[Stearic acid supply and sales] The role and use guide of stearic acid in candles

Stearic acid is white flakes, beads or blocks at room temperature. solid. It is composed of saturated fatty acids mainly C16 and C18. It is insoluble in water, slightly soluble in benzene and carbon disulfide, easily soluble in hot ethanol, non-toxic and tasteless, and has the general chemical properties of organic carboxylic acids.

Stearic acid is a fatty acid widely found in nature. Almost all oils contain stearic acid in varying amounts. The content in animal fats is relatively high. For example, the content in butter can reach 24%. %, the content in vegetable oil is less, tea oil is 0.8%, palm oil is 6%, but the content in cocoa butter is as high as 34%. There are two main production methods for industrial stearic acid: fractionation method and pressing method. A decomposing agent is added to the hardened oil, and then it is hydrolyzed to obtain crude fatty acids, which are then washed, distilled, and decolorized to obtain the finished product, while glycerol is produced as a by-product.

The role of stearic acid in candles:

Stearic acid is extracted from vegetable oil, can burn, and can be used in candles. Material;

In addition, the price of mainstream paraffin is more expensive than stearic acid, so the main purpose of adding stearic acid is to reduce costs;

Adding stearic acid to candles can also increase the hardness. and whiteness, and burns without black smoke;

Stearic acid used in candles can also prevent candles from crying when burning:

The ideal raw material for rod wax is P401820 type Stearic acid; tea wax can use various types of stearic acid; the ideal raw material for cup wax is: P401005 type stearic acid.
