40.Ionic and Non-ionic surfactant

Ionic and Non-ionic surfactant
Skin care products and cosmetics need to add surfacant as well. 
There are many types surfactants. They have different characters. 
The surfactant could be divided into two groups
1.      Ionic surfactant
The ionization has three types
Anionic surfactant
RCOO-Na+
RC6H4SO3-Na+
a.  Cationic surfactant
RNH3+Cl-
RN(CH3)3+Cl-
b.  Amphoteric surfactant
R+NH2CH2COO-
RN+(CH3)2CH2CH2SO3-
The Amphoteric surfactant is milder and fewer toxicities than anionic surfactant. It most is made of shampoo and baby products.
2.      Non-ionic surfactant
water soluble functional group won’t ionize. It would exist as -OH,- O-,- CONH-, -COOR types. It also could combine with different HLB values of non-ionic surfactants.
RCOOCH2CHOHCH2OH

RC6H4(OC2H4)nOH

The roles of Vitamin in skin As we know, the chemical changes induced by exposure to sunlight, we should be able to design a cosmeceutical regime to combat photodamage and reverse its effects. Vitamin molecules are the options and have the functions of metabolism, antioxidant and preventing free radical. 1.       Metabolism Vitamin A controls the conversion of pre–matrix metalloproteinases secreted by keratinocytes and fibroblasts into active matrix metalloproteinases, but with a deficiency of vitamin A, UV irradiation stimulates the unimpaired release of metalloproteinases that then destroy collagen and the anchoring fibrils. Without vitamin A, the rete pegs become flattened. Lang erhans cells need vitamin A to function, but if the vitamin A is inactivated by light, then they cannot function properly and recognize cells whose DNA has been damaged. 2.       Antioxidant Deficiencies of vitamin C permit more free radical ...

The surfaces of our skins will influence the first sight. The surfaces of our skins are composed some features by visual observation. They are cristae cutis, skin ridge, sulci cutis, line, wrinkle, fold, nevus, mole, spot, and pores.   The light will reflect, diffuse and be absorbed through surfaces of skins. The results of light shining are the aspects of beauty. That’s why people apply makeups and cosmetics.  ------------------------------------------------------------------------------------------------------ find the specific skincare product ingredients by "glamskin" App
