Question

Answer

Achieving Clarity with PEG-150 Distearate in Shampoo Formulations

When using PEG-150 Distearate (Pellets) to thicken your shampoo, it is crucial to ensure proper dissolution to achieve a clear product. While heating to 60-70 degrees Celsius is a good start, here are some additional tips to help prevent cloudiness:

  • Ensure Complete Dissolution: Even at the recommended temperature, PEG-150 Distearate needs sufficient time and thorough stirring to dissolve completely. Continue stirring until the solution is visibly clear and no pellets or undissolved particles remain. Incomplete dissolution is a common cause of cloudiness.
  • Optimal Usage Rate: Our PEG-150 Distearate (Pellets) is typically used at a rate of 1-5%, with 1-3% being recommended for desired viscosity. Using too high a concentration can sometimes lead to cloudiness or difficulty in achieving full clarity. Ensure your concentration is within the recommended range.
  • Order of Addition: It is generally recommended to mix PEG-150 Distearate into the water phase or directly into the detergent base while heating. Once fully dissolved, you can proceed with adding other ingredients.
  • High Detergent Content: PEG-150 Distearate is known to provide clarity in formulas with high detergent content. Ensure your shampoo base has a sufficient amount of primary surfactants.

By carefully following these guidelines, you should be able to achieve a clear and stable shampoo formulation using PEG-150 Distearate (Pellets).
