Description of 12-hydroxystearic acid
Dodecyl stearic acid, also known as 12-hydroxystearic acid, is insoluble in water but soluble in ethanol, ether, and chloroform.
12-hydroxystearic acid is prepared by hydrogenation of cis-ricinic acid.
12-hydroxystearic acid is a white, flaky, or acicular crystalline solid at room temperature and pressure, with remarkable acidity, insoluble in water, and soluble in ethanol, ether, and chloroform.

Uses of 12-hydroxystearic acid
1.12-hydroxystearic acid mainly produces high-temperature resistant, high-quality lithium base grease. It can also make textile lubricants, insulation mixtures, shoe polish, polish, cosmetics, pharmaceuticals, coatings, metal processing oil, etc. It has good lubrication performance, can reduce the friction and wear of the metal surface, and can extend the service life of mechanical equipment. 12-hydroxystearic acid can reduce the viscosity and viscosity of the lubricant and improve the lubrication effect; it is widely used in the manufacture of lubricating oil, cutting fluid, coolant, and other industrial lubricants.
2.12-hydroxystearic acid has good thickening, emulsification, stability, and lubrication properties, which can enhance the texture and elasticity of cosmetics. It is often used as an important ingredient in skin care products. It also has moisturizing and antioxidant functions.
3.12-hydroxystearic acid is used in the coatings and ink industry. Excellent thickening and emulsifying properties improve the viscosity and stability of coatings and inks. It can also enhance the adhesion and durability of the coating and improve its gloss and waterproof performance.
4.12-hydroxystearic acid can be blended with plastics to enhance their toughness and heat resistance. Improve plastics' melting fluidity and molding properties, making plastic products easier to process and form, such as processing plastic film and plastic packaging materials.
5.12-hydroxystearic acid can be used in electronics and electrical synthesis of polymer materials as an encapsulation material for electronic components, providing protection and insulation functions.

FAQs of 12-hydroxystearic acid:
Q: How does dodecyl stearate affect texture and stability in cosmetic formulations?
A: In cosmetic formulations, dodecyl stearate can significantly enhance the texture and stability of products: Texture Improvement: It imparts a silky feel and softness to products, allowing for smoother application while leaving a long-lasting moisturizing effect without greasiness. Stability Enhancement: As an effective emulsifier, Dodecyl Stearate helps to form stable oil-in-water (O/W) emulsion systems, preventing oil-water delamination and extending product shelf life. Structural reinforcement: when acting synergistically with other ingredients, it can build a three-dimensional network structure, increase the overall consistency, and avoid the problem of precipitation or caking.
Q: What safety precautions should be taken when using Dodecyl Stearate?
A: Although dodecyl stearate is considered a relatively safe chemical, the following points should be noted during handling and use: Skin contact: Prolonged direct contact may cause slight irritation, gloves are recommended for handling, if inadvertently contaminated with skin, wash immediately with soap and water. Eye Protection: Avoid getting the powder into your eyes, if it gets into your eyes inadvertently, flush immediately with plenty of water for at least 15 minutes and seek medical help. Inhalation Risk: Avoid inhaling the dust as much as possible, especially when handling the substance in a dry environment, make sure that the working area is well ventilated. Storage conditions: Store in a cool, dry place away from sources of ignition and strong oxidizing agents to prevent accidents. Waste Disposal: Dispose of waste dodecyl stearate and its packaging containers properly in accordance with local regulations and do not dump into the environment.
Q: What is the impact of dodecyl stearate on the environment? Is there any ecological risk?
A: Regarding the specific environmental impacts of dodecyl stearate, current studies show that it is biodegradable and therefore relatively easy to be decomposed by microorganisms in the natural environment. However, it may still cause some stress to aquatic ecosystems in case of high concentration discharge: Biodegradability: As a fatty acid, dodecyl stearate has good biodegradability and can be metabolized to carbon dioxide and water by microorganisms in nature in a relatively short period of time. Ecotoxicity: Although it is relatively harmless to higher plants and animals, excessive concentrations may have certain toxic effects on aquatic organisms, especially phytoplankton, affecting their growth and reproduction. Wastewater Treatment: During industrial wastewater treatment, effective measures should be taken to minimize the discharge of wastewater containing dodecyl stearate, such as physicochemical removal of excess organic matter or biological treatment techniques to convert it to a more stable form. In order to minimize potential environmental risks, it is important to use and manage dodecyl stearate appropriately, and to pay attention to the trend of environmental protection policies and technologies.
Q: How do I select the right supplier and product quality of dodecyl stearate for a particular application?
A: Selecting a supplier of dodecyl stearate that best suits the needs of the project and ensuring product quality are critical steps in ensuring the performance of the final product: Define the need: Start by identifying the requirements of the specific application, such as the desired purity grade, particle size, melting point range, and other characteristics, as well as the need to meet specific standards or certifications (e.g., FDA, REACH, etc.). Supplier reputation: Examine the supplier's track record, customer reviews and service levels, prioritizing those with extensive experience and a good reputation. Sample testing: Request samples from potential suppliers and conduct comprehensive testing in laboratory or small-scale pilot production conditions to assess whether their actual performance meets expectations. Price and supply stability: Consider the market price of the product, the volume discount policy and the reliability of long-term supply to find the most cost-effective partner. Technical support: Choose a supplier that can provide detailed technical support and solutions, so that you can get timely and effective help when you encounter technical problems. Environmental compliance: Ensure that the selected products comply with local environmental standards and have the appropriate certification documents to cope with the increasingly stringent environmental protection regulations.
