Melissic acid

CAS: 506-50-3

Overview

Melissic acid (CAS 506-50-3 ), also known as triacontanoic acid and myricic acid, is a long-chain saturated fatty acid naturally occurring in beeswax and plant waxes.

It functions as a structuring agent, emulsifier, and lubricant component across industrial and specialty formulation markets. In personal care and cosmetics, it contributes to the solid structure of wax-based formulations.

Common applications include lip balms, stick deodorants, and emollient creams. Industrial lubricant manufacturers incorporate it into high-temperature grease and metalworking compounds where long-chain fatty acid components improve film durability.

The material enhances surface adhesion in heavy-duty industrial settings. Food-grade applications include use as a processing aid and surface coating component in confectionery and baked goods, where it supports release and texture.

Specialty wax blends for packaging and coating also utilize it as a hardening and dispersing component. This versatile fatty acid is supplied as a white to off-white powder or flake solid for easy handling.

Technical grade is the most commonly available specification, with purity levels typically ranging from 85% to 98%+ depending on the source and intended application. High purity ensures consistent performance.

Food-grade and cosmetic-grade material meeting FCC or comparable standards is available from select suppliers for regulated end uses. This ensures compliance with strict safety and quality requirements.
