Cosmetic Chemistry & Stability Testing

At Orivida Research, we provide cosmetic chemistry and stability testing services to help brands evaluate formulation quality, product consistency, and long-term stability. Our testing services support product development, quality control, and safety assessments for cosmetic and personal care products

Heavy Metals Testing

Heavy metals testing identifies and measures trace metal contaminants that may be present in cosmetic raw materials and finished products. Testing can include lead, arsenic, cadmium, and mercury, which may be introduced through raw materials or manufacturing processes.

Testing helps brands assess potential contamination, verify product specifications, and support cosmetic safety and quality requirements.

pH Testing

pH testing measures the acidity or alkalinity of cosmetic formulations, helping brands maintain product consistency and evaluate formulation compatibility.

Testing is commonly performed on creams, lotions, shampoos, conditioners, and other water-based formulations. It supports quality control, formulation development, and stability evaluations.

Viscosity Testing

Viscosity testing measures a cosmetic product's resistance to flow, providing information about its thickness and consistency. It is commonly used for creams, lotions, gels, shampoos, and conditioners.

Testing helps brands monitor batch-to-batch consistency, verify product specifications, and identify changes in formulation stability.

Specific Gravity Testing

Specific gravity testing compares the density of a cosmetic formulation to the density of water under defined conditions.

This measurement helps brands verify formulation specifications, monitor manufacturing consistency, and evaluate changes during stability testing.

Cosmetic Stability Testing

Stability testing evaluates how cosmetic formulations change over time under controlled storage conditions. Studies can include accelerated testing at elevated temperatures, real-time testing under normal storage conditions, refrigerated storage, and freeze-thaw cycling.

Products are evaluated at predetermined intervals for changes in appearance, color, odor, pH, viscosity, specific gravity, and weight loss, as applicable.

Stability studies help brands identify potential formulation changes, evaluate product quality over time, and generate supporting data for shelf-life assessments.

Packaging Compatibility Testing

Packaging compatibility testing evaluates how cosmetic formulations interact with their intended packaging during storage. Studies assess potential changes, including discoloration, leakage, deformation, weight loss, and product deterioration.

Testing helps brands identify compatibility concerns and evaluate whether packaging is suitable for the formulation throughout its intended shelf life.
