AccessSIL FF-15

High-Performance Film Former for Long-Lasting, Water-Resistant Formulations

INCI Name: Cyclopentasiloxane (and) Acrylates / Dimethicone Copolymer

AccessSIL FF-15 is a powerful silicone film former that delivers exceptional longevity and resistance to water, sweat, and oil. The volatile cyclopentasiloxane carrier provides a lightweight, silky application that flashes off, leaving a flexible, breathable film to lock pigments and actives in place. Ideal for long-wear foundations, water-resistant sunscreens, and transfer-proof lip colors.

Perfect For These Applications

Other cosmetic uses possible—contact us for formulation guidance.

Long-Wear Foundations & Concealers

Creates a transfer-resistant, flexible film that maintains coverage throughout the day without feeling heavy, dry, or cakey.
Water-Resistant Sunscreens

Significantly improves water and sweat resistance, helping SPF and UV filters remain on the skin during swimming or outdoor activities.
Transfer-Proof Lip Stains & Liquid Lipsticks

Forms a durable, non-tacky film that prevents color from smudging, feathering, or transferring for true all-day wear.
Protective Skin Serums & Primers

Delivers a smooth, breathable barrier that protects from environmental aggressors and creates a perfect canvas for makeup.
Smudge-Proof Eye Makeup

Enhances wear-time of eyeliners, mascaras, and cream shadows, helping prevent smudging and creasing from oils or humidity.
Protective Hand Creams

Provides a “glove-like” effect that locks in moisture and helps protect the skin barrier through multiple hand washes.

How to Use AccessSIL FF-15 in Your Formulations

Understanding AccessSIL FF-15

Think of AccessSIL FF-15 as an invisible, flexible shield for skincare and makeup. Its job is to create a thin, durable layer on the skin that keeps pigments, UV filters, and actives in place—delivering long-lasting and water-resistant performance. Without a film former like this, makeup can smudge with sweat or oil, and sunscreens can wash away.

Technically, AccessSIL FF-15 combines two parts that work together. Cyclopentasiloxane is a very lightweight, volatile silicone that spreads easily and provides a silky glide. After application it flashes off, leaving behind the Acrylates/Dimethicone Copolymer—a high-performance film former that links into a stable, breathable mesh. The silicone-acrylate hybrid structure keeps the film soft and flexible, avoiding the tightness or cracking sometimes associated with traditional film formers.

Formulation Tips

Usage depends on desired performance:

Daily wear products (primers, lightweight foundations): 1–5%
High-performance, long-wear products (waterproof sunscreens, transfer-proof lips): 5–15%

How to incorporate:

Emulsions (creams/lotions): Add in the oil phase during cool-down (below 40°C / 104°F) to minimize premature evaporation of the volatile silicone.
Anhydrous systems: Blend directly with silicones, esters, and oils at room temperature.

Compatibility is excellent with silicones, esters, and organic UV filters. It also improves pigment dispersion and adhesion for long-wear, uniform color.

Key Formulation Benefits:

Exceptional Longevity and Wear: Extends wear-time of color cosmetics and sun care, keeping them fresh for hours.
Superior Water and Oil Resistance: Creates a durable, hydrophobic film that resists water, sweat, and sebum for sport-friendly performance.
Comfortable, Flexible Film: Silicone-acrylate network moves with skin to avoid tightness, dryness, or cracking.
Smooth, Silky Sensory Feel: Volatile cyclopentasiloxane carrier provides a non-greasy glide and velvety dry-down.
Enhances Pigment Adhesion: Improves color payoff and reduces transfer onto clothing or glassware.
Versatile Across Formats: Performs in water-free silicone serums and oil-in-water emulsions alike.

Frequently Asked Questions About AccessSIL FF-15

A film former creates a thin, invisible layer on the skin that holds makeup pigments in place, helps sunscreen filters resist wash-off, and adds a protective barrier. It’s the key to achieving long-lasting and water-resistant performance.

Use 1–5% for daily wear products like primers or lightweight foundations. For very long-lasting or waterproof products (e.g., liquid lipstick, beach sunscreen), use 5–15%.

No. It is delivered in cyclopentasiloxane, a very light volatile silicone that evaporates after application, leaving a thin, flexible, non-tacky film with a smooth feel.

For emulsions, add during cool-down below 40°C (104°F). For anhydrous products (e.g., silicone serums), blend at room temperature.

Yes. It’s a silicone-based blend: Cyclopentasiloxane provides the silky application, while Acrylates/Dimethicone Copolymer forms the flexible, durable film.

It is a synthetic silicone-based ingredient and not suitable for certified 100% natural or organic products, but it excels in conventional and high-performance cosmetics.

The resulting film is considered breathable. While individual responses vary, the components are not generally regarded as comedogenic. The volatile carrier evaporates and does not remain on the skin.
