Technical Data of Zinc dodecyl stearate:

How is Zinc Dodecyl Stearate produced?
Preparation technology of zinc stearate comprises the following steps that 1, glyceryl tristearate and water are under the action of a catalyst and an antioxidant; 2, zinc oxide and a catalyst are added stepwise, condensing, dewatering and salt-forming are conducted, and zinc stearate is synthesized.

Application of Zinc Dodecyl Stearate:
Zinc Dodecyl Stearate is widely used in lubricant, stabilizer, decolorizing agent and thickener. Used in the process of release molding of polystyrene resin, phenolic resin, amino resin. It is an excellent rubber and plastic auxiliaries, also are the surfactant and softener.

Zinc dodecyl stearate is a common surfactant and polymer modifier with various industrial applications. This article will provide a detailed introduction to the definition, application scenarios, chemical and physical properties, production methods, and future development directions of zinc dodecyl stearate.

In daily chemicals, textiles, plastics, coatings, etc., zinc dodecyl stearate is widely used in detergents, wetting agents, emulsifiers, and dispersants. As an efficient surfactant, it can reduce the surface tension of liquids and improve their wettability. In addition, zinc dodecyl stearate can also be used as a polymer modifier to improve the processing performance, heat resistance, weather resistance, and mechanical strength of materials.

Regarding chemical properties, zinc dodecyl stearate has high acid and saponification values. The acid value indicates the content of free acids in it. In contrast, the saponification value represents the amount of potassium salt generated by the saponification reaction with potassium hydroxide. These indicators directly affect zinc dodecyl stearate's chemical reactivity and product quality.

Regarding physical properties, zinc dodecyl stearate has good melting point and solubility characteristics. The melting point can reflect its purity and crystallinity, while solubility is closely related to its solubility and application performance in solvents. In addition, its expansion coefficient is small, making it suitable for special polymer modification situations that require controlled expansion.

Regarding production methods, zinc dodecyl stearate is mainly prepared by saponification reaction between stearic acid and zinc salt. Saponification reactions generally use sodium hydroxide or potassium hydroxide as catalysts. Factors such as saponification reaction temperature, reaction time, and catalyst dosage will impact production efficiency and product quality. The product obtained through the saponification reaction is then neutralized to obtain zinc dodecyl stearate with an ideal acid-base value. Finally, excess stearic acid is removed through thermal decomposition to obtain high-purity zinc dodecyl stearate.

FAQs of Zinc Dodecyl Stearate

Q: What is zinc dodecyl stearate used for?

A: Zinc dodecyl stearate serves a variety of functions across different industries due to its unique properties. In cosmetics and personal care products, it acts as an opacifying agent, emulsion stabilizer, and thickening agent, contributing to the texture and stability of formulations like creams, lotions, and foundations. It also finds use in the manufacturing of lubricants and greases, where it provides excellent wear resistance and anti-corrosion properties. Additionally, zinc dodecyl stearate can be utilized in the production of plastic additives, enhancing their thermal stability and processing characteristics. The compound is also valuable in the pharmaceutical industry for its ability to improve the flowability and compressibility of powders during tablet manufacturing.
 

Q: Is zinc dodecyl stearate safe for humans?

A: Zinc dodecyl stearate is generally recognized as safe (GRAS) for use in cosmetic and personal care products when used within recommended concentration limits and following good manufacturing practices. Studies indicate that this compound has low toxicity and does not cause significant irritation or sensitization when applied topically. However, precautions should still be taken during handling to avoid inhalation of dust particles and contact with eyes. Personal protective equipment such as gloves, safety glasses, and respiratory protection can help ensure safe usage. For specific applications, especially those involving ingestion or prolonged skin contact, it's advisable to consult relevant safety data sheets and regulatory guidelines.
 

Q: What is the chemical composition of zinc dodecyl stearate?

A: Zinc dodecyl stearate is a metal soap formed by the reaction between zinc oxide and dodecyl stearate. Its chemical structure includes zinc ions (Zn²⁺) and organic fatty acid chains derived from stearic acid with a dodecyl (12-carbon) group attached. This combination results in a material that possesses both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties, making it versatile for various applications. The precise ratio of components may vary depending on the manufacturing process and intended use, allowing for customization of physical and chemical properties to meet specific requirements.
 

Q: How does zinc dodecyl stearate perform in skincare products?

A: Zinc dodecyl stearate performs admirably in skincare products, offering several benefits. As an opacifying agent, it helps create a more opaque appearance in formulations, which can enhance the coverage and hiding power of makeup products. Its emulsifying capabilities contribute to the stability of water-in-oil or oil-in-water emulsions, ensuring that the product remains uniform over time without separating. Moreover, zinc dodecyl stearate can impart a smooth, silky feel to the skin, improving the overall sensory experience of using the product. It also assists in controlling shine by absorbing excess sebum, making it suitable for use in matte-finish cosmetics. Importantly, zinc dodecyl stearate is non-toxic, non-irritating, and non-sensitizing, which aligns well with the safety standards expected in skincare formulations.
