Definition and Structure The ingredients in this report are all siloxane polymers. Each silicone atom is further substituted with hydrogen, methyl, or other substituents (Figure 1). “Methicone” (CAS No. 9004-73-3) means that most of the silicone atoms in the polymer backbone each have 1 methyl group and 1 hydrogen atom, while “Dimethicone” (CAS No. 9006-65-9) means that  Distributed for Comment Only -- Do Not Cite or Quote most silicone atoms in the polymer back bone have 2 methyl substituents. The remaining ingredients in this report have 1 or 2 of the substituents on the silicone atoms replaced with an alternative functional group (e.g., Hexyl Methicone (CAS No. 1873-90-1) is substituted with hexyl-chains (C6)). The definitions and idealized structures of all the ingredients included in this report are provided in Table 1. Figure 1. Methicones, wherein R is hydrogen, methyl, or other substituents The polymerization of linear methicones, however, often results in a mixture of polymers (chains of variable lengths and molecular weights, including oligomers) and cyclic compounds.8 Dimethicone is a mixture of fully methylated linear siloxane polymers end-blocked with trimethylsiloxy units.2 Methicone is a linear monomethyl polysiloxane. The other ingredients included in this review are siloxane polymers of Dimethicone and Methicone. Viscosity is expressed in both dynamic and kinematic measurements, and is directly correlated with molecular weight and the degree of polymerization of a molecule, i.e., the longer the polymer chains, the more viscous the liquid polymer.3 Most of the viscosities reported in previous and current data have been described in kinematic centistokes (cSt; cm2/s), and are converted to the standard, dynamic, Pascal*second (Pa⋅s; kg/m⋅s), where specific gravity, or relative density, values were … [kırpıldı - bölüm toplam 8957 karakter]
