Critical micelle concentration, CMC
The characters of surfactant
 Critical micelle concentration, CMC

When there are too many surfactant molecules for the molecules to be comfortably spaced, they collect in balls called micelles with their water-hating end in the center and the water-loving end on the outside. As more water is added to a solution that contains micelles, surfactant molecule leaves the micelles if they can maintain their preferred spacing. As more water is added, there will be a point where there is just enough water so that there will be no more micelles and the surfactant molecules are tightly packed. This concentration is called the Critical Micelle Concentration or CMC.

Critical micelle concentration (CMC) is a measure of surfactant efficiency. A lower CMC indicates less surfactant is needed to saturate interfaces and form micelles. Typical CMC values are less than 1% by weight

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...

75.The relations of UV light and the molecular in the skin

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....
