Description

2-Ethyl-2-(Hydroxymethyl)Propane-1,3-Diyl Dinonan-1-Oate is a specialized diester compound, specifically the diisononanoate ester of trimethylolpropane. This matters for formulators seeking a high-performance, non-greasy emollient and solvent with excellent oxidative stability and low volatility. It is primarily needed by manufacturers in the personal care, cosmetics, and specialty lubricants industries for creating premium products with superior skin feel and lasting performance.

Application

• Personal Care & Cosmetics: Acts as a high-spreadability, non-occlusive emollient in sunscreens, creams, lotions, and color cosmetics, providing a dry, silky skin feel.
• Hair Care Formulations: Used in conditioners, hair oils, and styling products to impart gloss, reduce tackiness, and improve combability.
• Plasticizer & Lubricant: Serves as a specialty plasticizer for polymers and a synthetic base oil or lubricant additive in high-performance industrial applications.
• Carrier & Solvent: Functions as an effective carrier for active ingredients and a solvent for UV filters and fragrances in cosmetic and industrial formulations.
• Skin Care Products: Ideal for anti-aging serums, moisturizers, and body butters due to its excellent skin compatibility and ability to enhance product texture.
• Industrial Coatings & Inks: Employed as a low-volatility coalescing agent or modifier to improve flexibility and application properties.
