Project at a Glance	Contents on the CD ROM
Octamethylcyclotetrasiloxane (D4) is an odorless, colorless non-oily silicone fluid used primarily to make other silicone materials. During this manufacturing process, virtually all of the material is consumed, with only a tiny amount of D4 remaining. In a small handful of personal care products,D4 can be used as an additive providing certain application-related benefits preferred by consumers. Cyclic dimethylsiloxane tetramer D4 tetracyclomethicone, Siloxane,octamethylcyclotetra Siloxanes and Silicones octamethylcyclotetra Siloxanes octamethylcyclotetra-Octamethylcyclotetrasiloxane Octamethylcyclotetrasiloxane, Cyclo(octamethyl)tetrasiloxane Octamethylcyclotetrasiloxane (OMCTS), a common constituent of household products, triggers the transformation of bismuth to the volatile toxic derivative trimethylbismuth by methanosarcina barkeri, Which is a representative member of the sewage sludge microflora. Comparative studies with the ionophores monensin and lasalocid, Which induce effects similar to those observed for indicated that the stimulation of bismuth methylation is not specific for the siloxane and suggested that the stimulation observed is mainly due to facilitated membrane permeation of the metal ion The cyclic siloxane octamethylcyclotetrasiloxane and the linear siloxane hexamethyldisiloxane have numerous industrial and consumer applications and thus have the potential for human exposure. The present study was undertaken to examine potential estrogenic and antiestrogenic activities of D4 and HMDS Octamethylcyclotetrasiloxane or D4 is a low molecular weight siloxane (LMWS) fluid with a low surface tension, low aqueous solubility, high lipid solubility, and low vapor pressure It is present at 40-60% by weight in personal care products such as antiperspirants, cosmetics, and hair care products Because of its widespread use in these products, a typical woman is exposed to an average daily intake (ADI) of 0.158 mg/kg/day (11.1 mg/day) of D4 from daily use of such products bioavailability, breast implant, D4, implantation, inhalation, Octamethylcyclotetrasiloxane, PBPK, physiologically based pharmacokinetic model, risk assessment, silicone Synthetic silicon-containing compounds (silicones) are usedin a variety of consumer products, e.g., skin care products, antiperspirants, antacids, and antiflatulence agents Octamethylcyclotetrasiloxane is a base fluid in a number of personal care products, with excellent spreading and lubrication properties and unique volatility characteristics. Octamethylcyclotetrasiloxane can be used in bath oils, deodorants, skin creams, lotions, suntan and shaving products, nail polishes. Octamethylcyclotetrasiloxane has faster drying time in low voc formulate in hair sprays There is potential for human exposure to cyclic siloxanes by the respiratory route. To determine the pharmacokinetics of octamethylcyclotetrasiloxane (D4), a material commonly found in personal care products, the respiratory intake and uptake of D4 were measured in 12 healthy volunteers on two occasions. The deposition in continuous wave (cw) mode was compared with pulsed conditions	General Bioavailability of octamethylcyclotetrasiloxane Public consultation meeting on proposed measures for octamethylcyclotetrasiloxane Octamethylcyclotetrasiloxane Octamethylcyclotetrasiloxane compound summary Potential estrogenic and ant estrogenic activity of the cyclic siloxane Octamethylcyclotetrasiloxane description Uses Acute respiratory exposure human volunteers octamethylcyclotetrasiloxane Appendix of the screening assessment for the challenge Effect of octamethylcyclotetrasiloxane on methylation of bismuth by methanosarcina barkeri 556-67-2 use of octamethylcyclotetrasiloxane(d4) International chemical safety cards Octamethylcyclotetrasiloxane bmse000765 - data Octamethylcyclotetrasiloxane-based, low-permittivity organosilicate coatings Route-specific differences in distribution characteristics of octamethylcyclotetrasiloxane in rats analysis using models MSDS Antifoam af Csl 502 / silicone potting and encapsulating sealant Enhance-plus Lotioncrafter lc995 Nuflex® 302 high temperature gasket making silicone sealant 3c85-0 Octamethylcyclotetrasiloxane sc-250610 Dow corning(r) 244 fluid Siltech s-701 Ges waterford plant 260 hudson river rd Silco incorporated Waterford plant 260 hudson river rd waterford ny 12188 Momentive performance material 260 hudson river Octamethylcyclotetrasiloxane spectrum Scientific committee on consumer products sccp opinion Specialty cleanerproducts Patent Process for producing octamethylcyclotetrasiloxane Method of polymerizing silicone fluid Treated silica for oil absorption Methods for preparing decamethyl cyclopentasiloxane Cosmetic composition comprising at least two volatile linear alkanes and at least one nonprotein cationic polymer Octamethylcyclotetrasiloxane azeotropes Silicones for power treatment powers having surface treated with said silicones and cosmetic materials containing said powers Cosmetic composition Preparation of triethyl dimethyl siloxalane Cosmetic material Method for wash-protecting the color of artificially dyed keratin fibers Study Bioavailability of ctamethylcyclotetrasiloxane (d4) after exposure to silicones by inhalation and implantation Environmental risk assessment report: octamethylcyclotetrasiloxane Identification of metabolites of octamethylcyclotetrasiloxane (d4) in rat urine Microbial degradation of octamethylcyclotetrasiloxane Percutaneous absorption studies of octamethylcyclotetrasiloxane using the human skin/nude mouse model.
