Recommendations for Improving Liquid Facial Soap

The issues of residual slipperiness on the skin after rinsing and low foam are often caused by selecting surfactants that are not suitable for the desired properties of a facial cleansing product. Some surfactants may provide a soft, slippery feel during washing but can leave a slippery residue after rinsing, while others may produce low foam.

The approach to solving this is to consider changing or combining surfactants that have good foaming properties and rinse off easily without leaving a sticky or slippery feeling on the skin.

Recommended Surfactants to Reduce Slipperiness and Increase Foam:

• Isethionate Group: This group of surfactants is mild, provides very good foam, and typically leaves a clean feel on the skin after rinsing without slipperiness. An example is IseFoam™ (Sodium Lauroyl Methyl Isethionate).
• Sarcosinate Group: Another mild group that provides good foam and a clean feel. An example is Cond-Foam™ (Sodium Lauroyl Sarcosinate) (available in liquid and powder forms).
• Glutamate Group: Amino acid-based surfactants that are very mild, provide good foam, and offer a soft feel that rinses off easily. An example is AminoWash™ (Sodium Lauroyl Glutamate).
• Taurate Group: Provides a soft, creamy foam and is mild. An example is Creamy Foamer™ (Sodium Methyl Cocoyl Taurate).

Additionally, you might consider using other surfactant groups that help boost foam and improve texture, such as SulFoam™ (Disodium Laureth Sulfosuccinate) or Powderly Foam™ (Potassium Laureth Phosphate), or ready-made bases designed for good foam and mildness, such as Apple-Foam™.

When adjusting the formula, the overall composition and the proportion of each surfactant used should be considered to achieve the desired properties in terms of foam, feel during washing, and feel after rinsing. If you can provide your current formula details, further recommendations for adjustment can be given.
