Abstract
Improved anti-static compositions comprising an electrically conductive metal salt dispersed in a water-insoluble quaternary compound are employed in improved detergent compositions. Detergent-compatible fabric softeners, and detergent compositions containing same, comprising a smectite clay softener and the improved anti-static compositions are provided.
Claims39
A fabric softener and anti-static composition especially adapted for use in combination with anionic, zwitterionic and ampholytic surfactants, comprising:
- a. from about 10% to about 99% by weight of a softening component comprising a smectite clay having an ultimate particle diameter of from about 150 anstroms to about 4500 angstroms;
- and
- b. from about 1% to about 99% by weight of an anti-static component comprising a mixture of a quaternary compound and an electrically conductive salt wherein the electrically conductive salt is uniformly dispersed in the quaternary compound wherein:
- i. the quaternary compound has the formula ##EQU2## wherein M is nitrogen or phosphorus, X is any anion, R.sup.1 is a hydrocarbyl moiety, R.sup.2 is hydrogen or a hydrocarbyl moiety, the total carbon content of R.sup.1 + R.sup.2 being at least 22 carbon atoms, and R.sup.3 and R.sup.4 are each hydrogen or hydrocarbyl moieties;
- and
- ii. the electrically conductive salt is selected from the group consisting of aluminum salts and lithium salts,
- at a weight ratio of quaternary compound:salt in said anti-static component in the range of 1000:1 to 1:5.
A detergent composition adapted to imparting an anti-static effect to fabrics in an aqueous laundering medium, comprising:
- a. from about 1% to about 99.9% by weight of a water-soluble detergent component selected from the group consisting of anionic, nonionic, amphoteric and zwitterionic surfactants;
- and
- b. from about 0.1% to about 20% by weight of an anti-static component comprising a mixture of a quaternary compound and an electrically conductive salt wherein the electrically conductive salt is uniformly dispersed in the quaternary compound wherein:
- i. the quaternary compound has the formula ##EQU3## wherein M is nitrogen or phosphorus, X is any anion, R.sup.1 is a hydrocarbyl moiety, R.sup.2 is hydrogen or a hydrocarbyl moiety, the total carbon content of R.sup.1 + R.sup.2 being at least 22 carbon atoms, and R.sup.3 and R.sup.4 are each hydrogen or hydrocarbyl moieties;
- and
- ii. the electrically conductive salt is selected from the group consisting of aluminum salts and lithium salts,
- at a weight ratio of quaternary compound:salt in said anti-static component in the range of 1000:1 to 1:5.
A detergent composition adapted to imparting a softening and anti-static effect to fabrics in an aqueous laundering medium, comprising:
- a. from about 5% to about 50% by weight of a water-soluble detergent component selected from the group consisting of anionic, nonionic, amphoteric and zwitterionic surfactants;
- b. from about 1% to about 40% by weight of a softening component comprising a smectite clay having an ultimate particle diameter of from about 150 angstroms to about 4500 angstroms;
- and
- c. from about 0.1% to about 20% by weight of an anti-static component comprising a mixture of a quaternary compound and an electrically conductive salt wherein the electrically conductive salt is uniformly dispersed in the quaternary compound wherein:
- i. the quaternary compound has the formula ##EQU4## wherein M is nitrogen or phosphorus, X is any anion, R.sup.1 is a hydrocarbyl moiety, R.sup.2 is hydrogen or a hydrocarbyl moiety, the total carbon content of R.sup.1 + R.sup.2 being at least 22 carbon atoms, and R.sup.3 and R.sup.4 are each hydrogen or hydrocarbyl moieties;
- and
- ii. the electrically conductive salt is selected from the group consisting of aluminum salts and lithium salts,
- at a weight ratio of quaternary compound:salt in said anti-static component in the range of 1000:1 to 1:5.
