To use the Product Manager it is important that you understand the principle of entering %w/w amounts in your formula composition. This is the industry-standard method for formulation of cosmetic products and the method that is used in the software. However, if you prefer to formulate by weight/volume (even in drops), we have a tool for this. For further information please read the blog article on %w/w concentrations and the Product Manager Getting Started Guide.
