Abstract
Abstract A fabric softening composition which comprises: (i) an ester-linked quaternary ammonium material of the formula: wherein each R 1 group is independently selected from C 1 -4 alkyl, alkenyl or hydroxyalkyl groups; each R 2 group is independently selected from C8-28 alkyl or alkenyl groups; T is and n is an integer from 0-5; and (ii) an extender material selected from: (a) quaternary ammonium compounds, comprising one long alkyl or alkenyl group; (b) predominantly linear nonionic materials; or (c) mixtures thereof; said composition being obtainable by heating a mixture comprising the materials (i) and (ii) to a temperature of above 40°C, followed by dispersing the mix into water.

123 words
A fabric softening composition comprising (i) at least 1 % by weight of an ester-linked quaternary ammonium material of the formula: wherein each R 1 group is independently selected from C 1-4 alkyl, alkenyl or hydroxyalkyl groups; each R 2 group is independently selected from C 8 - 28 alkyl or alkenyl groups; T is and n is an integer from 0-5; and (ii) at least 0.1% by weight of an extender material selected from: (a) quaternary ammonium compounds, comprising one long alkyl or alkenyl group; (b) predominantly linear nonionic mateials; or (c) mixtures thereof said composition being obtainable by heating a mixture comprising the materials (i) and (ii) to a temperature of above 40 C, followed by dispersing the mix into water.
Claim 2
Dependent Claim
123 words
A fabric softening composition comprising (i) at least 1 % by weight of an ester-linked quaternary ammonium material of the formula: wherein each R 1 group is independently selected from C 1-4 alkyl, alkenyl or hydroxyalkyl groups; each R 2 group is independently selected from C 8 - 28 alkyl or alkenyl groups; T is and n is an integer from 0-5; and (ii) at least 0.1% by weight of an extender material selected from: (a) quaternary ammonium compounds, comprising one long alkyl or alkenyl group; (b) predominantly linear nonionic mateials; or (c) mixtures thereof said composition being obtainable by heating a mixture comprising the materials (i) and (ii) to a temperature of above 40 C, followed by dispersing the mix into water.
Claim 3
Dependent Claim
109 words
A fabric softening composition which comprises a dispersion in water of: (i) at least 1 % by weight of an ester-linked quaternary ammonium material of the formula: wherein each R 1 group is independently selected from C 1 -4 alkyl, alkenyl or hydroxyalkyl groups; each R 2 group is independently selected from C8-28 alkyl or alkenyl groups; T is and n is an integer from 0-5; and (ii) at least 0.1% by weight of an extender material selected from: (a) quaternary ammonium compounds, comprising one long alkyl or alkenyl group; (b) predominantly linear nonionic materials; or (c) mixtures thereof; said dispersion having mean partice diameter of less than 10µm.
Claim 4
Dependent Claim
