Abstract

A cleaner composition includes: a saturated aliphatic hydrocarbon (A); an anionic surfactant (B); a nonionic surfactant (C); and water (D). The cleaner composition contains the saturated aliphatic hydrocarbon (A) in a proportion of 60.0% by mass to 85.0% by mass, the anionic surfactant (B) in a proportion of 8.0% by mass to 15.0% by mass, the nonionic surfactant (C) in a proportion of 2.0% by mass to 5.0% by mass, and the water (D) in a proportion of 1.0% by mass to 20.0% by mass, forms a W/O microemulsion or a solubilized W/O emulsion, and has a volume resistivity of 1×10 9 Ω·cm or less.

First claim

The invention claimed is:

1. A cleaner composition comprising:
a saturated aliphatic hydrocarbon (A);
an anionic surfactant (B);
a nonionic surfactant (C); and
water (D),
wherein the cleaner composition
contains the saturated aliphatic hydrocarbon (A) in a proportion of 60.0% by mass to 85.0% by mass, the anionic surfactant (B) in a proportion of 8.0% by mass to 15.0% by mass, the nonionic surfactant (C) in a proportion of 2.0% by mass to 5.0% by mass, and the water (D) in a proportion of 1.0% by mass to 20.0% by mass,
forms a W/O microemulsion or a solubilized W/O emulsion, and
has a volume resistivity of 1×10 9 Ω·cm or less, and
wherein the anionic surfactant (B) is a dialkyl sulfosuccinate, and the nonionic surfactant (C) is a sorbitan fatty acid ester.

2. The cleaner composition according to claim 1 , wherein the saturated aliphatic hydrocarbon (A) is a C 9-13 paraffinic hydrocarbon.

3. The cleaner composition according to claim 1 , wherein the anionic surfactant (B) and the nonionic surfactant (C) are contained in a proportion of 10.0% by mass to 20.0% by mass in total, and the anionic surfactant (B) and the nonionic surfactant (C) are compounded in a ratio (mass ratio) of 2.0 to 5.0:1.

4. The cleaner composition according to claim 1 , wherein the cleaner composition has a saturated water content, measured through turbidity, of 10% by mass or more.

5. The cleaner composition according to claim 1 , wherein the cleaner composition contains no polar solvent.

6. The cleaner composition according to claim 2 , wherein the anionic surfactant (B) and the nonionic surfactant (C) are contained in a proportion of 10.0% by mass to 20.0% by mass in total, and the anionic surfactant (B) and the nonionic surfactant (C) are compounded in a ratio (mass ratio) of 2.0 to 5.0:1.

7. The cleaner composition according to claim 2 , wherein the cleaner composition has a saturated water content, measured through turbidity, of 10% by mass or more.

8. The cleaner composition according to claim 2 , wherein the cleaner composition contains no polar solvent.

9. The cleaner composition according to claim 3 , wherein the cleaner composition has a saturated water content, measured through turbidity, of 10% by mass or more.

10. The cleaner composition according to claim 3 , wherein the cleaner composition contains no polar solvent.

11. The cleaner composition according to claim 4 , wherein the cleaner composition contains no polar solvent.
