Disclosed herein are sprayable compositions comprising: a complex of (A) at least one charged (or pseudo-charged) polymer having a molecular weight of about 125,000 amu or more; and (B) a least one oppositely charged, rheology modifying, crosslinked polymer having at least one carboxylic functional group. The composition may provide a spray with a median particle size of less than about 175 &#x3bc;m. Also disclosed are methods for preparing the compositions as well as creating the spray. The invention enables the spray of the high molecular weight charged (or pseudo-charged) polymer in any number of uses including personal care and performance chemicals application.

Sprayable composition comprising high molecular weight charged polymer

Compositions are disclosed that impart one or more durable hair styling benefits. The durable styling compositions comprise at least a first compound having anhydride, diacid, diester, or half-acid/half-ester functionality, and a second compound having at least one amine moiety or hydroxyl functional group. In one embodiment the durable styling composition takes the form of a leave-in product. The durable styling compositions are heat-activated, which may be accomplished through the use of a heated styling tool like a flat-iron, curling iron, and/or hair dryer. The benefits include shine, conditioning, softness, defrizzing, and improved hair alignment, and endure for up to 5 wash cycles or more without having to reapply the durable styling composition nor heat.

Durable styling compositions and the uses thereof

Family of non-homopolymers synthesized from N-vinyl lactam, (meth)acrylic acid, hydrophobic (meth)acrylic ester of a straightchain or branched-chain alkyl alcohol and monomer selected from the group consisting of functionalized and unfunctionalized: dialkyl maleates, dialkyl fumarates, and combinations thereof. The non-homopolymers may exhibit solubility in one or more lower molecular weight alcohols and/or a glass transition temperature greater than 80&#xb0; C.
