摘要:
agricultural composition, cosmetic composition, household care composition, aqueous and non-aqueous emulsions thereof and coating composition. compositions comprising disiloxane surfactant compositions comprising a silicone composition comprising a silicone having the formula: mm ', where m = r = 1/2 ~; with r ^ 1 ^ selected from the group consisting of monovalent branched hydrocarbon radical of 3 to 6 carbon atoms er ^ 7 ^, where r ^ 7 ^ has the formula: r ^ 8 ^ r ^ 9 ^ r ^ 10 ^ sir ^ 12 each with independently selected from the group of monovalent hydrocarbon radicals having from 1 to 6 carbon atoms and monovalent aryl or alkaryl hydrocarbon radicals having from 6 to 13 carbon atoms er ^ 12 ^ is a divalent hydrocarbon radical having from 1 to 3 carbon atoms, r ^ 2 ^ and r ^ 3 ^ are each independently selected from the group of monovalent hydrocarbon radicals of 1 to 6 carbon atoms or r ^ 1 ^, with r An alkyl polyalkylene oxide of the general formula is: (c ~ 2 ~ h ~ 4 o) a (c ~ 3 ~ h ~ 6 o) ~ b ~ (c ~ 4 ~ h ~ 8 o) where r ^ 13 ^ is a linear or branched divalent hydrocarbon radical having the structure: -ch ~ 2 -ch (r ^ 15 ^) (r ^ 16 ^) ~ d-o- where r ^ 15 ^ is h or methyl; R 16 is a divalent alkyl radical of 1 to 6 carbons wherein the subscript d may be 0 or 1; R ^ 14 ^ is selected from the group consisting of h, monovalent hydrocarbon radicals of 1 to 6 carbon atoms and acetyl where subscripts a, b and c are zero or positive and satisfy the following relationships: 2 <;sym>; a + b + c <; sym>; 20 with <;sym>; 2 er ^ 5 ^ er ^ 6 ^ are each independently selected from the group of monovalent hydrocarbon radicals having from 1 to 6 carbon atoms or exhibiting hydrolysis resistance over a wide range of ph.composição agrícola, composição cosmética, composição para cuidados domésticos, emulsões aquosas e não aquosas das mesmas e composição de revestimento. composições compreendendo composições de tensoativo de dissiloxano compreendendo uma composição de silic
