10 Claims

1. A method for improving the spreading properties of an oil-in-water emulsion for topical use,

wherein said oil-in-water emulsion comprises for 100% of its weight:

from 95% to 50% wt % of a cosmetically acceptable aqueous phase;

from 5% to 50% wt % of a fatty phase, said fatty phase comprising, for 100% of the weight of said fatty phase, from 1% to 12% wt % of at least one oil-in-water surfactant and from 88% to 99% wt % of at least one oil and/or one wax,

the method comprising adding into said oil-in-water emulsion from 1% to 25% wt % of said oil-in-water emulsion of a mixture of saturated hydrocarbons that are cyclic or acyclic, linear or branched,

wherein said mixture of saturated hydrocarbons comprises, for 100% of its weight,

either:

80-100 wt % of branched alkanes,

0-15 wt % of linear alkanes, and

0-5 wt % of cycloalkanes, and

wherein from 95% by weight to 100% by weight of said cyclic or acyclic, linear or branched saturated hydrocarbons comprise from fifteen to nineteen carbon atoms and up to 5% by weight of said cyclic or acyclic, linear or saturated branched hydrocarbons comprise less than fifteen or more than nineteen carbon atoms,

or:

40-100 wt % of branched alkanes,

0-20 wt % of linear alkanes, and

0-40 by weight of cycloalkanes and

wherein 100% by weight of said cyclic or acyclic, linear or branched saturated hydrocarbons comprise from fifteen to nineteen carbon atoms,

wherein said oil-in-water emulsion is free of shea butter,

wherein said oil-in-water emulsion is free of silicone oil and silicone derivatives, and

wherein said oil-in-water emulsion further comprises at least one terpolymer selected from the group consisting of

terpolymers of acrylic or methacrylic acid in combination with 2-methyl-[(1-oxo-2-propenyl)aminol-1-propanesulfonic acid (AMPS) and N,N-dimethylacrylamide,

terpolymers of acrylic or methacrylic acid in combination with AMPS, and acrylamide, and

linear, branched, or crosslinked terpolymers with one monomer having a free partially salified or totally salified strong acid function, in combination with

one neutral monomer, and one monomer of formula: CH₂═C(R′₃)—C(═O)—[CH₂—CH₂—O]_n—R′₄wherein R′₃represents a hydrogen atom or a methyl radical, R′₄represents a linear or branched alkyl radical comprising from eight to thirty carbon atoms, and n represents a number that is greater or equal to one and less or equal to 50.
