Reducing Slipperiness in Facial Cleanser with Lauryl Glucoside
Question
How can the slipperiness of a facial cleanser formulation containing `Cocamidopropyl Betaine` and `Lauryl Glucoside` be reduced, without changing the amounts of these two ingredients or adding other surfactants?
Answer
Based on the previous discussion and the information provided by the staff, the slipperiness you are experiencing is a characteristic of Lauryl Glucoside.
Under the constraints you've set (not changing the amounts of Cocamidopropyl Betaine and Lauryl Glucoside, and not using other surfactants), there is no substance that can be added to specifically reduce this slipperiness.
While adjusting the pH to a higher level (around 8-9) was mentioned as a way to potentially reduce slipperiness, this is generally not recommended for facial skin due to the potential negative impact of high alkalinity.
Therefore, according to the staff's response, if you need to reduce the slipperiness, you would need to consider using different surfactants instead of Lauryl Glucoside, which contradicts your constraint.
