Biobased polyester-based oil gelator for cosmetic applications

Overview

The biobased polyester-based oil gelator developed by Loop CO2, Inc. offers an innovative solution for the cosmetics industry. By utilizing a CO₂-derived, noncrystalline polyester, this technology creates stable, reversible gels that function efficiently at low concentrations (<10 wt%). The process capitalizes on crystallization-driven structuring, forming a three-dimensional network that immobilizes the oil phase without the need for chemical crosslinking or curing. With a Natural Origin Index (NOI) >80%, it aligns with sustainability goals and is compatible with standard personal care manufacturing processes.

Technical specifications

Key features:

• Utilizes CO₂-derived noncrystalline polyester and PLA-derived crystalline segments
• Forms stable, reversible gels upon cooling from processing temperatures ≤90 °C
• Functions efficiently at low use levels (<10 wt%)
• Colorless and low-odor, enhancing sensory properties
• Compatible with natural positioning, achieving a high NOI based on ISO 16128-2

Applications:

• Suitable for creating gels, balms, and sticks in personal care products
• Compatible with representative anhydrous cosmetic oils

Technology readiness level

The technology is currently at TRL 3, indicating experimental proof of concept. Material-level validation is ongoing, focusing on blending the CO₂-derived polyester oil with PLA-derived crystalline components. Future development may include chemical copolymerization for enhanced performance, pursued through collaborative arrangements.
