This invention relates to an improved crystallization process of hydrogenated castor oil structurant which results in (i) a dispersion having a high concentration of the structurant, and (ii) a crystal habit/form that results in a higher yield stress in the final product, imparting high stability, for a given amount structurant. In addition, the resulting personal care product is consumer desired, as less structurant residue is observed on hair after the use of the personal care product.
