Vinyl shower curtain

Test your water for contaminants, then purchase the appropriate antidote. Install a showerhead filter as well this will reduce your exposure to chlorine, among other chemicals found in municipal water. (While in the bathroom, get rid of that vinyl shower curtain it isn t a plastic you want around your growing baby. It s a known carcinogen—which contains phthalates—petroleum derivatives that... 

Diphenyl Antimony 2-Ethylhexoate. This (Fig. 5.4-IV) is approved for use in vinyl shower curtains, wallpaper, upholstery, and rug underlay. 

Plasticizers are small molecules added to soften a polymer by lowering its glass transition temperature or reducing its crystallinity or melting temperature. The most widely plasticized polymer is poly (vinyl chloride). The distinctive odor of new vinyl shower curtains is caused by the plasticizer, for example.

In an attempt to identify sources of APs, levels of 4-tcrt-NP, A-tert-OP and some APEs were determined in a variety of household cleaners, cosmetics, personal care products, and household products a vinyl shower curtain had the highest level of 4-tert-NP (in the range of >100 to 1,000 pg/g) in the items surveyed (Dodson et al. 2012). To what extent FCMs could be a source contributing to household air and dust levels of NP or OP is not known. 

Di(2-ethylhexyl) phthalate is widely used as a plasticizer in flexible vinyl products. Plastics may contain from 1 to 40% di(2-ethylhexyl) phthalate by weight and are used in consumer products such as imitation leather, rainwear, footwear, upholstery, flooring, wire and cable, tablecloths, shower curtains, food packaging materials and children s...

Di-ethyl hexyl phthalate (DEHP) is a softening agent commonly used in plastics such as polyvinyl chloride (PVC). It is found in products such as telephone cords, kidney dialysis machine tubing, medical plastic bags, shower curtains, vinyl wall coverings, and children s toys.

Polyfvinyl chloride), the polymer produced from the polymerization of vinyl chloride, is known as PVC. Straight-chain polyfvinyl chloride) is hard and rather brittle branched polyCvinyl chloride) is the soft elastic vinyl conunonly used both as a substitute for leather and in the manufacture of such things as garbage bags and shower curtains (Section 28.2). Poly(acrylonitrile) looks like wool when it is made into fibers. It is marketed under the trade names Orion (DuPont), Creslan (Sterling Fibers), and Acrilan (Monsanto). 

A plasticizer can be added to a polymer to make it more flexible. A plasticizer is an organic compound that dissolves in the polymer, lowering the attractions between the polymer chains, which allows them to slide past one another. Dibutyl phthalate is a commonly used plasticizer. It is added to poly(vinyl chloride)— normally a brittle polymer— to make products such as vinyl raincoats, shower curtains, and garden hoses.

Worldwide, over 6 million tons of phthalates are produced annually. They are colorless liquids having the consistency of oil, sparingly soluble in water, but very soluble in plastic matrices (as well as in adipose body tissue.) At least 95% of the production ends up in plastics and other consumer products. They are also used in cosmetic formulations such as nail polish (imparts crack resistance) and in hair spray. Its best-known use is in plastics as a plasticizer, mostly in PVC, to soften the hard, brittle plastic. It is the same plastic, PVC, that is used in siding and water pipes that is also used in soft flexible automobile seat covers and in shower curtains, hi the latter cases, the PVC is intimately compounded with up to 50-60% of an organic phthalate to plasticize the resin. Notebook covers, children s toys, rainwear, and backpack components used by children as well as some flexible transparent medical tubing and blood bags are also made from plasticized PVC material. Phthalates being only dissolved in the polymer (not covalently bound) can leach out into fluids in contact with the vinyl under some conditions. 

Vinyl chloride/vinylidene chloride monomers can be polymerized by emulsion pol3rmerization. Poly(vinyl chloride) (E-PVC) product is mostly applied as the dried form. It is spray-dried and milled to form fine powders ("crumbs") which is mixed with plasticizer to form a plastisol, i.e., dispersion of pol) vinyl chloride) particles in liquid organic media. The plastisol is poured into molds to make rubber doUs, shower curtains, embossed wall coverings and many of other common objects. In packing materials, especially for food packaging, the films of poly(vinylidene chloride) latexes are used, which are highly impermeable for both, oxygen and water vapor.

Polyvinyl chloride (PVC) is often produced by suspension or emulsion polymerisation. It is used extensively in producing PVC pipes for construction. Impact modifiers are often added to strengthen the material. PVC is also used in plastisols for dipped coatings, in shower curtains, and in vinyl leather. Nonvolatile plasticisers are necessary in such applications where the material must remain flexible. Because PVC is a very hydrophobic polymer with good barrier properties, it makes an effective obstacle to oxygen and water vapour in packaging films.
