Using Acacia Gum and Vitamin C Powder Blend in Cream/Serum

Regarding your question about using a powder blend of 99% Acacia Gum and 1% Vitamin C mixed into a cream or serum before application, while physically possible, this method has several potential drawbacks:

• Mixing and Texture: Acacia Gum is a thickener typically used at low concentrations (0.1-5%). Using it as 99% of your powder blend could significantly alter the texture and consistency of your cream or serum, potentially making it too thick or lumpy. Achieving a smooth, evenly dispersed mixture just before application can be difficult, leading to a gritty texture and uneven distribution of the Vitamin C.
• Vitamin C Stability: Standard powder Vitamin C (L-ascorbic acid) is highly unstable when exposed to water and air. While mixing just before application reduces exposure time, some degradation can still occur. For better stability and efficacy, it's generally recommended to use stable forms of Vitamin C or incorporate it into a properly formulated product.

Using a 99% Acacia Gum base with 1% Vitamin C powder mixed into a finished product is not a standard or recommended method for optimal results, stability, or user experience.

Recommendation:

It is generally more effective and stable to use Vitamin C in a properly formulated serum or cream, or to use more stable derivatives of Vitamin C that are designed to be incorporated into formulations. If you wish to use a powder form, consider using a stable Vitamin C powder product specifically designed for mixing, or formulate a simple serum base where the Vitamin C can be properly dissolved and stabilized.
