Ombrelle Ultra Light Advanced SPF 60

A hybrid organic-silicone UV filter that provides broad-spectrum protection. Stable and well-tolerated in cosmetic formulas.

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.

A hybrid organic-inorganic UV filter used in broad-spectrum sunscreens. Approved and graded safe at cosmetic concentrations.

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.

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.

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.

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.

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.

A synthetic ester used to thin out heavy formulas and help other ingredients absorb faster. It is considered safe as used by CIR, but it has a reputation among acne-prone users for feeling occlusive on skin, so people who clog easily may prefer to patch test or choose lighter alternatives.

A humectant that draws water into the skin. One of the best-studied, best-tolerated ingredients in personal care.

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.

A corn-derived solvent and humectant that has largely replaced propylene glycol in "clean" formulas; CIR reviewed the alkane diol group and found use concentrations up to about 40 percent in leave-on products like deodorant sticks with no meaningful irritation signal.

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

A pH buffer that neutralizes acidic ingredients to maintain a skin-compatible formulation pH. Decades of safety data and modern manufacturing practices support its use at cosmetic concentrations.

Caprylyl glycol is a plant-derived humectant that also has mild antimicrobial properties, so it is commonly paired with other preservatives to allow lower overall preservative levels. Available data do not point to meaningful irritation or sensitization concerns at typical use levels.

A cellulose derivative used to thicken and stabilize formulas. It dissolves fully in water and does not separate or settle over time. It is well tolerated and widely used in gels, lotions, and serums.

A crosslinked acrylic polymer that thickens and stabilizes formulations. Published assessments show it to be well tolerated at cosmetic use levels, with no evidence of penetration into viable skin layers or systemic absorption.

Pentylene glycol is a humectant and solvent that also offers mild antimicrobial support in formulas. It is generally well tolerated, with only rare reports of irritation, mostly in already sensitive or compromised skin.

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.

Used in tiny amounts to set a product to skin-friendly pH. No concern at those levels.
