What are the different uses of stearic acid?
stearic acid is saturated fatty acid, which has a huge variety of use as a ingredient in food, cosmetics and industrial products. It is extracted from many types of animal fats, vegetable fats and some oils. It is also often used to change the consistency or temperature of the product, such as lubricants or to prevent oxidation. Thanks to the versatility and cost efficiency of acid, it makes it a popular component of countless products, from candles and soap to cream and margarine. It is often used to harden the wax and strengthen the candle. It also affects the melting point of wax and improves the durability and consistency of the candle. For these reasons, this can be found in most craft stores in the candles section.
Stearic acid is also commonly used in soap production. In fact, the soap could be accidentally discovered in the ancient -year -old people who try to extract animal fat oil; This process was probably similar to how stearic acid is extracted from animal fat. SoapHowever, animal fat suffers from the disadvantage of low water solubility, which can lead to a residual film on baths and skin. Therefore, stearic acid is usually used as an additive rather than as a primary component. It can solidify soaps and give shampoos pearl color and consistency.
In the world of cosmetics, stearic acid is used to create a stable base for deodorants, lotions and creams. It helps bind and thicken the products so that they stick smoothly to the skin and have a longer life. The fact that the melting point of this acid is significantly above the human body temperature tends to prevent cosmetics from running and lane when applying for a longer period of time.
Stearic acid is also used in many food products because masonable during storage and frying. Many margarines, dissemination and shortening are also formulated with them. Although it is saturated fat, it seems to have little effect on cholesterol levels in CRVI. The reason is that its high part is converted to oleic acid, which is a monounsatuated fat.
Another use of stearic acid is the prevention of oxidation. It is usually used to stretch metal powders such as iron and aluminum, which are used in fireworks, allowing them to store for a long time. It is also used in some metal coatings to prevent oxidation and rust, which may occur on metal parts of the tools.
