Isoeicosane is a versatile, clear, odorless liquid hydrocarbon known for its low viscosity and excellent spreadability, making it ideal as a conditioning agent in hair care products such as rinses, conditioners, mousses, and sprays. Its non-greasy, highly stable, and non-comedogenic properties provide a silky texture and seamless integration with other ingredients, ensuring dermatological safety. Additionally, isoeicosane serves as an effective lipophilic carrier in skin and sun care products and functions as a plasticizer for resins in hair styling gels and mousses.
