Our Product Rating System
First, Camille (co-creator of Welpr) hand picks cleaner product options from a variety of sources.
Next, we collect information about each product's safety, consumer satisfaction, and eco-ethical standing.
Finally, we run all this information through an algorithm that calculates the Welpr Rating.
Welpr Rating:
5.0/5
Part 1: Product safety
We evaluate safety information from 3rd party organizations (e.g. EWG, Made Safe, etc.). Instead of relying solely on any one of these companies for safety information, we assess all of them.
Part 2: Consumer satisfaction
We scour the web for consumer ratings and reviews to verify products are not only cleaner options, but also effective. Products can either be Above Average, Average, or Below average for their respective category (e.g. cleaning products).
Part 3: Ethics & Environment
When you buy a product, you’re supporting that company with your dollars. We believe it’s important to support ethical companies, so we pool together certifications that verify a company's ethics and environmental impact.
Common Harmful Chemicals in Bar Soap
Chemical Name
Why it’s harmful
Formaldehyde
Formaldehyde is a colorless, flammable gas with a pungent smell that's naturally produced in small quantities in human bodies and is also known as methanal amongst other names. It's used in the production of various items such as fertilizers, paper, plywood, and urea-formaldehyde resins as well as in some foods and household products like antiseptics, medicines, and cosmetics. Exposure to formaldehyde, which can occur through breathing contaminated indoor air, tobacco smoke, or ambient urban air can lead to respiratory symptoms, irritation of the eyes, nose and throat and has been linked to lung and nasopharyngeal cancer as well as leukemia. The EPA considers formaldehyde a probable human carcinogen (Group B1) and inhaling it can cause bronchospasm and pulmonary edema. Commercially, it's sold as formalin in solutions of 37%, 44%, or 50% and long-term exposure can cause first-degree burns, skin sensitization, squamous cell nasal cancer, and chronic pulmonary obstruction.

Phthalate
Phthalates, linked to endocrine disruption, reproductive toxicity, and cancer, are banned in the European Union but remain prevalent in U.S. cosmetics. They are widely used in personal care products, such as nail polish, fragrances, and eyelash glue and other products. A significant loophole allows phthalates to be added to fragrances without disclosure. Health concerns include endocrine disruption, developmental and reproductive toxicity, and potential carcinogenicity.

1,4-Dioxane
1,4-Dioxane is a clear, water-soluble liquid that is primarily used as a solvent in chemical manufacturing and laboratory reagents. Other uses leverage its solvent properties, including cosmetics, detergents, and shampoos. However, manufacturers generally reduce 1,4-Dioxane to low levels in these products due to its potential health risks. Acute exposure can result in symptoms such as vertigo, drowsiness, and irritation of the eyes, nose, throat, and skin. Chronic exposure may lead to liver and kidney damage, and the substance is classified as a probable human carcinogen by the EPA. Notably, severe kidney and liver damage, CNS effects, and even death have been recorded after heavy or prolonged exposure.

Triclosan
Triclosan is a synthetic pesticide with antibacterial properties commonly added to detergents, soaps, and various personal care products such as deodorants and toothpastes. Although it lacks the ability to combat viruses causing colds and flus, it's used in products like body washes, disinfectants, and some toothpastes to resist bacterial growth. In 2016, the FDA limited its use in antibacterial soaps, but the compound is still permitted in other products. The European Union prohibited its presence in food-contact items in 2010. Exposure to triclosan has been associated with hormone disruption, increased breast cancer risk, liver damage, and the development of resistant super-germs.

Methylisothiazolinone
Methylisothiazolinone can reportedly cause allergic contact dermatitis in workers who interact with products containing it. This substance is recognized as a contact allergen for consumers using cosmetics that include it. It can cause skin burns and sensitization, and inhaling it may lead to corrosive injuries in the upper respiratory tract and lungs. Ingesting this substance is harmful, and inhalation is toxic. This preservative is linked to the category of isothiazolinones.

Sodium Lauryl Sulfate
Sodium Lauryl Sulfate is recognised as a skin, eye, and respiratory tract irritant according to ICSC. It may cause allergic reactions and eye irritation as stated by the HSDB. Exposure may even result in eye burns, as per CAMEO. Depending on its form - which may range from a solid (90-98% purity), to a paste (30-41%), or an aqueous solution (28-50%) - it can significantly irritate skin and eyes, with adverse effects escalating with increased concentration. Despite these hazards, it is not a skin sensitizer according to CHEMINFO, while eChemPortal: ERMA and MSDSonline endorse its classification as an irritant.
