Appeal 2006-2632
Application 09/881,807
BACKGROUND
The invention relates to oxidizing compositions for use on keratinous
materials, such as hair. The oxidizing compositions are used, for example,
for treatments such as dyeing, bleaching, permanent waving, or
relaxing/straightening. According to Appellants, in preparing these
compositions, it is important to achieve chemical stability of the oxidizing
agent and physical stability of the oxidizing composition.
According to Appellants, they have discovered that the use of at least
one cationic homopolymer, at least one fatty alcohol, at least one
alkoxylated fatty alcohol, and at least one fatty amide in an oxidizing
composition may result in a physically stable composition.
Claim 1 is illustrative of the invention and is reproduced below:
1. A composition comprising:
(a) at least one cationic homopolymer comprising repeating units
of formula (I):
Wherein:
-R1, R2, and R3, which may be identical or different, are each chosen
from H, alkyl groups, and alkenyl groups; and
R4 is chosen from groups comprising at least one quaternary amino
group;
