Eco-Friendly Triple Pressed 99% Purity Stearic Acid 1840 for Rubber/plastic

Triple pressed stearic acid is the highest grade product obtained through three rounds of hot pressing in the fatty acid freezing and separation process,It has an iodine value of 1-3,far lower than single pressed and double pressed grades,with a minimum purity of 98% for industrial specifications.Its melting point ranges from 67 - 69 degree, and it features extremely low impurity content, making it far more stable in high-temperature production scenarios than lower-grade stearic acid.

This 18 carbon saturated fatty acid has the molecular formula,appears as a white solid block or powder, acid value of 205-210,and moisture content controlled below 0.2%

Yes. Our triple-pressed stearic acid is manufactured in line with global raw material safety specifications, with heavy metal and harmful impurity limits far below the thresholds required for cosmetic-grade raw materials. It can be directly used to produce stearate derivatives for personal care products, and we support third-party testing to match regional market access rules.

It is widely applied in high-end cosmetic raw material production, fine organic chemical synthesis, as well as manufacturing of high-performance surfactants, rubber processing aids, metal soaps and plastic lubricants. It has been a core raw material in the global personal care industry for over a century, and most high-purity stearate ingredients for skincare products are produced from this grade.

Store the product in a cool, ventilated warehouse away from open flames and heat sources, and keep it separated from oxidizers, reducing agents and strong alkalis. It is slightly irritating to the respiratory tract, so standard dust-proof protective measures are required during operation to avoid prolonged direct contact with skin.
