Moisturizers are a type of hydrophilic emollient substances. They have the ability to bind water in the low humidity range and replenish moisture to the skin. They can maintain the skin in a balanced state higher than normal water content by controlling the exchange of moisture between the product and the surrounding air, thereby alleviating dry skin.
There are countless formulas for moisturizers, and different combinations of ingredients can make many good moisturizers. A good moisturizer must not only moisturize during the day but also have a sun protection function. In addition to protecting the skin from the sun, it must also contain lubricants, water-retaining ingredients, anti-allergic ingredients and antioxidants.
Among them, Lubricants are lubricating ingredients that can prevent dry skin from drying out and provide what dry skin lacks. Lubricating ingredients are the basic components of moisturizing and are the source of the moisturizer’s feel. Lubricants are similar to the lubricants produced by the skin. Commonly used lubricants include vegetable oil, mineral oil, African nut oil, cocoa butter, petroleum jelly, cholesterol and animal fats (lamino oil is most similar to the oils produced by human skin). It is good for the skin and is the ingredient that is easier to identify on the label. Ingredients that are less easy to identify on the label, such as palmitic acid, myristic acid, and stearic acid, are waxy substances that provide the gentle touch of moisturizers. .
Today I will give you a brief introduction to the ingredients in these moisturizing lubricants that are difficult to identify:
Palmitic acid:
Also known as hexadecanoic acid and palmitic acid, it is A saturated higher fatty acid, a colorless, odorless waxy solid. Insoluble in water, slightly soluble in petroleum ether, soluble in ethanol, easily soluble in ether, chloroform and acetic acid. It is widely present in nature, and almost all oils contain varying amounts of palmitic acid components. It is a raw material for creams, lotions, surfactants and oils.
Myristic acid:
Alias fourteen Acid, tetradecanoic acid, is a white to yellowish-white hard solid, occasionally a shiny crystalline solid, or a white to yellowish-white powder, odorless. Insoluble in water, soluble in anhydrous ethanol, methanol, ether, petroleum ether, benzene and chloroform. It can be used as a raw material for soaps, soaps, detergents, cosmetic surfactants and chemical fiber oils; it can be used to manufacture emulsifiers, waterproofing agents, curing agents, polyvinyl chloride heat stabilizers and plasticizers, etc. It is also a raw material for spices and medicines. .
Stearic acid:
Alias eighteen Stearic acid, stearic acid, and fat wax are a type of fatty acid widely found in nature. Almost all oils contain stearic acid in varying amounts. The content in animal fats is relatively high. For example, the content in butter can reach 24 %, the content in vegetable oil is less, tea oil is 0.8%, palm oil is 6%, but the content in cocoa butter is as high as 34%. It is an indispensable raw material for dairy cosmetics and is commonly found in creams and lotions. It is mainly used for emulsification in skin care products such as snow cream and cold cream, thereby turning it into a stable and white paste. Stearic acid is also the main raw material for manufacturing almond honey and milk.
