The water phase forms the bulk of lotions, creams, serums, and cleansers. It acts as the solvent for water-soluble ingredients.
Measuring by percentage allows formulators to strictly adhere to maximum usage rates for potent ingredients like essential oils or preservatives, preventing skin sensitization.
Creating a cream or lotion involves a specific thermal process called hot-pour or hot-emulsification. Follow these precise steps:
