Description

1-(Hydroxymethyl)Pentadecyl Palmitate is a specialized ester compound with the CAS registry number 62604-71-1. This chemical is valued for its unique structural properties, which combine a long-chain fatty acid with a hydroxymethyl functional group, offering versatility as an intermediate or functional additive. It is primarily sought after by manufacturers in the personal care, cosmetics, and specialty chemical industries for formulating emollients, viscosity modifiers, and base materials for further synthesis.

Application

• As a key emollient and skin-conditioning agent in high-end cosmetic and personal care formulations such as creams, lotions, and ointments.
• Utilized as a viscosity modifier and texture enhancer in cosmetic products to improve spreadability and sensory feel.
• Acts as a specialized intermediate in the synthesis of more complex esters, polymers, and surfactants for industrial applications.
• Potential use as a lubricant base stock or additive in specialty lubricants and release agents.
• Employed in pharmaceutical excipient development for topical drug delivery systems.
• Serves as a raw material in the production of waxes and coatings requiring specific melting points and hydrophobic properties.

Quality Control

Our 1-(Hydroxymethyl)Pentadecyl Palmitate is produced under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure it meets precise specifications for identity, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, acid value, and hydroxyl value are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in opened containers to maintain stability and prevent degradation. Keep away from strong oxidizing agents.
