Abstract: Organopolysiloxane copolymers having the formula are useful in treating fibrous substances, particularly textile fabrics, to produce a laundering-resistant soft hand.

Abstract: Siloxane copolymers producible by (a) reacting organopolysiloxanes (1) having a Si-bound hydrogen atom with linear oligomeric or polymeric compounds (2) of the general formula R1-(A-CnH2n)m-A1-H (I), (b) reacting the resultant H-A1 group-bearing intermediates (4) with organic compounds (5) having at least two isocyanate groups in the presence of further organic compounds (6) and (7) which are reactive toward isocyanate groups, wherein the compounds (6) contain at least one tertiary amine group and the compounds (7) can be eliminated from the siloxane copolymer in a temperature range from 50° C. to 250° C., wherein free isocyanate groups are formed in the siloxane copolymer, and (c) partially or completely quaternizing the amine-containing intermediates (8) from step (b) with an alkylating agent (9).

Abstract: A description if given of novel siloxane copolymers producible by (a) reacting in a first step organopolysiloxanes (1) which comprise per molecule at least one Si-bound hydrogen atom with substantially linear oligomeric or polymeric compounds (2) of the general formula R1-(A-CnH2n)m-A1-H (I), wherein R1 is a monovalent substituted or unsubstituted hydrocarbon moiety to which Si—H groups can be added in a hydrosilylation reaction, A is a divalent, polar organic moiety selected from the group —O—, —C(O)—O—, —O—C(O)—, —O—C(O)—O—, —C(O)—NH—, —NH—C(O)—, urethane moiety and urea moiety, A1 is a divalent, polar organic moiety selected from the group —O—, —NH— and —NR?— (wherein R? is a monovalent hydrocarbon moiety having 1 to 18 carbon atoms), n is an integer from 1 to 20 and m is O or a positive integer, (b) reacting in a second step the resultant H-A1 group-bearing intermediates (4) with organic compounds (5) which comprise per molecule at least two isocyanate groups, wherein the reaction takes place in the prese

Abstract: A pigment printing dyestuff composition for textile finishing comprises a cyclodextrin or cyclodextrin derivative in turn capable of including a scent as a guest molecule.

Abstract: A process is disclosed for stabilizing and dispersing vegetable oils which contain polyunsaturated fatty acid radicals by means of .gamma.-cyclodextrin, as well as the thus obtained complexes and their use. In this process for stabilizing vegetable oils having a high proportion of triacylglycerines and containing polyunsaturated fatty acids, cyclodextrin is mixed with vegetable oil and so a cyclodextrin/vegetable oil complex is formed. This process is characterized in that .gamma.-cyclodextrin is used to form complexes with vegetable oils.

Abstract: Complexes of .gamma.-cyclodextrin and retinol or retinol derivatives, along with processes for their preparation and compositions for their use. The complexes are useful in cosmetic formulations and in pharmaceutical formulations.
