Abstract
A fabric article treatment composition comprising a polar solvent and a hydrophobic surfactant, wherein the composition is miscible in a lipophilic fluid is provided.
Claims20
A method for removing and/or reducing a hydrophilic stain from a fabric article in need of treatment, the method comprising the steps of:
- (i) contacting the hydrophilic stain on a fabric article with a fabric article treatment composition thereby forming a pretreated fabric article;
- and
- (ii) contacting the pretreated fabric article with a lipophilic fluid such that the hydrophilic stain is removed and/or reduced;
- wherein the fabric article treatment composition is miscible with the lipophilic fluid and comprises:
- a) a polar solvent exhibiting at least one of the following Hansen solubility parameters:
- i) a fractional polar value (fP) of greater than 0.02;
- ii) a fractional hydrogen bonding value (fH) of greater than 0.10;
- and
- b) a hydrophobic surfactant.

- and
- (ii) contacting the pretreated fabric article with a lipophilic fluid such that the hydrophilic stain is removed and/or reduced;
- wherein the fabric article treatment composition is miscible with the lipophilic fluid and comprises:
- a) from about 50% to about 70% by weight of the fabric article treatment composition of a first polar solvent;
- b. from about 10% to about 30% by weight of the fabric article treatment composition of a second polar solvent different from the first;
- c. from about 10% to about 30% by weight of the fabric article treatment composition of a hydrophobic surfactant;
- and
- wherein the fabric article treatment composition is miscible in a lipophilic fluid.
