Ever wondered why razors lubricating strips go ‘stringy’? Toxic alkaline chemicals in aerosols melt the silicone lubricating strip. Aerosols contain alkaline chemicals to create lots of foam (looks good) and blunt razors (great for profits). Check your can for isobutane, isopentane, butane (cigarette lighter gas) propane (bbq gas) sodium hydroxide (used in drain cleaners) potassium hydroxide (used in oven cleaners) Aerosols are pH 14 the same as engine degreasers....and you've been putting them on your face??
