The Foundation of Cosmetic Excellence: ISO 9001, ISO 14001 & ISO 45001 Explained

In today's competitive beauty landscape, product consistency and safety have become the cornerstones of successful brand partnerships. International Organization for Standardization (ISO) certifications provide a globally recognized framework that ensures manufacturing processes meet rigorous standards across quality management, environmental responsibility, and workplace safety.

From Raw Materials to Finished Product: The Ousan Quality Control Journey

Ousan's 35-color eyeshadow palette exemplifies how ISO standards translate into tangible product benefits. The manufacturing process implements a multi-layered quality control protocol that begins long before production starts.

1. Raw Material Selection & Verification

Every ingredient undergoes 17 individual tests for heavy metals, microbiological contamination, and stability. This rigorous screening process ensures that only 3% of initial raw material candidates make it to production—far exceeding the industry average of 12% rejection rate.

2. In-Process Quality Monitoring

During manufacturing, automated systems perform 24 quality checks per production hour, with real-time data analysis that triggers immediate corrective actions for any deviation beyond 0.3% of standard parameters. This continuous monitoring is why Ousan maintains a 99.7% batch consistency rate.

3. Finished Product Testing

Each production run undergoes comprehensive safety testing, including dermatological assessments, stability testing under extreme temperature conditions (-10°C to 45°C), and packaging integrity verification. These protocols have resulted in zero product recalls in the past 5 years.

Technical Documentation: Building Trust Through Transparency

Beyond manufacturing excellence, professional technical documentation plays a pivotal role in establishing supplier credibility. Ousan provides comprehensive product dossiers that include:

• • Complete ingredient lists with INCI names and CAS numbers
• • Stability test reports spanning 18 months
• • Safety data sheets compliant with EU CLP and US SDS standards
• • Clinical test results for skin irritation and sensitization

This level of documentation not only facilitates market entry across regions with varying regulatory requirements but also reduces client onboarding time by an average of 40% compared to suppliers with incomplete documentation.

Beyond Production: The Ousan Service Difference

Exceptional manufacturing is just the beginning of a successful OEM/ODM partnership. Ousan's client-centric service model addresses the unique challenges beauty brands face when launching new products:
