Introduction: The Role of Silicones in Elevating Sensory Performance
Silicones represent one of the most versatile families of synthetic polymers in modern materials science. Derived from the organosilicon backbone (Si–O–Si) with organic substituents, silicones combine unique chemical inertness with highly tunable physical properties.
Beyond their widespread use as lubricants, sealants, and coatings, silicones play a transformative role in sensory engineering—particularly within personal care, consumer goods, coatings, and high-performance industrial systems.
At the heart of their value proposition lies their ability to engineer texture, glide, spreadability, and after-feel—parameters that are increasingly recognized as essential differentiators in modern formulations.
At RawSource, we deliver this innovation through advanced chemical blending solutions that allow formulators to achieve precision performance, sensory differentiation, and regulatory compliance.
Unlocking Texture with Advanced Silicone Systems
1. Silicone Elastomers
Silicone elastomers—crosslinked polydimethylsiloxane (PDMS) networks—are the foundation of texture engineering. Available as gels, powders, and dispersions, elastomers impart:
- Cushion-like textures through their ability to deform under pressure while retaining structure.
- Oil absorption for sebum control and mattifying effects in cosmetics.
- Enhanced spreadability when dispersed in carriers such as cyclopentasiloxane or dimethicone.
Their tunability enables formulations ranging from lightweight serums to rich, velvety creams, as well as smooth-feel coatings in industrial settings.
2. Silicone Blends
Blending volatile and non-volatile silicones creates dynamic sensory cascades. Volatile dimethicones provide immediate spreadability and quick-dry feel, while heavier PDMS oils deliver long-lasting slip. By adjusting the volatility profile, chemists can choreograph the sensory journey from application to after-feel.
3. Viscosity Modifiers
Silicones act as rheology modifiers through controlled molecular weight distribution. High-viscosity PDMS contributes body and film formation, while low-viscosity fluids enhance flow and spread. Silicone polyethers further enable emulsification and viscosity stabilization across polar and non-polar systems.
Applications:
- Skincare lotions with balanced glide and absorption.
- Automotive polishes with durable gloss and smooth buffing.
- Lubricants engineered for low start-up torque and long-lasting film stability.

How Silicones Enhance Glide, Spread, and After-Feel
Through their low surface tension, controlled volatility, and flexible polymer backbones, silicones reduce friction, optimize spreading across surfaces, and impart lasting after-feel—qualities critical in skincare, haircare, lubricants, and coatings.
- Glide: Their flexible backbones reduce drag, ensuring smooth application.
- Spreadability: Their low surface tension allows even distribution across surfaces.
- After-feel: Their volatility profile allows engineers to fine-tune sensory outcomes—from powdery matte to velvety rich.
Designing Sensorial Experiences with Performance in Mind
Performance and perception are tightly intertwined. Advanced silicone systems allow chemists to move beyond functionality, creating products that not only perform technically but also deliver superior sensory experiences.
Examples include:
- A skincare primer where silicone elastomer gel provides a blurring, cushiony texture.
- Automotive coatings with silicone additives that improve slip and gloss durability.
- Medical adhesives where silicone enables strong adhesion but gentle removal.
