Adding 2% Apple Stem Cell Extract (AppleCell™ Powder) to your formula is generally compatible, with a few considerations regarding pH and mixing.

Compatibility Assessment

Apple Stem Cell Extract (AppleCell™ Powder): This ingredient is water-soluble and should be added in the final step of your formulation process, ensuring the temperature is below 40°C. It requires a pH range of 3.5-6.5 for stability and effectiveness.
Yeast Radiance™: This ingredient is also water-soluble and requires a pH range of 4.0-6.5. It should be mixed in the water phase, avoiding heat.
Mild Preserved Eco™: This preservative works within a pH range of 4-9 and can withstand temperatures up to 80°C for a short time. It's typically added in the final step.
Satin Cream Maker™: This emulsifier works well across a broad pH range (3-12) and is used in a cold process (heat-free). It can emulsify up to 25% oil, and your total oil phase (Flaxseed Oil, Algae Oil, Mint/Rose/Lemon) is 13.5%, which is within this limit.
Other Water-Soluble Ingredients: Albumin egg whites, Rice Vitamin, and WhiteCumin™ 2x are water-soluble and should be compatible with the water phase. Albumin is stated to be soluble up to approximately 4%, so your 2% usage is fine, though higher amounts might cause sedimentation.
Snow Mushroom Hyaluron: This ingredient is water-soluble and recommended for use at 0.1-0.5%. Your usage rate of 1% is higher than recommended, which might lead to solubility issues or sedimentation in the final product.
Oil Phase: Flaxseed Oil and Algae Oil are oils and will form the oil phase of your emulsion, which is handled by the Satin Cream Maker. Phospholipid can be dispersed in oil and should be compatible.

Recommendations

pH Adjustment: To ensure compatibility and effectiveness of both Apple Stem Cell Extract Powder and Yeast Radiance, the final pH of your formula must be adjusted to be within the range of 4.0-6.5.
Mixing Procedure: Add the Apple Stem Cell Extract Powder in the final step of your formulation, after the emulsion has formed and cooled down to below 40°C. Ensure it is fully dissolved or dispersed.
Snow Mushroom Hyaluron: Be aware that using Snow Mushroom Hyaluron at 1% is higher than the recommended maximum of 0.5%. Monitor your formulation for any solubility issues or sedimentation. You may consider reducing the percentage if you encounter problems.
General Mixing: Follow the mixing instructions for Satin Cream Maker by first mixing water-soluble ingredients (except Apple Stem Cell Extract Powder and Mild Preserved Eco) in the water phase, then adding the oil phase containing oil-soluble ingredients and the emulsifier, mixing to form the cream. Add Apple Stem Cell Extract Powder and Mild Preserved Eco in the final cooling phase.

In summary, adding 2% Apple Stem Cell Extract (AppleCell™ Powder) is feasible, provided you manage the final pH and add it correctly in the final step at a low temperature. Pay attention to the higher concentration of Snow Mushroom Hyaluron.
