Product Name: Stearic Acid

HS Code: 3823110000

Packaging: 25kg Kraft paper/plastic bag or Customized package;

Stearic Acid is a saturated long-chain fatty acid naturally present in various animal and vegetable oils and fats. It is primarily produced through the hydrolysis of oils and fats. The powder form is one of the important commercial specifications of stearic acid. In fields such as pharmaceuticals and food, where uniform mixing is highly required, powdered stearic acid can disperse more evenly with other components in the formulation compared to flake or bead products, thereby delivering more stable functional performance.

Primary Applications in the Food Sector

Coating Agent: The function of a coating agent is to form a protective film on the food surface, providing effects such as moisture resistance, oxidation resistance, and appearance preservation.

Release Agent: During the candy forming process, stearic acid prevents the candy from sticking to the molds, ensuring smooth demolding. It can also be used as a release agent and surface treatment agent for chocolate products.

Emulsifier & Stabilizer: Stearic acid and its derivatives (such as mono- and diglycerides of fatty acids) play an emulsifying role in food.

Primary Applications in the Cosmetics & Personal Care Sector

Emulsifier & Emulsion Stabilizer: Stearic acid is a foundational ingredient in skin care products such as creams and lotions.

Cleansing Agent & Surfactant: In facial cleansers and soaps, stearic acid plays an important cleansing role, helping to produce a rich, creamy lather that gently removes dirt and excess oil from the skin's surface.

Thickener & Texture Modifier: It increases product viscosity, improves the sensory feel, and regulates the rheology of systems in shampoos and conditioners.

Hardener: It provides a hardening effect in soaps, candles, and crayons, helping products maintain their solid shape and improving structural stability.

Primary Applications in the Pharmaceutical Sector

Powdered stearic acid is widely used in the pharmaceutical industry, primarily as a pharmaceutical excipient.

Tablet & Capsule Lubricant: This is the most core application of stearic acid in pharmaceuticals. Added as a lubricant to tablet and capsule formulations, it reduces friction between the powder and the die wall during compression, ensuring smooth ejection of the tablets.

Binder & Coating Aid: It can be used in combination with shellac as a binder for tablet coatings.

Sustained-Release Carrier: It can act as a sustained-release carrier for drugs, controlling the release rate of the active ingredient in the body.

Topical Formulation Component: It is used as an emulsifier and solubilizer in topical preparations.

Primary Applications in the Industrial Sector

Plastics & Rubber Industry: Stearic acid is an important heat stabilizer, lubricant, release agent, plasticizer, and softener in plastic and rubber processing.

Candle Manufacturing: Stearic acid is an important raw material in candle production. It increases the hardness and melting point of candles, making them burn longer and maintain a more stable shape, while also improving the surface gloss of the candles.

Coatings & Inks: It is used as a lubricant and dispersant in printing inks, and to improve flowability and surface properties in coatings.
