Overview Key Applications Simply put, different types of moisturizing agents (humectants, emollient, occlusivity agent, etc.) have entirely different concepts. They are majorly used in skin care and decorative cosmetics products because these properties are very much desirable in these formulations. Overall, for any moisturizing product, the key is more what claim and consumer experience is required, not whether one needs a humectant, occlusivity agent, emollient, etc. For instance: If the face needs to remove the dryness of the skin, then a combination of humectants and keratolytic action would better achieve this. Through a 7-day mini regression study, the change can be followed and various formulations can be compared. If the legs need to remove the scaly white flakes that can be associated with dry skin, then a combination of keratolytic agents and humectancy are the primary agents to use. Including emollient will improve the initial skin feel that denotes skin softness/smoothness. If the hands have rough skin that feels tight, especially during the dry cold winter months, then a balanced combination of humectants, occlusivity agents and emollients will improve the skin's barrier to reduce the trans-epidermal water loss, while providing a soft smooth skin feel through the plasticization of stratum corneum. Moisturizing agents are used to combat dry skin, a common problem for skins of all ethnicities. Dry skin can be caused by a number of factors - from health reasons, to contamination or contact with other materials, to environmental conditions. The lack of water in the outer layer of skin (stratum corneum) causes the skin to lose its flexibility and elasticity and becomes scaly and can crack, or even bleed. The proper amount of water and sebum in the stratum corneum can prevent these things from happening. The sebum binds with the moisture in the skin and slows down the evaporation of this moisture. This action is known as trans-epidermal water loss. Creams, lotions, liquid makeups and foundations usually contain humectants and have good moisturizing properties. Thus, add moisture or assist in the retention of water in the skin. In color cosmetics, using waxes or oils in a product creates lipid barriers that keep moisture in the skin. Lipsticks and lip glosses are excellent moisturizers because they produce occlusive films when applied to the lips. Other products that form occlusive films are bath oils, suntan oils, and ointments. Chapstick is an excellent moisturizer as it creates a very good occlusive waxy film. Suppliers Brands
