Appeal No. 94-1495
Application 07/972,342
Claim 1 is illustrative of the subject matter on appeal and
correctly reads as follows : 2
1. In a hair care composition containing an organic anionic
surfactant and an organosilicon conditioning additive, the
improvement comprising the organosilicon conditioning additive
being a mixture of an amine functional silicone and a trisiloxane
polyether, the amine functional silicone having the formula:
R 'Q SiO[R 'SiO] [R'QSiO] SiQ R '
3-z z 2 x y z 3-z
wherein R' denotes an alkyl group of 1 to 4 carbons or a phenyl
group with the proviso that at least 50 percent of the total
number of R' groups are methyl; Q denotes an amine functional
substituent of the formula ) R''Z in which R'' is a divalent
alkylene radical of 3 to 6 carbon atoms and Z is a monovalent
radical selected from the group consisting of ) NR ''', and
2
) NR'''(CH )nNR '''; wherein R''' denotes hydrogen or an alkyl
2 2
group of 1 to 4 carbons; and n is a positive integer having a
value of from 2 to 6; z has a value of 0 or 1; x has an average
value of 25 to 10,000; y has an average value of 0 to 100 when z
is 1, y has an average value of 1 to 100 when z is 0; with the
proviso that in all cases y has an average value that is not
greater than one tenth the average value of x; the trisiloxane
polyether having the formula:
Ra
