Active Ingredients: Avobenzone 3.0% Homosalate 10.0% Octisalate 5.0% Inactive Ingredients: Aqua/Water/Eau ●
TL;DR. This is a chemical sunscreen it blend that absorbs UVA and UVB radiation, with water serving as the carrier phase. Its primary role is broad-spectrum UV protection in leave-on sun-care products.
What does Active Ingredients: Avobenzone 3.0% Homosalate 10.0% Octisalate 5.0% Inactive Ingredients: Aqua/Water/Eau do in a cosmetic formula?

Is Active Ingredients: Avobenzone 3.0% Homosalate 10.0% Octisalate 5.0% Inactive Ingredients: Aqua/Water/Eau clean?
Clean-beauty frameworks often flag this filter system because one component has endocrine-screening and regulatory concentration-limit scrutiny, and several retailers restrict formulas using this type of it blend. It is generally compatible with skin, but eye stinging and sensitivity can occur in some users.
Is Active Ingredients: Avobenzone 3.0% Homosalate 10.0% Octisalate 5.0% Inactive Ingredients: Aqua/Water/Eau sustainable?
This material is primarily synthetic and typically derived from petrochemical feedstocks, apart from the aqueous carrier. Many aromatic UV absorbers are not readily biodegradable and can raise aquatic persistence questions, especially in rinse-off or high-exposure beach-use contexts.
Is Active Ingredients: Avobenzone 3.0% Homosalate 10.0% Octisalate 5.0% Inactive Ingredients: Aqua/Water/Eau COSMOS-approved?
This filter system is not permitted for COSMOS-natural or COSMOS-organic certification, which generally favors mineral UV filters for certified sunscreen products. From a Green Chemistry perspective, it has weaker alignment because of synthetic petrochemical sourcing, limited biodegradability, and photostability requirements.
How does Active Ingredients: Avobenzone 3.0% Homosalate 10.0% Octisalate 5.0% Inactive Ingredients: Aqua/Water/Eau work chemically?
It combines one UVA-focused beta-diketone absorber at 3% with two UVB-focused ester absorbers at 10% and 5% in an aqueous base. The UVA component is photolabile unless paired with stabilizers, antioxidants, or compatible film formers, while the UVB ester components are oil-soluble and usually require emulsifiers or solubilizers in water-based formulas.
