For cosmetic products that need to withstand water, sweat, or humidity—such as mascaras, eyeliners, sunscreens, and long-wear foundations—water-resistant film-forming agents are essential, and SHENGRUIXIANG’s Water-Resistant Film-Forming Agent category delivers top-tier solutions. Our film-forming agents create a thin, flexible barrier on the skin or hair that repels water without feeling heavy or clogging pores. Unlike low-quality alternatives that may flake or smudge, our agents form a uniform film that adheres well to the skin’s surface, maintaining product integrity for hours. We offer both synthetic and natural (plant-derived) options, with the latter ideal for clean beauty lines. Our range includes agents optimized for different products: for example, mascara-specific agents that resist tears and eye moisture, and sunscreen agents that maintain UV protection even after swimming. Each agent is tested for water resistance (per FDA and EU standards) and safety (non-irritating to sensitive skin, especially around the eyes). We also provide guidance on formulation ratios—too much agent can make products stiff, while too little reduces water resistance. Additionally, our film-forming agents are compatible with common cosmetic ingredients, ensuring easy integration into existing formulations. SHENGRUIXIANG’s Water-Resistant Film-Forming Agents help brands create products that offer long-lasting performance, meeting consumer demand for reliable, low-maintenance cosmetics.
