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.
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.
3-O-Ethyl Ascorbic Acid is a stable, water-soluble ethylated derivative of vitamin C that converts to ascorbic acid in the skin, providing antioxidant protection and supporting collagen synthesis and pigmentation control. It is valued for greater stability than pure L-ascorbic acid while delivering similar brightening and anti-aging benefits.
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 allergic dermatitis | Uncommon | Benzophenones are recognized contact allergens, particularly in sensitized individuals. |
| Photoallergic or photocontact reactions | Uncommon | Can trigger skin reactions upon combined exposure to the ingredient and sunlight. |
| Skin irritation (redness, stinging) | Rare | Mild localized irritation reported in some users. |
| Endocrine-disruption concerns | Rare | Some benzophenone derivatives show estrogenic activity in laboratory studies; relevance to topical human use is debated. |
| Systemic absorption | Very rare | Trace absorption has been detected in some studies, though clinical significance remains uncertain. |

| Ingredient | What it does |
|---|---|
| Aqua Solvent / vehicle | Aqua (water) is the most common base ingredient in skincare formulations, serving as a solvent that dissolves water-soluble components and forms the medium for emulsions. It has no direct treatment activity and primarily contributes to texture, spreadability, and product delivery. |
| Ethylhexyl Methoxycinnamate Key active UV filter (UVB sunscreen) | 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 Key active UV filter (UVA sunscreen) | 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. |
| Diphenylmethanone UV filter / photostabilizer | Diphenylmethanone (benzophenone) is an aromatic ketone used in cosmetics primarily to absorb ultraviolet light, protecting both the product formulation and skin from UV-induced degradation. It is commonly found in sunscreens and as a stabilizer in fragranced and packaged products. |
| Phospholipids Emollient / skin-conditioning agent and liposome-forming emulsifier | Phospholipids are amphiphilic lipids (commonly derived from soy or egg lecithin) used in skincare to form liposomes, stabilize emulsions, and reinforce the skin barrier. They also enhance penetration and delivery of other actives. |
| 1,3-Butylene Glycol Humectant / solvent | 1,3-Butylene glycol is a small diol used in skincare as a humectant, solvent, and viscosity modifier that helps retain moisture and improve product texture. It also has mild antimicrobial properties that can aid preservation. |
| 1,2-Propanediol Humectant / solvent | 1,2-Propanediol (propylene glycol) is a small diol used in skincare as a humectant, solvent, and penetration enhancer, helping retain moisture and dissolve other ingredients. It is widely used as a formulation base across cosmetic and topical products. |
| Titanium Dioxide Key active UV filter / mineral sunscreen | 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. |
| Methyl Methacrylate Crosspolymer Texture enhancer / mattifying agent | Methyl Methacrylate Crosspolymer is a synthetic polymer used in cosmetics as a film-former and oil-absorbing powder that imparts a smooth, soft-focus, matte feel to formulations. It functions primarily as a sensory and texturizing base ingredient rather than a skin-treatment active. |
| Acrylates/C10-30 Alkyl Acrylate Crosspolymer Rheology modifier / emulsion stabilizer | Acrylates/C10-30 Alkyl Acrylate Crosspolymer is a synthetic crosslinked acrylic polymer used to thicken, gel, and stabilize emulsions in skincare and cosmetic formulations. It helps suspend ingredients and provides a smooth, consistent texture without acting as a treatment active. |
| Ethylhexyl Glycerin Preservative booster / skin-conditioning agent | Ethylhexyl glycerin is a multifunctional ingredient used primarily as a preservative-enhancer and humectant in cosmetic formulations. It also acts as a deodorizing agent by inhibiting odor-causing bacteria and improves the skin-feel of products. |
| Phenoxyethanol Preservative | Phenoxyethanol is a widely used broad-spectrum preservative that protects cosmetic and skincare formulations from bacterial and fungal contamination. It is typically used at concentrations up to 1% and serves as a formulation/base ingredient rather than an active treatment. |
| Sodium Gluconate Chelating agent / skin-conditioning | Sodium gluconate is the sodium salt of gluconic acid used in skincare primarily as a chelating agent to bind metal ions and stabilize formulations, with secondary humectant and skin-conditioning properties. It is generally considered a base/formulation ingredient rather than an active treatment. |
| 3-O-Ethyl Ascorbic Acid Key active Antioxidant / brightening vitamin C derivative | 3-O-Ethyl Ascorbic Acid is a stable, water-soluble ethylated derivative of vitamin C that converts to ascorbic acid in the skin, providing antioxidant protection and supporting collagen synthesis and pigmentation control. It is valued for greater stability than pure L-ascorbic acid while delivering similar brightening and anti-aging benefits. |
| Sodium Hydroxide pH adjuster | Sodium hydroxide (lye) is a strong alkaline compound used in small amounts to adjust and stabilize the pH of cosmetic formulations. At regulated low concentrations in finished products it is considered safe, though it is corrosive in concentrated form. |
