Applications
1. Cosmetics and Personal Care
Isododecane丨CAS 31807-55-3 is widely used in cosmetics, particularly in oil-free formulations, due to its fast-drying and non-greasy feel. Common products include:
Long-wear foundations and concealers
Lipsticks and lip stains
Mascaras and eyeliners
Makeup removers
Hair styling products
2. Solvent and Carrier Agent
Acts as a non-polar solvent for active ingredients, pigments, and polymers.
Ideal for dissolving film formers, contributing to flexible and transfer-resistant makeup.
3. Formulation Enhancer
Improves spreadability, light texture, and skin feel.
Enhances product stability and water-resistance, especially in sunscreens and waterproof cosmetics.
4. Industrial Applications
Sometimes used in coatings, adhesives, and lubricants as a volatile hydrocarbon diluent.
Plays a role in aerosol formulations where quick evaporation is required without leaving residue.
Benefits
1. Fast-Drying and Lightweight
Rapid evaporation from skin or hair without leaving stickiness or heaviness.
Ideal for products that require a quick-set or long-lasting effect.
2. Non-Greasy Finish
Leaves a soft, silky feel, making it suitable for oil-free formulations or products aimed at oily or acne-prone skin.
3. Improves Wear and Transfer Resistance
Often included in long-wear and waterproof makeup due to its ability to lock in film formers and pigments.
4. Low Irritation Potential
Generally well-tolerated by skin, including sensitive skin types.
Not classified as a skin sensitizer or common allergen.
5. Volatile but Stable
Offers low viscosity and high volatility, enhancing the sensory profile without compromising formulation stability.
Summary
Isododecane丨CAS 31807-55-3 is a highly versatile branched hydrocarbon used extensively in the cosmetic and personal care industries. Its light, fast-drying nature and non-greasy finish make it essential for long-wear, waterproof, and oil-free formulations. It enhances performance and sensory appeal, making it a key ingredient in many modern beauty products.
