About this product
Stearic acid (octadecanoic acid, CAS 57-11-4) is a saturated fatty acid supplied as white flakes or beads. The triple pressed grade we stock is a stearic/palmitic blend rather than pure C18. Buyers use it as a rubber compounding input, a soap and cosmetic base, a candle hardener, and a lubricant or release agent. We stock Godrej Hystric Triple Pressed Stearic Acid in 25 kg HDPE bags with LDPE liner at our Redhills, Chennai warehouse and dispatch across South India — TDS and MSDS are available to download.
