Abstract

An aqueous cleaning composition including: a surfactant; a first compound that is immiscible with water and has Hansen solubility parameters of 10 MPa 0.5 ≤δ D ≤22 MPa 0.5 , 0≤δ P ≤14 MPa 0.5 , and 0≤δ H ≤14 MPa 0.5 ; and a second compound that is miscible with water and has Hansen solubility parameters of 10 MPa 0.5 ≤δ D ≤22 MPa 0.5 , 0≤δ P ≤10 MPa 0.5 , and 0≤δ H ≤14 MPa 0.5 , wherein the surfactant, the first compound, and the second compound are each independently included in an amount of 0.01 to 30 weight percent, based on a total weight of the cleaning composition.

First claim

What is claimed is:

1. An aqueous foaming cleaning composition comprising:
a nonionic alkoxylated surfactant that is a condensation product of an alcohol having a 2-ethyl hexyl group and 2 to 9 moles of ethylene oxide and propylene oxide per molecule of the alcohol, wherein the nonionic surfactant has a hydrophilic-lipophilic balance of 8.5 to 13.5;
a first compound comprising ethyl octanoate, butyl octanoate, ethyl decanoate, butyl decanoate, ethyl laurate, or a combination thereof; and
a second compound that is miscible with water and has Hansen solubility parameters of 14 MPa 0.5 ≤δ D ≤17 MPa 0.5 , 1≤δ P ≤7 MPa 0.5 , and 7≤δ H ≤12 MPa 0.5 ,
wherein the surfactant, the first compound, and the second compound are each independently included in an amount of 0.2 to 8 weight percent, based on a total weight of the cleaning composition.

2. The cleaning composition of claim 1 , wherein the surfactant has a hydrophilic-lipophilic balance of 9 to 13.

3. The cleaning composition of claim 1 , further comprising a substituted or unsubstituted terpene.

4. The cleaning composition of claim 1 , wherein the second compound comprises
a compound of Formula 2,
R 3 —(OC n H 2n ) z OX  (2)

wherein
R 3 is a substituted or unsubstituted C1 to C12 aliphatic group, a substituted or unsubstituted C6 to 12 aryl group, a group of the formula —C(═O)C 6 H 5 , or a group of the formula —C(═O)CH 3 ,
n is 2 to 12,
z is 1 to 4, and
X is —H, —CH 3 , —C(═O)CH 3 , or —C(═O)C 6 H 5 .

5. The cleaning composition of claim 1 , wherein the second compound comprises
a compound of Formula 2,
R 3 —(OC n H 2n ) z OX  (2)

wherein R 3 is a substituted or unsubstituted C1 to C12 aliphatic group, a substituted or unsubstituted C6 to C12 aryl group, a group of the formula —C(═O)C 6 H 5 , or a group of the formula —C(═O)CH 3 ,
n is 2 to 4,
z is 1 to 4, and
X is —H, —CH 3 , —C(═O)CH 3 , or —C(═O)C 6 H 5 .

6. The cleaning composition of claim 4 , wherein R 3 is an unsubstituted C2 to C6 alkyl group, n is 2 to 4, and z is 1 to 3.

7. The cleaning composition of claim 1 , wherein the first compound and the second compound each independently have a molecular weight of 80 to 750 Daltons.

8. A method of manufacturing an aqueous cleaning composition, the method comprising combining
a nonionic alkoxylated surfactant that is a condensation product of an alcohol having a 2-ethyl hexyl group and 2 to 9 moles of ethylene oxide and propylene oxide per molecule of the alcohol, wherein the nonionic surfactant has a hydrophilic-lipophilic balance of 8.5 to 13.5;
a first compound comprising ethyl octanoate, butyl octanoate, ethyl decanoate, butyl decanoate, ethyl laurate, or a combination thereof; and
a second compound that is water miscible and has Hansen solubility parameters of 14 MPa 0.5 ≤δ D ≤17 MPa 0.5 , 1≤δ P ≤7 MPa 0.5 , and 7≤δ H ≤12 MPa 0.5 ; to

manufacture the cleaning composition;
wherein the surfactant, the first compound, and the second compound are each independently included in an amount of 0.2 to 8 weight percent, based on a total weight of the cleaning composition.

9. A method of cleaning a surface comprising contacting the surface with the cleaning composition of claim 1 to form a foam having a foam stability from 0 to less than 30 seconds, as measured by the elapsed time to foam collapse; and removing soil and the cleaning composition from the surface.

10. The method of claim 9 , further comprising a substituted or unsubstituted terpene.

11. The cleaning composition of claim 1 , wherein the nonionic alkoxylated surfactant comprises a 2-ethyl hexanol ethylene oxide-propylene oxide non-ionic surfactant.

12. An aqueous foaming cleaning composition comprising:
a nonionic alkoxylated surfactant that is a condensation product of an alcohol having an alkyl group containing 6 to 20 carbon atoms and 2 to 9 moles of both of ethylene oxide and propylene oxide per molecule of the alcohol, wherein the nonionic surfactant has a hydrophilic-lipophilic balance of 8.5 to 13.5;
a first compound comprising ethyl octanoate, butyl octanoate, ethyl decanoate, butyl decanoate, ethyl laurate, or a combination thereof; and
a second compound that is miscible with water and has Hansen solubility parameters of 14 MPa 0.5 ≤δ D ≤17 MPa 0.5 , 1≤δ P ≤7 MPa 0.5 , and 7≤δ H ≤12 MPa 0.5 ,
