1. Formulation Development & Optimization

• Develop and optimize formulations for various skincare products, including emulsions (oil-in-water, water-in-oil), gels, serums, suspensions, anhydrous systems, and surfactant-based cleansers.

• Select and balance emulsifiers, humectants, emollients, preservatives, and active ingredients based on stability and efficacy.

• Conduct pre-formulation studies, including solubility analysis, pH optimization, and compatibility testing.

• Perform forced degradation studies to predict formula stability under different conditions.

• Optimize the Hydrophilic-Lipophilic Balance (HLB) of emulsions for improved consistency and texture.

• Troubleshoot formulation issues such as viscosity drift, phase separation, air entrapment, and active ingredient degradation.

2. Analytical & Performance Testing

• Stability & Compatibility Testing:

• Perform accelerated stability testing at multiple temperatures (4°C, 25°C, 40°C, 45°C, and freeze-thaw cycles).

• Assess phase separation, viscosity changes, pH drift, and microbial contamination over time.





• Conduct oxidative stability testing (e.g., peroxide value analysis) for oil-based formulations.

• Evaluate packaging compatibility for leaching, sorption, and migration of active ingredients.

• Microbiological & Preservative Efficacy Testing:

• Conduct Preservative Efficacy Testing (PET/Challenge Tests) as per USP , ISO 11930, or Ph. Eur. 5.1.3 standards.

• Ensure compliance with Positive Manufacturing Practices (GMP) to prevent microbial contamination.

• Rheological & Sensory Analysis:

• Perform rheology measurements using viscometers and rheometers to determine shear-thinning or shear-thickening properties.

• Analyze spreadability, adhesion, and absorption rates using texture analyzers.

• Conduct panel testing to assess sensorial attributes such as skin feel, absorption rate, and after-feel effects.

• Active Ingredient Efficacy Testing:

• Measure penetration and bioavailability of ac
