Claims
- 1. A particulate fabric softening additive for detergent compositions, comprising as the sole or major component, an intimate mixture of a water-soluble nonionic cellulose ether and an organic fabric softening agent selected from the group consisting of quaternary ammonium compounds, imidazolinium derivatives, fatty amines, soaps, organo-modified clays and mixtures thereof in the weight ratio of from 1:1 to 0.06:1, the cellulose ether being an alkyl hydroxyalkyl cellulose in which the alkyl group is selected from methyl and ethyl and the hydroxyalkyl group is selected from hydroxyethyl and hydroxypropyl, the cellulose ether having a degree of substitution of from 1.9 to 3 and from 0.9 to 2.0 alkyl groups and from 0.1 to 2. 0 hydroxyethyl groups per anhydroglucose ring and having an HLB of between 3.3 and 3.8, and a gel point of 33.degree. C. to 56.degree. C.
- 2. A softening additive according to claim 1, in which the cellulose ether has a degree of substitution of from about 1.9 to about 2.9 substituents per anhydroglucose ring.
- 3. A softening additive according to claim 1, in which the cellulose ether has a weight average degree of polymerisation of from about 50 to about 1,200.
- 4. A softening additive according to claim 1, in which the cellulose ether contains from 0.9 to 2.0 alkyl groups and from 0.1 to 2.0 hydroxyethyl groups per anhydroglucose ring.
- 5. A softening additive according to claim 1, in which the cellulose ether contains about 2.5 methyl groups per anhydroglucose ring.
- 6. A softening additive according to claim 1, in which the fabric softening agent is selected from quaternary ammonium compounds, imidazolinium derivatives, fatty amines, soaps organo-modified clays and mixtures thereof.
- 7. A fabric treatment composition comprising:
- (i) from 2% to 50% of a non-soap anionic detergent active material or a mixture thereof with other non-soap detergent active materials selected from the group consisting of nonionic, zwitterionic and amphoteric detergent active materials; and
- (ii) from 0.1% to 53% of the particulate fabric softening additive according to claim 1.
