Description: STUDIES OF PHARMACY, COSMETIC & FOOD PRODUCTS Studies of pharmacy, cosmetic and food products are essential to determine the type of packaging, quality and shelf life. Free water available in the product determines the stability. More the free water, more are the chances of microbiological or fungi growth on it.
