Abstract: The present invention relates to a cosmetic composition useful for washing and conditioning keratin fibres. Such compositio n comprises: - one or more anionic surfactants, - one or more amphoteric or zwitterionic surfactants, - one or more non ionic surfactant s chosen from polyethoxylated esters of fatty acids, - one or more polyols, - one or more cationic and/or amphoteric polymers, and - optionally, one or more silicones. The invention also relates to a cosmetic process for washing and/or conditioning keratin fibres using this composition.
Cosmetic composition comprising a particular combination of
surfactants, a polyol, a cationic or amphoteric po lymer and
optionally a silicone
The present invention relates to a cosmetic composition fo5 r
washing and/or conditioning keratin fibres, and in particular human
keratin fibres such as hair, which comprises a particular combinatio n
of surfactants, one or more polyols, one or more polymers of cationic
and/or amphoteric nature, and, optionally, one or more silicones.
10 The invention also relates to a cosmetic method for washing
and/or conditioning keratin fibres using this composition.
Finally, the invention relates to the use of such a compositio n
for washing and/or conditioning keratin fibres.
It is common practice to use detergent cosmetic compositions
15 such as shampoos, based essentially on surfactants, for washing
keratin fibers especially such as the hair. These compositions are
applied to the keratin fiber, which are prefer ably wet, and the lather
generated by massaging or rubbing with the hands make s it possible,
after r insing with water, to remove the diverse t ypes of soiling
20 initially present on the hair and the scalp.
These compositions contain substantial contents of "detergent"
surfactants, which, are generally of anionic, non ionic and/or
amphoteric type, and particular ly of anionic t ype.
Admittedly these compositions have a good washing power, but
25 the intrinsic cosmetic properties associated with them nevertheless
remain fair ly poor, owing in particular to the fact that the relativel y
aggressive nature of such a cleaning tr eatment can, in the long run,
lead to more or less pronounced damage to the hair fibre, this damage
being associated in particular with the gradual removal of the lipids or
30 proteins contained in or on the surface of the fibres.
Thus, in order to improve the cosmetic properties of the above
detergent compositions, and more particularly those which ar e to be
3
applied to sensitized hair ( i.e. hair which has been damaged or made
brittle, in particular under the chemical action of atmospher ic agents
and/or hair treatments such as permanent-waving, dyeing or
bleaching), it is now common to introduce additional conditioning
agents such as mineral or plant oils into these compositions. Thes5 e
conditioners are intended mainly to repair or limit the harmful or
undesirable effects induced by the var ious treatments or aggressions to
which the hair fibres ar e subjected more or less repeatedly. These
conditioners may, of course, also improve the cosmetic behaviour of
10 natural hair.
However, the compositions containing such conditioners are
generally presented in the form of emulsions or dispersions having
varying degrees of thickness and they often have an opaque appearance
that is not very attractive. More and more, consumers seek cosmetic
15 products that have an original visual appearance.
Moreover, these products may cause some drawbacks, due in
particular to the presence of oils.
In particular, these compositions r ich in fatt y substances ma y
be difficult to apply to the hair and may be difficult to remove, in
20 particular ma y require long rinsing.
Accordingly, there is a real need to make available
compositions, in particular washing compositions for human keratin
fibres such as hair, not presenting the drawbacks mentioned
hereinabove, i.e. that present an attractive visual appearance and that
25 can be applied easily to said fibres, and be rinsed quickly while
leading to enhanced cosmetic properties.
The composition should also have good detergent properties,
and present a good tolerance especially with respect to the skin,
mucous membranes, the scalp and the eyes.
30 The Applicant has now discovered that a cosmetic compositio n
comprising a particular combination o f surfactants, one or more
polyols, one or more polymers of cationic and/or amphoteric nature,
and optionally one or more silicones, makes it possible to achieve the
objectives outlined above.

Thus, the subject of the invention is especially a cosmetic
composition comprising:
- one or more anionic surfactants,
- one or more amphoteric or zwitter ionic surfactants,
- one or more non ionic surfactant s chosen fro5 m
polyethoxylated esters of fatty acids,
- one or more polyo ls,
- one or more cationic and/or amphoteric polymers, and
- optionally, one or more silicones.
10 The composition according to the invention has ver y good
cleaning properties. It provides a homogeneous foam that spreads
easily and uniformly on keratin fibres and cleanses the keratinous
substrate such as the hair and the scalp in a ver y gentle wa y. The
composition has the further advantages of being applied easily and of
15 being rinsed off quickly.
The composition according to the invention furthermore
exhibits high cosmetic properties, and especially affords a good
conditioning of keratin fibres such as the hair, including when these
fibres are sensitized. Indeed, the composition of the inventio n
20 provides, for instance, excellent smoothness, softness and
disentangling to the hair. The composition further provides a good
manageability of the keratin fibres, and a good control of frizz and
volume.
In addition, the composition according to the invention has a n
25 attractive and original visual appearance. It touches, feels and behaves
like an oil. It is a clear and transparent composition, which is ver y
pleasant to the co nsumers.
The composition has an oil-like texture during application, but
cleans the hair like a shampoo
30 The invention also relates to a cosmetic method for washing
and conditioning keratin fibres using this composition.
Finally, the invention relates to the use of such a compositio n
for washing and conditioning keratin fibres.

invention will emerge even more clear ly on reading the descriptio n
