It helps prevent the polish from becoming brittle and also served as solvent for dyes.The chemical is banned from cosmetics in the European Union, and was added to California’s Proposition 65 as a suspected “teratogen” (something that causes congenital abnormalities) in 2006. The U.S. also banned it from being used to make children’s toys in 2008, but it’s still allowed in nail polishes.Researchers confirmed that DBP is absorbed through the skin in a 2007 study. In addition to being linked to developmental problems, it’s also believed to be a hormone disruptor, to impair fertility, and to be toxic to aquatic organisms.

Dimethicone:

A silicone oil that is very popular in today’s personal care properties.the covering and trapping property of dimethicone means that it’s not just trapping moisture, but bacteria, skin oils, sebum, and other impurities. That means those prone to acne or with oily skin are more likely to see increased blackheads and breakouts when using products containing this ingredient. It is also bad for the environment since Dimethicone is non-biodegradable.

are ingredients that are synthetically produced using ethylene oxide – a known carcinogen. These new chemical compounds are known as ethoxylated compounds. A by-product of this process is another chemical known to be harmful: 1,4 dioxane. Also, the chemicals listed below are all produced using this process of ethoxylation and, as a result, are contaminated with 1,4 dioxane. To avoid ethoxylated compounds look for these ingredients listed on labels:

– Butoxyethanol: Synonyms: Butyl cellosolve; Ethylene glycol mono-n-butyl ether; Ethylene glycol monobutyl ether; EGBE; Dowanol EB; Butyl oxitol; Jeffersol EB; Ektasolve EB

– Ethanolamines (DEA/TEA/MEA/ETA)

Found in: shampoo, body wash, bubble bath.

Glycols:

Specifically Propylene Glycol and Butylene Glycol. (The other glycol “polypropylene glycol”, also known as PEG, is an ethoxylated ingredient and is included on our Dirty List). Propylene and Butylene Glycol are synthetic chemicals derived from petroleum compounds and are used mostly to attract moisture to the skin, as well as condition the texture of the product to keep it from separating. The Cosmos Standard in the EU accepts Propylene and Butylene at small levels and there is not enough research to document major concerns. One thing we are aware of however is that these two glycols may increase the skin’s ability to absorb, meaning if the product contains anything in it that may be potentially irritating the glycols would increase their absorption.

Heavy Metals:

You’ll never actually see these ingredients listed, but they occur at trace levels in some pigments that are mined, like micas. We trust that our vendors who use mineral-based pigments have procured them from trusted sources and can verify they don’t contain concerning percentages. It’s for this reason that the FDA regulates color pigments, to protect the consumer from exposure to high dosages of heavy metals. We follow the FDA approved guidelines for regulated pigments and ask that our vendors verify that if they use FD&C colors that they can trace the source and assure their colors are within FD&C accepted parameters. All products must meet the minimums established by FDA for cosmetics for residues of: Mercury & Mercury Compounds, Lead, Arsenic, Cadmium.

Hydroquinone:

a skin-lightening chemical that inhibits the production of melanin and is linked to cancer, organ toxicity, and skin irritation.

Petrolatum – Petrochemicals:

You will rarely see “petrolatum” listed anymore. However its by-products are often listed. We’ve included a list of a few glaringly concerning petroleum derivatives below. But sometimes, petroleum is actually listed, but clever marketers will disguise the name, we’ve tried to include all of the synonyms below. Contaminants from hydrocarbons, and the processing of crude oil: Toluene, Hexane, Mineral Oil, Paraffin Wax, Benzene, Mineral oil, Liquid paraffin.

Japan has banned the use of phenoxyethanol in all cosmetics, while most other countries have limited the use of it to 1% concentration. Can cause allergy like Eczema and may have nervous systems effects on infants. Found in: perfumes and soaps.

Phthalates:

The State of California and the EU have classified dibutyl phthalate (DBP) as a reproductive and developmental toxicant; exposure to DBP during gestation causes infertility, cryptorchidism and problems in sperm development, adverse effects similar to human testicular dysgenesis syndrome. Prenatal exposure to DBP has been associated with anatomical changes in the reproductive system development in baby boys. In adult men, DBP has been correlated with changes in serum hormone levels, lower sperm concentration and motility, and decreased fertility. (DBP, DEHP, DEP and others): a class of plasticizing chemicals used to make products more pliable or to make fragrances stick to skin. Phthalates disrupt the endocrine system and has been found to cause birth defects and impact reproductive systems. Found in: synthetic fragrance, nail polish, hairspray, and plastic materials.

Polyacrylamide:

is used to stabilize products and bind ingredients. It can break down into acrylamide which has been shown to be a carcinogen and has been linked to cancers of the thyroid, uterus, mammary glands, and others in animal studies. Daily exposure to acrylamide through cosmetic products can be compared to the amount one is exposed to when smoking a pack of cigarettes a day (https://www.ncbi.nlm.nih.gov/pubmed/21822324). Found in: moisturizers, anti-aging products, hair products, and others.

PEG-100 Stearate:

Resorcinol:

a colorant and fragrance ingredient that is a skin irritant, toxic to the immune system and organs, and suspected to cause hormone disruption. Resorcinol and 2-Methylresorcinol: also listed as 1,3-benzenediol, resorcin, 1,3-dihydroxybenzene(m-hydroxybenze, m-dihydroxyphenol) are mostly exclusively used in hair dyes, to help the color bond to hair shaft, which are a category of products we don’t sell at Credo. Occasionally however they may creep into acne treatments to help smooth scaly, uneven skin. The main concern with these chemicals are their actions as colorants. The EU, Japan and even the US has restricted their use.

Silicones:

You will mostly find them listed as dimethicone, cyclomethicone, cyclopentasiloxane, or ingredients ending in “cone” – and they are included as an ingredient to adjust the texture, make the skin feel smooth, fill in wrinkles, and add shine and glow. There really isn’t enough research to identify this synthetic chemical as cause for concern for human health, but there are a few things about it that we thought we’d let you know so you can make an informed decision: 1) It is a totally synthetically manufactured chemical, not derived from plants 2) It’s has been shown to bio-accumulate, meaning it does not biodegrade and may cause environmental damage 3) It is an occlusive, meaning it will clog pores. So if you are acne prone, it may be best to stay away from products that list this as an ingredient.

Sodium Lauryl Sulfate and Sodium Laureth Sulfate (SLS and SLES):

SLS and SLES are surfactants that can cause skin irritation or trigger allergies. SLES is often contaminated with 1,4-dioxane, a byproduct of a petrochemical process called ethoxylation, which is used to process other chemicals in order to make them less harsh. Found in: shampoo, body wash, bubble bath.
