The polyether-modified structures are the most important silicone surfactants currently in use, examples of which are shown in Fig. 2.8.1. These are known by many names, including silicone polyethers, polyethermethylsiloxanes (PEMSs), dimethicone copolyols,...

A significant amount of information regarding the uses of silicone surfactants is still found primarily in the patent art, but the major applications have recently been reviewed in journals. Silicone (or siloxane) surfactants are also called silicone polyethers (SPEs), polyalkylene oxide silicone copolymers, silicone poly(oxyalkylene) copolymers and silicone glycols. The International Cosmetic Ingredient Nomenclature and the Cosmetic, Toiletry and Fragrance Association (CTFA) adopted name is dimethicone copolyol. 

Peel-off masks are applied in a uniform layer on the skin and upon drying and removal produce a sensation of skin tightness and cleansing action. Peel-off masks are marketed to consumers with normal, oily, combination, and acne-prone skin types. These masks are believed to perform the functions of skin exfoliation, hydration, and purification. They are based on plasticized polyvinyl alcohol. Hydrophilic emollients (e.g., ethoxylated fatty acid or alcohol derivatives, dimethicone copolyol) and humectants (e.g., glycerin, propylene glycol, sorbitol) are added to prevent moisture loss and cracking of polyvinyl alcohol film.

Resins, types of polymers, are the thickening and hardening agents that, without pigments, serve as colorless nail protectors resembling clear furniture lacquer. These agents include nitrocellulose (collodion) and different acrylate and polyester/polyurethane copolymers. Copolymers include chemicals such as methacrylic acid, isobutyl methacrylate, toluenesulfona-mide formaldehyde resin, phthallic anhydride/trimellitic anhydride/glycol copolymer, tosylamide/formaldehyde resin, and dimethicone copolyol. 

Silicones have been claimed to improve combing, enhance feel, reduce flyaway, increase shine, reduce drying time, and lock in color [54-56], The most frequently used silicone is dimethicone, which is a polydimethylsiloxane. Other important silicones are dimethiconol, which is a dimethylsiloxane terminated with hydroxyl groups, amodimethicone, which is an amino-substituted silicone, dimethicone copolyol, which is a dimethylsiloxane containing polyoxyethylene and/or propylene side chains, and cyclomethicone, which refers to a class of cyclic dimethyl polysiloxanes ranging from trimer to hexamer ... 

Dimethicone copolyols provide lighter conditioning effects due to their solubility in water and low level of substantivity. Because of that, they are less effective in rinse-off products. They are used, however, in leave-on products, such as hairsprays, styling mousses, and gels. 

The primary conditioning agent used in most two-in-one shampoos is dime-thicone. Other related silicones have also been used, either in a primary or secondary capacity, including dimethiconol, amodimethicone, and dimethicone copolyol. Because most of these materials are not soluble in water, two-in-one shampoos are generally oil-in-water emulsions, requiring the use of a suitable stabilizer or emulsifying agent.

NF, cetyl alcohol NF, polysorbate 60 NF, myristyl alcohol NF, sorbitan monostearate NF, lactic acid USP, and benzyl alcohol NF (1%) as preservative. Cream and lotion contain a synthetic, broad-spectrum, antifungal agent ciclopirox (as ciclopirox olamine). The chemical name is 6-cyclo-hexyl-l-hydroxy-4-methyl-2(l H)-pyridone, 2-aminoeth-anol salt. Each gram of gel contains 7.70 mg ciclopirox in a gel consisting of purified water USP, isopropyl alcohol USP, octyldodecanol NF, dimethicone copolyol 190, car-bomer 980, sodium hydroxide NF, and docusate sodium USP. 

Silicone emollients are often used in skin products such as moisturizers and antiperspirants because of their ease of spreading and nonoily feel. In addition, the volatile cyclomethicones can provide a cooling sensation as they evaporate after application. Microemulsions can be formed by using nonionic alkoxylated surfactants or dimethicone copolyol surfactants as shown in Table 15.
