(just another name for plastic!)
FUNCTION: Gives structural support to the hair.
CAUTIONARY TALE: One polymer often used, polyvinylpyrrolidine, is also used to bind the layers of wood in plywood together. Do you really want this on your hair?!
NOTE: there are natural polymers available (ex. silk, wool and cellulose).
SEEN ON INGREDIENT LIST AS: Usually petroleum
FUNCTION: Used as a carrier for the active ingredients in hairspray.
CAUTIONARY TALE: Most often ethanol alcohol is used because it dries fast (and is VEYR drying to hair) and doesn’t corrode in the can. Ethanol use has been restricted because it is a volatile organic compounds (VOCs), contributing to air pollution, and is deadly when it comes into contact with an open flame.
SEEN ON INGREDIENT LIST AS: Usually ethanol alcohol. There are no acceptable replacement solvents approved to date.
FUNCTION: Gasses, mainly butane and propane, responsible for propelling the hairspray out of the can.
CAUTIONARY TALE: Propellants have been linked to allergic skin reactions, asthma and breathing difficulties. They are highly flammable, so just think how harsh this would be on your hair if you blasted a blow dryer on hair coated with a flammable substance?
SEEN ON INGREDIENT LIST AS: propane, butane.
FUNCTION: Added to make hairspray more flexible and perform better.
CAUTIONARY TALE: Additives are just a bunch of chemicals that make the product work better, but serve no other purpose, exposing us to chemicals for no reason.
SEEN ON INGREDIENT LIST AS: Isopropyl myristate, diethyl phthalate, and silicones. (Plasticizers: added to make hairspray more flexible).
Aminomethyl propanol (AMP), ammonium hydroxide, morpholine, cyclohexylamine, borate esters). (Neutralizing and anti-corrosion agents: added to control resin solubility and help prevent the inside of the can from rusting).
