30+ Everyday Chemicals to Avoid During Pregnancy
In collaboration with NATALIST, this blog gives you a list of chemicals that should be eliminated from your environment while pregnant and where they are most commonly found. Continue on to kick those toxic chemicals to the curb and protect you, and your baby from their ill-effects.
This article was written in collaboration with Natalist, in an effort to inform and provide safer products for current and future parents.
As parents, we all strive to help our children reach their fullest potential. We send them to the best schools, feed them with the most wholesome ingredients, and foster their passions in the areas they choose. However, there is an additional way to ensure our kids stay happy and healthy, and it starts in the womb.
Chemical Exposure and Pregnancy
Research shows that many types of chemicals found in plastics and other man-made goods are linked to health risks in fetuses and infants. Two of these are called phthalates (pronounced “tha-leits”) and bisphenols. You might have heard of one type of bisphenol, BPA, the hard plastic that some reusable water bottles are made of (plastic #7). Exposures to BPA and phthalates have been linked to child behavioral issues, diabetes, and obesity.
Pregnant women would never knowingly expose their babies to harmful chemicals. Unfortunately, these chemicals are present in our everyday life and we can unknowingly expose ourselves just going about our day.
We created this handy guide for you to use to help you select the healthiest products (by category) and to minimize your exposure to toxic chemicals. These products are free of BPA, phthalates, parabens, sulfates, glycerin from non-vegetable sources, as well as other toxic chemicals specific to each category listed below.
Shampoos & Conditioners
The products you put in your hair should be free of synthetic preservatives, surfactants, emulsifiers, and chemical anti-chelating agents. Look for products free from:
Dimethicone* - a silicone-based lubricant that cannot biodegrade.
Sodium laureth sulfate - a known irritant that can also be contaminated with the carcinogen 1,4-Dioxane.6,7
Petrolatum/Petroleum jelly- may be contaminated with suspected carcinogens if not refined properly.8
Body Oils, Butters, & Lotions
Look for body oils and lotions that are free from synthetic preservatives, emollients, humectants, and surfactants. Many of these harmful chemicals are added to these products to ensure even application, smooth texture, and smooth, shiny appearance without feeling ‘sticky.’ The best products in this category should be free of these chemicals:
Butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) - synthetic antioxidants used to extend shelf life. They are carcinogenic, disrupt hormones, and can cause liver damage.9,10
Dimethicone* - a silicone-based lubricant that cannot biodegrade.
Ethylhexylglycerin - a potentiating agent often used with the preservative, phenoxyethanol, that can damage cell membrane integrity even at sub-lethal concentrations.14
Propylene glycol - a surfactant with evidence of allergic and irritant contact dermatitis as well as systemic cutaneous reactions.15,16
Soaps and Body Washes
Soaps and body washes should not contain harsh detergents, chemical preservatives, toxic pesticides, or synthetic surfactants. Common soap ingredients to avoid include:
Cocamidopropyl betaine - a synthetic detergent and surfactant that is possibly toxicant.17
Triclosan- an antibacterial chemical that is toxic and disrupts hormones.20
Formaldehyde - an antimicrobial preservative that has been linked to cancer, allergic reactions, and brain toxicity.21
Glycol ethers - a group of solvents that is often found in paint and can cause reproductive damage.22,23
Methylisothiazolinone - a preservative that is toxic and causes skin irritation, allergies, and contact dermatitis.24,25 The EU determined it is not safe for the consumer in any leave-on products.
The best options for deodorant only use natural oils, waxes, clays, minerals and astringents to help fight odor and reduce underarm moisture. Instead of using aluminum26,27, as an antiperspirant, which clogs sweat glands and impairs parathyroid function, look for options that use vegetable starches and powders to absorb the moisture. In order to fight odor-producing bacteria, try a natural deodorant that employs probiotics, baking soda, magnesium, zinc and/or charcoal.
