Abstract

The present invention relates to a composition containing lipophilic phase (A), an emulsifying system (B), and an aqueous phase (C) that is preferably suitable for topical use, in particular cosmetic and/or dermatological use, in the form of a fine oil-in-water emulsion that is rich in oil and can be obtained by phase inversion, and to uses thereof in particular in the cosmetics or dermatological field.

First claim

The invention claimed is:

1. A composition in the form of an oil-in-water emulsion, comprising:
a lipophilic phase (A) present in an amount of from 60% to 80% by weight relative to a total weight of the composition, the lipophilic phase comprising from 30% to 100% by weight of one or more synthetic or mineral hydrocarbon-based oils having a molecular weight greater than or equal to 360 g/mol relative to a total weight of the lipophilic phase;
an emulsifying system (B) present in an amount of from 2 to 5% by weight relative to the total weight of the composition, wherein the composition has only a single emulsifier that is an ethoxylated fatty alcohol having an HLB ranging from 8 to 18 or only a mixture of ethoxylated fatty alcohols having an HLB ranging from 8 to 18;
an aqueous phase (C) present in an amount of from 10% to 30% by weight relative to the total weight of the composition;
wherein a weight ratio of the emulsifying system (B) to the lipophilic phase (A) is from 0.04 to 0.2.

2. The composition according to claim 1 , obtained by phase inversion emulsification.

3. The composition according to claim 1 , wherein a mean size of droplets the lipophilic phase (A) D[4.3] is 0.09 μm to 4 μm.

4. The composition according to claim 1 , having a viscosity at 25° C. of greater than or equal to 1 Pa·s.

5. The composition according to claim 1 , wherein the synthetic or mineral hydrocarbon-based oils having a molecular weight of greater than or equal to 360 g/mol comprise at least one member selected from the group consisting of fatty acid esters obtained from an alcohol comprising a saturated or unsaturated, linear or branched chain having from 1 to 24 carbon atoms and a fatty acid comprising a linear or branched chain having from 3 to 24 carbon atoms, the total sum of carbon atoms of said esters being greater than or equal to 24, and alkanes.

6. The composition according to claim 1 , wherein the synthetic or mineral hydrocarbon-based oils having a molecular weight of greater than or equal to 360 g/mol are comprise at least one member selected from the group consisting of 2-ethylhexyl palmitate, cetyl 2-ethylhexanoate, 2-octyldodecyl myristate, isocetyl stearate, isostearyl isostearate, 2-ethylhexyl stearate, octyldodecyl neopentanoate, cetearyl isononanoate, isodecyl isononanoate, pentaerythritol tetraisostearate, isotridecyl isononanoate, C12-C15 fatty alcohol benzoates, petroleum jelly, liquid petroleum jelly and hydrogenated isoparaffin.

7. The composition according to claim 1 , wherein the synthetic or mineral hydrocarbon-based oils having a molecular weight of greater than or equal to 360 g/mol are present in an amount of from 66.5% to 100% by weight relative to a total weight of oily constituents of the lipophilic phase (A).

8. The composition according to claim 1 , comprising at least one polyol.

9. The composition according to claim 8 , wherein the polyol comprises at least one member selected from the group consisting of glycerol, glycols and sugars.

10. The composition according to claim 8 , wherein the polyol is present in an amount of from 5 to 20% by weight relative to the total weight of the composition.

11. The composition according to claim 1 , wherein said composition is a cosmetic or dermatological composition.

12. The composition according to claim 1 , wherein said composition is a makeup-removing composition and/or a cleansing composition for the skin, the lips and/or the eyelashes, a composition for massaging facial skin and/or body skin, an exfoliating composition, an antisun composition or an aftersun composition, a shower care balm, a conditioner composition, a hair care balm, a shaving product, a mask, a slimming poultice, a massage balm, a lip repairing balm, or a balm for dry feet.

13. A process, comprising applying the composition according to claim 1 a keratin material.

14. The process according to claim 11 , wherein said composition is applied to skin, the lips and/or the eyelashes.
