# SUPPLEMENTARY INFORMATION:

## I. Background

                    In the                     **Federal Register**                     of October 30, 2014 (79 FR 64603), we published a notification of public meeting and requested comments on certain topics related to the Redbook. The Redbook provides guidance to industry and other stakeholders (                    *e.g.,*                     academia and other regulatory groups) regarding the information used by FDA's Center for Food Safety and Applied Nutrition to evaluate the safety of food additives and color additives. The Redbook is intended to help interested parties understand FDA's expectations regarding:                
    - Determining the human exposure that will occur from the use of the ingredient in foods;
    - Determining which toxicity studies are appropriate;
    - Designing, conducting, and reporting the results of toxicity studies; and
    - Submitting the information to FDA as part of a safety assessment.

Comments on the Redbook will inform our future efforts on what should be included, changed, or even excluded from the updated Redbook. We are interested in expanding the scope of the Redbook to emphasize the principles of safety and risk assessment that are shared across different regulatory contexts for foods and cosmetics, while still providing specific guidance for applying these principles in particular contexts such as the requirements for premarket safety submissions or for risk assessments conducted on foods and cosmetics already on the market.

We have received a request for a 90-day extension of the comment period for the notification of public meeting and request for comments. The request conveyed-concern that the current 90-day comment period (which would otherwise expire on February 9, 2015) does not allow sufficient time to develop meaningful or thoughtful responses to the notification of public meeting and request for comments.

We have considered the request and are extending the comment period for 90 days, until May 10, 2015. We believe that a 90-day extension allows adequate time for interested persons to submit comments without significantly delaying further action on these important issues.

## II. Request for Comments

                    Interested persons may submit either electronic comments regarding this document to                     *http://www.regulations.gov*                     or written comments to the Division of Dockets Management (see                     **ADDRESSES**                    ). It is only necessary to send one set of comments. Identify comments with the docket number found in brackets in the heading of this document. Received comments may be seen in the Division of Dockets Management between 9 a.m. and 4 p.m., Monday through Friday, and will be posted to the docket at                     *http://www.regulations.gov.*

Dated: January 27, 2015.

Associate Commissioner for Policy.