Compared to other personal care products, lip balms do not need many chemical additives in order to do its job. Simple moisturizers and conditioners, such as coconut oil, shea butter and beeswax, work effectively as lip treatments. For this reason, most lip balms marketed as ‘natural’ are less likely to be contaminated with chemicals such as parabens or parfum/fragrance.
That being said, you still want to double check that your lip balm is free of:
Petroleum jelly - may be contaminated with suspected carcinogens, such as PAHs, if not refined properly.28
Butylated hydroxytoluene (BHT) and butylated hydroxyanisole (BHA) - synthetic antioxidants used to extend shelf life. They are carcinogenic, disrupt hormones, and can cause liver damage.29,30
Common sunscreens not only contain chemicals specifically engineered to combat UV radiation but also chemicals that plague many commercial lotions for smooth application. Look for a sunscreen option that is free of:
Oxybenzone - UV ray absorber linked to hormone disruption.37,38
Para-Aminobenzoic Acid (PABA) - UVB filters that can alter endocrine activity.41,42
Hair Styling Products
Hair styling products may contain preservatives, thickeners, foaming agents and/or fragrance that are contaminated with toxic impurities. Avoid these ingredients:
Triclosan - an antibacterial chemical that is toxic and disrupts hormones.43
Formaldehyde and formaldehyde-releasing substances - an antimicrobial preservative that has been linked to cancer, allergic reactions, brain toxicity.44
Cyclopentasiloxane - a silicone lubricant solvent that cannot biodegrade and is particularly toxic in aerosols.45
Dimethicone* - a silicone-based lubricant that does not biodegrade.
PVP/VA Copolymer* - a synthetic vinyl polymer used as a binder; the CIR (Cosmetic Ingredient Review) states it is not toxic, however Australia’s National Industrial Chemical Notification and Assessment Scheme has found hazardous impurities.46
Polyethylene glycol (PEGs) - a silicone thickening agent that can be contaminated with carcinogenic impurities and by-products, such as ethylene oxides and 1,4-dioxane.47
Toothpaste and Mouthwash
Avoid toothpastes/powders and mouthwashes that contain fluoride, artificial sweeteners, coloring agents, harsh abrasives, thickeners, or surfactants. The packaging tubes and bottles should also be BPA-free. When looking for a toothbrush, make sure it does not contain BPA or phthalates in either the bristles or the handle. Overall, these are the ingredients to avoid in oral care products:
Fluoride* - See discussion under “Watch List” below.48
Saccharin* - an artificial sweetener that has been linked to bladder cancer.
Sorbitol* - an artificial sweetener that keeps toothpaste from drying out, but is also a laxative.
Triclosan- an antibacterial chemical that is toxic and disrupts hormones.49
Carrageenan*- although extracted from seaweed, there is conflicting evidence about whether food-grade carrageenan can cause gastrointestinal complications.50,51
Propylene glycol - a surfactant with evidence of allergic and irritant contact dermatitis as well as systemic cutaneous reactions.52,53
Sodium Lauroyl Sarcosinate* - a synthetic surfactant that can break down into cancer-causing chemicals, such as nitrosamines.54
Cocamidopropyl betaine - a synthetic detergent and surfactant that is possibly toxicant.55
Hydrated Silica* - abrasive particles added to toothpaste to polish and whiten the teeth; the same particles commonly found in “Do Not Eat” packets.
Million Marker has inspected dozens of products to create a list of Approved Products that don’t contain the ingredients listed above. Products have been cross-checked with health and environment databases such as the Environmental Working Group (EWG), Environment Canada Domestic Substance List, MadeSafe, and Campaign for Safe Cosmetics’ web list. Million Marker errs on the side of caution when evaluating these ingredients given the lack of safety data and scientific evidence. For this reason, we still lend weight to substances supported by case-studies or studies with small sample sizes. We update our list according to the newest research and strive to be transparent with the findings. Check out the Approved Products list here.
