Nonaqueous liquid detergent compositions
View Patent ↗A liquid detergent composition comprising: a) a surfactant, and b) a fatty acid salt containing a fatty acid chain having at least one carbon—carbon double bond, wherein said composition, when dissolved in water to a concentration of 5 wt %, has a pH of 6.8 or less.
1. A liquid detergent container comprising:
a) a surfactant,
b) a fatty acid salt containing a fatty acid chain having at least one carbon—carbon double bond, and
c) a total water content of less than 5 wt. %, wherein said composition, when dissolved an water to a concentration of 5 wt %, has a pH of 6.8 or less.
2. A container according to claim 1 , wherein the water-soluble container comprises poly (vinyl alcohol).
3. A container according to claim 1 wherein the surfactant is an anionic or nonionic surfactant.
4. A container according to claim 2 wherein the fatty acid salt is an alkali metal, alkaline earth metal, ammonium or amine salt.
5. A container according to claim 3 wherein the fatty acid salt is an alkanolamine salt.
6. A container according to claim 5 wherein the alkanolamine is monoethanolamine, triethanolamine or a mixture thereof.
7. A container according to claim 1 wherein the fatty acid salt contains from 10 to 22 carbon atoms in the fatty chain.
8. A container according to claim 7 wherein the fatty acid salt contains from 12 to 16 carbon stains in the fatty chain.
9. A container according to claim 1 wherein the fatty acid salt contains a fatty chain containing at least two carbon—carbon unsaturated bonds.
10. A container according to claim 1 wherein the fatty acid salt contains a linear fatty chain.
11. A container according to claim 1 wherein the fatty acid salt is a coconut fatty acid salt.
12. A container according to claim 1 wherein the pH is 6.5 or less.
13. A container according to claim 1 wherein the pH is at least 5.5.
14. A container according to claim 1 which comprises the surfactant in an amount of from 10 to 80 wt % relative to the total amount of the composition.
15. A container according to claim 1 which comprises the fatty acid salt in an amount of from 1 to 20 wt %.
16. A container according to claim 1 wherein the pH has been adjusted by the addition of an alkali containing the same cation as that of the fatty acid salt.
17. A container according to claim 1 wherein the pH has been adjusted by the addition of an alkanolamine.
18. A container according to claim 1 which is a laundry detergent composition.
19. A container according to claim 18 which is a fine-fabric detergent composition.
