Abstract
Abstract The invention relates to the use, in cosmetic compositions for cleansing and/or removing make-up in particular from the skin, mucous membranes, eyes, and/or the hair, of at least one succinic anhydride derivative corresponding to one of the formulae I and II:GOOC-(HR)C-C(HR')-COO-(CmH2mO)n-H(I)GOOC-(HR)C-C(HR')-COO-(CmH2mO)n-CpH2p-O-CO-(HR')C-C(HR)-COOG(II).

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
191 words
A method of cleansing and/or removing make-up from the skin, mucous membranes, semi-mucous membranes, eyes, and/or exoskeleton, said method comprising applying to said skin, mucous membranes, semi-mucous membranes, eyes, and/or exoskeleton a cosmetic or hygiene composition comprising at least one succinic anhydride derivative of the following formulae I or II: GOOC--(HR)C--C(HR')--COO--(C.sub.m H.sub.2m O).sub.n --H (I) GOOC--(HR)C--C(HR')--COO--(C.sub.m H.sub.2m O).sub.n --C.sub.p H.sub.2p --O--CO--(HR')C--C(HR)--COOG (II) in which: one of the radicals R and R' is a linear or branched C 6 -C 22 alkyl or alkenyl radical and the other radical is a hydrogen atom; n ranges from 2 to 100; m is equal to 2 or 3 and may vary along the polyoxyalkylene chain; p is equal to 2 or 3; G is a hydrogen atom, a C 1 -C 6 alkyl group, a radical --(C m' H 2m' O) n' H, in which n' ranges from 2 to 100 and m' is equal to 2 or 3 and may vary along the chain, or a cation, provided that when G is a radical --(C m' H 2m' O) n' H, then at least one of m and m' is equal to 2.
Claim 2
Independent Claim
191 words
A method of cleansing and/or removing make-up from the skin, mucous membranes, semi-mucous membranes, eyes, and/or exoskeleton, said method comprising applying to said skin, mucous membranes, semi-mucous membranes, eyes, and/or exoskeleton a cosmetic or hygiene composition comprising at least one succinic anhydride derivative of the following formulae I or II: GOOC--(HR)C--C(HR')--COO--(C.sub.m H.sub.2m O).sub.n --H (I) GOOC--(HR)C--C(HR')--COO--(C.sub.m H.sub.2m O).sub.n --C.sub.p H.sub.2p --O--CO--(HR')C--C(HR)--COOG (II) in which: one of the radicals R and R' is a linear or branched C 6 -C 22 alkyl or alkenyl radical and the other radical is a hydrogen atom; n ranges from 2 to 100; m is equal to 2 or 3 and may vary along the polyoxyalkylene chain; p is equal to 2 or 3; G is a hydrogen atom, a C 1 -C 6 alkyl group, a radical --(C m' H 2m' O) n' H, in which n' ranges from 2 to 100 and m' is equal to 2 or 3 and may vary along the chain, or a cation, provided that when G is a radical --(C m' H 2m' O) n' H, then at least one of m and m' is equal to 2.
