Synergic Associations

“The Synergism that comes from the interaction of opposite charges surface agents is sensitively greater
than that coming from the interaction of equal charges surface agents or ionic and nonionic surfactants.”

Cleaning Performance Test

Methodology
Linoleum plaques (three for each product)
Cleaning Performance Test (HSC) Reflectance A

 Objective: Soil application (0.5 g per plaque)

-To evaluate the washing performance

of a hard surface cleaner.
Plaques stand overnight at RT

Reflectance B
 The Test:

-Gardner equipment. Cleaning process of plaques

5 mL of product on the plaque
-Response is given by the equation at 5 mL of product on the sponge

the end of the procedure.

Methodology
 The test for the anti-microbial activity of disinfectants is performed with 60
cylinders for each bacteria.
 The disinfectant should be able to kill bacteria attached on 59 stainless
steel cylinders (for each bacteria) in the contact time of 10 minutes for a
95% confidence limit.
