3. stearic acid is also widely used in the manufacture of PVC plastic pipes, plates, profiles and films. It is a heat stabilizer of PVC with good lubricity and good light and heat stability.

1.Application:    Stearic acid is widely used in cosmetics, plastics plasticizers, mold release agents, stabilizers, surfactants, rubber vulcanization accelerator, waterproof agent, polishing agent, metal soap, metal mineral flotation agents, softeners and pharmaceuticals as well as other organic chemicals. Stearic acid can also be used as the solvents of oil-soluble paint, crayons lubrication agent, stencil lighting agent and the emulsifier of stearic acid glyceride.
    
2.Application:    Stearic acid can also be widely used in the manufacturing of PVC pipe, sheet material, profiles and film and is the PVC heat stabilizers with good lubricity and excellent stability against light and heat. In the application of polyvinyl chloride pipe, stearic acid helps prevent the "coke" during the processing and is effective heat stabilizer during PVC film processing while also preventing the discoloration of the finished film discoloration caused by exposure.
    
3.Application:    Stearic acid has become the additive for lubrication, plasticization and stabilization of the filled masterbatch. Stearic acid can effectively improve the coating activating effect of inorganic powder and increase the flow rate of materials. When there is demand for a large flow rate of the melt for material with inorganic powder accounting for the most part, an appropriate increase in the content of stearic acid can significantly increase the melt flow rate of material.
    
4.Application:    The mono-or multi-alcohol ester of stearic acid can be used as cosmetics, nonionic surfactants and plasticizers. Its alkali metal salt can be dissolved in water and is a major component of soap. Other kinds of salts can be used as waterproofing agents, lubricants, bactericides, coating additives and PVC stabilizers.
    
5.Applications:    It can be used as natural rubber, synthetic rubber (except butyl rubber) and latex curing active agent. It can also be used as raw material of plastic plasticizer and stabilizer. Medicine: it can be used for the preparation of ointments, suppositories, etc., as well as being used in the manufacture of cosmetics, candles, waterproof agent and polishing agent. The product can be used as a lubricant, defoamers and food additives in the food industry as well as the raw materials of glycerol stearate, stearic acid sorbitol anhydride esters and sucrose esters.
    
6.Applications:    It can also be used as standard reference product for gas analysis as well as the preparation of soap, cosmetics, pharmaceuticals and other organic chemicals.
    
7.Applications:    Soaps , cosmetics , detergents
    
8.Applications:    Stearic acid is mainly used in the production of detergents, soaps, and cosmetics such as shampoos and shaving cream products. Soaps are not made directly from stearic acid, but indirectly by saponification of triglycerides consisting of stearic acid esters. Esters of stearic acid with ethylene glycol; glycol stearate and glycol distearate, are used to produce a pearly effect in shampoos, soaps, and other cosmetic products. They are added to the product in molten form and allowed to crystallize under controlled conditions. Detergents are obtained from amides and quaternary alkylammonium derivatives of stearic acid.
    
9.Applications:    Lubricants , softening and release agents
    
10.Applications:    In view of the soft texture of the sodium salt, which is the main component of soap, other salts are also useful for their lubricating properties. Lithium stearate is an important component of grease. The stearate salts of zinc, calcium, cadmium, and lead are used to soften PVC. Stearic acid is used along with castor oil for preparing softeners in textile sizing. They are heated and mixed with caustic potash or caustic soda. Related salts are also commonly used as release agents, e.g. in the production of automobile tires.
    
11.Applications:    Being inexpensively available and chemically benign, stearic acid finds many niche applications. When making plaster castings from a plaster piece mold or waste mold and when making the mold from a shellacked clay original. In this use, powdered stearic acid is mixed in water and the suspension is brushed onto the surface to be parted after casting. This reacts with the calcium in the plaster to form a thin layer of calcium stearate which functions as a release agent. When reacted with zinc it forms zinc stearate which is used a lubricant for playing cards (fanning powder) to ensure a smooth motion when fanning. In compressed confections, it is used as a lubricant to keep the tablet from sticking to the die.
    
12.Applications:    Fatty acids are classic components of candle - making. Stearic acid is used along with simple sugar or corn syrup as a hardener in candies.
    
13.Applications:    Stearic acid is used to produce dietary supplements.
    
14.Applications:    In fire works, stearic acid is often used to coat metal powders such as aluminium and iron. This prevents oxidation, allowing compositions to be stored for a longer period of time. Stearic acid is a common lubricant during injection molding and pressing of ceramic powders. It is also used as a mold release for foam latex that is baked in stone molds. .
    
15.Applications:    Stearic Acid is a fatty acid that is a mixture of solid organic acids obtained principally from stearic acid and palmitic acid. it is practi- cally insoluble in water. it functions as a lubricant, binder, and defoamer. it is used as a softener in chewing gum base.
    
16.Applications:    Pharmaceutic aid (emulsion adjunct); pharmaceutic aid (tablet and/or capsule lubricant).
    
17.Applications:    stearic acid is an emulsifier and thickening agent found in many vegetable fats. Stearic acid is the main ingredient used in making bar soaps and lubricants. It occurs naturally in butter acids, tallow, cascarilla bark, and in other animal fats and oils. Stearic acid may cause allergic reactions in people with sensitive skin and is considered somewhat comedogenic.
    
Definition:    A C18 straight-chain saturated fatty acid component of many animal and vegetable lipids. As well as in the diet, it is used in hardening soaps, softening plastics and in making cosmetics, candles and plastics.
    
General Description:    White solid with a mild odor. Floats on water.
