Comparison of Polyhydroxystearic Acid: High vs Low Viscosity Grades

Asked by: paweephat.junsong On: April 19, 2021 Product Type: Cosmetics

Question

Regarding the two types of Polyhydroxystearic acid available on the website, High and Low Viscosity, I would like to inquire about the following information:

1. Do the High and Low Viscosity grades have different % breakdown of chemical ingredients? If so, which chemical ingredients are different, and what are their percentages? Please provide information or supporting documents.
2. Is any additional solvent added to the Low Viscosity Grade to make the chemical liquid? If yes, which solvent is used?
3. Please provide information on the viscosity of both the High and Low Viscosity grades.

I would appreciate this additional information to help me decide which product to purchase. Thank you.

Answer

Polyhydroxystearic acid High vs Low Viscosity

  • % Breakdown of Ingredients: The product description does not provide a detailed percentage breakdown of the chemical ingredients or specify if there are different chemical components between the High and Low Viscosity grades. The INCI name listed for the product is Polyhydroxystearic acid, indicating this is the primary component.
  • Solvent in Low Viscosity Grade: The description does not mention the addition of any solvent to the Low Viscosity grade. It is described as having a "Liquid oil texture".
  • Viscosity Information: The product description provides qualitative descriptions of the viscosity for each grade:
    • High Viscosity: Described as having a "high viscosity Cream texture".
    • Low Viscosity: Described as having a "low viscosity Liquid oil texture".

      Specific numerical viscosity values (e.g., in cP) are not provided in the description.

In summary, while the product description confirms the existence of High and Low Viscosity grades with different textures (cream vs liquid oil), it does not provide specific details on chemical composition differences, the presence of solvents, or numerical viscosity values.
