Steps for Creating a Comparable Formulation Using Ceteareth-25 and Ceteareth-6 (and) Stearyl Alcohol

Ceteareth-25 (also known as Paste Maker) and Ceteareth-6 (and) Stearyl Alcohol are O/W (oil-in-water) emulsifiers that help water and oil combine effectively into a uniform texture. They also contribute to the texture and stability of the formula. The general steps for formulation are as follows:

1. Prepare the Water Phase: Combine all water-based ingredients, including water-soluble substances, and potentially add Ceteareth-25 to the water phase at this stage (Ceteareth-25 is soluble in both water and oil). Then, heat the water phase.
2. Prepare the Oil Phase: Combine all oil-based ingredients, including oils, butters, oil-soluble substances, and add Ceteareth-6 (and) Stearyl Alcohol to the oil phase (Ceteareth-6 (and) Stearyl Alcohol should be mixed in the oil phase). Ceteareth-25 can also be added to the oil phase here. Then, heat the oil phase to a temperature similar to the water phase (generally around 70-80°C, depending on the melting points of the ingredients used).
3. Combine Phases: Once both the water and oil phases are heated, slowly pour the oil phase into the water phase (or vice versa, depending on the technique and primary emulsifier type) while stirring or using a homogenizer to help the emulsion form.
4. Cool Down: Continue stirring or homogenizing as the emulsion gradually cools down to room temperature. Continuous stirring during the cooling phase helps create a smooth and stable cream texture.
5. Add Heat-Sensitive Ingredients: When the temperature of the emulsion drops below 40-45°C (or according to specific ingredient recommendations), add other heat-sensitive ingredients such as preservatives, fragrances, or certain heat-sensitive extracts.
6. Adjust pH (if necessary): Check and adjust the pH of the formula to be within the appropriate range for the product.

• Usage Rates:
  • Ceteareth-25: 0.5-30%
  • Ceteareth-6 (and) Stearyl Alcohol: 2-10%

Using Ceteareth-25 together with Ceteareth-6 (and) Stearyl Alcohol helps enhance the performance in creating a thick, weighty, and highly stable cream texture.
