Personal products

Medical aerosols are included ia the personal products category and ia 1989 amounted to approximately 60 million units. 

Personal products are the fastest growing segment of the aerosol industry and represent the largest of the categories. An iacrease in the use of hair spray as well as deodorants and antiperspirants accounts for the major growth. Increase in industrial aerosol automotive products was also large in the 1980s. 

Generally, aerosol packaging consists of many dehcately balanced variables. Even hardware design plays an important part. For example, valves that produce considerable breakup are used for the warm sensation desired in some personal products. 

Quick-breaking foams consist of a miscible solvent system such ethanol (qv) [64-17-5] and water, and a surfactant that is soluble in one of the solvents but not in both. These foams are advantageous for topical appHcation of pharmaceuticals because, once the foam hits the affected area, the foam coUapses, deUvering the product to the wound without further injury from mechanical dispersion. This method is especially usehil for treatment of bums. Some personal products such as nail poHsh remover and after-shave lotion have also been formulated as quick-breaking foams. 

Hydrocarbons have, for the most part, replaced CFCs as propellants. Most personal products such as hair sprays, deodorants, and antiperspirants, as well as household aerosols, are formulated using hydrocarbons or some form of hydro-carbon—halocarbon blend. Blends provide customized vapor pressures and, if halocarbons are utilized, a decrease in flammabiUty. Some blends form azeotropes which have a constant vapor pressure and do not fractionate as the contents of the container are used. 

Household and personal products dominate surfactant technology Hterature. Sales volume per product ia these categories is large enough to justify research and investment ia large manufactuting facilities. Industrial appHcations represent smaller sales volumes per product. Research and especially technical service is often conducted by the user or by a service company that suppHes a variety of items to the consuming iadustry. 

Whereas the general office community reaped the benefits (and endured the pain) of the rise of the personal computer, the scientific and technical market was forced to wait. Chemists used spreadsheets and suffered through word processors that did not know what a chemical stmcture was. However, there is now a good variety of personal productivity tools that have been designed specifically for the chemist. 

Local ventilation is used to diminish or, preferably, to prevent exposure to contaminants (including heat). This includes protection of persons, products, or animals from hazardous and/or nuisance contaminants. This task is not specific for local ventilation and different definitions exist. One is the following ... 

The concentration levels observed in sewage sludge show that UV filters originate mainly from private households, but besides this, surface runoff and industrial discharges may be considered as additional sources. This indicates that in addition to sunscreens, cosmetics and other personal products, UV filters from plastics, textiles, and other materials can be released to the environment by either volatilization or leaching.

Triethanolamine is a viscous liquid widely used as a corrosion inhibitor, a surface-active agent and an intermediate in various products including metalworking fluids, oils, fuels, paints, inks, cement, cosmetic and personal products, as well as herbicide and algicide formulations. Occupational exposure may occur by inhalation and dermal... 

Poly(succinimide-co-sodium aspartate), (I), was previously prepared [2] by the author and used in biodegradable and personal product applications. 

More than 6 000 tonnes of polycyclic musks (Figure 4.6) have been produced worldwide since 1996 [47]. They are present at concentrations of up to several mg/g of product [48] as fragrances in perfumes, detergents, soaps, lotions, air fresheners, and other scented personal products. These compounds are hydrophobic and persistent, bioaccumulate in food webs, have toxic effects, and are widespread in surface waters, sediments, fish, and human adipose tissues and...
