Abstract

The present invention relates generally to compositions and methods of use for an automotive protectant composition and/or automotive cleaning composition. The protectant composition and/or cleaning composition includes silicone, organic solvent, rheology modifier and water. The composition also optionally includes other components. The weight ratio of the silicon to the organic solvent is at least 0.5:1 and generally no more than 3:1. The organic solvent generally is or includes mineral oil.

Claims

1. A silicone based automotive protectant composition comprising:

a. at least 0.5 weight percent and up to 10 weight percent silicone;

b. at least 0.1 weight percent and up to 10 weight percent of an organic solvent comprising oil selected from the group consisting of;

a mineral oil, a natural oil, and combinations or mixtures thereof, wherein said organic solvent includes more than 60 weight percent mineral oil;

c. from 0.01 to 3 weight percent of a rheology modifier; and

d. from 60 to 98 weight percent water;

wherein a weight ratio of said silicone to said organic solvent is 0.5-3;

1, wherein said protectant composition is sprayable or pumpable and has a viscosity of 1600-3100 cSt (25°

C.), and wherein no surfactant is included in said protectant composition.

2. The protectant composition as defined in claim 1, wherein said weight ratio of said silicone to said organic solvent is over 0.5:

1; and

up to 2;

1.

3. The protectant composition as defined in claim 2, wherein said weight ratio of said silicone to said organic solvent is 0.75-1.5:

1.

4. The protectant composition as defined in claim 1, comprising by weight percent:

5. The protectant composition as defined in claim 1, comprising by weight percent:

6. The protectant composition of claim 1 wherein the composition provides similar or higher gloss, shine, spreadability and/or protection to a substrate surface in comparison to a protectant composition having a weight percent silicone greater than 10 weight percent, and a surfactant present.

7. The protectant composition of claim 1 which protects a substrate surface from heat damage and/or fading to sun exposure.

8. The protectant composition of claim 1 which protects a substrate surface from damaging effects of UV rays, sunlight, heat and moisture.

9. The protectant composition as defined in claim 1, wherein said organic solvent includes more than 90 weight percent mineral oil.

10. The protectant composition as defined in claim 1, further comprising at least one ingredient selected from the group consisting of a rheology modifying agent, buffering or pH adjusting agent, biocide or preservative, opacifier, fragrance, and combinations thereof

11. The protectant composition as defined in claim 10, wherein said at least one ingredient comprises from 0.0001 to 5 weight percent of the protectant composition.

12. A silicone based automotive protectant composition comprising:

a. over 0.5 weight percent and up to 10 weight percent silicone;

b. at least 0.1 weight percent and up to 10 weight percent of an organic solvent, said organic solvent comprising at least 80 weight percent mineral oil;

c. from 0.01 to 3 weight percent of a rheology modifier; and

d. from 70 to 98 weight percent water;

wherein a weight ratio of said silicone to said organic solvent is 0.6-2;

1, wherein said protectant composition is spra able or pumpable and has a viscosity of 1600-3100 cSt (25°

C.), and wherein no surfactant is included in said protectant composition.

13. The protectant composition as defined in claim 12, wherein said weight ratio of said silicone to said organic solvent is 0.75-1.5:

1.

14. The protectant composition as defined in claim 12, wherein said organic solvent includes more than 90 weight percent mineral oil.

15. A sprayable silicone based automotive protectant composition comprising:

a. over 0.8 weight percent and up to 10 weight percent silicone;

b. at least 0.1 weight percent and up to less than 10 weight percent of an organic solvent, said organic solvent including at least 90 weight percent mineral oil, natural oil or a combination thereof;

c. from 0.01 to 3 weight percent of a rheology modifier; and

d. from 70 to 98 weight percent water;

wherein a weight ratio of said silicone to said organic solvent is 0.75-1.8;

1, wherein said protectant composition is sprayable or pumpable and has a viscosity of 1600-3100 cSt (25°

C.), and wherein no surfactant is included in said protectant composition.
