If you are on the fence about “natural” cosmetics vs. additives used in “non-natural” products, read on. I have compiled a short list of ingredients that are both used in traditional cosmetics, but are also used for industrial applications (machines and furniture cleaner, etc).
I’m not saying everyone should use 100% natural products, but you should also be educated about what you are putting on your skin. Here is a list of my top 5 ingredients that I always make sure the skincare I use is free of. After all, I don’t want ingredients that are used in Liquid Wrench on my skin. Do you?
Isopropyl Myristate
Isopropyl Myristate is a synthetic oil used as an emollient, thickening agent, lubricant or moisturizer in beauty products. It is most often seen in aftershaves, shampoos, bath oils, antiperspirants, deodorants, and various creams and lotions (Source). Although it is a popular ingredient, in more than 5% of formulations it can cause skin irritation and clog pores; for this reason, it is considered a comedogenic and is aggravating to acne. it is also an ingredient in a well-known rust remover, Liquid Wrench
Propylene glycol
Propylene glycol is widely used as a vehicle for topical medicines, cosmetics, lotions, and antiperspirants. In addition, it is widely used in industry in automotive brake fluid, in antifreeze formulations, and as a humectant for tobacco formulations, as well as in the food chemical industry as a solvent for food colors and flavorings. Valium contains 40% propylene glycol.
Petroleum
Petroleum, or crude oil, is recovered mostly through oil drilling. It is refined and separated into a large number of consumer products, from petrol and kerosene to asphalt and chemical reagents used to make plastics and skincare. Petroleum is used in manufacturing a wide variety of materials, and it is estimated that the world consumes about 88 million barrels each day. The use of fossil fuels such as petroleum can have a negative impact on Earth’s biosphere, releasing pollutants and greenhouse gases into the air and damaging ecosystems.
Propylene glycol
Propylene Glycol is a colorless, ordorless liquidis mainly used as antifreeze for water systems and heaters because it is less toxic. It gives off fumes in smoke machines and serves as vaporizable base for diluting nicotine liquid in electronic cigarettes. Moreover, it is added to other household items like furniture polish and glass cleaners. Photographic chemicals use propylene glycol as a solvent as well.
Propylene Glycol is known to exert high levels of biochemical oxygen demand (BOD) during degradation in surface waters. This process can adversely affect aquatic life by consuming oxygen aquatic organisms need to survive. Large quantities of dissolved oxygen (DO) in the water column are consumed when microbial populations decompose propylene glycol.
Sodium Lauryl Sulfate
SLS is mainly used in detergents for laundry with many cleaning applications. SDS is a highly effective surfactant and is used in any task requiring the removal of oily stains and residues. It is found in higher concentrations with industrial products including engine degreasers, floor cleaners, and car wash soaps, and has been shown to irritate the skin of the face with prolonged and constant exposure. A study suggested SDS in toothpaste caused the recurrence of aphthous ulcers, commonly referred to in some countries as canker sores or white sores.
