Why Brands Struggle with Aerosol & OTC Scaling
Producing beauty sprays and OTC drugs is fundamentally different from standard skincare. Without specialized chemical engineering, brands face massive failure rates.
Regulatory & OTC Monograph Pitfalls
Sunscreen sprays and antiperspirants sold in North America must comply with strict FDA 21 CFR drug standards. Lack of cGMP registration or NDC listing delays customs clearance and leads to product seizures.
Valve Clogging & Formula Degradation
Sub-par matching between valve, actuator, and propellant causes white spots, valve blockage, pressure leakage, and uneven aerosol dispersion during the consumer’s usage cycle.
Stringent Multi-Region VOC Caps
California CARB, OTC State Model Rules, and EU eco-regulations impose strict volatile organic compound caps. Formulating high-performance dry shampoos or hairsprays under 55% VOC requires deep R&D.
The Ronghui Aerosol & Spray Delivery Platform
We don't just fill cans — we engineer complete delivery systems integrating propellant, valve mechanics, active ingredient stability, and spray cone ergonomics.
Micro-Mist Particle Sizing
Laser diffraction droplet testing guarantees an ultra-fine, uniform mist cone that delivers instant absorption, non-greasy skin feel, and zero inhalation discomfort.
Bag-on-Valve (BoV) 360°
100% continuous 360-degree spraying powered by eco-friendly compressed air or nitrogen. Formulations remain vacuum-sealed from propellants for clean and preservative-free claims.
Pre-Tested OTC Monograph
Battle-tested broad-spectrum SPF 30 & SPF 50+ formulations verified under FDA OTC rules, water-resistant for 80 minutes, reef-friendly, and validated with USP 51 challenge testing.
In-House HPLC & GC Audit
Audit-trail chromatography instruments ensure active sunscreen agent uniformity, residual benzene elimination, and accurate batch stability testing in real time.
