Performance & Formulation Insights for Etocrylene

How Etocrylene Works as a Photostabilizer

Etocrylene is an organic UV filter that absorbs UVB and short-wave UVA radiation. It safeguards cosmetic products by absorbing high-energy UV photons and converting them into low-energy heat, which is dissipated harmlessly. Critically, Etocrylene acts as a superior photostabilizer, especially for Avobenzone, helping it return to its ground state after UV exposure. This reduces photodegradation, allowing Avobenzone to continue providing consistent UVA protection. The synergy between Etocrylene and other filters is key to maintaining broad-spectrum efficacy and overall formula performance under sunlight.

Formulation Guidelines for Optimal Performance

Etocrylene is an oil-soluble, white crystalline powder that should be incorporated into the oil phase of emulsions. Gentle heating of the oil phase aids complete dissolution. It is stable across the typical cosmetic pH range and is suitable for anhydrous systems, emulsions, and oil-based serums. For general product stabilization (protecting fragrances, colors, and sensitive actives), use 1–5%. In regions where approved as a sunscreen active (e.g., the EU), it may be used up to 10% for primary UV protection. Its compatibility and low impact on aesthetics make it easy to integrate into a variety of formats.

Key Formulation Benefits

Superior Photostabilization: Significantly enhances the stability and performance of other UV filters, especially Avobenzone, for reliable, long-lasting protection.
Formula Integrity: Helps prevent UV-driven fading of colors, shifting of fragrances, and breakdown of light-sensitive actives within the product.
Broad Compatibility: Works seamlessly with common emulsion systems and oil-based formats; straightforward to incorporate into the oil phase.
Enhanced Shelf Life: Shields products from light-induced deterioration, supporting both functional performance and aesthetic longevity.
Versatile Application: Suitable for sunscreens, daily moisturizers, color cosmetics, hair care, and fragrance products.
Aesthetically Neutral: Dissolves to a clear, odorless state without impacting the final look or scent of formulations.

Frequently Asked Questions About Etocrylene

Etocrylene serves a dual purpose: it absorbs UV radiation to protect the product itself, and it photostabilizes other UV filters (like Avobenzone), making the entire sunscreen system more effective and stable.

It is oil-soluble and should be dissolved in the oil phase of your formulation, typically with gentle heating.

For protecting a formula’s color, fragrance, or other actives, use 1–5%. Where permitted as a primary sunscreen active, it can be used up to 10%.

Avobenzone is a strong UVA absorber but is highly unstable under UV exposure. Etocrylene helps stabilize Avobenzone by mitigating its photodegradation, allowing continuous, effective UVA protection.

Yes. It is valuable in daily moisturizers, foundations, and other leave-on products to protect light-sensitive ingredients (antioxidants, vitamins, natural extracts) from degradation in-pack and on skin.

Its primary role is to protect and stabilize the formulation. By improving sunscreen system stability, it indirectly supports more reliable protection against UV-related skin damage.
