Emulsifier Compatibility with Electrolytes in Cream
Question
Regarding Sensitive Cream Maker™ and Glyceryl Stearate Citrate, can they tolerate electrolyte substances?
I plan to include Aloe Vera Extract at 10% in the formulation, but I want a cream base that is gentle on the skin. I am interested in these two ingredients.
Answer
Based on the information from the product descriptions:
Both Sensitive Cream Maker™ and Glyceryl Stearate Citrate are described as gentle emulsifiers suitable for sensitive skin and are PEG-free.
However, the description for Aloe Vera Extract (extraction ratio 10:1 FullAssay™) explicitly states that it is an electrolyte and may cause some gels or creams to become soft or liquid, especially at concentrations like 10%.
The descriptions for Sensitive Cream Maker™ and Glyceryl Stearate Citrate do not specifically mention their tolerance to electrolytes. While Sensitive Cream Maker™ has a broad pH tolerance (4-9) and Glyceryl Stearate Citrate is described as highly stable with a pH range of 5.0-8.0, the presence of electrolytes from 10% Aloe Vera Extract could still potentially affect the stability or viscosity of the final formulation.
Therefore, while both are gentle options, it is highly recommended to perform stability testing with your specific formulation containing 10% Aloe Vera Extract to ensure the cream remains stable and has the desired texture over time.
