The applications of surfactants

The applications of surfactants
There are four kinds of surfactants which can decrease the surface tension of interface in the cosmetics and skin care products. They are anionic surfactant, cationic surfactant, amphoteric surfactant, and nonionic surfactant. The cosmetics and skin care products add surfactants for different functions as the following.   

Emulsifier: anionic surfactant, nonionic surfactant
Detergent: anionic surfactant, cationic surfactant, amphoteric surfactant
Blowing agent: anionic surfactant, amphoteric surfactant
Thickening agent: amphoteric surfactant, nonionic surfactant
Bactericidal agent: cationic surfactant
Solubilizer: nonionic surfactant
Antistatic agent: cationic surfactant, amphoteric surfactant

Wetting agent/ humectant: nonionic surfactant

76.factors for skin damage(1)

-
Image
There are many factors that cause skin damage. How does the damage result? They may be from the UV light, pollution , and so on. For example, photoaging and free radical. Then the cells are influenced.   photoaging Sunlight will cause phtoaging. Chronically irradiated skin is metabolically hyperactive, thus giving rise to epidermal hyperplasia and neoplasia , increased production of elastic fibers (solar elastosis), accelerated breakdown and synthesis of collagen , and enhanced inflammatory processes. If DNA damaged and a mutation occurs in the gene, the keratinocytes may lose their ability. Free radical and antioxidants Stratum corneum is frequently and directly exposed not only to UVR but also to other outside forces such as air pollutants, chemical oxidants, smoking, and microorganisms . They are the resources of free radicals . If the protection is insufficient, oxidative damage may occur . Then the chronic accumulation of such deviated cell components may result i...

The relations of UVlight and the molecular in the skin How do light damage skin? Light consists of a spectrum of photons which contain energy that vary according to the wavelength.  The light interacts on the molecular and then changes their chemical structure or on the subatomic level by creating free radicals. Otherwise, not only UV light but also green, blue, and violet light can damage cells. A photon’s energy can be absorbed into the molecule which is then altered. As the absorption of energy, it can also result in electron changes with the generation of free radicals. A free radical is in fact simply an atom with an unpaired electron that starts up a destructive concatenation of chemical reactions. It may end up causing damage in the cell membranes or in the DNA of the cell. The following are the reaction after exposure to UVB, UVA, and blue light. The influence of increased free radical activity DNA strand breaks occur from increased free radical activity....
