Abstract: The application describes a cosmetic agent for temporarily reshaping keratin fibres, in particular human hair, comprising a film former and a cosmetic carrier, wherein the film former comprises at least one neutralization product of chitosan with at least one organic acid and at least one non-ionic propylene oxide-modified starch, which cosmetic agent is also substantially free of a fully synthetic film former.

Abstract: Cosmetic compositions for temporarily deforming keratinic fibers, cosmetic products, and methods for temporarily deforming keratinic fibers are provided herein. In one embodiment, a cosmetic composition for temporarily deforming keratinic fibers includes at least one uncrosslinked anionic polymer, at least one uncrosslinked cationic polymer, and water in a total amount of from about 80 to about 98% by weight, in relation to the total weight of the cosmetic composition.

Abstract: A cosmetic agent for the temporary styling of keratinic fibers, in particular human hair, containing, in a cosmetic support, with respect to its total weight, a) from about 0.05% to about 5.0% by weight of at least one (meth)acrylamidopropyltrimethylammonium salt copolymer; b) from about 0.5% to about 10% by weight of polyimide, the uses thereof and a method employing this agent.

Abstract: A cosmetic product comprising A. a dispensing device with spray valve, B. a container connected to the dispensing device, comprising a cosmetic agent containing b1) at least one cross-linked anionic polymer (AP) comprising specific monomers, b2) at least one cationic polymer (KP) comprising at least one structural unit of the formula (I), at least one structural unit of the formula (II) and at least one structural unit of the formula (III), b3) at least one nonionic polymer (NP), b4) propellant in a total amount of from about 0 to about 95% by weight, based on the total weight of the cosmetic agent found in the container.

Abstract: The invention relates to cosmetic agents for temporarily shaping keratin fibers, a method for temporarily shaping keratin fibers using said agents, and the use of said agents for temporarily shaping keratin fibers. The polymer combination of at least one specific anionic polyurethane polymer and a specific silicone-containing cationic copolymer used according to the invention results in excellent straightening properties and excellent protection of hair from damage during straightening.

Abstract: A cosmetic agent for the temporary styling of keratinic fibers, in particular human hair, containing, in a cosmetic support, with respect to its total weight, a) from about 0.05% to about 5.0% by weight of at least one (meth)acrylamidopropyltrimethylammonium salt homo- or copolymer; b) from about 0.5% to about 10% by weight of polyimide, the uses thereof and a method employing this agent.

Abstract: A cosmetic agent for the temporary styling of keratinic fibers, in particular human hair, containing, in a cosmetic support, with respect to its total weight, a) from about 0.1% to about 2.0% by weight of chitosan or chitosan derivative b) from about 0.5% to about 7.0% by weight of polyimide, its use and a method employing this agent.
