Specialty sulfonic acid-based surfactants make up a rather large portion of surfactant production in the United States. Approximately 136,000 metric tons of specialty sulfonic acid-based surfactants were produced in 1992, which included alpha-olefin sulfonates, sulfobetaines, sulfosuccinates, and alkyl diphenyl ether disulfonates (64). These materials found use in the areas of household cleaning products, cosmetics (qv), toiletries, emulsion polymerization, and agricultural chemical manufacture. 

Saccharin is the most economical sweetener available. It is 300 times (8% sucrose solution sweetness equivalence) more potent than sugar and its price in 1996 was about 6.05/kg, ca 0.02/(kg-sweet unit). Sugar, on the other hand, was ca 0.77/kg, which is 39 times more expensive than saccharin on equal sweetness basis. Consequentiy, the low cost and high stabiUty of saccharin render it the sweetener of choice for dentifrices (qv), other toiletry products, and pharmaceuticals (qv). 

Talc sold to the cosmetics and baby powder markets must meet the Cosmetic, Toiletries and Fragrance Association (CTFA) specifications (8). For mote stringent appHcations there ate United States Pharmacopeia (USP) and Pood Codex specifications.

Cosmetics and Toiletries. Citric acid and bicarbonate are used in effervescent type denture cleansers to provide agitation by reacting to form carbon dioxide gas. Citric acid is added to cosmetic formulations to adjust the pH, act as a buffer, and chelate metal ions preventing formulation discoloration and decomposition (213—218).

Propylene Oxide. Propylene oxide [75-56-9] (qv), C H O, is a higher homologue of ethylene oxide that boils at 35°C. Propylene oxide is not as germicidaHy active as ethylene oxide (291), but has one distinct advantage it hydrolyzes to produce nontoxic propylene glycol (292), allowing use for treating foods. Three hours at 37°C reduced the microbial count of cocoa powder by 50—70% and molds by 90—99% (293). Powdered cosmetics and toiletries are treated with 1—2% of Hquid propylene oxide in sealed containers, and the temperature is raised to cause vaporization and increased activity (294). 

Over the last 30 years, ethanol s role as a solvent has increased sharply, while its role as a chemical intermediate has declined. In 1990, 59% of the 890 X 10 L demand was used for solvents and the remaining 41% was used for chemical intermediates (283). In 1960, solvents accounted for only 24% of the demand. The 1990 solvent uses were toiletries and cosmetics, 33% coatings, inks, and proprietary blends, 29% detergents and household cleaners, 14% external pharmaceuticals, 7% insecticides and disinfectants, 7% and miscellaneous, 10%. Ethanol demand for solvent appHcations has been fairly stable in recent years, growing at an average aimual rate of 2%. VOC regulations could impact its solvent use, particularly in areas like California, where ethanol in aerosols like hair spray and deodorants have come under scmtiny. 

Substantial quantities of UPVC are also used for blow moulded containers for such diverse materials as consumable liquids such as fruit squashes, liquids for household use such as detergents and disinfectants, cosmetics and toiletries, and pharmaceuticals. For most of these applications UPVC is in competition with at least one other polymer, particularly poly(ethylene) terephthalate (Chapter 25), polyethylene (Chapter 10), polypropylene (Chapter 11) and, to a small extent, the nitrile resins (Chapter 15). The net result is that in recent years there has been some replacement of PPVC in these areas, in part because of problems of waste disposal.
