硬脂酸：在化妆品工业中，是制造一般乳化制品不可缺少的原料，用于配制雪花膏、冷霜、粉底霜、剃须膏、发乳及护肤乳液等。在橡胶工业中，是天然前、合成胶及胶乳的硫化活性剂，还用作软化剂。塑料工业中用作增塑剂、稳定剂及润滑剂。纺织工业中用作纱线润滑剂及制造丝光膏柔软剂。还用于制造脱模剂、抛光膏、消泡剂、金属浮选剂，油漆平光剂、蜡纸打光剂、纺织品防水剂等产品，是油溶性颜料的溶剂，也是制造硬脂酸锌、硬脂酸钙、硬脂酸铅等硬脂酸酯及硬脂酸盐的原料。
Stearic acid: in the cosmetic industry, it is an indispensable ingredient in the manufacture of general emulsified products. It is used in the preparation of snow cream, cold cream, foundation cream, shaving cream, hair cream and skin care lotion. In rubber industry, it is a vulcanizing activator for natural, synthetic rubber and latex, and also used as softener. Plastics industry is used as plasticizer, stabilizer and lubricant. Textile industry is used as yarn lubricant and softening agent for making mercerizing paste. It is also used for the manufacture of demoulding agent, polishing paste, defoaming agent, metal flotation agent, paints, wax paper, and textile waterproofing agents. It is the solvent of oil soluble pigment, and also the raw material for making stearate, calcium stearate, lead stearate and stearate and stearate.
硬脂酸盐：可以作为PVC的热稳定剂，增加透明和半透明度、软化剂、润滑剂、成膜剂。能与PVC受热分解出来的盐酸作用防止分解；同时还是很好的光稳定剂，能够抑制紫外线对薄膜的老化，延长其寿命。
Stearate: it can be used as a heat stabilizer for PVC to increase transparency and transparency, softeners, lubricants and film-forming agents. It can prevent decomposition from the hydrochloric acid decomposed by PVC; at the same time, it is also a good light stabilizer that can inhibit the aging of the ultraviolet light on the film and prolong its life.
在油漆工业中做催干剂，缩短干燥时间，同时还可以做平光剂。在高分子材料中用作脱模剂、活化剂、稳定剂、润滑剂、软化剂等，在机械工业中，可以做高温固体润滑剂。橡胶制品的耐高温粉模剂。润滑油和胶黏剂的增厚剂，润滑脂耐温剂以及纸张、涂料、防水、防雨材料的防水剂。铅笔芯润滑剂，医药中药品的粉模剂。化妆品行业的增稠剂、润滑剂，还可以用作织物及建筑材料的防水剂等。
In the paint industry, the drying agent is used to shorten the drying time, and at the same time, it can also be used as a flatting agent. As a release agent, activator, stabilizer, lubricant, softener and so on, it can be used as a high temperature solid lubricant in the mechanical industry. High temperature resistant powder mold agent for rubber products. Thickening agents for lubricating oils and adhesives, grease heat-resistant agents and waterproofing agents for paper, coatings, waterproofing and rain proofing materials. Pencil core lubricants, pharmaceutical powder formulations. The thickeners and lubricants in the cosmetics industry can also be used as waterproofing agents for fabrics and building materials.
