Abstract
Described is a process for forming controllably releasable fragrance-containing consumable articles, for example, encapsulated fragrances in detergents or fabric softener articles and compositions. The process includes the steps of: (a) forming an aqueous fragrance emulsion, including a modified starch; (b) spray drying or freeze drying the emulsion to form a fragrance-containing powder; and (c) mixing a solid consumable article base (e.g., detergent or fabric softener base) with the fragrance-containing powder. Also described are products produced by means of such processes as well as uses thereof.
Claims3
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;
- and
- 7-30% 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.
