(20-25 DKK pr. kg) Omtrent samme pris som siloxanerne Lidt mindre end cyclopentasiloxan Ikke muligt at estimerer da alternativet ikke direkte erstatter siloxanerne * Anvendes som alternative til cyclomethicone og paraffin, men kan ikke substituere alle siloxanens egenskaber N/A : CAS Nr. er ikke oplyst eller fundet - stoffer er ikke fundet i den 1. opdaterede liste med ingredienser anvendt i kosmetiske produkter I EU (INCI 2000)
1 Introduction 1.1 What are siloxanes and silicones? Siloxanes are compounds in which silicon atoms (Si) are linked via oxygen atoms (O), each silicon atom bearing one or several organic groups. According to the main rules for classification of chemicals (IUPAC) the compounds are designated siloxanes, but most often the term "silicones" are used. When talking about products and materials, "silicones" are nearly always used, and this term will be used here as well. The term "siloxanes" will be used when we talk about single compounds, or when we have a more chemical approach to the subject. In other words: Siloxanes are building blocks for silicone products. The chemical names of the compounds most often include the string "siloxane", but in particular in cosmetics and toiletries names including methicone are used instead, e.g. dimethicone derived from dimethyl silicone; synonymous with dimethylsiloxane. Another used synonym is poly(oxy(methylsilylene)). To add to the confusion about the terms, several of the compounds recorded in the Danish Product Register, listed in Annex 3, are designated "silicones and siloxanes". The alternating silicon and oxygen atoms form a backbone structure to which different side chains are linked. The side chains may form cross links which influence the properties of the polymer. The silicon and oxygen atoms may be linked into cyclic or linear structures, and we distinguish between linear siloxanes and cyclic siloxanes. Linear siloxanes Linear polysiloxanes are characterised by the functional side chains attached to the Si-O backbone and the endgroups terminating the structure (illustrated by R5). The side groups may be the same group or several different side groups may be attached (illustrated by R1-R4). Linear polydimethyl siloxanes are the most important industrial polysiloxanes. In their most simple form they consist of methyl side-chains and methyl terminal groups, polydimethylsiloxane (PDMS). The shorter linear polysiloxanes are, like some of the cyclic siloxanes mentioned below, volatile. The shortest, hexamethyldisiloxane, is volatile with a boiling point of 100°C, and is used in cos- R5 CH3 Si H3C CH3 O R1 Si O R2 n R3 Si O R4 Polydimethylsiloxane CH3 Si CH3 H3C O CH3 Si CH3 CH3 Si O CH3 Hexamethyl disiloxane O n CH3 Si CH3 CH3 CH3 CH3 CH3 Si R5 CH3 m Si CH3 19
