What is Moisturizing Ingredients commonly used in cosmetics?

First, the quality of cosmetics depends on moisturizers. Second, one of the basic substances that constitute cosmetics is moisturizers, which are necessary in all cosmetic formulations. Moisturizer by maintaining and absorbing moisture, play a moist, moisturizing effect, can effectively restore skin elasticity. A moisturizer is a hygroscopic compound that is capable of absorbing moisture from moist air.

Lock water It is mainly closed oil, which slows down the moisture distribution in the skin and cannot directly provide water to the skin. It include mineral oil (petroleum jelly, white oil, etc.), synthetic oil (GTCC, 2 EHP, etc.), vegetable oil (shea fruit oil, grape seed oil, etc.), animal oil (lard, etc., less vegetable oil)

biological regulation

It mainly regulates the water absorption energy of cells and the lipid barrier structure between cells. The components belonging to this category are ceramide, cholesterol, free fatty acid, triglyceride and squalene.

Membrane moisturizing

This kind mainly has polysaccharide polymer moisturizer, aqueous solution expansion, combined with a lot of moisture, soft film effect, generally will not absorb the moisture in the skin, belong to this kind of ingredients have sodium hyaluronate, pululan polysaccharide, tremella polysaccharide, etc.

Types of moisturizers

Closed oil

Such oils do not directly provide moisture to the skin, But forms a tight waterproof film on the skin, Prevent skin moisture from evaporation outside, The commonly used closed oils are mainly divided into mineral oils (petroleum jelly, white mineral oil, microcrystalline wax, etc.), Synthetic oils (squalane squalane, lanolin derivatives, polysiloxane, fatty acid, fatty alcohol, fatty acid lipid, etc.), Vegetable oils (olive oil, coconut oil, castor oil, cottonseed oil, soybean oil, sesame oil, almond oil, peanut oil, corn oil, rice bran oil, tea seed oil, avocado oil, stone nut oil, European nut oil, walnut oil, cocoa oil, butter), Animal grease (mink oil, egg yolk oil, lanolin oil, lecithin, etc.)

New, highly effective moisturizer

It maintains the water content of the cuticle by regulating the water absorption of horn cells and the lipid barrier structure between cells. This regulation function requires the participation of biological reactions. The new efficient moisturizing agent mainly includes ceramide, cholesterol, cholesterol ester, squalene and triglyceride.

Introduction of commonly used moisturizer

• xylosic alcohol

Add xylitol to cold cream, snow cream, moisturizer and other cosmetics, add the amount is in 3% to 6%. Xylitol belongs to a mild moisturizer, which is a white crystal with slight sweetness. Its application and cosmetics make cosmetics have good moisturizing and moisturizing effect.

• sorbic alcohol

Sorbitol is the most commonly used cosmetic moisturizer, its hygroscopic properties is less than glycerol. Because of its cool and refreshing sweet taste, also known as cool tea alcohol. Sorbitol can improve the cold resistance stability of the product and has excellent freezing resistance.Sorbitol is well suitable as a moisturizer in baby products or toothpaste because of its non-stimulating effect on the skin and oral mucosa.

•  Silk peptide

The structural unit of filopeptide is amino acid, which is a natural silk hydrolysis product.  Moreover, silk peptide also has the effect of skin loss repair, eliminate wrinkles, fade melanin, promote skin tissue regeneration, skin nutrition and so on.  

• chitin

Chitin is a high polymer, because it is an amorphous translucent white substance, also known as chitin, chitin.  Chitin derivatives are easy to blend with cosmetics formula, which has non-greasy, fresh skin feeling, molding ability and excellent moisturizing performance. Mainly in hair care products, essence, lotion, skin cream application.

• hyaluronic acid

At present, the best moisturizing substance in nature is hyaluronic acid, which is called natural moisturizing factor. With the development of biochemical technology, the application of hyaluronic acid in cosmetics greatly reduces the use cost, with good safety and high purity. As a moisturizer, the biggest advantage of hyaluronic acid is its lubricity and film formation. After the skin is exposed to hyaluronic acid, hyaluronic acid will combine with water to form a breathable hydration elastic film

• propanediol
  Propylene glycol can be used in hair dye, foam bath agent, conditioner, shampoo and other skin care cosmetics, its no sensitization, irritation, good safety, good use effect, lasting moisturizing effect, low sticky feeling, refreshing, moisturizing performance is relatively mild.
• Glycerol

In cosmetics, the most common application, and the earliest application of the moisturizing agent is glycerol, glycerin is sweet, odorless, transparent, colorless viscous liquid, its chemical name is also called propylene glycol.
