noun / verb
suds
SUDZ/sʌdz/
Bubbles forming a foam in soapy water.
Suds cover the washbasin's water beside the wet bar of soap.

Etymology
Suds first appears meaning dregs, leavings, or muck, and later means soapy water. Its deeper origin is uncertain, so the evidence does not securely explain the connection between those earlier meanings and soap foam.
In context
by putting the water first and then the product at the end you're not creating as much bubbles or suds so it won't overflow
