Benefits of technology

[0225]The present invention can also be used in a compact hair care formulation. A compact formula is a formula which delivers the same benefit to the consumer at a lower usage level. Compact formulations and methods of making compact formulations are described in US Application Publication No 2009 / 0221463A1.

Problems solved by technology

Unfortunately, such care polymers are incompatible with a variety of other consumer product ingredients, for example, anionic surfactants, and / or are expensive due to the cost of silicone raw materials and the silicone emulsification step that is required to make such silicones useful in products.
Fortunately, Applicants recognized that the source of the incompatibility and stability issues was the charge of current care polymers and such polymers' stiffness as due to such polymers' high glass transition temperature.

example 1

[0325]To an addition funnel is added 15.43 g of poly(isobutene)-succinic anhydride (available from BASF Corp. of Florham Pike, N.J. under the trade name Glissopal®-SA,) in 143.7 g of toluene. This solution is slowly added to a 1 L round-bottomed flask equipped with a water jacketed condenser and magnetic stir bar containing 48.75 g of aminopropylmethylsiloxane-dimethylsiloxane copolymers of amine equivalent 2000 g / mol (available from Shin-Etsu Silicones, Akron, Ohio under the name X-22-3908A-base) in 439.1 g of toluene at 90° C. This gives a 1:1 anhydride:amine stoichiometry. After addition, the reaction is cooled and stirred at room temperature. A 250.24 g sample is removed from the flask, precipitated into methanol, extracted with isopropanol, and dried in vacuum at 50° C. Polyamic acid copolymer (13.92 g) is obtained as a yellow material with 20% (by weight) poly(isobutene) as determined by H-1 NMR.

[0326]To an addition funnel is added 15.43 g of poly(isobutene)-succinic anhydride of number average molecular weight 1000 Da (available from BASF Corp. of Florham Pike, N.J. under the trade name Glissopal®-SA) in 143.7 g of toluene. This solution is slowly added to a 1 L round-bottomed flask equipped with a water jacketed condenser and magnetic stir bar containing 48.75 g of aminopropylmethylsiloxane-dimethylsiloxane copolymers of amine equivalent 2000 g / mol (available from Shin-Etsu Silicones, Akron, Ohio under the name X-22-3908A-base) in 439.1 g of toluene at 90° C. This gives a 1:1 anhydride:amine stoichiometry. After addition, the reaction is cooled and stirred at room temperature. After removing a 250.24 g sample, the reaction is brought to reflux to remove toluene / water. The reaction is then cooled, precipitated into methanol, extracted with isopropanol, and dried in vacuum at 50° C. Polyimide copolymer (19.84 g) is obtained as a yellow material with 22% (by weight) poly(iso...

Abstract

The present application relates to care agents, for example care polymers, and compositions such as consumer products comprising such care agents, as well as processes for making and using such care agents and such compositions. The performance of the care polymers that Applicants teach, can be further increased by following the emulsification teaching of the present specification and / or combining such care polymers with silicone materials.
