Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (also known as Bemotrizinol or Tinosorb S) is a broad-spectrum organic UV filter that absorbs both UVA and UVB radiation. It is highly photostable and is commonly used in sunscreens and daytime skincare products to provide photoprotection.
Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (also known as Bisoctrizole or Tinosorb M) is an organic-particulate UV filter that provides broad-spectrum protection across both UVA and UVB ranges by absorbing and scattering UV radiation. It is photostable and commonly used in sunscreens, often paired with other filters.
Octinoxate (octyl methoxycinnamate) is an organic UVB-absorbing filter used in sunscreens and cosmetic products to help protect skin from ultraviolet-induced damage. It is one of the most widely used chemical UV filters in topical formulations.
Aggregated from the active ingredients in this product.
| Reported effect | How often | Notes |
|---|---|---|
| Skin dryness or barrier disruption with excessive contact | Uncommon | Frequent or prolonged exposure to water, especially hot or hard water, can disrupt the skin barrier and contribute to transepidermal water loss. |
| Irritation from impurities or hard water minerals | Rare | Reactions are attributed to contaminants, chlorine, or mineral content rather than water itself. |
| Mild transient stinging or irritation | Uncommon | More likely at high concentrations or on compromised/broken skin. |
| Tacky or sticky skin feel | Common | A cosmetic sensation rather than an adverse reaction, more noticeable at higher concentrations. |
| Contact dermatitis or allergic reaction | Rare | True allergy to glycerin is uncommon; patch-test positivity is infrequent. |
| Skin dehydration in very low humidity | Rare | In very dry environments humectants may draw water from deeper skin layers if not paired with an occlusive. |
| Allergic contact dermatitis | Rare | Documented in patch-test studies but considered a relatively weak sensitizer. |
| Redness or itching | Rare | Typically resolves after discontinuation. |
| Contact dermatitis / skin irritation | Rare | Occasional reports of mild irritation or redness in sensitive individuals. |
| Allergic contact dermatitis / sensitization | Very rare | Considered to have low allergenic potential; documented cases are uncommon. |
| Stinging or eye irritation | Rare | May occur if product migrates into the eyes, generally formulation-related. |
| Skin irritation or contact dermatitis | Rare | Occasional reports of mild irritation, generally considered well-tolerated. |
| Contact irritation or mild stinging | Uncommon | Transient redness or stinging, particularly on sensitive or compromised skin. |
| Photoallergic or photocontact dermatitis | Rare | Reaction triggered by combined exposure to the ingredient and sunlight. |
| Potential endocrine-disrupting (estrogenic) activity | Rare | Observed mainly in in vitro and animal studies; relevance to human topical use is debated. |

| Ingredient | What it does |
|---|---|
| Water Solvent/vehicle | Water is the most common base ingredient in cosmetic formulations, serving as a solvent that dissolves other ingredients and forms the bulk of emulsions and aqueous solutions. It is generally considered safe and non-irritating. |
| 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. |
| Butylene Glycol Humectant / solvent | Butylene glycol is a small diol commonly used in skincare as a humectant, solvent, and viscosity-reducing agent that helps dissolve other ingredients and improve skin feel. It is widely regarded as safe and non-sensitizing for the majority of users at cosmetic concentrations. |
| Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine Key active UV filter (sunscreen) | Bis-Ethylhexyloxyphenol Methoxyphenyl Triazine (also known as Bemotrizinol or Tinosorb S) is a broad-spectrum organic UV filter that absorbs both UVA and UVB radiation. It is highly photostable and is commonly used in sunscreens and daytime skincare products to provide photoprotection. |
| Methylene Bis-Benzotriazolyl Tetramethylbutylphenol Key active UV filter (broad-spectrum) | Methylene Bis-Benzotriazolyl Tetramethylbutylphenol (also known as Bisoctrizole or Tinosorb M) is an organic-particulate UV filter that provides broad-spectrum protection across both UVA and UVB ranges by absorbing and scattering UV radiation. It is photostable and commonly used in sunscreens, often paired with other filters. |
| Octinoxate Key active UV filter (chemical sunscreen) | Octinoxate (octyl methoxycinnamate) is an organic UVB-absorbing filter used in sunscreens and cosmetic products to help protect skin from ultraviolet-induced damage. It is one of the most widely used chemical UV filters in topical formulations. |
| Polymethyl Methacrylate Filler / texturizing agent | Polymethyl methacrylate (PMMA) is a synthetic acrylic polymer used in cosmetics as spherical microbeads or particles to improve texture, provide a smooth, soft-focus finish, and aid in oil absorption and even coverage. In dermal fillers it is used as non-biodegradable microspheres for soft tissue augmentation. |
| Nylon-12 Texture enhancer / mattifying agent | Nylon-12 is a synthetic polyamide powder used in cosmetics to improve texture, absorb oil and sebum, and provide a smooth, mattifying feel. It functions primarily as a bulking and slip-modifying agent in formulations such as powders, primers, and color cosmetics. |
| Dimethicone Emollient/occlusive (silicone) | Dimethicone is a silicone-based polymer used in skincare to soften skin, smooth texture, and form a breathable protective barrier that reduces transepidermal water loss. It is widely used as a base/formulation ingredient rather than a therapeutic active. |
| 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. |
| 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. |
| Methylisothiazolinone Preservative | Methylisothiazolinone (MI) is a synthetic isothiazolinone preservative used in cosmetics and personal care products to prevent microbial growth. It is effective at low concentrations but is recognized as a significant contact allergen. |
| Disodium EDTA Chelating agent | Disodium EDTA is a chelating agent used in cosmetics to bind metal ions, improving product stability, preventing rancidity, and enhancing the efficacy of preservatives. It is a formulation/base ingredient rather than a treatment active. |
