At Manos Soap, we've committed to a health and safety standard that goes well beyond what is legally required in the United States for chemical-free products specifically hand soap.

The Banned List is made up of questionable or harmful chemicals that we never use as ingredients in our products, plus additional chemicals screened by Manos Soap* and found to be of concern.

While all of our ingredients are sourced with a higher standard of safety and quality in mind from our vendors, it is well recognized and accepted by regulatory authorities around the world that incidental, trace levels of a chemical may inadvertently be introduced in a health and beauty product due to the complexities of the supply chain and manufacturing process.

*At Manos Soap, we work incredibly hard to minimize — but unfortunately, can’t eliminate — the potential that a product may contain trace levels of a chemical from The Banned List.

Cocamidopropyl Betaine

Cocamidopropyl betaine is a synthetic detergent and surfactant that is used to increase the foaming action of cleansing products and moderate the viscosity of liquids. As a synthetic surfactant, cocamidopropyl betaine is found in a number of personal hygiene products including hand soaps.

Butylatedhydroxy Anisole and Butylated Hydroxytoluene

Synthetic antioxidants used to extend shelf life. They are likely carcinogens and hormone disruptors and may cause liver damage. 


DEA is another chemical that you should be wary of. The chemical can cause liver and kidney cancer which is bad for the health.


Dioxane is a chemical that others think is good for the skin since it is derived from a synthetic coconut. However, this chemical is considered as a bad chemical since it can affect the kidneys, brain, and liver if not avoided.


Used as a preservative in cosmetics. A known carcinogen that is also linked to asthma, neurotoxicity, and developmental toxicity. Present where quaternium-15, DMDM hydantoin, imidazolidinyl urea, diazolidinyl urea, sodium hydroxymethylglycinate, 2-bromo-2-nitropropane-1,3 diol (Bronopol), and several other preservatives are listed. 

Methylisothiazolinone and Methylchloroisothiazolinone

Chemical preservatives that are among the most common irritants, sensitizers, and causes of contact skin allergies. 

Parabens (methyl-, isobutyl-, propyl- and others)

A class of preservatives commonly used to prevent the growth of bacteria and mold. Parabens are endocrine (or hormone) disruptors, which may alter important hormone mechanisms in our bodies. 


A group of chemicals used in hundreds of products to increase the flexibility and softness of plastics. They are known to be endocrine disruptors and have been linked to increased risk of breast cancer, early breast development in girls, and reproductive birth defects in males and females.

Polyethylene Glycol (PEG compounds)

PEGs are widely used in cosmetics as thickeners, solvents, softeners, and moisture-carriers. Depending on manufacturing processes, PEGs may be contaminated with measurable amounts of ethylene oxide and 1,4-dioxane, which are both carcinogens. 

Retinyl Palmitate and Retinol (Vitamin A)

A nutrient that may damage DNA and speed the growth of skin tumors when used topically. 

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. 

Synthetic Flavor or Fragrance

An engineered scent or flavoring agent that may contain any combination of 3,000-plus stock chemical ingredients, including hormone disruptors and allergens. Fragrance formulas are protected under federal law’s classification of trade secrets and therefore can remain undisclosed.

Triclosan and Triclocarban

Antimicrobial pesticides toxic to the aquatic environment; may also impact human reproductive systems.
