Many ingredients don't make the cut with our products.
Over 10,000 ingredients don't make the cut.
Our published Banished List represents a small fraction of the harmful ingredients banned from use in any Crunchi product. If we were to list every single ingredient we prohibit it would be ever-growing and easily reach into the tens of thousands.
Our Banished List includes 50 of the worst offenders and most commonly found ingredients used in conventional cosmetics, as well as many products marketed as "natural" or "clean".
1, 4-Dioxane
A contaminant that is not required to be listed on an ingredient label in the US. It is a by-product of the ethoxylation process in which carcinogenic ethylene oxide is reacted with other ingredients to make them less harsh on the skin. The EPA (U.S. Environmental Protection Agency) has classified 1,4-dioxane as likely to be carcinogenic to humans. The FDA studies showed that 1,4-dioxane can penetrate human skin. 1,4-dioxane can be reduced or removed from a product through the vacuum-stripping process. However, independent tests show that many manufacturers fail to do so.

2-Bromo-2-Nitropropane-1,3-Diol (Bromopol)
An antimicrobial preservative that slowly releases carcinogenic formaldehyde into a product over time (see Formaldehyde). People may develop a contact allergy to formaldehyde or to the ingredient itself. The American Society of Contact Dermatitis lists 2-bromo-2-nitropropane-1,3-diol as one of the allergens even in concentrations as low as 0.5%. In the presence of amines (such as triethanolamine, diethanolamine, and morpholine) in a product, 2-bromo-2-nitropropane-1,3-diol can form nitrosamines, which can penetrate the skin and increase the risk of cancer. Longer storage times and higher temperatures increase the amount of formaldehyde released from 2-bromo-2-nitropropane-1,3-diol, which can lead to higher risks of health problems.

Benzophenones are photostabilizers used in cosmetics. Photostabilizers have a photoprotective effect on the skin. In 2012, benzophenone was added as a carcinogen to the California EPA’s Proposition 65 List of Chemicals Known to the State to Cause Cancer or Reproductive Toxicity. The evidence linking the benzophenone chemicals to endocrine disruption is complex, and studies show that different benzophenones may have difference hormone-disrupting effects. Because they commonly cause contact allergic dermatitis, benzophenones were declared the Contact Allergen of the Year for 2014 by the American Contact Dermatitis Society (ACDS).

Mercury & Mercury Compounds
(Additional Names: Thimerosal)
Mercury and Mercury Compounds are used as a preservative in vaccines and cosmetics. According to the Federal Food and Drug Administration (“FDA”), mercury compounds are readily absorbed through the skin and accumulate in the body, increasing risks of various adverse health effects including the disruption of the nervous system. They may also cause allergic reactions and skin irritation. Mercury is considered particularly toxic to the developing brain during pregnancy, infancy and childhood. The FDA has banned the use of mercury compounds in all cosmetics except those used around the eyes, where levels are limited to 65 parts per million (ppm).

Nanoparticles (Nanomaterials)
(Additional Names: nanomaterials)
Particles of cosmetic colorants, preservatives, and UV-filters (zinc oxide and titanium dioxide) of a very small size, ranging from 1 to 100 nm. The main concerns about them in cosmetic products are the possible translocation to viable skin cells and, as a result, its potential to damage DNA, which may lead to cancer. Recently, German researchers found that particles with a diameter of more than 20 nm can be considered safe, as they do not reach viable cells in the epidermis of healthy skin. The European Union requires nanomaterials to be labelled in the list of ingredients with the word 'nano' in brackets.

PEGs (Polyethylene Glycol)
A group of ingredients with the prefix “PEG-” followed by a number. They are made by the process of ethoxylation in which carcinogenic ethylene oxide is reacted with other ingredients to make them less harsh on the skin. As a result of the ethoxylation process, 1,4-dioxane is created and can be left behind in the product. 1,4-dioxane can be reduced or removed from a product through the vacuum-stripping process. But independent tests show that many manufacturers fail to do so. The U.S. Environmental Protection Agency (“EPA”) has classified 1,4-dioxane as “likely to be carcinogenic to humans.” FDA studies showed that 1,4-dioxane can penetrate human skin.

PFAS/”Forever Chemicals”/ PTFE (Teflon)
PFAS (Per- and Polyfluoroalkyl Substances) are a group of synthetic chemicals widely used for their water- and grease-resistant properties. Commonly referred to as "forever chemicals" due to their persistence in the environment and the human body, PFAS are used in various products, including non-stick cookware, water-repellent fabrics, firefighting foam, and, increasingly, in personal care products like color cosmetics. In cosmetics, PFAS can improve the spreadability, long-lasting effects, and water resistance of products such as foundation, mascara, and lipstick.
Exposure to PFAS has been linked to a range of adverse health effects. These chemicals can accumulate in the body over time, potentially leading to liver damage, thyroid disruption, immune system effects, and an increased risk of certain cancers. Specifically in color cosmetics, concerns arise because these products are applied directly to the skin, eyes, and lips, allowing potential absorption into the bloodstream.
Phenoxyethanol (2-phenoxyethanol)
Phenoxyethanol (Additional Names: 2-phenoxyethanol)
A common preservative used in cosmetics, skincare, and personal care products. It is a member of the glycol ether family and is the product of the reaction of highly corrosive phenol with carcinogenic ethylene oxide. As a result, it may contain residue amounts of both. The American Society of Contact Dermatitis lists phenoxyethanol as one of its core allergens, even in concentrations as low as 1%.

