The target was to replace other plastic containers with more modern, eye-catching design and lighter, more flexible PET containers. Higher
productivity, lower raw-material cost, better neck-finish definition, better safety are some other advantages of using PET. Detergents may be in any form: liquid, powder, paste, bar, cake, moulded piece, shape etc. and they are composed of core components such as: surfactants, chelants and buffer; performance additives such as bleach, polymer and enzymes and ingredients such as perfume and brighteners. In fact some of the performance additives and aesthetic ingredients are sensible to UV light and need to be protected.
