Cleaning compositions
A liquid cleaning composition containing alkyl polyglycoside surfactants, an alkylated vegetable oil, water and a sodium-containing base provides excellent cleaning soil removal capabilities. The carbon materials from which it is manufactured are all renewable, and the composition is readily biodegradable.
1. A liquid cleaning composition consisting of:
a nonionic surfactant system;
an alkylated vegetable oil;
a sodium-containing base; and
water.
2. The liquid cleaning composition of claim 1 , wherein the nonionic surfactant system comprises alkyl polyglycosides.
3. The liquid cleaning composition of claim 1 , wherein the nonionic surfactant system comprises: (a) short chain alkyl polyglycosides having an alkyl chain length of from 8 to 10 carbon atoms; and (b) long chain alkyl polyglycosides having an alkyl chain length of from 12 to 14 carbon atoms.
4. The liquid cleaning composition of claim 3 , wherein the short chain and long chain alkyl polyglycosides have a degree of polymerization between 1 and about 5.
5. The liquid cleaning composition of claim 4 , wherein the short chain and the long chain alkyl polyglycosides comprise alkly polyglucosides.
6. The liquid cleaning composition of claim 1 , wherein the alkylated vegetable oil comprises an alkyl soyate.
7. The liquid cleaning composition of claim 1 , wherein the alkylated vegetable oil is selected from the group consisting of methyl soyate, ethyl soyate and propyl soyate.
8. The liquid cleaning composition of claim 1 , wherein the alkylated vegetable oil comprises methyl soyate.
9. The liquid cleaning composition of claim 1 , wherein the sodium-containing base comprises sodium carbonate.
10. A liquid cleaning composition consisting of:
a) from 20% to 60% by weight, of alkyl polyglycosides containing: (i) at least one short chain alkyl polyglycoside having a chain length of from 8 to 10 carbon atoms; and (ii) at least one long chain alkyl polyglycoside having a chain length of from 12 to 14 carbon atoms;
(b) from 1% to 15% by weight of an alkylated vegetable oil;
(c) from 1% to 15% by weight of a sodium base selected from sodium hydroxide, sodium carbonate, and mixtures thereof; and
(d) the balance water and other adjunct ingredients.
11. The liquid cleaning composition of claim 10 , wherein the short chain and the long chain alkyl polyglycosides comprise alkyl polyglucosides.
12. The liquid cleaning composition of claim 10 , wherein the alkylated vegetable oil comprises an alkyl soyate.
13. The liquid cleaning composition of claim 10 , wherein the alkylated vegetable oil comprises methyl soyate.
14. The liquid cleaning composition of claim 10 , wherein the sodium-containing base comprises sodium carbonate.
15. A process for making a liquid cleaning composition, the process comprising:
preparing an alkaline aqueous solution comprising water and a sodium-containing base; and
mixing the alkaline aqueous solution with at least one alkyl polyglycoside and at least one alkylated vegetable oil such that the resulting liquid cleaning composition consists of 20% to 60% by weight alkyl polyglycosides, 1% to 15% by weight alkylated vegetable oil, 1% to 15% by weight sodium-containing base, and the balance water and other adjunct ingredients.
16. The process of claim 15 , wherein the sodium-containing base comprises sodium carbonate.
17. The process of claim 15 , wherein the at least one alkyl polyglycoside comprises at least one short chain alkyl polyglucoside having a chain length of from 8 to 10 carbon atoms, and at least one long chain alkyl polyglucoside having a chain length of from 12 to 14 carbon atoms.
18. The process of claim 15 , wherein the alkylated vegetable oil comprises an alkyl soyate.
19. The process of claim 15 , wherein the alkylated vegetable oil comprises methyl soyate, and the sodium-containing base comprises sodium carbonate.
