Understanding Cream Maker Usage and Oil Emulsification

Regarding your questions about cream makers and their ability to emulsify oil:

1. Maximum Oil Percentage: Yes, when a cream maker states it can emulsify up to a certain percentage of oil (e.g., 10% for Rich Cream Maker), this percentage refers to the amount of oil within the total 100% of your formula. Your example calculation (Water 87%, Oil 10%, Rich Cream Maker 3%) correctly represents this, where the oil phase is 10% of the overall formula.

2. Effect of Increasing Cream Maker Percentage: Increasing the concentration of the cream maker within its recommended usage range can help to emulsify a slightly higher percentage of oil. However, this effect is not drastic or linear. The type of oil being used also significantly impacts how easily it can be emulsified. For instance, using 3% Rich Cream Maker might emulsify 5-7% oil, while using 5% might emulsify 5-10% oil. For formulas requiring a high oil content, it is often better to choose a cream maker specifically designed for higher oil loads, such as Luxury Cream Maker.

3. Applicability to Other Cream Makers: This general principle applies to most other cream makers as well. Using a higher amount within the recommended range can slightly enhance oil emulsifying capacity. However, be cautious not to exceed the recommended maximum usage for any cream maker, as using too much can lead to undesirable effects. For example, using too much Light Cream Maker can cause the product to pill or create a residue on the skin when applied.

In summary, while slightly increasing the cream maker concentration can offer a minor boost in oil emulsification, it's crucial to consider the specific properties of the cream maker and the type of oil. For high oil percentages, selecting a cream maker designed for that purpose is recommended.
