In addition, it has medium rigidity and good chemical resistance. PET cosmo bottles are perfect for products such as liquids, hair-care, personal care products, and essential oils.

Therefore, Avoid using PET style packaging with products that contain essentials oils greater than 5% percent and fragrance oils greater than 15% percent. If your essential oils percentage is above the recommended limit, we would highly consider using glass.
