Claims16
A water-in-oil detergent emulsion to be applied to fabrics as a laundry pre-spotting composition comprising:
- (a) from about 1 to about 30% by weight of a salt selected from the group consisting of citrates, gluconates, borates, silicates, phosphates, chlorides, carbonates and mixtures thereof;
- (b) from about 1 to about 35% by weight of a surfactant mixture of (i) about 0.5 to about 5% by weight of a sorbitan nonionic surfactant selected from the group consisting of sorbitan monolaurate, sorbitan monooleate, sorbitan trioleate and mixtures thereof;
- (ii) from about 0.5 to about 30% of at least one other nonionic surfactant;
- and (iii) from about 0.5 to 3.0% by weight, of an ethoxylated sorbitan nonionic surfactant, said mixture having an HLB of from 8.5 to 10.5;
- (c) from about 5 to about 60% by weight of a solvent selected from the group consisting of isoparaffinic hydrocarbons having a boiling range of from 98.degree.-210.degree. C., low odor petroleum solvents having a boiling range of from 195.degree.-250.degree. C., kerosene, d-Limonene and mixtures thereof;
- and
- (d) the balance water.
A water-in-oil detergent emulsion to be applied to fabrics as a laundry pre-treating composition comprising:
- (a) from about 1 to 15% by weight of a salt selected from the group consisting of citrates, gluconates, borates, silicates, phosphates, chlorides, carbonates and mixtures thereof;
- (b) from about 3 to 25% by weight of a mixture of:
- (i) from about 0.5 to about 2% by weight of a sorbitan nonionic surfactant selected from the group consisting of sorbitan monolaurate, sorbitan monooleate, sorbitan trioleate and mixtures thereof;
- (ii) from about 2.0 to 23% by weight of a nonionic selected from the group consisting of ethoxylated nonylphenols, ethoxylated octaphenols, ethoxylated secondary alcohols, ethoxylated primary alcohols, ethylene oxide polymers, ethylene oxide propylene oxide copolymers and mixtures thereof;
- and
- (iii) from about 0.5 to about 2% by weight of an ethoxylated sorbitan nonionic selected from the group consisting of ethoxylated sorbitan monolaurate with 20 moles ethylene oxide, ethoxylated sorbitan monopalmitate with 20 moles ethylene oxide, ethoxylated sorbitan monostearate with 20 moles ethylene oxide, ethoxylated sorbitan monoleate with 20 moles ethylene oxide and mixtures thereof;
- the nonionic mixture having an HLB of 8.5 to 10.5;
- (c) from about 5 to about 35% by weight of a solvent selected from the group consisting of isoparaffinic hydrocarbons having a boiling range of from 98.degree.-210.degree. C., low odor petroleum solvents having a boiling range of from 195.degree.-250.degree. C., kerosene, d-Limonene and mixtures thereof;
- and
- (d) the balance water.
A water-in-oil detergent emulsion to be applied to fabrics as a laundry pre-spotting composition contained in a pressurized aerosol container comprising from 95 to 80% by weight of a composition comprising:
- (a) from about 1 to about 30% by weight of a salt selected from the group consisting of citrates, gluconates, borates, silicates, phosphates, chlorides, carbonates and mixtures thereof;
- (c) from about 1 to about 35% by weight of a surfactant mixture of (i) about 0.5 to about 5% by weight of a sorbitan nonionic surfactant selected from the group consisting of sorbitan monolaurate, sorbitan monooleate, sorbitan trioleate and mixtures thereof;
- and (ii) from about 0.5 to about 30% of at least one other nonionic surfactant, said mixture having an HLB of from 8.5 to 10.5;
- (c) from about 5 to about 60% by weight of a solvent selected from the group consisting of isoparaffinic hydrocarbons having a boiling range of from 98.degree.-210.degree. C., low odor petroleum solvents having a boiling range of from 195.degree.-250.degree. C., kerosene, d-Limonene and mixtures thereof;
- and
- (d) the balance water and from 5 to 20% by weight of a propellent.
