POLYMERS AND HAIR STYLING COMPOSITIONS THEREOF
OF THE INVENTION
 The invention relates to
fixative polymers, compositions comprising such fixative polymers and their
applications in personal care compositions, and more specifically, to crystal
clear hair styling gel compositions.
BACKGROUND OF THE INVENTION
 EP13836 (assignee: Rohm
& Haas) discloses emulsion polymers, which comprise (i) 20-69.5% by weight
of (meth)acrylic acid, (ii) 0.5 to 25% by weight of a monomer of the formula CH2=C(R)-C-(O)-O-(CH2CH2O)N-R0,
in which R is H of CH3, n is at least 2 and R0 is C8-C30-alkyl,
and (iii) at least 30% by weight of a C1-C4-alkyl(meth) acrylate.
This patent covers various hydrophobic monomer combinations with various
acrylates in a plurality of weight ratios. However, there is no suggestion of
the cross-linked polymer of the present invention, its combination of desirable
properties or its use in personal care compositions.
 US7205271 (assignee: ISP
Investments Inc.) discloses a rheology modifier/hair styling resin which is a
cross-linked, linear poly(vinyl amide/polymerizable carboxylic acid) copolymer
exhibiting advantageous hair care properties. The resin exhibits high viscosity
and long lasting curl retention.
 US7217752 (assignee: Noveon Inc.)
discloses an aqueous surfactant composition having cross-linked
alkali-swellable acrylate copolymer as rheology modifier and an insoluble
silicone compound. The copolymer is derived from ethyl acrylate, methacrylic
acid, cross-linking agent and a hydrophobe.
 US7288616 (assignee: Lubrizol
Advanced Materials Inc.) discloses multipurpose alkali soluble associative
polymers which are polymerization products of methacrylic acid; ethyl acrylate;
first and second associative monomers along with a crosslinking agent and a
chain transfer agent.
 While different rheology
modifiers, including associative alkali-soluble thickeners, have been disclosed
in various applications, there still is the desire to find a composition which
provides suitable thickening as well as the combination of stringent
rheological and other properties desired for personal care applications.
 Polymers for personal care
compositions must not only perform the functional aspects of thickening,
suspension and stabilization, but must also provide enhanced appearance to the
finished product, superior flow and pour properties, crystal clarity, high
humidity curl retention (HHCR), a smooth, light, cushiony feel in use,
non-sticky (no tack) after drying, and a pleasant after-feel.
 Despite the polymers proposed
by the aforementioned patents and other approaches described in the published
literature, there still exists a need for improved fixative polymers to achieve
the desired rheological and aesthetic properties.
 Thus, better styling
polymers are desired which impart improved rheological, aesthetic and
