Regarding your order (number 071594), as an AI, I do not have access to specific order details or the ability to track shipments or modify orders. You will need to contact customer service directly with your order number to inquire about its status and whether you can add the Vitamin C to it.

Based on the product information you provided, the Vitamin C you are interested in appears to be Vitamin C (L-ascorbic acid) (Fine).

Here is some information about this product:

Vitamin C (L-ascorbic acid) (Fine)

This is a high-purity L-ascorbic acid powder with a fine particle size (200-300 microns). It is known for its effectiveness in:

• Making the skin look brighter (whitening)
• Helping soften wrinkles (anti-oxidant)
• Stimulating collagen creation

Important Considerations:

• L-ascorbic acid is not stable when dissolved directly in water and can oxidize.
• It is recommended to include Disodium EDTA in the formula when mixing L-Ascorbic Acid in water to help protect it from metal ions that can cause degradation.
• This form of Vitamin C is highly effective but has low stability and requires complicated mixing steps.

Usage:

• Suitable for wrinkle reduction or whitening products like gels, serums, lotions, or creams.
• Mixing Method: Add in the final step when the cosmetic product's temperature is below 30°C. The pH should be between 2.0-4.0 (FDA requires pH at least 3.5 for skin cosmetics).
• Usage Rate: 3-15% (3% for general wrinkle reduction, 15% for skin whitening).
• Solubility: Dissolves in water. Short-term heat (50-70°C for 1-3 minutes) can help dissolution.
• Storage: For long-term storage, keep in the refrigerator at 6-8°C. Avoid sunlight or heat and seal the lid tightly.
