Description

Vitamin C (Ascorbic Acid) is a widely used active ingredient in skincare, food, and nutraceutical formulations due to its antioxidant and collagen-boosting properties. However, it is highly unstable and sensitive to light, heat, and air, making proper testing crucial to ensure product effectiveness and shelf-life.

Our laboratory offers comprehensive Vitamin C testing across cosmetics, pharmaceuticals, and food products using advanced techniques like HPLC, UV-Vis spectrophotometry, and titration methods. We test for:

  • Vitamin C concentration

  • Stability and degradation analysis

  • Shelf-life evaluation

  • Label claim verification

Whether you’re formulating a face serum, supplement, or fortified drink, our accurate and validated testing helps you ensure product safety, consumer trust, and regulatory readiness.
