What is Zinc Stearate Used For?
Recently, covid 19 outbreak spreads in Shanghai, China. There are more than 25,000 new asymptomatic domestic infections every day. China is implementing a dynamic zero-out policy. A leading respiratory expert said the key to COVID-19 prevention and control is to minimize transmission and fatality rate. Omicron has a low case fatality rate but is highly transmissible and can still claim many lives in large outbreaks. "Total openness is not applicable in China. For China, we should keep to the dynamic zero-out and gradually open up."
However, "dynamic zero clearance" is not the pursuit of complete "zero infection". As the Novel Coronavirus has its own uniqueness and strong concealment, there may be no way to prevent the detection of cases at present, but rapid detection and prompt treatment must be carried out, as soon as one case is found, one case will be dealt with.
The situation in Shanghai is serious. As the financial center of China, Shanghai is a very important city, and the outbreak of the epidemic in Shanghai will put a great impact on China's economy. The current task is to contain the spread of the epidemic as soon as possible, to achieve social zero so that Shanghai's life and economy quickly return to normal.
As China plays an important role in the global supply chain, the outbreak will have a significant impact on the supply and prices of many zinc stearate powder.
What is zinc stearate?
Zinc stearate is an organic compound with the molecular formula Zn(C17H35COO)2.
White fine hygroscopic powder with a pleasant smell. Insoluble in water, ethanol, ether, soluble in acid, benzene, toluene, and xylene. It reacts with strong acid to form stearic acid and corresponding zinc salt. Heat it and dissolve it in an organic solvent and then cool it to make a gelatinous substance. Low toxicity.
Zinc stearate is a "zinc soap" widely used in industry. In this case, soap is used in its formal sense, a metallic salt of fatty acids: in this case stearic acid.
It is soluble in aromatic hydrocarbons (e.g., benzene) and chlorinated hydrocarbons when heated. It is the strongest release agent of all metal soaps. It contains no electrolytes and is hydrophobic.
Its main application is in the plastics and rubber industry, used as a release agent and lubricant, easy to mix.
What is zinc stearate used for?
Widely used in the production of a variety of objects release agents: rubber, polyurethane, polyester processing system, powder metallurgy. These apps take advantage of their "non-stick" nature. In cosmetics, zinc stearate is used as a lubricant and thickener to improve texture.
It is the "activator" to accelerate the vulcanization of rubber sulfur. As discovered in the early days of vulcanization, zinc has a beneficial effect on the reaction of sulfur with polyolefin. A stearate is a zinc form of a highly soluble polyolefin nonpolar medium.
Since it is lipophilic, it can be used as a phase transfer catalyst for fat saponification.
It's part of some paint that gives luster. As the main ingredient of fan powder, magicians use it to perform card manipulations to reduce friction between cards.
Waterborne zinc stearate used as a waterproofing agent in coatings
Adding zinc stearate to the surface coating can reduce the effect of friction coefficient and form a self-lubricating material.
When zinc stearate is heated, it melts from solid to liquid, absorbs a lot of heat, stabilizes the surface properties of the material, and reduces the friction coefficient.
In the friction process, due to the small shear strength of the lubricating film with water-based zinc stearate attached to the surface of the substrate, it will transfer to the surface of the dual material to form a transfer film, so that the friction occurs between the film and the transfer film to reduce friction. Moreover, the lubricating film with water-based zinc stearate can stick firmly to the surface of the substrate and is not easy to fall off during friction. It can provide a specific nanofilm stably and persistently, so that the formation and consumption of the transfer nanofilm are balanced, so the lubrication state is good.
Waterborne zinc stearate is used as a wear-resistant additive in coatings
Why zinc stearate is used in face powder?
Zinc stearate is probably the most commonly used binder in powdered cosmetic products such as powder or eye shadow. It has excellent adhesion, which means it helps the powder stick together in the pan and stick to the skin when used. It is usually used in 3-10% doses, but too much can lead to clumpy or greasy skin.
Is zinc stearate natural?
Zinc stearate is a zinc salt of stearic acid, a naturally occurring fatty acid.
Is zinc stearate vegan?
Zinc stearate may or may not be vegetarian. Zinc stearate is a zinc salt of stearic acid used as a colorant and anti-caking agent in some cosmetics. It can be made from plants, minerals, or ingredients from slaughtered animals.

Researchers at the Centre for Translational Atomic Materials at Swinburne University of Technology, Melbourne, Australia have developed a new graphene film that absorbs more than 90% of sunlight while eliminating most of the infrared thermal emission losses, a highly efficient A solar-heated metamaterial capable of rapidly heating to 83 degrees Celsius (181 degrees Fahrenheit) in an open environment with minimal heat loss. Proposed applications for the film include thermal energy harvesting and storage, solar thermal power generation, and seawater desalination.