Phthalates
A large group of chemicals, including dibutyl phthalate (DBP), diethylhexyl phthalate (DEHP), diethyl phthalate (DEP), dimethyl phthalate (DMP), and butyl benzyl phthalate (BBP). DBP, DEHP, and BBP are banned in the European Union from use in cosmetics due to their potential to disrupt the endocrine system and cause birth defects. DEP is commonly used as a fixative in synthetic fragrances. We do not use any synthetic fragrance in our products. The research on DEP is less conclusive but there is some evidence that it may interfere with the normal function of the endocrine system and cause birth defects in animals.

Propylene Glycol
A type of alcohol commonly used in skin care and cosmetics. It is a controversial ingredient associated with skin irritation. Numerous patch tests on humans have shown that it has a very low risk of causing a skin reaction even at concentrations as high as 20%. Since some people may still be sensitive to it, we decided not to use it in our products.

Quaternium-15
An antimicrobial preservative that slowly releases carcinogenic formaldehyde into a product over time (see Formaldehyde). People may develop a contact allergy to formaldehyde or to the ingredient itself. The American Society of Contact Dermatitis lists quaternium-15 and formaldehyde as allergens, even in concentrations as low as 2% and 1% respectively. Longer storage times and higher temperatures increase the amount of formaldehyde released from quaternium-15, which can lead to higher risks of health problems.

Resorcinol
Resorcinol is commonly used in permanent hair dye formulations and also in acne treatment skincare products. The European Scientific Committee on Consumer Safety has classified it as a strong sensitizer, meaning that it may cause an allergic reaction after repeated use. Both animal studies and case-reports involving humans have shown that resorcinol may disrupt thyroid hormone synthesis and produce goitrogenic effects.

Retinyl Palmitate / Retinol
(Additional Names: Retinoid, Retinoic Acid)
Are forms of vitamin A. While it might be a good ingredient to have in your night cream, it is not recommended to use during the day when exposed to the sun. Animal studies have shown that retinyl palmitate speeds up the photo-carcinogenic effects of the sun and the development of skin tumors and lesions.

Synthetic Colorants / FD&C / Lake Dyes
Lake dyes or FD&C colorants are synthetic, petroleum-derived ingredients that add color to cosmetics, skincare, other personal care products (like mouthwash), food (yes, food!), and various other products on the market.
There are currently nine certified color additives that have been “extensively studied” and “permanently approved” by the FDA for use in food:
FD&C Blue No. 1
- Confections, beverages, cereals, frozen dairy desserts, popsicles, frostings & icings
FD&C Blue No. 2
- Baked goods, cereals, snack foods, ice cream, confections, and yogurt
FD&C Green No. 3
- Cereal, ice cream, sherbet, drink mixers, and baked goods
Orange B
- Only approved for use in hot dog and sausage casings
Citrus Red No. 2
- Only approved for use to color orange peels
FD&C Red No. 3
- Confections, beverages, cereals, ice cream cones, frozen dairy desserts, popsicles, frostings & icings
FD&C Red No. 40
- Cereal, beverages, gelatins, puddings, dairy products, and confections
FD&C Yellow No. 5
- Confections, cereals, snack foods, beverages, condiments, baked goods, and yogurt
FD&C Yellow No. 6
- Cereals, snack foods, baked goods, gelatins, beverages, dessert powders, crackers, and sauces
Names for these synthetic colorants you may see on product labels are Blue 1, Blue 2, Yellow 5, etc. You will also see FD&C colorants can have the word “lake” added to the name, which means that these petroleum-derived, synthetic colorants have also been mixed with additional ingredients including but not limited to calcium and/or aluminum. For example: Red Lake 7
The FDA is correct that these synthetic colorants have been extensively researched, and several studies conclude that these colorants can, in fact, have a negative effect on behavior and overall health (mimics estrogen in the body=endocrine disruption and can even be carcinogenic). Not to mention that due to the nature of manufacturing, these colorants are also at a higher risk for heavy metal contamination. What’s even more alarming is that these colorants aren’t permitted for use in personal care or as food additives in some countries. Recently California led the nation with the first ban on six harmful food dyes in school food. Hopefully this is one of many initiatives we see in the near future.
Synthetic Flavors
Are chemical mixtures used in cosmetic products to create or mask a specific taste that may be ingested, such as lipstick. The FDA does not require the disclosure of individual ingredients used to create flavors. Many ingredients of flavors are associated with contact allergy.

Talc
(Additional Names: Hydrous Magnesium Silicate)
A naturally occurring mineral, mined from the earth. It may be contaminated with asbestos, a known human carcinogen. Animal studies performed by the National Toxicology Panel have shown some evidence that even asbestos-free talc can be carcinogenic. Perineal use of talc-based body powder has been classified as possibly carcinogenic to humans by the International Agency for Research on Cancer.

Triclosan
(Additional Names: 5-Chloro-2-(2,4-dichlorophenoxy)phenol)
An antibacterial agent in toothpaste and antibacterial hand and body washes, as well as a preservative in cosmetics and personal care products. Animal studies have shown that exposure to high doses of triclosan is associated with a decrease in the levels of thyroid hormones. Triclosan may bind to estrogen and/or androgen receptors and thus interfere with the normal function of the endocrine system. There is also evidence that exposure to triclosan contributes to making bacteria resistant to antibiotics. And triclosan imported from India and China may contain dioxins linked to cancer and endocrine-disruption.
