Why this score

Concern27 / 55
  • Alpha-Isomethyl Ionone: watch if sensitive
  • Citronellol: watch if sensitive
  • Fragrance: watch if sensitive

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.

Transparency12 / 20
  • Uses an undisclosed "fragrance/parfum" blend, so its scent allergens are hidden.

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

Formulation restraint0 / 25
  • 8 known irritant or fragrance-allergen ingredients: Alcohol Denat., Alpha-Isomethyl Ionone, Benzyl Alcohol, Benzyl Salicylate, Citronellol, Fragrance, Hexyl Cinnamal, Linalool.

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

What’s inside

Alcohol Denat.Watch if sensitive

A fast-evaporating solvent used to carry actives and give toners a light, "clean" feel; at the concentrations used in classic astringents it can be genuinely drying or irritating with repeated use, especially on dry or compromised skin, though it is not inherently toxic and is a normal, well-studied cosmetic ingredient.

Full ingredient details →
Alpha-Isomethyl IononeWatch if sensitive

Alpha-isomethyl ionone is a violet-scented fragrance material and one of the EU-listed allergens requiring label disclosure. Documented sensitization is more common with this ingredient than with many other listed fragrance allergens.

Full ingredient details →
Aluminum HydroxideGenerally safe

An inert mineral powder used as a filler and white base for color cosmetics. It is not the same as the antiperspirant aluminum compounds that trigger health concerns. Well tolerated and FDA-approved for cosmetic use.

Full ingredient details →
Benzyl AlcoholWatch if sensitive

A common preservative and fragrance/solvent ingredient found naturally in many essential oils. It is well tolerated by most people at the levels used in cosmetics, but it is one of the 26 EU-designated fragrance allergens and can trigger reactions in people with an existing sensitivity.

Full ingredient details →
Benzyl SalicylateWatch if sensitive

Benzyl salicylate is a fragrance fixative that also absorbs some UV light. It is on the EU allergen disclosure list, but the evidence suggests it sensitizes fewer people than most other listed fragrance allergens.

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 →
Bis-PEG/PPG-14/14 DimethiconeGenerally safe

Bis-PEG/PPG-14/14 Dimethicone is a silicone backbone capped with polyethylene glycol and polypropylene glycol chains, added to formulas to help water and silicone oils blend into one stable product. It works as an emulsifier and skin-feel conditioner rather than an active ingredient. CIR has reviewed the broader group of PEG/PPG-modified (alkoxylated) polysiloxanes this ingredient belongs to and did not flag a specific safety concern, though this exact ingredient has not been the subject of its own standalone report.

Full ingredient details →
Butylene GlycolCommonly feared, low concern

A lightweight humectant and solvent similar in role to propylene glycol, used to carry actives and give lotions a lighter feel. CIR has reviewed it and considers it safe as used in cosmetics.

Full ingredient details →
CitronellolWatch if sensitive

A rose-scented fragrance ingredient found naturally in geranium and rose oil. It is one of the 26 fragrance allergens the EU requires to be labeled by name because a minority of people develop skin sensitization to it, though most users tolerate it without issue.

Full ingredient details →
Diisopropyl SebacateGenerally safe

A lightweight ester emollient rated safe at concentrations up to 10 percent by the CIR Expert Panel. It has been assessed as low irritation, non-comedogenic, and shows no evidence of endocrine disruption in published literature.

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 →
Sodium Stearoyl GlutamateGenerally safe

An amino acid derived emulsifier made from stearic acid and glutamic acid that is increasingly used in natural and clean formulations. It is mild, biodegradable, and presents no known safety concerns for cosmetic use.

Full ingredient details →
Disteardimonium HectoriteWatch if sensitive

A quaternized clay mineral used to thicken and suspend products. CIR found it safe as used, though the mineral base means trace amounts of inhalable silica particles exist if the powder form is aerosolized. It is well tolerated in leave-on and rinse-off cosmetics when formulated properly.

Full ingredient details →
FragranceWatch if sensitive

An undisclosed scent blend that can contain dozens of components. The single most common cause of cosmetic contact allergy, and the blend is not itemized, so you cannot see what is in it.

