WHAT IS STEARIC ACID?
It’s a wax-like solid that is either white or colorless and has a bit of an unpleasant smell. 
You can dissolve it in oil, however, it is quite difficult to dissolve it in water, as it is waxy. 
It is only partially soluble in water, and so if it is mixed with water, you will find it floating 
on the water.

Stearic acid is used to harden and thicken 
products like bars of soap and candles. The 
presence of stearic acid in soap helps to create a 
lather when mixed with water, providing a velvety 
feeling.
It is this property that also makes it a must-have 
ingredient in most shaving foams and creams as 
well. 
When the soap formula is hardened into a solid, it 
helps to do away with the watered-down, runny 
feeling.

water can be mixed much better, and do not split 
into layers of oil and water.

Batteries
In the making of lead-acid batteries, stearic acid 
is used as a negative plate additive, as it helps to 
improve the plate’s hydrophobicity, especially 
when the battery has to be dry-charged. 
The stearic acid helps to reduce the oxidation 
extension of the negative active material, or the 
lead which forms afresh when the plates are left 
to dry in the open after the tank formation process 
is completed. 
This helps to reduce the time required for 
charging a dry battery for the first time 
considerably, when compared to a battery that 
does not feature added stearic acid in its plates.
