Preservatives are used in products to keep them safe and protect them from microbial growth (i.e., mold and bacteria). Though preservatives often get a bad reputation, they are very important to ensure product safety. There are many different types of preservatives. We comply with all safety regulations for all markets in which we are sold and choose the best preservatives for each product. Some that we do not formulate with are parabens, methylisothiazolinone (MI) / methylchloroisothiazolinone (MCI) and formaldehyde releasing preservatives such as DMDM hydantoin.
