The quality of the water used in manufacturing cosmetic products is absolutely crucial, especially if you are producing for the export market. Many cosmetic products begin as concentrations which must be watered down before being placed into packaging, so that chemical reactions can be avoided. Also, water used in the cosmetics industry must be as pure as possible, so as to prevent the proliferation of bacteria.
All British cosmetic companies have to comply with UK and EU manufacturing quality regulations. However, if you sell your products to the USA you also need to comply with standards set out by the US Food and Drug Administration (FDA). Under this legislation, water is considered to be a raw material in the cosmetics manufacturing process.
