What Is It: Siloxanes are a group of chemicals that are, as the name suggests, derived from silicone. They are typically used in cosmetics and hair products to soften the skin, smooth out imperfections and moisturize an otherwise dry canvas. When it comes to caring for your mane, siloxanes not only add shine but expedite the drying process. Siloxanes are used in water-repelling windshield coatings and building sealants – it’s only natural we’d use them on our faces as well, right? Wrong.

Health Risk: The risks associated with siloxanes are far too many. Siloxanes are known endocrine disruptors that interfere with human hormone function, and could even possibly impair fertility. Research has shown that they not only cause uterine tumors, but can also skew the functioning of neurotransmitters in the nervous system. On top of that, siloxanes resist degradation and therefore pose harm to aquatic life and wildlife.

How To Avoid It: Siloxanes also go by the names cyclotetrasiloxane, cylcopentasiloxane, cyclohexasiloxane and cyclomethicone – so be on the lookout for any or all of these monikers! When it comes to siloxane-free cosmetics, we turn to Vapour Organic Beauty to get glowing without any scary side effects. And as for the care of lackluster locks?
