BioSulphur Solubility and Soft Cream Maker Stability with Electrolytes

Question

I have two questions regarding raw materials:

BioSulphur™ EQ Mixing: The product page states conflicting information about how to mix BioSulphur™ EQ. One section says "Mix in the water phase, highly tolerant to acid-base (pH 2-11)" but another line says "Solubility: Soluble in oil, dispersible in cream/gel/serum formulations." I am confused about how to use it correctly as I plan to purchase it.
Soft Cream Maker™ and Electrolyte Tolerance: Can Soft Cream Maker™ tolerate electrolytes? (I previously asked and the team responded about Satin Cream Maker™). I am formulating a cream with the following ingredients:
- Water
- Aloe Vera Extract (10:1 FullAssay™) 5%
- B3 (Niacinamide) 5%
- B5 (Panthenol) 3%
- Argan Oil (Organic - Virgin - Deodorized) 4%
- Soft Cream Maker™ 5%
- Glyceryl Stearate SE / Glyceryl Monostearate SE 2%
- Preservative (Phenonip® P4) 0.8%
The cream turned out liquid like water and has not thickened even after 5 days. Please advise.

Regarding your questions about your cream formulation:

BioSulphur™ EQ Mixing

There seems to be a slight confusion on the product page regarding the mixing method for BioSulphur™ EQ. Based on its properties, BioSulphur™ EQ is water-soluble and should be mixed into the water phase of your formulation. It has a wide pH tolerance (pH 2-11). Please note that it should not be used with Vitamin C (Ascorbic Acid) as they can react.

Soft Cream Maker™ and Electrolytes

You are correct that you previously inquired about Satin Cream Maker™. Regarding your current formula using Soft Cream Maker™ and the issue of it not thickening, this is likely due to the presence of electrolytes in your formulation.

Both Aloe Vera Extract and Niacinamide (Vitamin B3) are electrolytes. The description for Aloe Vera Extract specifically mentions that it can cause gels or creams to become soft or liquid. Soft Cream Maker™ is sensitive to electrolytes, which can interfere with its ability to form a stable emulsion and thicken the cream.

Satin Cream Maker™, which you mentioned previously, is specifically designed to be electrolyte resistant and would be a more suitable emulsifier for a formula containing ingredients like Aloe Vera Extract and Niacinamide.

To achieve a stable cream texture with your desired ingredients, we recommend using Satin Cream Maker™ instead of Soft Cream Maker™.
