Zinc oxide is a mineral (inorganic) UV filter that provides broad-spectrum protection against UVA and UVB radiation by scattering and absorbing light. It also has mild astringent and soothing properties and is used in sunscreens, diaper creams, and barrier preparations.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin irritation | Very rare | Pure water is non-irritating; rare reports relate to extremely deionized water transiently disrupting skin barrier on prolonged exposure. |
| Transepidermal water loss/dryness | Rare | Excessive contact or frequent washing can contribute to barrier disruption and dryness, not a true allergic effect. |
| Allergic reaction | Very rare | Aquagenic urticaria is an exceptionally rare condition causing hives upon water contact. |
| White cast / cosmetic residue on skin | Common | Non-micronized particles can leave a visible white film, especially on darker skin tones. |
| Dryness or mild skin tightness | Uncommon | Due to its astringent nature, particularly in high concentrations. |
| Clogged pores / acne aggravation | Uncommon | More often attributed to occlusive base ingredients than to zinc oxide itself. |
| Contact irritation or stinging | Rare | Generally well tolerated; irritation often relates to other formulation components. |
| Allergic contact dermatitis | Very rare | True allergy to zinc oxide is uncommon; reactions usually involve other excipients or fragrances. |
| Comedogenicity / breakouts | Uncommon | Low comedogenic potential but may contribute to clogged pores in acne-prone skin. |
| Contact urticaria | Very rare | Isolated reports of hive-like reactions tied to benzoate moiety. |
| Mild skin irritation | Uncommon | Possible with high concentrations or sensitive/compromised skin. |
| Comedogenicity/pore congestion | Rare | Low comedogenic potential reported in most assessments. |
| Contact allergy/sensitization | Very rare | Allergic contact reactions are uncommon; the ingredient is generally regarded as low-risk. |
| Acneiform breakouts | Rare | As a fatty acid derivative, may theoretically contribute to comedogenicity in acne-prone skin, though data are limited. |

| Ingredient | What it does |
|---|---|
| \n\n\n\nPurified Water Solvent/base | Purified water is the most common solvent and vehicle in skincare formulations, used to dissolve ingredients and form the base of emulsions and aqueous products. It is biologically inert and serves no direct therapeutic role. |
| Zinc Oxide Key active UV filter / skin protectant | Zinc oxide is a mineral (inorganic) UV filter that provides broad-spectrum protection against UVA and UVB radiation by scattering and absorbing light. It also has mild astringent and soothing properties and is used in sunscreens, diaper creams, and barrier preparations. |
| C12-15 Alkyl Benzoate Emollient / texture enhancer | C12-15 Alkyl Benzoate is a lightweight ester emollient widely used in skincare and cosmetics to improve spreadability, provide a smooth non-greasy skin feel, and act as a solvent and mild antimicrobial booster. It is considered a base/formulation ingredient rather than a treatment active. |
| Isostearic Acid Emollient/emulsifier | Isostearic acid is a branched-chain fatty acid used in cosmetic formulations as an emollient, co-emulsifier, and dispersing agent that improves spreadability and texture. It is valued for its oxidative stability and liquid consistency compared to straight-chain stearic acid. |
| Polyhydroxystearic Acid Dispersant/emulsifier | Polyhydroxystearic acid is a fatty acid derivative used in cosmetic formulations primarily as a dispersing agent and emulsifier, helping to evenly distribute pigments (such as titanium dioxide and zinc oxide in sunscreens) and stabilize oil-based or water-in-oil systems. It improves texture, spreadability, and uniformity rather than providing a direct biological skin benefit. |
| Cyclopentasiloxane Emollient/silicone | Cyclopentasiloxane is a volatile cyclic silicone widely used in skincare and cosmetics to impart a smooth, silky feel and spreadability before evaporating, leaving no greasy residue. It also serves as a carrier and helps reduce tackiness in formulations. |
