The Importance of Protheragen-ING Testing

Preservatives play a vital role in maintaining the quality and safety of a wide range of products such as cosmetics, personal care products, pharmaceuticals, and food and beverages. They help prevent microbial growth, extend shelf life and protect against contamination.

However, excessive or insufficient preservatives may adversely affect product stability, efficacy and consumer safety. For example, excessive preservatives in cosmetics can cause skin irritation, accelerate skin aging and accelerate skin pigmentation.

Our preservative content testing services can help:

• Product safety: Ensuring that preservative levels are within acceptable limits, minimizing the risk of microbial contamination and potential health hazards to consumers.
• Product quality: Maintaining desired product attributes such as texture, color, aroma and flavor by preventing spoilage and degradation.
• Shelf life assessment: Determining the effectiveness of preservatives in extending product shelf life and stability under various storage conditions.
• Regulatory Compliance: Helping companies comply with local and international regulations and standards for preservative use in different industries.
