Ingredient Watch List: Propylene Glycol

Propylene Glycol is abosulety a bad substance to apply on skin I never use cosmetics/makeup on skin Once day I bought a product (moisturizer) for daily use (which contained propylene glycol- I was not knowing about this that time) On applying it was nice It looked like my face was moisturized and glowing The very next day morning I had cracks and wrinkles on my skin due to moisture loss

Tripropylene glycol

Vapor-phase tripropylene glycol is degraded in the atmosphere by reaction with photochemically produced hydroxyl radicals with an estimated half-life of about 3 hours Particulate-phase tripropylene glycol may be physically removed from the air by wet and dry deposition An estimated Koc of 13 suggests that tripropylene glycol will have very

Viscosity – The Physics Hypertextbook

Viscosity is normally independent of pressure but liquids under extreme pressure often experience an increase in viscosity Since liquids are normally incompressible an increase in pressure doesn't really bring the molecules significantly closer together Simple models of molecular interactions won't work to explain this behavior and to my knowledge there is no generally accepted more
