Tunable HIPE chassis for sustained fragrance release
Introducing a tunable high internal phase emulsion (HIPE) technology designed for efficient and prolonged volatile scent release. This innovative chassis allows for high fragrance oil loading and controlled evaporation, enhancing scent persistence across various topical formats.
Overview
The tunable HIPE chassis offers a breakthrough in fragrance delivery by providing a stable and efficient carrier for volatile scent compounds. This technology utilizes structured water-in-oil (W/O), oil-in-water (O/W), or gel-in-gel HIPEs with high internal phase loading, ensuring extended fragrance release. By managing the oil-to-water ratio, natural stabilizers, droplet size, and rheology, the chassis minimizes phase separation and reduces fragrance entrapment. This innovation is ideal for applications in ointments, sticks, roll-ons, creams, and sprays, ensuring a strong initial scent and prolonged release.
Technical specifications
- High internal phase emulsion (HIPE) technology: Utilizes structured emulsions for fragrance delivery
- Pickering stabilization: Ensures stability with whey protein microgels and renewable polysaccharide networks
- Customizable formulation: Tunable oil/water ratios and interfacial cross-link density for specific release profiles
- Extended fragrance release: Controls interfacial resistance and diffusion pathways to minimize burst evaporation
- Versatile application formats: Suitable for ointments, creams, roll-ons, and sprays
Technology readiness level
This technology is at TRL 4, indicating that it has been validated at a laboratory scale. Future steps involve aligning with target topical formats, developing a formulation matrix, and conducting stability tests under accelerated conditions. Further validation will include scale-up recommendations and regulatory considerations for over-the-counter (OTC) topical applications.
