When producing novel textures for cosmetic use, the rheology modifier is often more important than the surfactant system. Lubrizol produced a presentation of novel textures it has called Sweet Escape where many different possibilities are discussed.
One of interest here is how Novethix L-10 Polymer (INCI: Acrylates/beheneth-25 methacrylate copolymer) can interact with water-soluble amphiphilic ingredients such as polysorbate 20 for the creation of versatile textures. While maintaining the level of Novethix L-10 at 2.5% in water, adding about 0.125% polysorbate gives a jellylike texture; increasing the polysorbate 20 gives a ringing gel with a crushed ice texture until at about 1.2% a memory shape effect useful for hair styling is obtained. This is discussed in detail in the presentation and various possible products are suggested.
