Controlled Release Membrane Delivery System for Ambient Treatment Applications

Abstract/Technology Overview

This technology encapsulates a high level of volatile actives and then continuously releases them in controlled dosages. The gel matrix is enclosed by a protective foil which is further packaged in a vapor-permeable membrane, to create the ready-to-use and easy to apply the product. Upon activation, the volatile actives are delivered for a nonstop ambient treatment effect. Using this advanced but simple system, actives such as fragrances, essential oils, odour-neutralizing agents, and even insecticides can be dispersed into ambient spaces.

Technology Features, Specifications and Advantages

  • Processing at ambient temperatures (20 - 30˚C)
  • Processing at low pressures (5 - 50 psi)
  • Incorporates actives in liquid states, with payloads of up to 90%
  • Diffuses actives without machinery or power sources
  • Activated by airflow from air-conditioning systems
  • Compatible with all types of air-conditioning systems
  • In solid form, with no potential for leaks or spills
  • Invisible after application

Potential Applications

  • Air purification - e.g. controlled dosing of Tea Tree Oil to combat airborne bacteria and mold
  • Air freshening - e.g. controlled dosing of fragrances to freshen the environment
  • Odor remediation - e.g. controlled dosing of odor counteractants to combat odors
  • Scent marketing - e.g. controlled dosing of food scents for drawing crowds
  • Pest control - e.g. controlled dosing of pest repellants to repel pests

Customer Benefit

  • Prolonged and continuous ambient treatment effect
  • Reduce dosage frequency
  • No direct contact with volatile actives
  • Safe and easy to use
  • Easily transported by air or sea as non-DG goods
  • Environmentally friendly