Full ingredient details →
HDI/Trimethylol Hexyllactone CrosspolymerGenerally safe

A synthetic polymer used to create film-forming serums and gels. It is stable, non-irritating, and widely used in cosmetic formulations to improve texture and adherence without toxicological concerns.

Full ingredient details →
Hexyl CinnamalWatch if sensitive

A jasmine-like fragrance compound frequently used in soaps and lotions. It is one of the 26 EU-designated fragrance allergens, though studies suggest its sensitization potency is comparatively low relative to other listed allergens.

Full ingredient details →
Hydrogen DimethiconeGenerally safe

A silicone-based resin that provides a smooth, velvety finish in primers and foundations. Silicones of this type are non-comedogenic and well tolerated by most skin types when used in cosmetic formulas.

Full ingredient details →
Iron OxidesGenerally safe

Mineral pigments used to add color to cosmetics. Iron oxides are FDA-approved colorants with a well-established safety record in cosmetic formulations.

Full ingredient details →
IsododecaneGenerally safe

A lightweight hydrocarbon that gives formulas a smooth, silky feel. Used in color cosmetics and sunscreens. Well tolerated and inert.

Full ingredient details →
LinaloolWatch if sensitive

A floral fragrance component and one of the EU-labelled fragrance allergens. Usually fine, worth watching if you react to scented products.

Full ingredient details →
Magnesium SulfateGenerally safe

A mineral salt used in cosmetics as a humectant and antioxidant. It is the same compound used in food and personal care products, and is well tolerated in both rinse-off and leave-on formulations.

Full ingredient details →
Nylon-12Generally safe

A synthetic polymer used to impart silky texture and film-forming properties in skincare. Nylon particles remain on the surface and do not penetrate or absorb systemically, with a long history of safe use in cosmetics.

Full ingredient details →
OctinoxateWatch if sensitive

A widely used UVB chemical filter with a long safety record at US-approved concentrations. Some lab and animal studies have raised questions about hormone activity and coral reef impact, which is why a few jurisdictions cap or restrict it, but human-relevant risk at labeled use levels is considered low by regulators.

Full ingredient details →
PEG-10 DimethiconeGenerally safe

A silicone emulsifier combining polyethylene glycol and dimethicone to help blend water and oil phases in serums and primers. Limited but consistent data support its safety in cosmetic formulations.

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 →
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 →
Silica SilylateGenerally safe

Silica silylate is silica surface-treated with trimethylsilyl groups so it feels silkier and disperses better into oil-based formulas; it works as an anti-caking and viscosity-control agent in pressed powders, foundations, and other makeup. CIR reviewed it in the same assessment as silica dimethyl silylate and trimethylsiloxysilicate and concluded it's safe as used, with the same caveat that the finished product should be formulated not to irritate the eyes or respiratory tract.

Full ingredient details →
Synthetic FluorphlogopiteCommonly feared, low concern

Synthetic fluorphlogopite is a lab-grown mica look-alike made of layered magnesium aluminum silicate sheets with some fluorine substitution, used as a shimmer and pearlescent base in powders, eyeshadow, and skincare. CIR's expert panel reviewed irritation, sensitization, and genotoxicity data and concluded it's safe as used at reported concentrations up to 67%.

Full ingredient details →
Titanium DioxideCommonly feared, low concern

A mineral UV filter and white pigment used in sunscreens and makeup. It sits on the skin surface rather than being absorbed, and major regulators consider it safe for topical cosmetic use.

Full ingredient details →
Vitamin EGenerally safe

An antioxidant that helps protect a formula and condition skin. Well tolerated.

Full ingredient details →
TrimethylsiloxysilicateGenerally safe

Trimethylsiloxysilicate is a silicone resin built from trimethylsiloxy and silicate units, used in makeup and skin and hair products to form a light, flexible film that adds body, wear, and a soft-focus finish. CIR's expert panel reviewed clinical and animal data on this and related silylates and concluded the ingredient is safe as used, provided the finished product is formulated so it isn't irritating to the eyes or respiratory tract when it's inhaled as a fine powder or aerosol.

Full ingredient details →
WaterGenerally safe

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

Full ingredient details →

Note: this product hides its scent as an undisclosed “fragrance/parfum” blend, so its specific allergens are not on the label.
