Abstract:
1. A method for uniform and efficient deposition of fabric care active onto a fabric article in a non-aqueous fabric treatment process comprising the steps of: (a) obtaining a delivery system comprising: from about 90% to about 99.99% by weight of the delivery system of a first phase comprising a silicone lipophilic fluid; a second phase comprising water as a carrier and a fabric care active selected from the group consisting of soil release polymers, enzymes, perfumes, softening agents, finishing polymers, dye transfer inhibiting agents, dye fixatives, UV protection agents, wrinkle reducing/removing agents, fabric rebuild agents, fiber repair agents, perfume release and/or delivery agents, shape retention agents, fabric and/or soil targeting agents, antibacterial agents, anti-discoloring agents, hydrophobic finishing agents UV blockers, brighteners, pigments, pill prevention agents, temperature control technology, skin care lotions, fire retardants, and mixtures thereof, the carrier being substantially insoluble in the lipophilic fluid; and an effective amount of an emulsifying agent sufficient to emulsify the composition such that the second phase forms discrete droplets; (b) contacting a fabric article with the delivery system to deposit on said article from 0.001% to about 3% of said active, based on the dry weight of said article; (c) removing at least a portion of the lipophilic fluid from said fabric article by a process selected from spinning, squeezing, wringing and combinations thereof; and (d) heating said fabric article from step (c) to a temperature from about 90° C. to about 200° C., said temperature being at or above the melting temperature of the fabric care active; wherein the second phase is in the form of droplets having a median particle diameter (χ
