What is Vegan Magnesium Stearate?

Magnesium stearate is a compound with the chemical formula Mg(C18H35O2)2. It is a salt formed by stearic acid (a long-chain fatty acid) and magnesium ions. Magnesium stearate is often used as a magnesium supplement. It has properties such as acid resistance, stability and lubricity, and is widely used in medicine, cosmetics, food and other fields.

Vegan Magnesium Stearate Uses

Vegan Magnesium Stearate is a versatile ingredient used in various industries such as perfume powder, cosmetics, and as a drying agent for paints and lacquers. It is also utilized as a heat stabilizer for polyvinyl chloride and as a raw material for cosmetic flour, emollient ointments, and pharmaceutical tablets. In the school wood powder industry, it is used to create lubricated, bright, and transparent products. Additionally, it serves as a transparent flattening agent in the paint industry.

Metal soaps, which are used as stabilizers for polyvinyl chloride, are typically higher fatty acid salts of cadmium, barium, calcium, zinc, and magnesium. These metal soaps have varying properties depending on the type of metal and acid radicals present. For example, cadmium and zinc soaps exhibit good initial heat resistance, while barium, calcium, magnesium, and strontium soaps have good long-term heat resistance. The weather resistance of these metal soaps also varies, with cadmium, zinc, lead, barium, and tin soaps being more resistant.

In terms of processability, lead and cadmium soaps offer good lubricity, while barium, calcium, magnesium, and strontium soaps have good gelling properties. It is important to note that lead and cadmium soaps are highly toxic and can cause sulfide pollution. On the other hand, calcium and zinc soaps are commonly used in non-toxic formulations.

Magnesium stearate is considered non-toxic and is included in various pharmacopoeias, including the Chinese Pharmacopoeia. It is approved for use in food-contact products in countries such as the United States, Germany, and Japan. These regulations specify the acceptable levels of magnesium content, moisture, heavy metals, iron, sulfate, and chloride content in products containing magnesium stearate.

Vegan Magnesium Stearate Content Analysis

Accurately weigh about 1g of the sample, add 50ml of 0.1mol/L hydrochloric acid, and boil for about 30 minutes, or until the precipitated fatty acid layer is clear. If necessary, add water to the original volume. Cool, filter, and rinse the filter and filter residue with water until the eluate is no longer acidic to litmus. Neutralize the filtrate with 1 mol/L sodium hydroxide solution until the litmus becomes neutral. Under full stirring with a magnetic stirrer, perform the following titration with 0.05 mol/L ED] limited disodium: first add 30 ml of titration solution from a 50 ml burette, then add 5 ml of ammonia/potassium chloride buffer test solution (TS-12) and Wool Chrome Black test solution (TS-97) 0.15ml, and then continue titration to the blue end point. Each milliliter of 0.05mol/L ED-TA disodium solution is equivalent to MgO2.015mg.

Vegan Magnesium Stearate Production Method

It is refined by combining magnesium oxide with food-grade solid mixed fatty acids (mainly stearic acid). Or saponify stearic acid with sodium hydroxide to obtain sodium stearate, and then metathesize with magnesium sulfate to obtain magnesium stearate. Add stearic acid and water to the reaction pot, heat to 85°C, stir and dissolve, then slowly add sodium hydroxide solution preheated to 75°C. After the saponification reaction is completed, control the temperature at 72°C, and slowly add the magnesium sulfate solution preheated to 55°C while stirring. After metathesis, the water is centrifuged and the filter cake is washed with water until the sulfate radicals meet the requirements, then dried, air-dried, and sieved to obtain the finished product. The yield of stearic acid is 100%.
