A 2016 review by the European Food Safety Agency (EFSA) concluded that oral absorption is approximately 70% in rats, about 50% in dogs and ≥ 88% in humans, and that SAIB as used as a food additive (or, presumably, in similar levels in cosmetics) is not a safety concern. This chemical has been linked to liver toxicity in rats, but a human study found no ill effects when volunteers ingested 20 mg per kg of body weight per day for two weeks. It hasn’t been associated with any adverse health effects in humans, but very little study has been done on this ingredient. Pentylene glycol is a synthetic, low molecular weight solvent and skin-conditioning agent. So, avoid if you’re concerned you’re sensitive to this chemical, but don’t worry too much otherwise. Propanediol is found in many lipsticks and may cause irritation in some sensitive folks but isn’t toxic to humans or the environment. Some are more toxic than others, so if you’re going to choose a lipstick containing these, check every color number with the Environmental Working Group first. FD&C and D&C colorsĭerived from bituminous coal (coal tar), these colors can be carcinogenic and are tested on animals. Companies like Ecco Bella have replaced talc with a mixture of natural clays and minerals, cornstarch, and flower wax-coated pigments. Similar in composition to asbestos, and a known carcinogen, talc is often used as a base in cosmetics.
SLIGHT BLUE TINGE TO LIPS HOW TO
Let’s quickly go through some of the key chemicals to watch out for in lipsticks and how to spot them.
Indeed, the US Food and Drug Administration bans certain ingredients from use in lip products because of the increased risk of ingestion compared to, say, an eyeshadow or blush. Most conventional lipsticks contain petroleum-derived chemicals, potentially toxic FD&C and lake dyes, synthetic ‘fragrance’ and preservatives, and other ingredients that may have adverse health effects. Are these ingredients safe and eco-friendly, or downright toxic to you and the environment? As always, it’s a mixed bag for conventional cosmetics. If you’ve ever read the tiny print on the side of lipstick packaging, and you don’t have a chemistry degree, you’ve probably felt your eyes glaze over at the list of chemicals. But, as with so many things for LeafScore, my research into this topic has me excited about lipstick again! Why? Because I found some gorgeous, truly non-toxic natural lipsticks from super sustainable, eco-friendly, safety-minded folks.
These days, I’m far more likely to pout about the greenwashing afoot in the cosmetics industry than to actually use lipstick to create the perfect pout.
