Zusammenfassung:A fabric care formulation is provided, comprising: a liquid carrier; and a plurality of composite opacifier particles, wherein the composite opacifier particles comprise metal oxide particles that are partially or completely encapsulated by a wax; wherein the metal oxide particles are selected from the group consisting of zinc oxide, titanium oxide and mixtures thereof; wherein the metal oxide particles have a z average particle size of >100 nm as measured by dynamic light scattering; wherein the wax has a melting point temperature of 45 to 110° C.; and wherein the composite opacifier particles have a z average particle size of >100 nm to 2,000 nm as measured by dynamic light scattering.
