Revisions incorporate updated particle size distribution data, including propellant-based sprays such as dry shampoos, and expand sample exposure calculations against occupational permissible exposure limits. The document revises inhalation boilerplate to cover pump versus propellant products, emphasizes realistic-use particle sizing, considers TTC approaches and regional deposition tools, addresses interspecies differences, and raises concerns about nanoparticle exposures.","ADMIN  \nInhalation  \nEXPERT PANEL MEETING December 2-3, 2024  \nCommitment & Credibility since 1976  \nMemorandum  \nTo: Expert Panel for Cosmetic Ingredient Safety Members and Liaisons  \nFrom: Jinqiu Zhu, PhD, DABT, ERT, DCST, CIR Toxicologist  \nDate: November 8, 2024  \nSubject: Draft Revised Respiratory Exposure to Cosmetic Ingredients Resource Document  \nEnclosed is an updated draft of the Resource Document – Respiratory Exposure to Cosmetic Ingredients (report_InhalationDocument_ 122024), along with the transcripts from previous Panel discussions (transcripts_InhalationDocument_ 122024) . The Panel last approved the Document at the December 2021 meeting. Subsequent revisions were made at the December 2023 meeting to incorporate additional particle size data in some types of propellant-based sprays, such as dry shampoos in powdered galenic formulations. These findings highlighted the necessity to modify the inhalation boilerplate (BP) to more accurately reflect the Panel's perspective on the associated inhalation risks.  \nAt the September 2024 meeting, the Panel reviewed a Strategy Memo concerning updates to the Inhalation BP and discussed the required context for its application in the report. The Panel then requested updates to both the inhalation BP and the Respiratory Exposure Resource Document, aiming to clarify the rationale behind the changes and to better represent the Panel’s understanding of exposure to airborne particles/droplets from various cosmetic sprays, along with the associated health risks.  \nThe updated Document includes additional sample exposure calculations for dry shampoo and propellant deodorant, incorporating the latest particle size distribution data and comparing the results with permissible exposure limits in occupational settings. Additionally, the revisions expand on various aspects including measurement under realistic usage scenarios, the potential use of Threshold of Toxicological Concern (TTC) approaches, tools for assessing regional particle deposition, the examination of interspecies differences in predicting human effects, and concerns about nanoparticle exposures.  \nThe inhalation BP has been revised to accommodate different types of spray products (e.g., pump vs. propellant), and highlights the importance of measuring particle size distribution under realistic usage scenarios for accurate exposure estimate and inhalation risk assessment. Importantly, it emphasizes that the Panel would review all pertinent data and, when necessary, request specific exposure and inhalation toxicity data on a case-by-case basis, especially when existing data are absent or insufficient to ensure the safety of ingredients in aerosolized products. For the Panel's review, the modifications ofthe Resource Document and Inhalation BP have been highlighted in yellow.  \nComments provided by the Council on the Inhalation Resource Document (submitted on November 30, 2023) and on the Strategy Memo for the Inhalation BP Revision (submitted on September 24, 2024) have been addressed (identified as Councilcomment_inhalationDocument_122014 and Councilcomment_inhalation BP_ 122024, respectively) . On October 30, 2018, the CIR Science and Support Committee (CIR SSC) submitted comments proposing a tiered approach for evaluating inhalation safety. The comments also include particle size data for aerosol hair sprays and aerosol deodorants/antiperspirants, which were measured by laser diffraction from companies that market these types of products. These comments are also included in this package for the Panel’s consideration (identified as CIRSSCcomment_2018_inhalationDocument_ 122024) .  \nThe Panel should review the revised Document to assess the relevance and applicability of the inhalation BP, and update it as necessary to align with their understanding of exposure to airborne particles/droplets from the use of spray products, and issue the document to replace the currently posted version.
