About EfferCept

EFFECTIVE Quickly kills a broad spectrum of mastitis-causing organisms on contact. Near neutral pH of 6.7 is non-corrosive, non-caustic and non-irritating.
EFFICIENT Fast-acting effervescent tablets dissolve in hard or soft potable water on farm. Precise measurement designed for any herd size.
ECONOMICAL Spend less and gain more. EfferCept® helps to lower somatic cell count and to reduce the high cost of mastitis. No mixing or hauling of heavy barrels or totes.

EfferCept Sanitizing Teat Dip when dissolved in water combines the mild, non-irritating, yet powerful killing of EfferCept with cleaning and conditioning to soothe and protect skin, teats, and udders. EfferCept uses hypochlorous acid to penetrate cell walls and deactivate the detrimental organism’s primary energy-producing function. Other disinfectants apply an extra-cellular oxidation-reduction reaction that burns or erodes the cell wall.




Mastitis, or inflammation of the mammary gland, is widely considered the single-most profit robbing disease in the U.S. dairy industry. It is critical for preventative measures to be as effective as possible. When used as a pre / post milking teat dip, foam, scrub, or spray, EfferCept controls a broad spectrum of mastitis-causing organisms.

EfferCept stands apart from other teat dip products like iodine by maintaining the active ingredient of EfferCept is sodium dichloroisocyanurate (NaDCC), in effervescent tablet form for simplified preparation. While the active ingredient in EfferCept is a member of the chlorine family, it differs from other chlorine-based treatments that operate at a pH favoring the prevalence of the OCl¯ ion. The product is pH-buffered—formulated specifically to prevent major shifts in pH—so that it exhibits a near-neutral pH of 6.3–6.7 regardless of the concentration level. With a pH comparable to water, EfferCept is set apart from bleach and other chlorine products in its odorless smell and absence of corrosive properties, maintaining the integrity of any equipment or bedding it encounters as it sanitizes.

Hypochlorous acid (HOCl) provides exceptional killing power with virtually no irritation. The HOCl molecule is key to the product’s demonstrated performance against a wide range of harmful organisms. This molecule bears no positive or negative charge and, unlike the negatively charged OCl¯ ions produced by chlorous acid/chlorine dioxide treatments or OI¯ ions produced by iodine treatments, it is not repelled by the negatively charged bacterial cell wall. It penetrates the cell wall to deactivate the cell’s primary energy-producing source, resulting in rapid cell death.

The molecule easily penetrates microorganisms but does not easily penetrate animal and human skin cells. The HOCl contained in the product formulation reacts with soil and fat substances, converting them to soluble salts that rinse away.

1. The prepared solution is non-caustic with minimal irritation to skin and animal tissue.

2. This neutral pH is created by a high concentration (95%) of hypochlorous acid, HOCl, and a minimum concentration (5%) of the hypochlorite ion, OCl¯. Both HOCl and OCl¯ are relatively strong disinfectants. However, HOCl, as in EfferCept, offers several efficacy advantages:
• Increased control of mastitis-causing organisms
• Continued performance in the presence of organic matter
• Fast kill

In a university study the active ingredient in EfferCept, at half the concentration of Clorox® bleach, demonstrated greater germicidal activity than bleach or 1% Iodine.1

Independent laboratory results show EfferCept kills 99.99% of E. coli and Staph. aureus within 15 seconds of exposure time – half the industry standard of 30 seconds.
