Surfactant

But the project's principal investigator, at the materials science center of Trinity College in Dublin, says it can be done by mixing graphite with water and a surfactant, a form of soap, in an ordinary kitchen blender.

Dr. Khorana added that this is especially true of cleansers that feature surfactants like sodium lauryl sulfate, as this class of ingredients can cause “dryness, irritation and eczema.”

It is conceivable that impairment of surfactant proteins is due to rheological and immunodefensive disorders of testis and epididymis or prostate.
