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 Korean Skin Care Products
Chemical Name
Why it’s harmful
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.
Oxybenzone
2-Hydroxy-4-methoxybenzophenone (Benzophenone-3; BP-3) is a compound used as a UV absorber and stabilizer in plastics, paints, and sunscreens. Human studies have found photosensitivity to it, while non-human animal studies have found that high concentrations contribute to changes in liver weight and disruptions to reproductive parameters in mice and rats. It is identified as an endocrine-disrupting chemical and can affect the behavior of certain fish species. Despite this, it did not induce gene mutations in tests with the bacterium Salmonella typhimurium.
Butylated Hydroxytoluene
BHT, a toluene-based ingredient, serves as a preservative in food and personal care products. Safety assessments have noted toxic effects in lung tissue when BHT was applied to rats' skin but considered the low concentrations in cosmetics safe. The American Conference of Governmental Industrial Hygienists (ACGIH) suggests moderate evidence of BHT being a respiratory irritant in humans.
Toluene
Toluene is a clear, colorless liquid that naturally occurs in crude oil and the tolu tree. It's prominent in the production of gasoline, coke from coal, and various consumer products like paints, adhesives, and nail polish. Toluene is even added to gasoline, used to create benzene, and acts as a solvent. However, exposure to toluene, especially from inhalation, can have serious health effects. It primarily targets the central nervous system, inducing symptoms like fatigue, nausea, headaches, and in chronic cases, can cause severe dysfunction. Exposure has also been linked to developmental effects in children, but there isn't enough evidence to conclude its carcinogenic potential. Abuse of toluene can cause permanent brain damage, liver injury, and even potential birth defects or increased risk of spontaneous abortions in pregnant women. Despite these risks, cognitive deficits from toluene exposure below a threshold limit value (TLV) of 50 ppm remain extremely low.
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.

Phenoxyethanol
2-Phenoxyethanol is a hazardous substance toxic by all routes of exposure, and is used widely in products like cosmetics, soaps, and inks, among others. The effects of exposure to this faintly aromatic, colorless, oily liquid can include eye irritation, headaches, tremors, and CNS depression. It's crucial to rinse exposed eyes with tepid water for at least 15 minutes and to wash exposed skin thoroughly with soap and water in case of contact. The substance requires preheating before ignition can occur, and if involved in a fire, gentle water spray can extinguish the fire by inducing frothing.
Retinol
Oral administration of high doses in adults causes ciricrhosis, hemorrhage, anorexia, jaundice, and dermatitis. The use of this substance is contraindicated in pregnancy at doses larger than the FDA recommend daily allowance. Ingesting 25,000 IU/d over a period of 2-3 weeks may result in toxicity, symptoms of which include liver injury and increased intracranial pressure, leading to blurred vision, headaches, and changes to mental status. The substance is also found to be an irritant and harmful if ingested, with teratogenic effects observed in experimental animals.
Benzophenone
Benzophenone (BZP) is a photoinitiator, fragrance enhancer, and ultraviolet stabilizer, used in a variety of industrial applications. Despite not being registered as a pesticide in the U.S., it's involved in the production of insecticides and agricultural chemicals. Its toxic effects on humans are scarcely documented, but it presents little hormonal activity on cell lines. Animal studies show it possesses no estrogenic activity, but it can transform into derivatives with such activity under UV irradiation. It did not show reproductive toxicity or carcinogenicity in rats and mice, respectively, even at high doses. It can be bioactivated through specific enzymes. For aquatic life, fathead minnow larvae were more sensitive to BZP, ranking it in the middle of the toxicity order of six benzene derivatives.

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.
