% and 30% sage water; between 0.1% and 3% perfume or perfumed composition; and qs distilled water.

2. The composition according to claim 1, characterized in that it is an aqueous solution in liquid form.

Description

DESCRIPTION OF THE FIGURES

(1) FIG. 1: is a photograph of a hand made up with 3 lines of dark eye shadow, on top of which the association of styrene/acrylates copolymer and Biosaccharide Gum-4 according to the invention (on the hand to the left), only styrene/acrylates copolymer (on the hand in the center), and only Biosaccharide Gum-4 (on the hand to the right) have been applied.

(2) FIG. 2: is a photograph of a hand made up with one line of dark eye shadow and 2 opposing arrows, showing that the pad is applied in one direction and then in the other during passes in accordance with the protocol of the example.

(3) FIG. 3: Results of the example: is photographs of a hand made up with 3 lines of dark eye shadow, on top of which the association of styrene/acrylates copolymer and Biosaccharide Gum-4 according to the invention (on the hand to the left), only styrene/acrylates copolymer (on the hand in the center), and only Biosaccharide Gum-4 (on the hand to the right) have been applied, the hand being photographed at T0, then T after 6 passes, T after 12 passes, T after 18 passes, and T after 24 passes.

EXAMPLE

(4) Evaluation and comparison of the makeup fixing action over time for 3 cosmetic formulations: DSTQ (styrene/acrylates copolymer and Biosaccharide Gum-4 according to the invention) DST (styrene/acrylates copolymer only) P (Biosaccharide Gum-4 only)

(5) Test Element

(6) Designation: DST Q, DST and P

(7) Container: glass spray bottles

(8) Form: aqueous liquids

(9) Storage condition: ambient temperature

(10) Site of application: back of the hand

(11) Conditions of use The bottle DST Q contains an association of styrene/acrylates copolymer (0.5%) and Biosaccharide Gum-4 (0.084%) in water The bottle DST contains a quantity of styrene/acrylates copolymer (0.5%) in water The bottle P contains a quantity of Biosaccharide Gum-4 (0.084%) in water

(12) Principle of the Study The principle of the test is based on determining the makeup fixing power of 3 cosmetic compositions, after successive rubbing. The aim is that of demonstrating that the association of styrene/acrylates copolymer and Biosaccharide Gum-4 has an action synergy having a makeup fixing power that is 2 to 8 times greater, over time, than if the styrene/acrylates copolymer or the Biosaccharide Gum had been used alone. The results were taken at T0, T+6 passes, T+12 passes, T+18 passes and T+24 passes; supported by photographs (FIG. 3).

(13) Course of the Study

(14) Material Used: Makeup: dark eye shadow by the cosmetic trademark MAC 3 formulations to test (DSTQ, DST, P), each contained in a glass spray bottle Makeup remover pads: pad changed every 6 passes and between one formulation and another

(15) Test Protocol:

(16) 3 lines of dark eye shadow, of equal amounts, are painted onto the back of the same hand.

(17) One spray selected from one of the 3 formulations DST Q, DST and P is vaporized onto each makeup line (FIG. 1).

(18) Using a clean pad, each of the 3 made up regions is rubbed in turn. The pressure applied to the pad is substantially the same during each pass, made in one direction and then in the other (FIG. 2). Every 6 passes, the results are recorded, the photograph taken, and the pad changed. 6 passes on formulation DST Q pad changed 6 passes on formulation DST pad changed 6 passes on formulation P pad changed

(19) Evaluation of the results at T+6 passes

(20) Photographs taken at T+6 passes 6 passes on formulation DST Q pad changed 6 passes on formulation DST pad changed 6 passes on formulation P pad changed

(21) Evaluation of the results at T+12 passes

(22) Photographs taken at T+12 passes 6 passes on formulation DST Q pad changed 6 passes on formulation DST pad changed 6 passes on formulation P pad changed

(23) Evaluation of the results at T+18 passes

(24) Photographs taken at T+18 passes 6 passes on formulation DST Q pad changed 6 passes on formulation DST pad changed 6 passes on formulation P pad changed

(25) Evaluation of the results at T+24 passes

(26) Photographs taken at T+24 passes

(27) Results:

(28) The results of the photographs are shown in FIG. 3. The intensity of the color remaining on the back of the hand was noted, on a scale of 1 to 10, following every 6 passes of the pad. The intensity of the remaining color makes it possible to demonstrate the makeup fixing power of each of the formulations, over time.

(29) 10 corresponds to the maximum color intensity, and thus to the highest fixing power, and 0 to a lack of remaining color, and thus a fixing power that is time-limited.

CONCLUSIONS

(31) In view of the results, the formulation DST Q is the most fixing formulation and achieved a result of 8/10 after 24 passages, thus demonstrating the strength of the fixing power thereof: 8 times greater than the formulation DST or P;

(32) The association of styrene/acrylates copolymer+Biosaccharide Gum-4 has a true action synergy that is far greater than if styrene/acrylates copolymer or Biosaccharide Gum-4 had been used alone.
