CasEmol – Biodegradable Alternatives to Silicone Emollients and Cyclic Siloxanes

CasEmol paraffinic emollients provide high-performance, biodegradable alternatives to silicone-based ingredients, specifically cyclic siloxanes such as Cyclotetrasiloxane (D4), Cyclopentasiloxane (D5), and Cyclohexasiloxane (D6), which are increasingly facing regulatory restrictions.

What Is CasEmol?

CasEmol is a range of biodegradable paraffinic emollients developed to replace commonly used silicones in cosmetic and personal care formulations. Produced from ultra-high purity linear alkanes, the CasEmol line delivers:

Sensory versatility – from dry-touch to rich, cushiony textures
High spreadability and low viscosity
Excellent oxidative stability
Compatibility across a broad pH range

Whether you’re targeting light, silky slip or deep moisturising richness, CasEmol provides the formulation flexibility you require.

Why Move Away from D4, D5 and D6?

These ingredients have been flagged by regulators in the EU and other markets for their persistence, bioaccumulation, and potential toxicity. Their use is increasingly limited or restricted – prompting formulators to seek compliant, sustainable alternatives.

Formulating Without Compromise

CasEmol emollients are designed as drop-in replacements for common silicones. They offer the same luxurious skin feel, sensory profile and technical performance – while meeting the growing demand for biodegradable, regulatory-friendly ingredients.

Backed by Supply Chain Confidence

CasEmol is supported by:

An independent, integrated supply chain
Global network – sales offices, direct logistics
Full regulatory support, including REACH
