Cosmetic Stability Testing Services

In the highly competitive and rapidly growing cosmetic industry, brand differentiation is no longer defined solely by having a “good formulation,” but by the ability to maintain consistent product quality over time.

Cosmetic Stability Testing is a scientific process designed to verify that a cosmetic product retains its original characteristics throughout its intended shelf life. This includes physical appearance, color, odor, texture, viscosity, active ingredient performance, and—most critically—consumer safety.

At TIBD Co., Ltd., we provide end-to-end cosmetic stability testing services, supported by laboratories purpose-built for the health and beauty industry. Our multidisciplinary team brings over 14 years of hands-on experience in cosmeceutical R&D and technology management, delivering scientific data that can be translated into confident, data-driven business decisions.

A product that appears stable at the time of manufacturing may undergo significant changes within months if stability is not properly evaluated. Even subtle variations, such as color fading, odor changes, or emulsion separation, can significantly damage brand credibility and consumer trust.

Stability testing enables brands to scientifically assess whether the product maintains its original condition under various storage environments, whether active ingredients remain effective at the intended concentration, whether microbial contamination or hazardous degradation occurs, and whether the product’s official shelf life can be validated and declared with confidence.

TIBD’s laboratories are designed and operated in accordance with ISO/IEC 17025 quality management principles, ensuring precise control of temperature, humidity, and light exposure to accurately simulate real-world market conditions.

Our stability testing program follows international best practices aligned with the ASEAN Cosmetic Directive and COLIPA guidelines, covering six standard test conditions:

1. Room Temperature Storage at 25 ± 2°C, simulating normal storage in retail environments and consumer households.

2. Accelerated High-Temperature Testing at 40 ± 2°C, accelerating potential formulation changes to predict long-term stability.

3. Low-Temperature Storage at 4 ± 2°C, evaluating crystallization, phase separation, or texture instability.

4. Temperature Cycling or Freeze–Thaw Testing, alternating between high and low temperatures to simulate transportation and climate variation.

5. Direct Sunlight Exposure using a Xenon Arc Lamp to assess color change, odor alteration, and photodegradation.

6. Indoor Light Exposure using high-intensity LED lighting to simulate retail display conditions.

Samples are collected and analyzed at predefined intervals of 0, 1, 3, 6, 9, and 12 months to assess both short-term and long-term product stability.

To ensure results reflect real-world performance, TIBD conducts comprehensive physical, chemical, and microbiological analyses, including physical appearance such as color, odor, texture, foaming, and phase separation.

pH is measured using calibrated pH meters to confirm skin compatibility. Viscosity is evaluated using viscometers to detect texture or flow changes.

Active ingredient assays are conducted using analytical techniques such as High-Performance Liquid Chromatography and UV–Visible Spectrophotometry.

Microbial Limit Testing is performed in compliance with ISO 17516:2014 to confirm product safety. Preservative Efficacy Testing verifies antimicrobial performance throughout the product’s shelf life. Packaging compatibility testing assesses potential migration, discoloration, or material interaction.

TIBD is not merely a testing service provider. We act as a technology management and commercialization partner, enabling health and beauty brands to leverage scientific data as a strategic business asset.

Through our science and business integration approach, stability testing results are transformed into technology intelligence, empowering clients to develop product and technology strategies aligned with target markets, translate research outcomes into commercially viable product designs, evaluate formulation readiness prior to market launch, and define shelf life and quality benchmarks for regulatory, investor, and partner communications.

Our team integrates expertise across biotechnology, cosmetic chemistry, technology management, and market strategy, enabling brands to convert testing data into scalable growth strategies and internationally competitive innovations.

• Enhanced consumer and partner confidence through certified laboratory data validating product quality.

• Reduced business risk by preventing quality degradation, complaints, and product recalls.
