Propylene glycol is in every commercial shampoo like Aloe Rid and Does nothing for hair detox
Well this is what Propylene glycol Really is .
Propylene glycol is a clear, colorless and hygroscopic liquid.
The freezing point of water is depressed when mixed with propylene glycol owing to the effects of dissolution of a solute in a solvent (freezing-point depression); in general, glycols are non-corrosive, have very low volatility and very low toxicity.
PPG is used as a surfactant, wetting agent, dispersant in leather finishing.
PPG is also employed as a tuning reference and calibrant in mass spectrometry.
PPG is used as a primary ingredient in the manufacture of paintballs.
Forty-five percent of propylene glycol produced is used as chemical feedstock for the production of unsaturated polyester resins.
Propylene glycol is also used in various edible items such as coffee-based drinks, liquid sweeteners, ice cream, whipped dairy products and soda. Vaporizers used for delivery of pharmaceuticals or personal-care products often include propylene glycol among the ingredients. Propylene glycol is used as a solvent in many pharmaceuticals, including oral, injectable and topical formulations, such as for diazepam and lorazepam which are insoluble in water.
Like ethylene glycol, propylene glycol is able to lower the freezing point of water, and so it is used as aircraft de-icing fluid.
Propylene glycol is frequently used as a substitute for ethylene glycol in low toxicity, environmentally friendly automotive antifreeze.
Propylene glycol is just a wetting agent as far as shampoo is concerned
A substance is referred to as a wetting agent if it lowers the surface tension of a liquid and thus allows it to spread more easily.
It has no special powers or abilities to break down drug metabolites. The myth came about from all the interweb pseudo scientist who as far as i can tell randomly picked it off the ingredient list of aloe shampoos assuming it must be the magic ingredient. SORRY but their is no magic ingredient its just shampoo no different than suave aloe for 4.00 .
Ask yourself this, IF PG was so special that you would pay 150.00 plus for a shampoo why not buy a whole bottle of PG from a VAP shop for 5.00 ?
AGAIN shampoos works only for people with LOW to NO use. THC requires repeat use to even get to the hair as it does not incorporate well at all. The shampoo folks also are ALWAYS part of the mac method cult who destroy your hair with crap like TIDE and bleach and god know what other random list of nonsense. ALL METHODS are made to sell scampoo.
Most the ignorant kids that say it worked online didnt need anything , they assume the joint they smoked mattered ONE TIME THC WILL NOT SHOW. If they were just barely over the threshold, ANY shampoo and yes a bunch of household item gives a %30 reduction and may get them under the wire but YOU CAN GET BETTER RESULTS form ONE SINGLE HAIR RAZOR TREATMENT than 50 aloe rid shampoo washes.
