Cosmetic or pharmaceutical composition comprising modified polyorganosiloxanes

摘要

Cosmetic or pharmaceutical compositions comprising one or more substituted aminopolyorganosiloxanes (SH) with substituted amino groups which are bonded to silicon atoms of the polysiloxane basic structure via alkylene bridges or mono- or oligo(alkylenamino)alkylene bridges, where the amino groups present in the aminopolyorganosiloxanes (SH) are substituted at least partially by a radical of the formula (ε)
T-CH2—CHOH—CH2—  (ε),
in which T is the radical of a surfactant monoalcohol polyglycol ether with emulsifier character,

the amino groups present in the aminopolyorganosiloxanes (SH) are substituted in the average ratio of at least 1.5 radicals of the formula (ε) per Si-bonded aminoalkyl group or amino-mono- or -oligo-(alkylenamino)-alkyl group, and

present amino groups are, if appropriate, acylated and/or alkylated and/or benzylated and/or protonated at least partially to give amide groups, are described.

1. A method for protecting and preserving color in colored keratin fibers, wherein the method comprises the step of contacting the colored keratin fibers with a treatment composition comprising at least one substituted aminopolyorganosiloxanes (SH) with substituted amino groups which are bonded to silicon atoms of a polysiloxane basic structure via alkylene bridges or mono- or oligo(alkylenamino)alkylene bridges, where the amino groups present in the aminopolyorganosiloxanes (SH) are substituted at least partially by a radical of the formula (ε)
T-CH2—CHOH—CH2—  (ε),in which T is the radical of a surfactant monoalcohol polyglycol ether with emulsifier character, wherein the monoalcohol polyglycol ether is of the following formula (II)
R1—(O—X)q—OH  (II)in which R1 is an alkylaromatic or aliphatic hydrocarbon radical having 9 to 24 carbon atoms, X is a C2-4 alkylene and q is 4 to 50, where at least 80% of the q alkylenoxy groups are ethylenoxy units, the amino groups present in the aminopolyorganosiloxanes (SH) being substituted in the average ratio of at least 1.5 radicals of the formula (ε) per Si-bonded aminoalkyl group or amino-mono- or -oligo-(alkylenamino)-alkyl group and optionally present amino groups can be acylated, alkylated, benzylated and/or protonated at least partially.
