Texture Enhancers for Water-Based Sunscreen (Silicone-Free)

To improve the soft, smooth feel and spreadability of a water-based sunscreen without using silicones or alcohol, while ensuring it is non-irritating, you can consider using specific types of water-soluble polymers or gelling agents.

One ingredient that can help achieve this is Sepimax Zen.

• Sepimax Zen (Polyacrylate Crosspolymer-6) is a synthetic polymer that functions as a thickener and emulsion stabilizer. In water-based formulas, it creates a gel texture that can significantly improve the feel and spreadability, providing a smooth, non-tacky application. It is known for its tolerance to salts and varying pH levels, making it suitable for complex formulations like sunscreens. It is generally considered non-irritating and is a good alternative to traditional thickeners when seeking enhanced texture and slip in silicone-free systems.

By incorporating ingredients like Sepimax Zen into the water phase, you can create a more pleasant texture that glides easily onto the skin, addressing the need for a soft, smooth, and easy-to-spread sunscreen.
