Continuous propellant-free multi-orifice spray system for personal care products
A sustainable, propellant-free spray system utilizing a spring-actuated mechanism and multi-orifice nozzle for personal care applications. It ensures precise droplet formation without gases, offering an eco-friendly alternative that mimics traditional aerosol performance.
Overview
The continuous propellant-free multi-orifice spray system is an innovative solution designed for personal care applications. Utilizing a spring-actuated mechanism paired with a multi-orifice nozzle, this system achieves precise and controlled droplet formation without the need for compressed gases. This eliminates the cold, gassy sensation associated with traditional aerosols. It is engineered to handle a wide range of fluid viscosities while maintaining consistent spray uniformity and sensory quality. This technology offers a sustainable and environmentally conscious alternative to conventional aerosols by reducing reliance on volatile propellants, thereby minimizing greenhouse gas emissions.
