Safety and Handling Precautions
Enzyme preparations are proteins, which may induce sensitization and cause allergic type reactions in susceptible individuals. Prolonged contact may cause minor irritation for skin, eyes or nasal mucosa, so any direct contiguity with human body should be avoided. If irritation or allergic response for skin or eyes develops, consult a doctor.
