Controlled delivery system for fabric care products

This invention describes tiny, solid, spherical particles designed to deliver fragrance to fabrics. These particles, which are added to laundry products, stick to clothes and release scent over time or when ironed. Each particle contains a fragrance, a specific candelilla/silicon copolymer, and other ingredients that help it adhere to fabric.

Why it matters: Advances in microencapsulation and polymer chemistry since 2000 could simplify the synthesis and improve the performance of these specific particles.

Status: Not in forceListed as no longer active. The specific reason is not in the record we hold.
How hard to build: SpecializedMicroparticle formulation, specific chemical synthesis.
