![]() The Emulsion Calculator Excel Worksheet also provides a table on basic starter formulas for home-crafters for lotion, moisturizer and body butter for various skin types. Enter the percentage of each Ingredient, and both water and oil phases will be calculated.Ĭool Down Phase: This phase is for antioxidants, fragrances, essential oils, and preservatives. Oil Phase: Enter all ingredients that would be included in this phase. Since water percentage is automatically calculated, the total of the formula will always equal 100%. Water Phase: Enter all ingredients that go into the water phase. Next, print out the page and the recipe is ready! By entering the size of the batch, the weight of each ingredient for the formula will be calculated. All ingredients are added to the phases by using the available drop-down menus. This calculator requires only the input of the ingredients and percentages and will save much precious time to calculations by hand. Emulsion Calculator is designed for O/W emulsions. The Emulsion Calculator is an Excel Worksheet that quickly and easily allows the formulator to calculate the requirements for emulsion. Make beautiful lotions and creams with this handy calculator! O/W emulsions tend to be less cost-effective, as oils are always more costly than water and these type of emulsions are generally more challenging to produce. W/O emulsions have a high oil concentration, whereas O/W emulsions have a low oil concentration. The main difference between the 2 emulsions is the proportion of the liquid phase is higher in O/W emulsions. They often leave a lubricious, rich, and oily feeling when applied to the skin. – W/O emulsions provide better protection, especially important for mature and dry skin, and night care. – O/W emulsions feel lighter over the skin because the water phase is the outer phase, emulsions are either liquid (lotions and milks) or semi-solids (creams). ![]() Water phase could be water or any other hydrophilic liquid i.e., hydrosols and the oil phase could be consisting of any lipophilic substance (or a blend of a few of them) such as oils and butters.Īn emulsion is either of water-in-oil (W/O) or oil-in-water type (O/W), depending on the proportion of the outer phase and type of emulsifier used. An emulsion is a heterogeneous system of two immiscible liquids (water and oil phase), one of which is dispersed as liquid droplets (i.e., the inner or dispersed phase) in the other (i.e., the outer or continuous phase).
