摘要：
A surfactant product includes a first effervescent material and a second effervescent material. Each effervescent material is capable of effervescence on contact with water, wherein the rate of effervescence of the first effervescent material is greater than the rate of effervescence of the second effervescent material. The first and second effervescent materials are distinct from each other and at least one of the effervescent materials envelops the other of the effervescent materials.
