Petrochemicals (petroleum-based ingredients):
They are low cost ingredients that are derived from the byproduct of petroleum refining. Hence they are non-renewable.
They don’t provide any benefits that can be recognized and absorbed by the skin, but they are great occlusive agents. For example, petrolatum creates an effective barrier against evaporation of the skin’s natural moisture but it may cause infection due to the trapped microorganisms. The primary health concern is the potential cause of cancer if it’s not properly refined.
Here is a list of common petrochemicals used in skin care.
PEG (polyethylene glycol) containing ingredients,
“butyl” containing ingredients: such as, Butylene Glycol, Butyl Alcohol, Butylparabend
“eth” ending ingredients: such as, Oleth, Ceteareth, Steareth, Laureth (such as Sodium Laureth Sulfate), Myreth (such as Sodium Myreth Sulfate)
DEA (diethanolamine) containing ingredients
MEA (ethanolamine) containing ingredients
“ethyl” containing ingredients: Ethyl Alcohol, Ethylene Glycol, Ethyl Acetate, Ethylene Dichloride, Ethylene Glycol, EDTA (Ethylene-Diamine-Tetracetatic Acid) and Ethylhexylglycerin
“propyl” containing ingredients: such as, Propylene Glycol, Cocamidopropyl Betaine, Isopropyl Alcohol, Propyl Alcohol
“methyl” containing ingredients: such as, Methylparaben, Methyl Alcohol, Methylcellulose
Parfum or Fragrance: up to 95% of chemicals used in synthetic fragrance can be derived from petroleum
In conventional products, they are used to provide shine and slip feel on skin. However, they are non-biodegradable, which could build-up in the environment. Here is a list of common silicones used in skin care:
