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 Teeth Whitening Products
Chemical Name
Why it’s harmful
Ammonium Hydroxide
Ammonium hydroxide is a corrosive substance that can cause injury to the skin, eyes, and respiratory tract. High concentrations, either through inhalation or prolonged exposure, can lead to significant respiratory issues, including inflammation, pneumonia, and pulmonary edema. It is used in various industries such as fertilizers, dyes, explosives, plastics, and cleansing agents, among others. Due to its intense pungency and potential to cause extreme irritation and even life-threatening conditions, precautions such as wearing protective clothing and immediate cleansing of affected areas are recommended. It should be stored away from combustibles and heavy metals, in well-ventilated areas and in specified containers. Disposal guidelines also need to be referred from environmental regulatory agencies due to the hazardous nature of the substance.

Diethanolamine
Diethanolamine is a chemical found in various consumer products like shampoos, cosmetics, and pharmaceuticals. Acute exposure in humans can result in irritation of the nose, throat, and skin. However, no detailed data is available on its chronic, reproductive, developmental or carcinogenic effects on humans. Studies on animals reveal that acute oral exposure can influence the liver, blood, kidney, and central nervous system, while dermal exposure has been connected with an increased incidence of liver and kidney tumors in mice. Production of first-degree burns, skin irritation, occupational asthma, kidney, and liver injury risk, and potential skin sensitization are some other adverse effects associated with diethanolamine.

Sodium Hydroxide
Sodium hydroxide, also known as caustic soda or lye, is an odorless white crystalline solid that absorbs moisture from the air. It generates significant heat when dissolved in water or neutralized with acid which may ignite combustible materials. It is highly corrosive and is typically used as a solid or in a 50% solution. Sodium hydroxide is used to manufacture a variety of products including soaps, rayon, paper, explosives, dyestuffs, and petroleum products. Exposure to this substance may cause severe burns, necrosis, and pulmonary edema, depending on the concentration and exposure method.
Polyethylene Glycol
Ingestion or dermal absorption of the chemical at more than 800-1000 mg/kg/day can lead to central nervous system depression and liver and kidney changes in animals, despite there being no significant developmental toxicity. The chemical acts as an eye irritant; however, it is poorly absorbed through the skin. Unanticipated side effects are unlikely unless there is exposure to mists of heated liquid. Notably, animal feeding studies have shown that the chemical could damage the CNS, liver, kidneys, red blood cells, and the reproductive system.
