The filtration of toiletry and cosmetic ingredients is a readily understood process ranging from clarification of creams and ointments to sterile filtration of water used for product preparation.
Cosmetics typically require filtration for purposes of clarity, bacterial reduction and PoF (point of filling) security. During the process of blending of the raw materials and constituents, the protection from contaminants within the closed and external environments or transfer of products in the process is critical.
Preparations require a varied intensity of filtration depending on the level of clarity and sterility of the finished product. Products range from creams, water or solvent based lotions, eau-de-colognes, perfumes, mouth washes to shampoos. As these products are for application within the public domain, quality and compliances will be of paramount importance requiring validated and certificated filtration products.
