ISONONYL ISONONANOATE is a synthetic branched-chain ester widely used in cosmetics and personal care formulations. Here are its key chemical characteristics:
1. Chemical Structure:
Alcohol moiety: Isononanol (branched C₉H₁₉OH, e.g., 3,5,5-trimethylhexanol).
Acid moiety: Isononanoic acid (branched C₈H₁₇COOH, e.g., 7-methyloctanoic acid).
Ester linkage: Formed by condensation of the two.
Formula: Typically C₁₈H₃₆O₂ (varies slightly by isomer).
2. Key Properties:
Texture: Lightweight, non-greasy silicone-alternative emollient.
Spreadability: Excellent due to low viscosity and high branching.
Stability: Resistant to oxidation (branched chains lack reactive sites).
Compatibility: Mixes well with oils, UV filters, and pigments.
3. Primary Applications:
Skincare: Serums, sunscreens, moisturizers (enhances sensory feel).
Makeup: Foundations, primers (improves blendability, reduces tackiness).
Haircare: Conditioners (adds slip without buildup).
INCI Name: Isononyl Isononanoate (global regulatory acceptance).
4. Functional Advantages:
Replaces cyclomethicone in "silicone-free" claims.
Reduces whitening in SPF formulations.
Enhances water resistance.
Note: Its performance stems from branching in both chains, which prevents crystallization and delivers a smooth, dry finish.
