    Witco Petro IPSA is an alky naphthalene sulfonic acid. This product may be diluted and used in the acid form, or it may be neutralized prior to dilution and use. Typically, ammonia or an inexpensive amine is utilized to neutralize Petro IPSA. Witco Petro IPSA works by effectively neutralizing the strength of the natural emulsifying agent, allowing the finely dispersed water droplets to coalesce. As the tiny water droplets merge into progressively large and heavier drops, the water settles and the oil rapidly rises to the top. The result is a sharp, well-defined oil/water interface and bright, clean and marketable oil.
