Description

[Technical field]

[0001] The present invention relates to the field of cosmetics, and more particularly to a long-lasting liquid cosmetic composition that enhances the color intensity of makeup and allows these intense colors to last longer. These cosmetics can be used, for example, as liquid lipstick formulations. [Background technology]

[0002] The use of lipstick as a means for coloring the lips has undergone rapid growth, so that lipstick is now a popular beauty product. Originally, lipstick compositions were solid products that melted on the lips when applied, but with the growth of the lip makeup market, various textures have been developed, ranging from liquid to solid. Regardless of its texture, a cosmetically acceptable lipstick should have a uniform color and exhibit long wear.

[0003] To be attractive to consumers, it is also desirable to offer a range of shades in one lip product. However, colorants are compatible either in the water phase (dyes) or in the oil phase (pigments). For example, it is difficult to combine dyes and pigments in anhydrous compositions, since water-soluble dyes are not compatible in anhydrous compositions. To mix water-soluble dyes into a fatty continuous phase composition, for example, document WO 2017 / 162599 discloses preparing an emulsion, in which the dispersed aqueous phase contains the water-soluble dye. Incorporation of the dye into the aqueous dispersed phase of the emulsion often leads to dye bleeding and non-uniform formulation.

[0004] Preparing liquid compositions containing pigments and dyes with uniform color and low viscosity (below 300 mPa·s) remains a technical challenge.

[0005] Furthermore, when long wear is required, it is conventional to use volatile oils, which evaporate quickly after makeup application, thus leaving a non-sticky, long-lasting colored film on the lips. However, the presence of volatile oils further reduces the viscosity of liquid formulations, which makes the suspension of pigments even more difficult and can affect the homogeneity of the formulation. Summary of the Invention

[0006] It is therefore an object of the present invention to provide a liquid, anhydrous composition of low viscosity comprising at least one water-soluble dye, wherein said water-soluble dye is homogeneously dispersed, and wherein the liquid, anhydrous composition exhibits long wear, color intensity, and long-lasting, intense color.

[0007] It is to the applicant's credit that the applicant has discovered that water-soluble dyes, when combined with a specific surfactant, namely polyglyceryl-10 pentaoleate, and a polyol in specific weight ratios, can be homogeneously and stably mixed into a low viscosity liquid anhydrous composition in the presence of at least one volatile oil.

[0008] Thus, according to a first aspect, the present invention provides a method for producing ... composition comprising the steps of: A liquid, anhydrous composition comprising: (a) at least one water-soluble dye; (b) at least one polyol, and (c) Polyglyceryl-10 Pentaoleate (d) at least one volatile oil; Including, The relative weights of (a) / (b) / (c) are in the range 1 / 0.6 / 8≦(a) / (b) / (c)≦1 / 6 / 18.

In a preferred embodiment, the liquid anhydrous composition of the invention is a lip product, such as a liquid lipstick or lip gloss.

[0085] The formulation of Comparative Example B3, using Polyglyceryl-3 Diisostearate instead of Polyglycerol-10 Pentaoleate, resulted in a non-homogeneous composition after mixing: the dye did not dissolve and formed aggregates.

[0086] The formula of Comparative Example B4, using Polyglyceryl-3 Polyricinoleate instead of Polyglyceryl-10 Pentaoleate, results in a composition that is not homogenous and shows liquid on top after mixing.

Then cool to room temperature to constitute Phase 1. 4) All dyes, glycerin and Polyglyceryl-10 pentaoleate are combined in a beaker, heated to 95° C., mixed for 1 hour, then cooled to room temperature to constitute the second phase. 5) Add phase 2 to phase 1 and mix for 5 to 10 minutes until the dye is well dispersed. 6) Add pigment to Phase 1 and mix for 10 minutes until the pigment is well dispersed. 7) Slowly add the silica to Phase 1 with mixing and continue mixing for 10 minutes. 8) Trimethylsiloxysilicate is pre-dispersed in isododecane and slowly poured into Phase 1 with mixing, continuing mixing for 10 minutes.

[0090] Steps 5 to 8 are carried out at room temperature.
