Rapid Brightening Body Gel Formulation (100g)

Here is a proposed formulation for a rapid skin brightening body gel, along with standard usage percentages and mixing instructions for a 100g batch, based on the ingredients you provided.

Please note that combining this many potent active ingredients, especially at higher concentrations for rapid results, increases the potential for skin irritation. It is highly recommended to perform a patch test on a small area of skin before applying the product to the entire body.

Also, you included "Satin Cream Maker" (ID 247), which is an emulsifier typically used for creams, not gels. I have excluded it from this gel formulation. You also listed "Papaya Enzyme" (Papain) (ID 1036). While Papain is an exfoliant, it requires a pH of 5.5-7.0 for optimal activity and is sensitive to heat. Many of the other brightening ingredients you selected, such as Vitamin C and AHA, are most effective and stable at a lower pH (3.5-4.0). Including Papain in this formula would require a pH that compromises the efficacy of the other key brightening actives. Therefore, I have excluded Papain from this formulation to maintain the effectiveness of the other ingredients.

Ingredients:

• Water: q.s. to 100% (approximately 25.8%)
• Disodium EDTA: 0.2%
• Hydroxyethyl Cellulose (HEC): 1.5% (Adjust based on desired gel thickness)
• Butylene Glycol: 7%
• Propylene Glycol: 7%
• Ceramide Complex: 1%
• PEG-40 Hydrogenated Castor Oil: 3% (Adjust based on oil-soluble ingredients)
• Vitamin A Palmitate: 1.0%
• Vitamin E (Tocopheryl Acetate): 0.5%
• Kojic Acid Dipalmitate: 3%
• Tranexamic Acid: 3%
• Vitamin C (L-ascorbic acid) (Ultra-Fine): 15%
• Glucobright (Acetyl Glucosamine): 4%
• Encapsulated Salicylic Acid: 5%
• Natural Moisturizing Amino Acids: 5%
• Zinc PCA: 1.0%
• Alpha Arbutin: 2%
• Glutathione: 3%
• Sodium Lactate Plus: 5%
• Albumin: 1.0%
• Condi-B5: 1.0%
• Reservoir-Tech: 3%
• Phenoxyethanol: 1.0%
• Caprylyl Glycol: 1.0%
• Citric Acid: as needed (for pH adjustment)

Mixing Instructions:

1. Water Phase: In a beaker, combine the calculated amount of Water and Disodium EDTA. Heat this mixture to approximately 70°C. Slowly add Hydroxyethyl Cellulose (HEC) while blending or stirring continuously until a smooth gel is formed and the HEC is fully dissolved. Once dissolved, remove from heat and begin cooling.
2. Glycol Phase: In a separate container, mix Butylene Glycol and Propylene Glycol. Disperse the Ceramide Complex powder in this glycol mixture. You can warm this phase gently (below 80°C) while stirring to help the Ceramide Complex disperse more easily, then cool to below 40°C.
3. Solubilized Oil Phase: In a third container, combine PEG-40 Hydrogenated Castor Oil. Add Vitamin A Palmitate, Vitamin E, and Kojic Acid Dipalmitate. Heat this mixture gently (below 80°C) while stirring until the powders are fully dissolved and the mixture is clear. Cool to below 40°C.
4. Combine Phases: Once the Water Phase (gel), Glycol Phase, and Solubilized Oil Phase have all cooled to below 40°C, slowly add the Glycol/Ceramide mixture and the Solubilized Oil mixture to the Water Phase while stirring continuously.
5. Add Water-Soluble Actives: To the combined mixture (which should be below 40°C), add Tranexamic Acid, Vitamin C (L-ascorbic acid), Glucobright, Encapsulated Salicylic Acid, Natural Moisturizing Amino Acids, Zinc PCA, Alpha Arbutin, Glutathione, Sodium Lactate Plus, Albumin, Condi-B5, and Reservoir-Tech. Stir thoroughly until all powders are completely dissolved and the mixture is homogeneous.
6. Add Preservatives: Add Phenoxyethanol and Caprylyl Glycol to the mixture and stir to combine.
7. pH Adjustment: Prepare a dilute solution of Citric Acid powder in a small amount of water. Add this Citric Acid solution dropwise to your gel mixture while stirring and measuring the pH. Continue adding until the pH is in the range of 3.5 to 4.0. This pH range is crucial for the efficacy and stability of Vitamin C and AHA, but be aware it may increase the potential for irritation with the high concentration of actives.
8. Final Mix: Stir the gel thoroughly to ensure all ingredients are evenly distributed. Add any remaining water to reach the final target weight of 100g and mix again.

Store the finished gel in an opaque container away from light and heat to help maintain the stability of the light-sensitive ingredients like Vitamin A and Vitamin C.
