Abstract

A process for handwashing socks or stockings which utilizes a detergent composition having, as effective components, an ethylene oxide adduct of a secondary alcohol, a sulfuric ester salt of an ethylene oxide adduct of a secondary alcohol, and an amphoteric surfactant is described.

Claims

1. A process for washing socks or stockings which consists essentially of immersing socks or stockings in an aqueous solution of a detergent composition and washing same by hand, said detergent composition consisting essentially of, as effective components, an ethylene oxide adduct of one mole of a mixture of C₁₁ -C₁₅ secondary alcohols and 3, 5, 9 or 12 moles of ethylene oxide, or one mole of a mixture of C₁₄ -C₁₅ secondary alcohols and 3, 5 or 10 moles of ethylene oxide and mixtures thereof, and an ethoxy sulfate salt of an ethylene oxide adduct of a mixture of one mole of C₁₁ -C₁₅ or C₁₄ -C₁₅ secondary alcohols and 3 moles of ethylene oxide, and mixtures thereof, and an amphoteric surfactant selected from the group consisting of alkyldiaminoethylglycines wherein the alkyl group has from 8 to 18 carbon atoms, alkyldimethylbetaines wherein the alkyl group has from 12 to 18 carbon atoms and cyclic imidinium amphoteric surfactants of the formula:

##STR4## wherein R¹ is an aliphatic hydrocarbon group of 7 to 17 carbon atoms, R² is a member selected from the group consisting of hydroxyl, ##STR5## C₁₂ H₂₅ OSO₃, and C₁₃ H₂₇ (OC₂ H₄)₃ OSO₃, R³ is a member selected from the group consisting of CH₂ COOH, CH₂ COONa, and ##STR6## R⁴ is a member selected from the group consisting of hydrogen, alkali metals, CH₂ COOH, CH₂ COONa and CH₂ COOK;

the weight ratio of the ethylene oxide adduct of a secondary alcohol to the surfuric ester salt of an ethylene oxide adduct of a secondary alcohol being in the range of from 95;

5 to 30;

70 and the weight ratio of the total of the ethylene oxide adduct of a secondary alcohol and the sulfuric ester salt of an ethylene oxide adduct of a secondary alcohol to the amphoteric surfactant being from 98;

2 to 80;

20.

2. The process according to claim 1, wherein the ethylene oxide adduct is 1 mole of a mixture of C₁₁ -C₁₅ secondary alcohols having 3, 5, 9 or 12 moles of ethylene oxide.

3. The process according to claim 1 wherein the ethylene oxide adduct is 1 mole of a mixture of C₁₄ -C₁₅ secondary alcohols having 3, 5, or 10 moles of ethylene oxide.

4. The process according to claim 1 wherein the weight ratio of the ethylene oxide adduct of a secondary alcohol to the sulfuric ester salt of an ethylene oxide adduct of a secondary alcohol is in the range of from 80:

20 to 50;

50.

5. The process according to claim 1 wherein the weight ratio of the total of the ethylene oxide adduct of a secondary alcohol and the sulfuric ester salt of an ethylene oxide adduct of a secondary alcohol to the amphoteric surfactant is in the range of from 97:

3 to 85;

15.

6. The process according to claim 1 wherein the sulfuric ester salt is selected from the group consisting of sodium, ammonium, monoethanolamine, diethanolamine, and triethanolamine salts.

7. The process according to claim 6 wherein the sulfuric ester salt is selected from the group consisting of sodium, triethanolamine and ammonium salts of an ethoxy sulfate of an adduct of 1 mole of a mixture of C₁₄ -C₁₅ secondary alcohols having 3 moles of ethylene oxide.
