Is Ammonium Lauryl Sulfate a 'sulfate' that should be avoided?
Ammonium Lauryl Sulfate is indeed a sulfate, a class of cleansing agents. While effective, some individuals with sensitive skin or hair may find it too drying or irritating, leading them to prefer sulfate-free alternatives.
What is the difference between Ammonium Lauryl Sulfate and Sodium Lauryl Sulfate?
Both are anionic surfactants used for cleansing and foaming. Ammonium Lauryl Sulfate is generally considered slightly milder than Sodium Lauryl Sulfate, though both can be irritating depending on concentration and individual sensitivity.
