Coast Biologicals Limited concentrates its effort into producing oils from New Zealand native plants, particularly those that have antimicrobial activity.

Complete oils and oil fractions are produced to enhance activity and to alter the perfume levels.

Mixtures of oil fractions have recently been developed to produce wide spectrum, high potency, low toxicity, antimicrobial oils.