| PEG\/PPG-18\/18 Dimethicone Silicone-based emulsifier/surfactant | PEG/PPG-18/18 Dimethicone is a water-soluble silicone copolymer used primarily as an emulsifier and conditioning agent that helps stabilize formulations and impart a smooth, silky skin feel. It is a formulation/base ingredient rather than a therapeutic active. |
| Caprylyl Methicone Emollient / spreading agent | Caprylyl Methicone is a volatile silicone fluid used in cosmetic formulations to provide a light, non-greasy, smooth skin feel and to enhance the spreadability of products. It also acts as a solvent and carrier for other ingredients, particularly in sunscreens and color cosmetics. |
| PEG-12 Dimethicone\/PPG-20 Crosspolymer Silicone emulsifier/emollient | PEG-12 Dimethicone/PPG-20 Crosspolymer is a silicone-based crosspolymer used as an emulsifier, conditioning agent, and texture enhancer in cosmetic formulations. It helps stabilize emulsions and impart a smooth, silky feel to skincare and personal care products. |
| Silica Absorbent/texturizer | Silica is a mineral-derived ingredient (silicon dioxide) used in cosmetics to absorb oil and sebum, improve texture, and act as a bulking, anti-caking, or matting agent. It is generally inert and well tolerated on skin. |
| Glycerin Humectant | Glycerin is a widely used humectant that attracts and retains water in the skin, helping to hydrate the stratum corneum and support barrier function. It is considered safe and well-tolerated across most skin types and concentrations. |
| Dimethicone\/Vinyl Dimethicone Crosspolymer Silicone-based film former / texture enhancer | Dimethicone/Vinyl Dimethicone Crosspolymer is a crosslinked silicone polymer used in skincare and cosmetics as a thickener, emollient, and film-forming agent that imparts a smooth, silky feel and helps fill in fine lines and create a soft-focus matte finish. It is generally considered inert, non-comedogenic for most users, and well tolerated. |
| Cetyl PEG\/PPG-10\/1 Dimethicone Emulsifier/surfactant | Cetyl PEG/PPG-10/1 Dimethicone is a silicone-based nonionic emulsifier used to stabilize water-in-silicone and water-in-oil emulsions, commonly found in foundations, sunscreens, and color cosmetics. It helps disperse pigments and improve product spreadability and texture. |
| Sodium Chloride Thickener / viscosity adjuster | Sodium chloride (table salt) is commonly used in cosmetics as a thickening and viscosity-control agent, particularly in surfactant-based cleansers, and also acts as a mild abrasive in scrubs. It is generally well tolerated and considered a formulation ingredient rather than a treatment active. |
| Polymethylsilsesquioxane Texture enhancer / mattifying agent | Polymethylsilsesquioxane is a silicone-based spherical powder used in skincare and cosmetics to impart a smooth, soft-focus, mattifying feel and improve spreadability. It is a formulation/texture ingredient rather than a treatment active. |
| Caprylyl Glycol Humectant / skin-conditioning agent and preservative booster | Caprylyl glycol is a multifunctional emollient and humectant derived from caprylic acid that helps hydrate skin and enhance the efficacy of preservatives in formulations. It is widely used as a stabilizing and conditioning base ingredient rather than a therapeutic active. |
| Methylpropanediol Humectant/solvent | Methylpropanediol is a small glycol-type ingredient used in skincare as a humectant and solvent that helps hydrate skin and enhance the penetration of other actives. It also contributes to product texture and can support preservative efficacy. |
| Didecyldimonium Chloride Antimicrobial preservative/conditioning agent | Didecyldimonium Chloride is a quaternary ammonium compound (quat) used in cosmetics primarily as an antimicrobial preservative and antistatic conditioning agent. It is found in hair and skin formulations where it helps inhibit microbial growth and improves product feel. |
| Polyquaternium-80 Conditioning/film-forming agent | Polyquaternium-80 is a synthetic cationic (quaternized) polymer used in skincare and haircare as a conditioning and film-forming agent. It deposits a thin, smoothing film on skin or hair, improving sensory feel, hydration retention, and product texture. |
