Formulation Questions Answered

Here are the answers to your questions regarding your cosmetic formulation:

1. Compatibility of Ingredients

Based on the product information, using Pure-Succinic™ at 2% with Plankton Artemia Extract, Marine Plankton (Lifting, Tightening), Palmaria Palmata Extract, Safe-B3™ (Vitamin B3, Niacinamide), Copper PCA, and Disodium EDTA at their recommended percentages should be compatible.

Key considerations for successful formulation:

• pH Range: Ensure the final formulation pH is within the compatible range for all ingredients. A pH between 4.0 and 6.0 appears suitable for most of these ingredients, although some have wider acceptable ranges.
• Mixing Method: Add Disodium EDTA to the water phase first. Most other ingredients can also be added to the water phase.
• Heat Sensitivity: Avoid prolonged or excessive heat during the mixing process, especially for the plankton extracts, Palmaria Palmata Extract, Safe-B3™ (Vitamin B3, Niacinamide), and Copper PCA.

2. Comparing Plankton Extracts

When choosing between Plankton Artemia Extract and Marine Plankton (Lifting, Tightening) as a primary active ingredient for improving skin smoothness, health, and hydration, based on the available descriptions:

• Plankton Artemia Extract focuses on protecting the skin from environmental stress (anti-pollution) and boosting fundamental skin components like collagen and keratin, which contribute to overall skin health, barrier function, and hydration. It also shows effects on cell metabolism and reducing UV damage.
• Marine Plankton (Lifting, Tightening) primarily highlights its immediate and long-term effects on skin lifting, tightening, and reducing the appearance of wrinkles, particularly those on the epidermis.

For benefits related to overall skin health, smoothness, and hydration as a core ingredient, Plankton Artemia Extract appears to offer a broader range of fundamental benefits that support these goals. While Marine Plankton provides visible lifting and tightening, Artemia Extract's impact on cellular health, collagen, and keratin production seems more directly aligned with improving the underlying health and texture of the skin for lasting smoothness and hydration.

3. Preservative in Natural Moisturizing Amino Acids

Regarding the preservative used in Natural Moisturizing Amino Acids, the current product description states that it is preserved by Phenoxyethanol 0.5%. This aligns with the information on the product webpage and indicates that Methylparaben and Propylparaben are not currently used in this product.
