Body Whitening Formula Review: High B3, Gluco Bright, Vitamin C Compatibility & Texture

Question

I want to use Safe B3 10% in a body whitening formula with the following ingredients: Safe B3 10%, Z-White 1%, Gluco Bright 4-8%, Double hya 10%, Vitamin C SAP 3% (if usable), DMI 3%, Active Protec 1%, Satin Cream Maker 1%, Odor Kill 1%. 1. What percentage of Gluco Bright should I use (technical notes recommend 4-8% with B3 5%)? 2. Are there any Vitamin C derivatives that can be mixed in the same formula as Safe B3 without losing the efficacy of both? I've read it might be SAP but am unsure, so I'd like to ask the team directly. 3. Will the formula feel sticky when used?

Formula Review and Recommendations

Thank you for sharing your body whitening formula. Here are the answers to your questions based on the ingredients you plan to use:

1. Gluco Bright Percentage

Based on the information for Gluco Bright, the recommended usage rate is 1-8%. While the technical notes suggest 4% when combined with 2-4% Niacinamide, using Gluco Bright within the 4-8% range is still suitable for your formula containing 10% Safe B3 to work synergistically for whitening.

2. Vitamin C Compatibility with Safe B3

You are asking about adding Vitamin C SAP to your formula with Safe B3. Safe B3 (Niacinamide) is most effective and stable in a pH range of 4.0-7.0. Vitamin C SAP (Sodium Ascorbyl Phosphate), on the other hand, requires a more alkaline pH of 7-9 for optimal stability.

Combining ingredients that require significantly different pH ranges for stability and effectiveness in the same formula can lead to reduced performance of one or both ingredients. Therefore, it is generally not recommended to combine Vitamin C SAP with Safe B3 in the same formula if you aim for maximum efficacy of both.

There are other forms of Vitamin C available, but their compatibility with Safe B3 would also depend on their required pH for stability.

3. Formula Texture

Your formula contains several water-soluble ingredients at relatively high concentrations, such as Safe B3 at 10% and Double Hyaluron Liquid at 10% (which provides 0.5% actual Hyaluronic Acid). High concentrations of ingredients like Niacinamide and Hyaluronic Acid can sometimes contribute to a slightly sticky or tacky feel on the skin.

While Satin Cream Maker is included to create a cream texture and should help improve the overall feel, the high active load from Safe B3 and Double Hyaluron Liquid might still result in some residual tackiness upon application, depending on the final formulation and individual skin perception.
