    • [0095] There is provided herein a demulsifying composition comprising (a) an emulsion; and (b) a demulsifying-effective amount of at least one polyorganosiloxane compound having the general formula (I): M 1 aM 2 bD 1 cD 2 d T 1 eT 2 fQg (I) wherein: M 1 = R 1 R 2 R 3 SiO 1/2 , M 2 = R 4 R 5 RLSiO 1/2 ,D 1 = R 6 R 7 Si0 2/2 ,D 2 = R 8 R L Si0 2/2 , T 1 = R 9 Si0 3/2 ,T 2 = R L Si0 3/2 ,Q = Si0 4/2 , where R 1 , R 2 , R 3 , R 4 , R 5 , R 6 , R 7 , R 8 and R 9 are each independently chosen from monovalent alkyl, aryl or aralkyl hydrocarbon radicals containing 1 to 60 carbon atoms, optionally containing at least one heteroatom, or chosen from R p ; R P is a monovalent polyether radical independently of the general formula (II): - (C n H 2n )-0-(C 2 H 4 0) o- (C 3 H 6 O) p- (C 4 H 8 O) q -R 10 (II) where R10 is hydrogen or a monovalent alkyl radical containing from 1 to about 20 carbon atoms or an acyl group; subscripts a, b, c, d, e, f and g are zero or positive integers, subject to the limitations: 2≤ a+b+c+d+e+f+g≤500, b+d+f >1 and a+b=2+e+f+2g; subscript n is 2 to about 10; subscript o is 0 to about 200; subscript p is 0 to about 200; subscript q is 0 to about 200; and, subject to the limitation o+p+q≥1; R L is a monovalent radical independently chosen from the general formula (III): -X-0-(C 2 H 4 O)-(C 3 H 6 O) s- (C 4 H 8 O) t- {C(0)C u H 2u O} v -R 11 (III) where R 11 is hydrogen or monovalent alkyl radical containing from 1 to about 20 carbon atoms or an acyl group, and where X is a linear, branched or cyclic divalent hydrocarbon or aralkyl radical containing from 21 to about 20 carbon atoms, optionally containing at least one heteroatom; subscript r is 0 to about 200; subscript s is 0 to about 200; subscript t is 0 to about 200; subscript u is 1 to about 20; subscript v is 1 to about 200, and subject to the limitation if r+s+t is equal to zero then the polyorganosiloxane contains at least one R P radical. There is also provided herein a method for separating emulsions comprising combining the components of the demulsification composition into a mixture; allowing the mixture to separate into at least two phases and separating said at least two phases from each other.
