No classification data on carcinogenic properties of this material is available from EPA, IARC, NTP, OSHA or ACGIH.
ADI: 0.01 mg/kg b.w./day [Rat, SF=1000]
Classification:
Toxicity class WHO (a.i.): II (Moderately hazardous)
US EPA Classification (formulation): III (Caution - Slightly toxic)
EC Risk Classification: Xn - Harmful: R22; Xi - Irritant: R36/37/38
ECOTOXICOLOGY
Effect on birds: low toxicity to birds, acute oral LD50 for Japanese quail is >2000 a.i.mg/kg. Effect on fish: moderate toxicity to fish, acute 96 hour LC50 for Rainbow trout is 2.39 a.i.mg/L. Effect on aquatic invertebrates: moderate toxicity to aquatic invertebrates, acute 48 hour EC50 for Daphnia magna is >4.52 a.i.mg/L. Effect on algae, low toxicity to algae, acute 72 hour EC50 for Desmodesmus subspicatus is 29 a.i.mg/L. Effect on honeybees: low toxicity to honeybees, contact acute 48 hour LD50 is >200 a.i.μg/bee. Effect on earthworms: low toxicity to earthworms (as formulation, product conc 4.5% a.s.), acute 14 day LC50 is >1000 mg/kg.
ENVIRONMENTAL FATE
β-Naphthoxyacetic Acid's production may result in its release to the environment through various waste streams; its use as a plant growth regulator will result in its direct release to the environment. If released to air, a vapor pressure of 2.89×10-3 mPa at 25 deg C indicates β-Naphthoxyacetic Acid will exist solely in the particulate phase in the atmosphere. Particulate-phase β-Naphthoxyacetic Acid will be removed from the atmosphere by wet or dry deposition. If released to soil, β-Naphthoxyacetic Acid is expected to be mobile based upon an estimated Koc of 72.0. Volatilization from moist soil surfaces is not expected to be an important fate process based upon an estimated Henry's Law constant of 1.06×10-4 Pa m3/mol. β-Naphthoxyacetic Acid is not expected to volatilize from dry soil surfaces based upon its vapor pressure. EU dossier DT50 lab studies range 18.1-100.5 days, DT90 range 10-443 days. If released into water, β-Naphthoxyacetic Acid is expected to adsorb to suspended solids and sediment based upon the estimated Koc. Volatilization from water surfaces is not expected to be an important fate process based upon this compound's estimated Henry's Law constant. LogP < 3 suggests the potential for bio-concentration in aquatic organisms is low.
Usage: β-Naphthoxyacetic acid is a naphthalene-based auxin, absorbed via root and leaf. It can promote fruit set, stimulate fruit erlargement and prevent hollow fruits. It can also stimulate root formation when co-used with rooting agent.
Application: Naphthylacetic acid (BNOA) is a naphthalene plant growth regulator with auxin bioactivity, absorbed by leaves and roots. Can promote fruit, stimulate the fruit to expand, and can overcome the hollow fruit; with the root agent used together, but also to promote plant rooting.Used as a plant growth stimulant, used to improve the pineapple, strawberry, tomato fruit rate and adjust the growth
