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 Stretch Mark Cream
Chemical Name
Why it’s harmful
Sodium Laureth Sulfate
Sodium laureth sulfate, derived from ethoxylated lauryl alcohol, is a surfactant used in sudsy products like toothpaste, detergents, and shampoos. While it acts as a cleansing and emulsifying agent, it can sometimes contain toxic impurities such as 1,4-dioxane. This chemical has raised health concerns due to its potential to cause skin, lung, and eye irritation, organ toxicity, and, primarily because of contamination by 1,4 dioxane, cancer.

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.
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.
Sources:

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.
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.
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.

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.
DMDM hydantoin
DMDM hydantoin is a substance used in cosmetics that has the potential to cause allergic contact dermatitis, although rinse-off products generally have a low risk. According to various reports, skin sensitization patch testing has yielded positive results.
