Humectants!
Frequently Humectants are used in the cosmetics. They are used for two purposes,
1. The Humactants hold moisture and absorb moisture from the atmosphere and therefore they inhibit the drying out of the products and therefore humectants are added to the cosmetic formulations.
2. Humectants when are added to the cosmetics, they help increasing and maintaining moisture in the skin and hair.
Humectants are widely used in the cosmetics like lotions, skin creams, sun screens, moisturizers, shampoos, conditioners, cleansers and may a times also in the soaps. Humectants are the hygroscopic moisturizers and work by attracting water to the upper layer of the skin.
All the humectants are characterized by the presence of the hydroxyl group, which helps them to participate in the hydrogen bonding which makes them absorb water. This process absorbs moisture from the outer layer of the skin or from the moisture when the humidity of the atmosphere is high.
The water holding capacity of different humectants differ in the way that the water binding capacities vary in different humidity’s. Commonly used humectants include :
Glycerin
Hyaluronic acid
Propylene glycol
Butylene glycol
Sodium PCA
Sorbitol
Allantoin
Most popular humectant is Glycerine.
Also I must add few important functions performed by the humectants. Many a times they play a major role in attracting the moisture from the dermis into the epidermis, thereby increasing the water content of the epidermis. This is the major way they hydrate the epidermis, and they can attract moisture from the atmosphere only when the humidity in the atmosphere is more than 70 percent.
Above holding the moisture in the skin, the humectants also provide pliability and flexibility of the skin, and prevents cracking of the skin. Humectants also help reducing the skin irritation caused by the dryness of the skin.
Another important work performed id, it prevents the external chemicals from contacting the dermis.
We are using classic range of humectants in most of our cosmetic products for the betterment of skin and hair.
