Performance Scores

SPF Level

Excellent

Label claims SPF 50, which is corroborated by the presence of dedicated UVB filters Homosalate and Octinoxate in the active ingredients.

Broad Spectrum

Fair

Diethylamino Hydroxybenzoyl Hexyl Benzoate (Uvinul A Plus) provides strong continuous coverage across the UVA spectrum (peak 354 nm), satisfying the criteria for a well-stabilised single UVA filter.

Sweat Resistance

Poor

The inactive ingredient list is composed entirely of volatile solvents, humectants, and antioxidants, lacking any recognized film-forming or water-proofing agents.

Photo Stability

Poor

Cosmetic science literature confirms Ethylhexyl Methoxycinnamate (Octinoxate) degrades and loses efficacy under sustained UV exposure unless co-formulated with complementary photostabilizers, which are absent here.

Visible Light

Poor

Absence of iron oxide color indices (e.g., CI 77491, CI 77492, CI 77499) or pigmentary-grade non-white minerals in the ingredient list.

Irritation Risk

High Risk

Dermatological literature consistently shows that high concentrations of short-chain volatile alcohols denature stratum corneum lipids, compromising barrier function.

Pore Clogging

Low Risk

Dermatological reference scales rate the primary vehicle (ethyl alcohol), glycols, and the included chemical UV filters as 0/5 for comedogenicity.

White Cast

Low Risk

The formulation contains zero titanium dioxide or zinc oxide, completely eliminating the physical mechanism required for a mineral white cast.


Ingredients Analysis

Active Filters

Homosalate ChemicalUVB

Laboratory studies indicate homosalate may act as an endocrine disruptor by interfering with hormone systems [1.1].

Octinoxate ChemicalUVB

Studies indicate potential estrogenic and thyroid disrupting activity in animal models and human cell lines.

Uvinul A Plus ChemicalUVA II / UVA I

Not approved by the US FDA as a sunscreen active and subject to strict EU impurity limits for the reproductive toxicant di n hexyl phthalate.

Key Inactive Ingredients

Ethanol AlcoholSolvent

High concentrations can strip the skin of natural lipids and cause dryness, occasionally leading to irritant or allergic contact dermatitis in sensitive individuals [1.7].
