甘油即丙三醇，为无色味甜澄明黏稠液体。无臭，有暖甜味。能从空气中吸收潮气，也能吸收硫化氢、氰化氢和二氧化硫。对石蕊呈中性。长期放在0℃的低温处，能形成熔点为17.8℃有光泽的斜方晶体。

Glycerol, also known as glycerol, is a colorless, sweet, clear, and viscous liquid. Odorless, with a warm and sweet taste. It can absorb moisture from the air, as well as hydrogen sulfide, hydrogen cyanide, and sulfur dioxide. Neutral to litmus. Long term exposure to a low temperature of 0 ℃ can form shiny rhombic crystals with a melting point of 17.8 ℃.

丙三醇是甘油三酯分子的骨架成分。当人体摄入食用脂肪时，其中的甘油三酯经过体内代谢分解，形成甘油并储存在脂肪细胞中。因此，甘油三酯代谢终产物便是甘油和脂肪酸。那么甘油在化学工业及轻工业有哪些应用呢？下面氢氧化钾厂家为您分析：

Glycerol is the backbone component of triglyceride molecules. When the human body ingests edible fat, the triglycerides in it undergo metabolic decomposition in the body to form glycerol and store it in fat cells. Therefore, the end products of triglyceride metabolism are glycerol and fatty acids. So what are the applications of glycerol in the chemical and light industries? The following potassium hydroxide manufacturer will analyze for you:

1、甘油可应用于树脂工业制造酯树胶，酯树胶又称为甘油三松香酸酯或松脂胶。可以用甘油与8.5~10.5份的松香在230~290℃之间酯化而成，可获得比原来的松香更硬、更接近于中性而且更能抗水的酯胶，在工业上有很广泛的用途。

1. Glycerin can be used in the resin industry to manufacture ester gum, which is also called glycerol trisrosin ester or rosin gum. It can be esterified with glycerol and 8.5~10.5 parts of rosin between 230~290 ℃ to obtain ester gum that is harder, closer to neutral, and more water resistant than the original rosin. It has a wide range of industrial applications.

2、在涂料工业中用以制取各种醇酸树脂、聚酯树脂、缩水甘油醚和环氧树脂等。以甘油作为原料制成的醇酸树脂是良好的涂料，可以代替快干漆和磁漆，并且绝缘性能良好，可应用于电器材料。

2. Used in the paint industry to produce various alkyd resins, polyester resins, glycidyl ethers, and epoxy resins. Alkyd resin made from glycerol as a raw material is a good coating that can replace quick drying paint and enamel, and has good insulation performance, which can be applied to electrical materials.

3、甘油在化妆品产品中可作保湿剂、降粘剂、变性剂等使用，所以广泛应用于化妆品中（如面霜、面膜、洗面奶等）。使用甘油成分的护肤品能够使皮肤保持柔软，富有弹性，不受尘埃、气候等损害而干燥，起到保湿、润肤的作用。

3. Glycerin can be used as humectant, viscosity reducer, denaturant, etc. in cosmetics, so it is widely used in cosmetics (such as face cream, facial mask, facial cleanser, etc.). Skincare products using glycerol ingredients can keep the skin soft, elastic, and dry from dust, climate, and other damage, playing a moisturizing and moisturizing role.

4、甘油大量应用在玻璃纸的生产上作业增塑剂，赋予玻璃纸必要的柔软性并防止玻璃纸破碎。在造纸工业上运用于皱纸、薄纸、防水纸及蜡纸等。

4. Glycerin is widely used in the production of cellophane as a plasticizer to give cellophane the necessary softness and prevent cellophane from breaking. Used in the paper industry for wrinkled paper, thin paper, waterproof paper, and waxed paper.

5、在纺织工业中，甘油被用作纺线编织时的润滑剂，因为它能完全溶解在水中，并且极容易在纤维上洗去，甘油应用在印染工业中，对染色的渗透和均匀度均有帮助，一般用量为5%。复合甘油的衍生物可作为洗涤剂、渗透剂及乳化剂应用。

5. In the textile industry, glycerol is used as a lubricant for spinning and weaving because it can completely dissolve in water and is easily washed off on fibers. When glycerol is used in the printing and dyeing industry, it helps to improve the penetration and uniformity of dyeing, with a general dosage of 5%. Derivatives of composite glycerol can be used as detergents, penetrating agents, and emulsifiers.

6、甘油在照相技术中主要作为胶片的增塑剂，可防止胶片龟裂和收缩。

6. Glycerin is mainly used as a plasticizer in photography to prevent film cracking and shrinkage.

7、橡胶制品浸在甘油中贮存，比暴露在空气中贮存，在时间上可以延长得很多。甘油在橡胶工业上作硫化介质和润滑剂用。

7. Rubber products stored in glycerol can be stored for a much longer time than when exposed to air. Glycerin is used as a vulcanizing medium and lubricant in the rubber industry.
