Aqueous compositions comprising vesicles having certain vesicle permeability

A process comprising the steps of:

• a) dispersing under mechanical shear a molten dialkyl quaternary ammonium compound selected from the group consisting of N,N-di(stearoyl-oxy-ethyl)-N,N-dimethyl ammonium chloride;
• N-stearyl-N-(stearoyl-oxy-ethyl)-N,N-dimethyl ammonium chloride;
• N,N-di(stearoyl-oxy-ethyl)-N-methyl,-N-(2-hydroxyethyl) ammonium methylsulfate;
• 1,2-distearoyloxy-3-N,N,N-trimethylammoniumpropane chloride;
• N N-di (hardenedtallowovl-oxv-ethyl)-N,N-dimethyl ammonium chloride;
• N-hardenedtallowvl -N-(hardenedtallowovl-oxv-ethyl)-N,N-dimethyl ammonium chloride;
• N,N-di(hardenedtallowovl-oxv-ethyl)-N-methyl-N-(2-hydroxyethyl) ammonium methyl sulfate;
• 1,2,-hardenedtallowoyloxy-3-N,N,N-trimethylammoniumpropane chloride;
• and mixtures thereof in hot water having a temperature above a transition temperature of said dialkyl quaternary ammonium compound;
• b) adding a perfume raw material to said dialkyl quaternary ammonium compound to form a mixture;
• c) dispersing said mixture into water having a temperature above a transition temperature of said dialkyl quaternary ammonium compound;
• and
• d) cooling said mixture to form a composition comprising vesicles having a vesicle permeability index of less than about 1.3 and perfume raw material;
• wherein the mixture formed by step (b) is formed either by;
• (i.) adding the perfume raw material to said hot water prior to the addition of the molten quaternary ammonium compound;
• or by
• (ii.) adding the perfume raw material to said hot water together with or after the addition of the molten quaternary ammonium compound.
