Battelle Encapsulation Technology Platform

Disperse/Solubilize monomer(s) in suitable medium Polymerization Smart Capsules Emulsion, Suspension or Dispersion Polymerization

Capsules are designed based on application: active ingredient and trigger mechanism

Battelle Smart Laundry Capsule ™

• Encapsulation of bleach activator for more effective bleach product in cold water washing • Release of activator triggered in-wash by pH change • Capsule “shell” is biodegradable polymer Encapsulated Bleach Activator

The consumer benefits from the Smart Laundry Capsule

Better Cleaning Energy Savings Biodegradable

Battelle process achieves complete encapsulation of active ingredient
