Abstract:
A process for forming a solid phase particulate controllably releasable fragrance-containing detergent-fabric softening composition consisting of the sequential steps of:(i) initially admixing by means of homogenization water, a maltodextrin, a hydrophobic modified starch and at least one hydrophilic fragrance ingredient in order to form an aqueous fragrance emulsion containing:40-60% by weight water;3-30% by weight maltodextrin;10-40% by weight hydrophobic modified starch; and7-30% by weight hydrophilic fragrance;(ii) spray drying or freeze drying the resulting aqueous fragrance emulsion whereby solid phase fragrance-occluded carbohydrate particles are formed having a particle size of from about 3 up to about 10 microns and a fragrance content of from 15-50% by weight are formed;(iii) admixing a solid powdered detergent with a solid phase clay softener to form a solid phase powdered detergent-softener composition; and(iv) blending the solid phase fragrance-occluded carbohydrate particles with the powdered detergent-softener composition, thereby forming the solid phase particulate controllably releasable fragrance-containing detergent-fabric softening composition.
