Abstract

A composition suitable for cleaning hard surfaces comprising a natural oil solvent and a natural oil thickener is provided.

Claims (36)

1. A composition suitable for cleaning hard surfaces comprising a natural oil solvent and a natural oil thickener wherein said natural oil thickener comprises at least one material selected from the group consisting of:

wherein:

R x and R y are the groups necessary to represent a natural oil selected from the group consisting of soybean oil, linseed oil, safflower oil, sunflower oil, avocado oil, rapeseed oil, castor oil, tall oil, rosin oil and tung oil;

R 1 and R 2 independently represent a combination of an alkyl of 1-5 carbons either unsubstituted or substituted with an alkyl of 1-5 carbons; an alkenyl of 1-5 carbons either unsubstituted or substituted with an alkyl of 1-5 carbons; or

—(CH 2 CHR 5 O) n−1 (CH 2 CHR 5 )— in sequence wherein each R 5 independently is —H or —CH 3 and n is an integer of 1-100; or some combination thereof;

R 3 represents —(CH 2 CHR 5 O) n−1 (CH 2 CHR 5 )— in sequence wherein each R 5 independently is —H or —CH 3 and n is an integer of 2-100 wherein at least one R 5 is —H; and

wherein said natural oil solvent is selected from the group consisting of limonene, soy methyl ester, pinene, tall oil alkyl ester, linseed oil alkyl ester, tung oil, esters derived from tung oil.

2. The composition suitable for cleaning hard surfaces of claim 1 wherein n is 10-70.

3. A composition suitable for cleaning hard surfaces comprising a natural oil solvent and a natural oil thickener wherein said natural oil thickener comprises at least one material selected from the group consisting of:

wherein:

R x and R y are the groups necessary to represent a natural oil;

R 1 , R 2 and R 3 independently represent an alkyl of 1-5 carbons either unsubstituted or substituted with an alkyl of 1-5 carbons; an alkenyl of 1-5 carbons either unsubstituted or substituted with an alkyl of 1-5 carbons; or —(CH 2 CHR 5 O) n−1 (CH 2 CHR 5 )— wherein each R 5 independently is —H or —CH 3 ; or some combination thereof wherein n is 10-100; and

wherein said natural oil solvent is selected from the group consisting of limonene, soy methyl ester, pinene, tall oil alkyl ester, linseed oil alkyl ester and tung oil.

4. The composition suitable for cleaning hard surfaces of claim 3 wherein n is 10-70.

5. A composition suitable for cleaning hard surfaces comprising a natural oil solvent and a natural oil thickener wherein said natural oil thickener comprises at least one material selected from the group consisting of:

wherein:

R x and R y are the groups necessary to represent a natural oil wherein said natural oil is a triglyceride oil selected from the group consisting of soybean oil, linseed oil, safflower oil, sunflower oil, avocado oil, rapeseed oil, castor oil, tall oil, rosin oil and tung oil;

R 1 and R 2 independently represent a combination of an alkyl of 1-5 carbons either unsubstituted or substituted with an alkyl of 1-5 carbons; an alkenyl of 1-5 carbons either unsubstituted or substituted with an alkyl of 1-5 carbons; or

—(CH 2 CHR 5 O) n−1 (CH 2 CHR 5 )— in sequence wherein each R 5 independently is —H or —CH 3 and n is an integer of 1-100; or some combination thereof; and

R 3 represents —(CH 2 CHR 5 O) n−1 (CH 2 CHR 5 )— in sequence wherein each R 5 independently is —H or —CH 3 and n is an integer of 2-100 wherein at least one R 5 is —H.

6. The composition suitable for cleaning hard surfaces of claim 5 wherein said natural oil is selected from the group consisting of soybean oil, linseed oil, rapeseed oil, castor oil, tall oil, rosin oil and tung oil.

7. The composition suitable for cleaning hard surfaces of claim 1 comprising 10 to 80 wt % said natural oil solvent.

8. The composition suitable for cleaning hard surfaces of claim 1 said composition having a viscosity of 400-10,000 cP.

9. The composition suitable for cleaning hard surfaces of claim 8 said composition having a viscosity of 1,400-8,100 cP.

10. The composition suitable for cleaning hard surfaces of claim 1 further comprising water.

11. The composition suitable for cleaning hard surfaces of claim 1 comprising 1-50 wt % water.

12. The composition suitable for cleaning hard surfaces of claim 11 said composition comprising 15-25 wt % water.

13. The composition suitable for cleaning hard surfaces of claim 1 wherein said composition further comprising a solvent.

14. The composition suitable for cleaning hard surfaces of claim 1 wherein said natural oil solvent is selected from the group consisting of D-limonene, soy methyl ester, pinene, tall oil methyl ester, linseed oil methyl ester and tung oil.

15. A composition suitable for cleaning hard surfaces comprising a natural oil solvent and a natural oil thickener wherein said natural oil thickener comprises at least one material selected from the group consisting of:

wherein:

R x and R y are the groups necessary to represent a natural oil selected from the group consisting of soybean oil, linseed oil, safflower oil, sunflower oil, avocado oil, rapeseed oil, castor oil, tall oil, rosin oil and tung oil;

R 1 and R 2 independently represent a combination of an alkyl of 1-5 carbons either unsubstituted or substituted with an alkyl of 1-5 carbons; an alkenyl of 1-5 carbons either unsubstituted or substituted with an alkyl of 1-5 carbons; or

—(CH 2 CHR 5 O) n−1 (CH2CHR 5 )— in sequence wherein each R 5 independently is —H or —CH 3 and n is an integer of 1-100; or some combination thereof;

R 3 represents —(CH 2 CHR 5 O) n−1 (CH 2 CHR 5 )— in sequence wherein each R 5 independently is —H or —CH 3 and n is an integer of 2-100 wherein at least one R 5 is —H; and

wherein said natural oil solvent is selected from the group consisting of limonene, soy methyl ester, pinene, tall oil alkyl ester, linseed oil alkyl ester and tung oil.
