Sprays. Aerosol spray emulsions are of the water-in-oil type. The preferred propellant is a hydrocarbon or mixed hydrocarbon—hydrofluorocarbon. About 25 to 30% propellent, miscible with the oil, remains in the external phase of the emulsion. When this system is dispensed, the propellant vaporizes, leaving behind droplets of the w/o emulsion (Fig. 2b). A vapor tap valve, which tends to produce finely dispersed particles, is employed. Because the propellant and the product concentrate tend to separate on standing, products formulated using this system, such as pesticides and room deodorants, must be shaken before use. 

Eatty acid ethoxylates are used extensively in the textile industry as emulsifiers for processing oils, antistatic agents (qv), softeners, and fiber lubricants, and as detergents in scouring operations. They also find appHcation as emulsifiers in cosmetic preparations and pesticide formulations. Eatty acid ethoxylates are manufactured either by alkaH-catalyzed reaction of fatty acids with ethylene oxide or by acid-catalyzed esterification of fatty acids with preformed poly(ethylene glycol). Deodorization steps are commonly incorporated into the manufacturing process. 

You and your children can be exposed to 1,4-di chlorobenzene in your home if you use products such as 1,4-dichlorobenzene-treated toilet bowl cleaners or mothballs containing 1,4-dichlorobenzene. You should not let your child play with or drink toilet bowl water that has been treated with 1,4-di chlorobenzene. Do not let your children rub mothballs or cleaners containing 1,4-di chlorobenzene on their skin. Because 1,4-di chlorobenzene may be found in the home as a pesticide and bathroom deodorizer and in mothballs, these items should be stored out of reach of young children to prevent accidental poisonings. Always store household chemicals in their original labeled containers never store household chemicals in containers children would find attractive to eat or drink from, such as old soda bottles. Keep your Poison Control Center s number by the phone. 

DDT and PCBs remain the most widespread contaminants in human milk around the world. Other common contaminants of mother s milk include flame retardants, pesticides, wood preservatives, toilet deodorizers, and dry-cleaning fluids. 

My young son s health was damaged by chemicals (in particular pesticides, insecticides and herbicides) and he was affected both mentally and physically. As an infant James had a major exposure to pesticides and he had severe reaction to vaccinations when he was four months old. Also, we had a flea plague here and our home was sprayed. He became very ill. When he was eighteen months old our home was renovated and painted with the normal toxic paint products. He continued to have exposures at school. I had no idea they were fogging the trees and around the classrooms with pesticides. At school he was also exposed to toxic paint products and cleaning products, chemical deodorizers in the toilets and chemically perfumed products on the staff and children. 

The liquid used to scrub the vapors is previously condensed deodorizer distillate that is chilled, recycled, and drawn off as necessary to maintain a constant level in the scrubber. The condensate may entrap vapors of pesticides if they get this far in the refinery. Deodorizer distillate is rich in tocotrienols or tocopherols, some of which have vitamin E... 

Pesticides may be periodically inttoduced into indoor air by direct application (e.g. insect sprays and bombs, disinfectant sprays and room deodorizers). In addition, there are often sources that continually emit vapors into the living space (e.g. continuous evaporation of residues from crack and crevice treatments and emissions from pest-control strips or other devices). Whether used inside the home or office, or outside on the lawn or garden, pesticides accumulate on indoor surfaces, especially in carpet dust, and also in upholstery and in or on children s toys (Lewis et al 1994b, 1999 Simcox et al., 1995 Nishioka et al 1996, 1999 Gurunathan et al., 1998). 

Although the process is commonly named deodorization, it is actually a combination of three different effects on the oil (1) stripping Stripping of volatile components (free fatty acids, odorous compounds, tocopherols, sterols, and contaminants such as pesticides and light polycyclic aromatic hydrocarbons, etc.), (2) actual deodorization Removal of different off-flavors, and (3) temperature effect Thermal destruction of pigments and unwanted side reactions such as cis-trans-iso-merization, polymerization, conjugation, and so on. 

The vapor pressure of PCB can vary within a wide range. The more volatile PCBs have a vapor pressure around 40-75 mbar, which is similar to the vapor pressure of some organo-chlorine pesticides. Our own lab deodorization trials showed that PCBs and dioxins can be stripped from fish oil without degradation of the 00-3 fatty acids (eicosapentaenoic acid, EPA, and docosahexaenoic acid, DHA) provided that the deodorization pressure is very low (>2 mbar) (Table 10). Other studies showed that deodorization at 230°C and 5 mbar was insufficient to remove a PCB heat-transfer agent from contaminated rice bran oil (28). 

Deodorizer distillate flow is much lower in the case of chemical refining (0.2-0.5% of the oil flow to the deodorizer). Consequently, contaminant concentration in the distillate can theoretically become 200-500 times higher than in the crude oil. For pesticides, the observed concentration factor is significantly lower, mainly because of thermal decomposition of some pesticides and incomplete condensation of volatile pesticides in the vapor scmbber. The limited amount of data available in the literature, combined with our own research figures, indicate that pesticide concentration in soybean, sunflower seed, and rapeseed deodorizer distillate is usually...

Pharmaceutical and nonpharmaceutical aerosol products are used as convenient forms of delivery and include personal deodorant sprays, cosmetic hair lacquers and sprays, perfume and cologne sprays, shaving lathers, toothpaste, surface pesticide sprays, and paint sprays. Also included are various household products such as spray starch, waxes, polishers, cleaners, and lubricants. A number of veterinary and pet products have been put into aerosol form. Food products and dessert toppings and food spreads are also available.
