EOS
EOS (Evolution of Smooth) launched in 2009 and quickly became one of the best-selling lip balm brands in the United States, largely due to its distinctive spherical packaging and social media-friendly branding. The brand markets itself as using natural and organic ingredients, and some of its products are USDA Organic certified. However, EOS faced a class-action lawsuit in 2016 from consumers who claimed the lip balm caused severe blistering, cracking, and rashes, raising questions about ingredient safety even in products marketed as natural. While EOS reformulated some products in response, the incident highlighted how 'natural' labeling does not always guarantee safety for all users.

Flagged Ingredients in EOS Products
We found 7 different ingredients of concern across EOS's product line. Each one links to a full safety analysis with details on health risks, regulatory status, and which other brands use the same ingredient.
Homosalate
A chemical UV filter that absorbs UVB radiation. Used in sunscreens and SPF cosmetics, homosalate is an endocrine disruptor that breaks down into more toxic byproducts under UV exposure.
Polyethylene Glycol (PEG Compounds)
A family of petroleum-derived compounds used as emulsifiers, thickeners, solvents, and penetration enhancers. PEGs themselves are relatively low-toxicity, but they are frequently contaminated with ethylene oxide (a known carcinogen) and 1,4-dioxane.
Avobenzone
One of the few chemical UV filters that provides good UVA protection. However, it is photounstable, breaking down rapidly under UV light and losing effectiveness within 30 minutes unless stabilized by other chemicals.
Octisalate
A chemical UV filter that absorbs UVB radiation and is commonly used as a secondary sunscreen agent to boost SPF values. Octisalate also acts as a solvent for other UV filters like avobenzone.
BHT (Butylated Hydroxytoluene)
A synthetic antioxidant closely related to BHA, used to prevent oxidation in cosmetics and food. Less studied than BHA but shares some endocrine disruption concerns.
Dimethicone
A silicone-based polymer widely used in cosmetics and skincare for its smoothing, water-repellent properties. Not toxic in itself, but creates a synthetic barrier that can trap impurities, clog pores, and is not biodegradable.
Phenoxyethanol
A glycol ether used as a preservative in cosmetics, often marketed as a 'safer' alternative to parabens. At regulated concentrations (up to 1%), it is generally well tolerated, but higher concentrations can cause irritation and are toxic to infants.
