Selecting Surfactants for Cleansing Water: Poloxamer vs. PEG-6 Caprylic/Capric Glycerides

Based on the staff's response:

1. Can Poloxamer 407 be used as the main ingredient in cleansing water? If so, at what percentage?

   • Poloxamer 184 is more suitable for use in cleansing water to help remove makeup than Poloxamer 407.
   • Poloxamer 407 is more suitable for solubilizing oil into water in clear formulas with low oil content, such as mouthwash, and is commonly used to dissolve essential oils. The staff did not provide a specific percentage for Poloxamer 407 in cleansing water, suggesting it's not the primary choice for this application.

2. Between Makeup wash (PEG-6 Caprylic/Capric Glycerides), Poloxamer 184, and Poloxamer 407, which one is best for removing makeup?

   • Both Makeup wash (PEG-6 Caprylic/Capric Glycerides) and Poloxamer 184 are suitable for use in cleansing water formulas.
   • Poloxamer 407 is less suitable for makeup removal compared to Poloxamer 184.
   • The staff does not have comparative research results to determine which between Makeup wash and Poloxamer 184 is definitively the best.
   • The overall effectiveness of a cleansing water formula also depends on other components that help dissolve makeup, such as Butylene Glycol.

3. If multiple ingredients are mixed, such as Makeup wash 4% and Poloxamer 184 3%, will it increase makeup removal effectiveness?

   • Yes, using a higher proportion or a greater variety of surfactants in a formula can increase effectiveness.
   • However, you should consider the necessary level of effectiveness. If makeup is already effectively removed, there is no need to increase the proportion or variety of surfactants, as this increases the formula's cost and may lead to a sticky feeling on the skin after use.
