Patent ID: 7473673

Claim:
A bar composition consisting of: (a) 5 to 90% by wt. of a surfactant system comprising a surfactant or surfactants selected from the group consisting of soap, alkyl sulphate and mixtures thereof, (b) 20 to 80% by wt. water-soluble or water insoluble hydrophilic structurant comprising sugar; (c) 0.1 to 20% by wt. of deposition enhancement system comprising 0.1 to 1% of a cationic polymer having charge density of ≧6.2 Meg/gm and 0.1 to 30% by wt, anionic surfactant selected from the group consisting of C 10 -C 24 fatty acid soap, alkyl sulfate and mixtures thereof; wherein molecule or molecules forming said deposition enhancement system form an individual coating in situ on about 50% to 100% of flat platy titania coated mica optical modifier particles in said composition, thereby allowing said optical modifier particles to attach individually on foam bubbles formed during rinse dilution or use and to deposit said particles from a foam/particle structure also formed during said rinse; (d) 0 to 10% by wt. oil/emollient at least some of which emollient molecules may be present as part of the in-situ coating deposition system; (e) 1 to 5% hydrophilic emollient selected from the group consisting of glycerin, polyalkylene glycol, trialkanolamine, urea and mixtures thereof; (f) 0.1 to 15% by wt. solid particulate titania coated mica optical modifier particles, wherein said modifier particles comprises flat platy particulates having D50 size range of 6 to 70 micrometer and thickness to 50 to 1000 nanometer, said particles being the substrate for the in-situ deposition enhancement system of (c); and (g) 1 to 20% water, wherein from at least 50% to 100% of platy particles present in the composition deposit onto skin or other substrate from the foam portion of a foam portion and liquor portion generated during rinse.
