Problems solved by technology

[0007] Furthermore, even though users can associate the presence of deposits of these compositions on the lips with a barrier effect against external intrusions, in some cases the deposits are perceived as too heavy, too greasy, or even sticky
[0008] Finally, it can be observed that with compositions in the form of emulsions, in some cases the composition is not easy to spread, which leads to deposits of uneven color and thickness

Embodiment 1

[0460] Compositions were prepared according to the ingredients listed in the table below (percentages are by weight of raw materials unless otherwise stated).

[0461]

[0462] step:

[0463] Distearyl hectorite was mixed in almond oil and propylene carbonate in a Rayneri deffloculator.

[0464] The oily phase is prepared by mixing all ingredients in a double skillet and once the mixture is homogenized, the previously obtained bentonite gel is added to it.

[0465] Homogenize and add wax at 80°C and homogenize all ingredients in a Raney blender.

[0466] The aqueous phase was prepared independently by mixing the ingredients in a Raney blender with stirring and allowing the temperature to stabilize at 60°C.

[0467] Subsequently, an emulsion is prepared by slowly pouring the aqueous phase thus obtained onto the previous fatty phase (stirring in a Morritz; 3000-4000 rpm).

[0468] The resulting mixture was allowed to cool to ambient temperature with stirring (with butterfl...

Embodiment 2

[0475] Compositions were prepared according to the ingredients listed in the table below (percentages are by weight of raw materials unless otherwise stated).

[0476]

[0477] step:

[0478] Disteardimethylammonium hectorite was mixed in almond oil and propylene carbonate in a Raney blender.

[0479] Subsequently, at 80° C., the remaining ingredients of the oily phase were added to the previous mixture in the double boiler with mixing.

[0480] Homogenize all ingredients in a Raney blender.

[0481] The aqueous phase was prepared separately by mixing the ingredients (except Aquacoat ECD) by stirring in a Raney blender and allowing the temperature to stabilize at 60°C.

[0482] Subsequently, an emulsion is prepared by slowly pouring the aqueous phase thus obtained onto the previous fatty phase (stirring in a Morritz; 3000-4000 rpm).

[0483] The resulting mixture was allowed to cool to ambient temperature with stirring (with butterfly blades).

[0484] Finally, the Aqua...

Embodiment 3

[0491] Compositions were prepared according to the ingredients listed in the table below (percentages are by weight of raw materials unless otherwise stated).

[0492]

[0493] step:

[0494] Disteardimethylammonium hectorite was mixed in vegetable oil and propylene carbonate in a Raney blender.

[0495] Subsequently, at 80° C., the remaining ingredients of the oily phase were added to the previous mixture in the double boiler with mixing.

[0496] Homogenize all ingredients in a Raney blender.

[0497] The aqueous phase was prepared separately by mixing the ingredients (except Aquacoat ECD) by stirring in a Raney blender and allowing the temperature to stabilize at 60°C.

[0498] Subsequently, an emulsion is prepared by slowly pouring the aqueous phase thus obtained onto the previous fatty phase (stirring in a Morritz; 3000-4000 rpm).

[0499] The resulting mixture was allowed to cool to ambient temperature with stirring (with butterfly blades).

[0500] Finally, the A...

Abstract

This invention relates to a composition, in the form of a water-in-oil emulsion, containing: at least 6% by weight in relation to the total weight of the composition, of at least one non-volatile hydrocarbon-based oil H1 chosen from plant oils or non-volatile triglycerides with a molecular weight greater than 400 Da, non-volatile non-polar hydrocarbon-based oils with a molecular weight greater than 350 Da, non-volatile ester oils with a molecular weight greater than 350 Da, and mixtures thereof; optionally less than 5% by weight in relation to the total weight of said composition of non-volatile hydrocarbon-based oil(s) H2 chosen from C10-C26 alcohols, preferably monoalcohols, non-volatile triglycerides with a molecular weight less than or equal to 400 Da, non-volatile ester oils with a molecular weight less than or equal to 350 Da, non-volatile non-polar hydrocarbon-based oils with a molecular weight less than or equal to 350 Da, dialkyl carbonates, and mixtures thereof; at least 15%by weight of water with respect to the total weight of said composition; at least one nonionic hydrocarbon-based or silicone surfactant; and at least one polar hydrocarbon-based wax chosen from beeswaxes, synthetic beeswaxes, (poly)oxyalkylenated hydrocarbon waxes, the oxyalkykenated residue(s) being C2-C4 or (poly)glycerolated; alcohol waxes, and mixtures thereof.

Description

technical field [0001] The present invention relates to a composition intended to be applied to the lips in the form of a liquid inverse emulsion. [0002] The invention also relates to a method of caring for the lips by applying said composition to the lips. Background technique [0003] A tinted or clear moisturizing composition, such as a lipstick or lip serum, is usually used. In this regard, various solid or liquid formulations have been developed. [0004] In particular, there are today some interesting conventional compositions for moisturizing the lips and / or especially for dry and chapped lips. More specifically, these compositions work by forming an occlusive barrier on the surface of the lips, thereby helping to keep moisture in the lips to improve the sensory properties (softness, etc.) of the lips. [0005] However, this mode of action is not long-lasting. In particular, once the composition is no longer applied to the lips, the moisturizing effect associate...
