Abstract
Surfactant blends that generate a stable spherical foam are disclosed. The surfactant blends contain a nonionic surfactant or an amphoteric surfactant as the principal foaming agent, and a sufficient amount of an acylate lactylate to enhance foam volume and provide a foam that remains in a spherical form for up to about forty minutes. A method of generating a long-lasting foam also is disclosed.
