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 Dishwasher Rinse Aid
Chemical Name
Why it’s harmful
Sodium Cumenesulfonate
Sodium Cumenesulfonate is a mild eye irritants that can be significantly absorbed upon ingestion but not after skin application. It has not shown skin sensitization in animal tests but have caused acute toxicity symptoms such as decreased activity, prostration, increased saliva production, diarrhea, and liver congestion. Furthermore, sodium cumenesulfonate has not demonstrated carcinogenic effects in dermal exposure studies.
Methylchloroisothiazolinone
5-chloro-2-methyl-4-isothiazolin-3-one (CMI) is a compound frequently used as a preservative in cosmetics, hygiene products, and other industrial applications such as hydraulic fracturing fluids. It can also be deployed as a pesticide in the U.S, pending regulatory approval. CMI, which is often used in combination with 2-methyl-4-isothiazolin-3-one (MI), can cause contact dermatitis in humans. Various animal studies have shown that a high exposure to a CMIT/MIT mixture can cause alterations in rats' liver function. The production and use of CMI in a range of products mean it can be release into the environment, with some susceptibility to degradation through photolysis in sunlight. Its mobility in soil is high but volatilization from soil or water surfaces is not expected to be significant. Occupational and general exposure to CMI can occur especially through inhalation and dermal contact with CMI-containing products.

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.

Trideceth-3
Trideceth-3 is a polyethylene glycol ether of Tridecyl Alcohol used in formulations for its emulsifying and surfactant properties. However, data from the European Union Ecolabel program indicates that this substance possesses high chronic toxicity and very high acute toxicity to aquatic life. Despite these environmental concerns, the Cosmetic Ingredient Review panel has determined Trideceth-3 to be safe when formulated to be non-irritating.
Diethylene Glycol Monoethyl Ether
Diethylene Glycol Monoethyl Ether, when administered orally or through the skin in doses exceeding 800-1000 mg/kg/day, can cause central nervous system depression and changes to the liver and kidneys in animals. However, it doesn't exhibit significant developmental toxicity at these levels. The chemical is not expected to have adverse effects unless workers are exposed to its heated liquid mists. It is an eye irritant and provokes harm to the central nervous system, liver, kidneys, red blood cells, and reproductive system in animal feeding studies. Despite these potential harms, it is poorly absorbed through the skin.
Glycolic Acid
Glycolic Acid is corrosive to the skin and eyes, with 70% technical solutions causing severe burns. It also irritates the respiratory tract and may lead to kidney failures. The chemical can cause burns when inhaled, leading to possible injuries to the upper respiratory tract and lungs. It is also harmful if ingested.
Isopropyl Alcohol
Isopropyl alcohol has been shown to cause narcosis in animals during acute studies, as cited by ACGIH. However, according to research by Zimmerman, it is not hepatotoxic in either experimental animal studies or in human exposures. It's known to be a skin, eye, and respiratory tract irritant, and if inhaled in high concentrations, it can cause CNS depression, as indicated by the ICSC.
