Acne Face Cream Recipe

Batch size: 100 g

Ingredients

Distilled water – 82 g

Glycerine – 3 g

Emulsifying wax NF – 5 g

Jojoba oil – 5 g

Niacinamide – 4 g

Euxyl PE 9010 preservative – 1 g

Citric acid solution – as needed to lower pH

Sodium hydroxide solution – as needed to raise pH

Method

1\. Sanitise all utensils, equipment and containers before starting

2\. Mix the glycerine with the distilled water, reserving a small amount of water to dissolve the niacinamide

3\. In a separate heat-resistant beaker, combine the emulsifying wax and jojoba oil

4\. Heat both phases separately to approximately 70–75°C until the emulsifying wax has melted completely

5\. Slowly combine the oil phase with the water phase, mixing until a uniform cream forms

6\. Continue stirring gently while the cream cools

7\. Dissolve the niacinamide in the reserved distilled water and add it during cool-down, following the supplier’s temperature guidance

8\. Add Euxyl PE 9010 according to the manufacturer’s instructions

9\. Measure the pH using a calibrated pH meter

pH Adjustment Suggestions

Target pH: Approximately 5.5, subject to the specifications of your ingredients and preservative

To lower pH

Prepare a 10 g citric acid solution by dissolving 1 g citric acid in 9 g distilled water. Add a few drops at a time, mix thoroughly and remeasure the pH

To raise pH

Prepare a 10 g sodium hydroxide solution by carefully adding 1 g sodium hydroxide to 9 g distilled water. Always add sodium hydroxide to water, never water to solid sodium hydroxide. Wear suitable protective equipment because sodium hydroxide is corrosive. Add a few drops at a time, mix thoroughly and remeasure

Do not add a predetermined amount of either solution. The amount required depends on the measured pH of your batch

Important Notes

Include the water used for pH-adjusting solutions in the original water allowance to maintain a final batch weight of 100 g

Use distilled water and sanitised equipment

Check the preservative manufacturer’s recommended use level and pH compatibility

Conduct stability and preservative efficacy testing before selling the cream
