Description

2-[(Hexadecanoyloxy)Methyl]-2-Methyl-1,3-Propanediol Dihexadecanoate is a high-purity, fully saturated diester compound derived from palmitic acid. This specialty chemical is valued for its excellent emollient properties, stability, and ability to modify the texture and melting profile of formulations. It serves as a key functional ingredient for manufacturers in the personal care, cosmetics, and specialty lubricants industries seeking consistent performance and superior skin feel.

Application

• Cosmetic & Personal Care Emollient: Used in creams, lotions, lipsticks, and sunscreens to provide a non-greasy, velvety skin feel and enhance spreadability.
• Structuring & Thickening Agent: Imparts structure and increases the viscosity of stick formulations such as deodorants, solid perfumes, and makeup sticks.
• Skin Protectant & Moisturizer: Acts as an occlusive agent in skincare products to help reduce transepidermal water loss (TEWL) and improve skin hydration.
• Specialty Lubricants & Release Agents: Employed in niche industrial applications requiring stable, non-reactive lubricants with specific melting characteristics.
• Pharmaceutical Ointment Base: Serves as a component in topical pharmaceutical preparations where a stable, inert, and smooth base is required.
• Raw Material for Synthesis: Used as an intermediate or starting material for the synthesis of more complex esters and polymer additives.
