Why this score

Concern47 / 55
  • No ingredients carry meaningful, evidence-backed concern.

How much genuine, cited concern the ingredients carry, weighted by how much of each is likely present and whether the product stays on or rinses off.

Transparency20 / 20
  • No hidden fragrance blend.

Whether the full ingredient list, and any fragrance, are actually disclosed.

Formulation restraint17 / 25
  • 1 known irritant or fragrance-allergen ingredient: Octocrylene.

Needless irritant or allergen load for the product type. A clean, purposeful formula scores well without any "free-from" theater.

What’s inside

WaterGenerally safe

The base most products are built on. It carries the other ingredients and has no safety concern.

Full ingredient details →
OctocryleneWatch if sensitive

An organic UV-B filter that also stabilizes other sunscreen actives like avobenzone. The EU SCCS reviewed it and concluded it is safe at current use levels, though rare contact allergy has been reported and older, degraded product may form small amounts of benzophenone.

HomosalateLimited concern

A UV-B filter used in sunscreens. After reassessing hormone-activity data, the EU lowered its permitted maximum concentration as a precaution, but concluded the ingredient remains safe for use at the new lower limit.

Full ingredient details →
Styrene/Acrylates CopolymerGenerally safe

A synthetic polymer used to form a water-resistant film and keep chemical UV filters evenly suspended in sunscreen lotions. It is not absorbed through skin and CIR has not flagged it as a safety concern in cosmetic use.

Full ingredient details →
OctisalateGenerally safe

A mild UVB chemical filter usually used to help dissolve and stabilize other sunscreen actives. It has a long OTC history at US-approved levels with a low rate of reported irritation.

Full ingredient details →
AvobenzoneGenerally safe

A widely used organic UV-A filter in sunscreens. It can lose effectiveness in sunlight unless paired with photostabilizers, but safety reviews have not found it to pose a meaningful health hazard at approved use levels.

Full ingredient details →
SilicaGenerally safe

A mineral thickener and anti-caking agent widely used in sunscreens and cosmetics to control texture and prevent ingredient separation. CIR has reviewed silica in cosmetic use and found no basis for concern at the levels used topically.

Full ingredient details →
Glyceryl StearateGenerally safe

A common emulsifier and texture-softener made from glycerin and stearic acid. CIR review of this class found no evidence of reproductive, carcinogenic, sensitizing, or phototoxic effects in the studies examined.

Below the 1% line

EthylhexylglycerinGenerally safe

A glycerin derivative used as a skin conditioner and preservative booster, often paired with phenoxyethanol to allow lower total preservative levels. It has a low irritation and sensitization profile in safety reviews.

Full ingredient details →
DimethiconeCommonly feared, low concern

A silicone that gives a smooth, soft feel and helps hold water in the skin. Inert and well studied.

Full ingredient details →
Xanthan GumGenerally safe

Xanthan gum is a microbial-fermentation-derived polysaccharide used to thicken and stabilize textures, similarly common in food. Cosmetic panel review of this and related microbial gums found them safe as used, with no meaningful irritation signal at typical concentrations.

Full ingredient details →
Tocopheryl AcetateCommonly feared, low concern

A more stable, esterified form of vitamin E used as an antioxidant and skin-conditioning ingredient. It is a different substance from the vitamin E acetate implicated in vaping-related lung injury, which involved inhaling the oil, not applying it topically to skin.

Full ingredient details →
Disodium EDTACommonly feared, low concern

A chelating agent that binds trace metal ions to keep formulas stable and preservatives working properly. It is not a functional skincare "active" and only a very small amount is used, with minimal skin penetration expected.

Full ingredient details →
BHTCommonly feared, low concern

A small-dose synthetic antioxidant that prevents oils and fragrance in a formula from oxidizing. Not shown to pose a toxicological risk at the levels used in cosmetics.

Full ingredient details →
PhenoxyethanolCommonly feared, low concern

A widely used preservative, safe at the legal limit of 1% or less. Often the "paraben-free" replacement.

Full ingredient details →
Benzyl BenzoateWatch if sensitive

A fragrance fixative and solvent found naturally in balsams and used to help scents last longer. It is one of the 26 EU-designated fragrance allergens, with documented but uncommon contact sensitization.
