The synthetic oil
   Squalene/ C30H62
   Silicon oil


Fatty acid (part of role is surfactant)
Saturated fatty acid
   Lauric acid
   Myristic acid
   Palmitic acid
   Stearic acid
   Isostearic acid
   Behenic acid


Unsaturated fatty acid
   Oleic acid

   Cetyl myristate
   Isostearyl benzoate
   Lauryl benzoate
   Stearyl benzoate
   Proplene glycol dicaprylate
   Cety latate


Hydrophilic
The Stratum corneum in epidermis has natural moisturizing factors which help to hydrate. If the hydration is less 10%, the skin would be too dry and accelerate aging of skin. Adding humectants become a must in any kind of cosmetic and skin care products. 
Humectants could be two types.

1.      Traditional
   Propanediol/ propylene glycol/ PG
   Glycerin/ propanetriol
   Sorbititol
   1,3-butanediol
   Polyethylene glycol/ PEG
   Polypropylene glycol/ PPG
2.      NMF
   Lactic acid
   Sodium lactate
   Sodium 2-pyrrolidone-5-car-boxylate/ PCA
3.      Amino acid
4.      Polymer
   Hyaluronic acid/ HA
   Collagen
5.      Plant extract
   Plankton extract
   Silver birch extract
   Rose hips extract
   Yarrow extract

Powder
Under 300mesh (diameter is under 0.045mm)
Super micro 0.04-0.01um
1.      Cover
Top1: TiO2
Top2: ZnO
2.      Absorb fat, not absorb water
3.      Sticky
4.      Stretch
5.      Particle size
6.      Sun protection

   TiO2
   Kaolin/ china clay
   Magnesium carbonate
   Magnesium stearate
   Znic stearate
   Calcium carbonate/ CaCO3
   Znic oxide/ ZnO
   Talc/ Talcum power
   Mica/ KAL2(AlSi3)O10(OH)2
   Seritite
   Starchs
Polymeric powers

71.UVA and UVB Sun protection factor

-
Image
UVA andUVB Sun protection factor SPF is Sun Protection Factor. The number is determined experimentally indoors by exposing human subjects to a light spectrum meant to mimic noontime sun.   The SPF number only relates to UVB protection.  UVA is measured by the other definition.  UVA protection is not measured through SPF numbers.  PA is the Japanese measurement of sun protection. It is one of protection grade of UVA  . UVA is based on the Persistent Pigment Darkening (PPD) reaction reading at 2-4 hours of sun exposure.  PA is a protective level of strength to mark the three PA+, PA++ and PA+++. SPF(sun protection factor) Standard: ISO 2444: 2010 cosmetic sun protection test method in vivo determination of SPF (sun protection factor) Test by erythema Minimal dose: MED (minimal erythema dose) Process: exposure to the UV (wave length 290-400nm) Test skin type: type I~ III (ITA 0 >28 0 ) Duration: 16-24hrs after exposure UVA-PF (UVA protection factor)

79.The roles of Vitamin in skin

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 damage . The main action of vitamin C is as an
