About This Product
Commercial stearic acid derived from palm is a mixture rather than a single compound, and understanding that is essential to buying it correctly. It is produced by splitting palm oil or palm stearin into free fatty acids, then separating the saturated fraction, which is predominantly palmitic acid at sixteen carbons and stearic acid at eighteen. It is supplied as flakes, beads, powder or blocks.
Grades are identified by the ratio between those two acids, and conventionally by titre, the solidification temperature of the melted acid. A 40:60 grade holds roughly 40 percent palmitic to 60 percent stearic; 50:50 is the most widely traded; triple-pressed denotes a more thoroughly separated and lighter-coloured material. Because stearic acid melts about 8 degrees higher than palmitic, titre rises with the stearic fraction, and so does the hardness of the finished product. This is not a commercial nicety: a candle blend, a rubber compound and a cosmetic cream each need a different titre, and substituting one grade changes set point, hardness and appearance. Full saturation gives all grades good oxidative stability.
It is used in rubber vulcanisation as an activator, in PVC and polyolefin processing as a lubricant and stabiliser, in candles, in cosmetic creams and stick products, in soap, and in metal soap manufacture.
Bio Green Oleo supplies palm stearic acid grades to specification on titre, chain distribution, iodine value, acid and saponification value, colour and moisture.
