Ethylhexyl Methoxycinnamate (octinoxate) is a widely used organic UVB-absorbing sunscreen agent that protects skin from ultraviolet radiation. It is commonly incorporated into sunscreens and daily cosmetics with SPF claims.
Butyl Methoxydibenzoylmethane, also known as avobenzone, is a widely used organic sunscreen agent that absorbs UVA radiation. It is often combined with photostabilizers and other UV filters because it can degrade with sun exposure.
Benzophenone-3 (oxybenzone) is a broad-spectrum chemical UV filter that absorbs both UVB and short UVA radiation, commonly used in sunscreens and as a photostabilizer in cosmetic formulations. It also helps protect product integrity by preventing UV degradation of other ingredients.
Titanium dioxide is an inorganic mineral compound used primarily as a physical (mineral) sunscreen agent that reflects and scatters UV radiation, and also serves as a white pigment and opacifier in cosmetic formulations. It is broadly photostable and considered gentle, making it common in products for sensitive and pediatric skin.
Fructooligosaccharides are plant-derived prebiotic carbohydrates used in skincare to selectively nourish beneficial skin microbiota and support skin barrier health. They also provide mild humectant and soothing properties in topical formulations.
Tocopheryl acetate is a stable, esterified form of vitamin E used in skincare as an antioxidant and conditioning agent. It is converted to active tocopherol in the skin, helping protect against oxidative stress and supporting the skin barrier.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Irritation or sensitivity | Very rare | Purified water itself is essentially inert; rare reactions are attributable to contaminants or accompanying ingredients rather than water. |
| Transepidermal water loss aggravation in compromised skin | Rare | Evaporation of water from products may transiently increase dryness in very compromised skin barriers if occlusives are absent. |
| Contact irritation or mild stinging | Uncommon | Transient skin irritation, especially on sensitive or compromised skin. |
| Allergic contact dermatitis | Rare | Sensitization reported but relatively infrequent compared with other UV filters. |
| Photoallergic contact dermatitis | Rare | Reaction triggered by combined exposure to the ingredient and sunlight. |
| Potential endocrine/estrogenic activity | Very rare | Suggested by in vitro and animal studies; human relevance at cosmetic exposure levels remains uncertain. |
| Contact allergic reaction (allergic contact dermatitis) | Rare | Avobenzone is a recognized but uncommon cause of sunscreen allergy. |
| Photoallergic or photocontact dermatitis | Rare | Reactions triggered or worsened by sun exposure have been reported. |
| Skin irritation, redness, or stinging | Uncommon | Mild transient irritation may occur, particularly on sensitive or broken skin. |
| Eye irritation | Uncommon | Can cause stinging if the product migrates into the eyes. |
| Contact and photocontact allergic dermatitis | Uncommon | One of the more frequently reported photoallergens among UV filters, causing rash, redness, or itching, sometimes only upon sun exposure. |
| Skin irritation or stinging | Uncommon | Mild transient irritation, more likely on sensitive skin or near the eyes. |
| Systemic absorption | Common | Detectable in blood and urine after topical use; clinical significance is uncertain and under ongoing study. |
| Possible endocrine activity | Rare | Weak hormonal effects observed in laboratory and animal studies; relevance to humans at typical exposure remains unproven. |
