Eyebrow Tint Gel Formulation (1kg Batch)

Based on the ingredients you have purchased, here is a suggested formulation for a 1kg batch of eyebrow tint gel.

Please note that based on the quantities you have, the concentration of the active tinting ingredients (DHA and EasyTan) and Reservoir-Tech in a 1kg batch will be lower than the typically recommended usage rates for optimal intensity and effect duration.

Here is the formulation using the full amounts of the active ingredients you have for a 1kg batch:

• Aloe Vera Gel (Heavy): 970 grams
• Dihydroxyacetone (DHA): 20 grams
• EasyTan (Erythrulose): 5 grams
• Reservoir-Tech: 5 grams

Total: 1000 grams (1kg)

Mixing Instructions:

1. Measure out 970 grams of the Aloe Vera Gel (Heavy) base into a clean container. Ensure the gel is at room temperature.
2. Add the 20 grams of Dihydroxyacetone (DHA) powder to the Aloe Vera Gel base. Stir for 3-5 minutes until the powder is dispersed. Let the mixture sit for 15-30 minutes to allow the powder to dissolve, then stir again until fully dissolved with no particles visible.
3. Add the 5 grams of EasyTan and 5 grams of Reservoir-Tech to the mixture. Stir for 1-3 minutes until all liquid ingredients are fully incorporated and the gel is homogeneous.
4. Ensure the temperature of the mixture does not exceed 40°C during mixing, as high temperatures can degrade DHA and EasyTan.
5. Check the pH of the final product. The optimal pH for DHA stability is around 4.0, and EasyTan is most stable between 2.5-3.5, but stable up to 5.0. Aim for a pH between 3.0-5.5 for best stability and performance of both tinting agents. You may need to adjust the pH if necessary using a suitable cosmetic-grade pH adjuster.

This formulation utilizes all of the active ingredients you have to create a 1kg product. Keep in mind that the tinting effect might be lighter or less long-lasting compared to formulas using higher concentrations of DHA and EasyTan within their recommended ranges.
