What is sodium Stearate? What is the chemical formula of sodium stearate?
It is usually known as sodium stearate. The chemical structure for sodium stearate (C18H35O2) is that’s (C17H35COO), Na. It has a molecular mass of 306.46. The melting point is 250degC 270degC. white powder or white lumps soft, fatty, easily dissolves in hot water or alcoholic water, absorb moisture in the air, the solution turns alkaline because of hydrolysis.
What is sodium stearate used to do?
The main function of sodium stearate
1. Detergent: This is used to reduce foam during soap washing (sodium Stearate is the principal ingredient of soap).
2. Emulsifier or dispersant: used to emulsify polymers and as an antioxidant.
3. Protective effect on polyethylene packaging films The product is a corrosion inhibitor.
4. Cosmetics: shaving gel, transparent viscose, etc.
5. Glue: Use as an natural glue, and then paste the paper
In addition to being the primary soap ingredient in soap, sodium stearate can also be utilized as an additive in other cosmetics to form solid “stick-like” shape. Other uses for sodium stearate include dispersant for latex paint and emulsifiers. ink thickener.
Stabilizer thickener, stabilizer, and dispersant for liquid cosmetics. FDA approved flavor additives. Modifier of viscosity in gel parfum. Lubricant in nylon and polycarbonate. Production of rubber.
In addition, sodium Stearate can also be used as an additive to stabilize the polyethylene. It is extremely lubricant and has good processing properties. It is used in conjunction with zinc soap and epoxy compounds to improve thermal stability. When used alongside lead salt and lead soap in the production of hard products it may increase the speed of gelling.
Polypropylene and polyethylene can make use of sodium stearate to eliminate the negative effects of residual catalysts on the colour and the stability. It is extensively used to release and lubricate thermosetting polymers like polyolefins as well as polyester reinforced plastics.
Sodium stearate soap formula
Five thousand years ago humankind began using detergents that resembled modern soaps. Initial rough soaps were produced with natural oils and available alkaline materials (such as wood ash). The industrial revolution was when soap makers began using pure fat acids and alkalis (such as lye (sodium hydroxide or potassium hydroxide) or quicklime (calcium oxide) or slaked lime (calcium hydroxide)) to create soaps that were more refined.
Sodium stearate is the most frequently used soap fatty acid salt in the present. Vegetable triglycerides derived from coconut oil and palm oil are common sources of stearic acids raw materials. Animal triglycerides derived from tallow are also common sources. The names of stearic acid and stearic acid originate from the Greek word “tallow” and “stear”.
First, we need to determine the most important ingredient formula to make soap:
1. Oil
The main raw material in the process of saponification is oil. If you are using animal oil or vegetable oil to make soap, you are able to use a variety of practical oils, however olive oil (no flavor) is suggested. Animal oil typically uses Lard since it is readily available and inexpensive.
2. Alkali (sodium hydroxide)
Alkaline water, an aqueous mixture of sodium bicarbonate present in water is mostly used to catalyze the saponification reaction. It reacts with oil, and produces sodium stearate which is the soap that we utilize.
3. Water
It is a type of carrier that does not participate in any reaction and is typically used as a carrier of reaction for the saponification reaction.
What’s the procedure of making soap?
1. Create alkaline water by first making it, dissolve it with sodium hydroxide, and then stir until it forms alkaline water.
2. Place the alkali and oil into a fast glass/ceramic container and conduct a complete saponification reaction.
3. Take out the solid sodium stearate, which is the result of the saponification reaction and then remove any remaining reactants from other reactions.
4. Place the soap in the mold until dry. Then, turn it into soap once you’ve released the mold.
Since sodium hydroxide solution is strongly alkaline and corrosive, precautions must be taken in the process of preparation.
Is sodium stearate beneficial for skin?
The sodium stearate surfactant that is milder is more likely to cause skin irritation as compared to other surfactants. Since stearic acid is an oil that is common to fatty oils that can be found in numerous oils, there is no obvious damage to the skin. Although the quantity of animal fats is prominent, particularly butter, it’s much less than the amount of vegetable fats, but they are present. It is feasible to synthesize stearic acid into compound stearic. This makes it a sought-after ingredient in cosmetics, lubricants and other chemical raw materials. Cosmetics play a significant role in emulsification, lubrication, and. Thus, many cosmetics contain different stearic acids, provided that their concentration is within the acceptable range, they will not cause visible irritation and damage to the skin.
Does sodium stearate the same as baking soda?
Baking soda is sodium bicarbonate. The sodium stearate, referred to as baking soda is a saponified version of stearic acids. It can be made by tallow, or kokum butter. It’s used as a gelling and thickening agent as well as co-emulsifier. This white solid is the most popular soap.
Is sodium stearate natural? What is the reason sodium stearate can remove oil?
The sodium stearate is a plant soap made from coconut oil as well as palm oil. It is commonly called sodium salt and is derived from the acid stearic (a naturally occurring fatty acid naturally occurring in nature).
This is a type of salt that is a strong electrolyte. However, stearic acids contain a very large number of carbon atoms, and organic matter with a large number of carbon atoms can be insoluble in water, but soluble in organic matter, which is oil. Though sodium ions can be in the process of being ionized, the hydrophilic end of the remaining stearate groups are still present.
