Phenylpropanoids and Aldehydes Group
These substances were identified for action under the Chemicals Management Plan (CMP). The assessment focuses on 12 substances, referred to collectively under the CMP as the Phenylpropanoids and Aldehydes Group, which are a part of the larger Terpenes and Terpenoids Group.

Background
The assessment focuses on 12 substances referred to as the Phenylpropanoids and Aldehydes Group. The human health risk assessment addressed 9 of the 12 substances under 2 subgroups, due to similarities in chemical structure, properties, or toxicity, while the remaining 3 substances were addressed individually. The ecological risks of substances in this group were characterized using the Ecological Risk Classification of Organic Substances (ERC) Approach. These 12 substances are a part of a larger group of 76 substances referred to collectively under the CMP as the Terpenes and Terpenoids Group.
Three of these 76 substances were subsequently determined to be of low concern to both human health and the environment through other approaches. The conclusion for CAS RN 25428-43-7 is provided in the Final Screening Assessment for the Rapid Screening of Substances with Limited General Population Exposure. Conclusions for CAS RNs 29350-73-0 and 68916-97-2 are provided in the Final Screening Assessment of Substances Identified as Being of Low Concern using the Ecological Risk Classification of Organic Substances and the Threshold of Toxicological Concern (TTC)-based Approach for Certain Substances.
Fifteen of these 76 substances (CAS RNs 80-56-8, 1113-21-9, 8000-46-2, 8002-09-3, 8006-64-2, 8007-01-0, 8007-02-1, 8008-31-9, 8008-52-4, 8008-57-9, 8014-19-5, 8015-77-8, 8016-85-1, 8021-28-1 and 9005-90-7) were assessed as a part of the Acyclic, Monocyclic, and Bicyclic Monoterpenes Group.
Sixteen of these 76 substances (CAS RNs 495-62-5, 8001-61-4, 8007-0-7, 17627-44-0, 65113-99-7, 107898-54-4, 87-44-5, 88-84-6, 3691-12-1, 4630-07-3, 68917-29-3, 489-86-1, 639-99-6, 22451-73-6, 489-84-9 and 8006-87-9) were assessed as a part of the Monocyclic and Bicyclic Sesquiterpenes Group.
Decisions on the remaining 30 substances will be communicated in separate risk assessments.
