Calcium stearate, an internal lubricant which reduces friction between PVC grains during processing, is commonly used in plasticized PVC, which is melt-processed. External lubricants, essential in rigid PVC compounds, are not always necessary when plasticizers are present. Intracellular accumulation of stearic Acid in MPMs activates inflammatory signalling, leading to ER stress–mediated apoptosis. M1 macrophages are more prone to stearic Acid–induced inflammation and ER stress. Stearic Acid causes hypercoagulability of the blood by activating factor XII and by aggregating blood platelets. Injection of unbound stearic Acid (sodium salt) into the systemic circulation of dogs was followed by massive generalized thrombosis and sudden death. Sodium stearate is generally recognized as non-toxic.
Ingesting large amounts could cause digestive upset, or inhaling it in powder form could cause respiratory irritation. However, as used in most products, it's generally non-toxic. It's not a known reproductive toxin (endocrine disruptor) and not a known carcinogen. It is essentially a synthetic ingredient that is a product obtained as a reaction between Stearic Acid and Calcium Oxide when heated together. Calcium Stearate is generally non-toxic. It is considered to be the most important type of Calcium Salt. Stearic Acid is most soluble in ethyl acetate and least soluble in methanol. The solubility of stearic Acid in four solvents in order of increasing solubility is methanol, acetone, ethanol and ethyl acetate. Other names for Palm oil include Palmate, Cetyl Palmitate and Octyl Palmitate, plus more, such as Sodium Lauryl Sulfate, which can be made from Palm Oil. With these different names, you may be supporting the palm oil industry without even knowing! Be sure to check your labels.
