A cream is a water in oil or oil in water solution that has been blended together with the help of a mixing agent called an emulsifier. Naturally, oil and water don't mix. Emulsifiers have a water-loving and an oil-loving side to it that helps to attract and bind the two phases.
A traditional cream requires to heat both phases to a high temperature to ensure all solid ingredients melt then you combine one phase into the other while mixing. It takes quite a lot of energy to heat and mix. Most conventional creams are made this way. There are a lot of different types of emulsifiers on the market. Some are 100% chemical and others are 100% natural.
I've tried all kinds of emulsifiers and still looking for the right one. Email email@example.com if you are interested in testing out some of our formulas that are in the works. Until supplies last.
