Consumer Habits and Practices for Formulated Cleaning Products and Personal Care Products

Presented By:

Dr. Paul C. DeLeo Senior Director, Environmental Safety

21st Annual Meeting of the International Society of Exposure Science Baltimore, Maryland

October 25, 2011

Symposium on:

Exploring Global Data Resources for Consumer Exposure Assessment

1

About ACI

• ACI is a 117-member trade association representing the $30 billion US cleaning products industry

• ACI has studied product ingredient safety for 50 years

• ACI sponsored nearly 300 of 2,700 HPV chemicals in the EPA and OECD programs over the last decade

• ACI provided data beyond-SIDS including exposure and screening-level risk assessments of its ingredients

2

Information Needs for Exposure Assessment of Formulated Consumer Products

• What ingredients are in products? • What are the exposure models for products? • What are the exposure factors for products? • What is the ingredient concentration? • Is there one place where I can find all of this

information?

3

What ingredients are in products? • Mandatory ingredient reporting

– Cosmetic labeling (except fragrances, dyes, preservatives) • Fragrance Industry published a list of fragrance ingredients used in

consumer goods by their customers worldwide in 2010

– Cleaning product labeling in Europe

• Voluntary ingredient reporting for cleaning products – N. America Ingredient Communication (ACI/CSPA/CCSPA) (http://www.cleaninginstitute.org/ingredientcentral/) – Australia “What’s In It?” campaign (ACCORD)

4

What are the exposure models for products?

Product exposure scenarios broken down by: • Route of exposure (dermal, oral, respiratory) • Direct/Indirect exposure • Activity/Use • Regional approaches (North America, Europe,

Other)

5

Sample Exposure Models Exposure Route PE Scenario PE Model Parameters

Dermal: Indirect Exposure after activity/use: Laundry detergents: wearing clothing Fabric conditioners: wearing clothing

North American (NA) approach:

A × PR × PT × CF × DA BW

where, PR = 1% based on SDA data

European Union (EU) approach:

A × PR × PT × CF × DA BW

where

PR = (PD × FD) / W) × CA

and

PD = Sw / Tw

A: amount used (g/day) PR: percent retained on clothing (%) PT: % transferred from clothing to skin CF: conversion factor (1,000 mg/g) DA: dermal absorption (100%) BW: female body weight (60 kg) PD: percent deposition (%) FD: fabric density (mg/cm2) W: total wash weight (mg) CA: body surface contact area (cm2) Sw: Mass of water after spin cycle (kg) Tw: Mass of water per spin cycle (kg)

Dermal: Direct Exposure during activity/use of: Laundry detergent: hand-washing clothes Laundry detergent: laundry pretreatment Dish detergent: hand-washing dishes Dish detergent: washing hands Dilutable hard surface cleaners Nondilutable hard surface cleaners Dilutable all-purpose cleaners Nondilutable all-purpose cleaners

NA and EU approach:

FQ × CA × PC × FT × CF × TF × DA BW

FQ: frequency of use (use/day) CA: body surface contact area (cm2) PC: product concentration (g/cm3) FT: film thickness on skin (cm) CF: conversion factor (1,000 mg/g) TF: time scaling factor (unitless) DA: dermal absorption (100%) BW: female body weight (60 kg)

6

What are the exposure factors for products?

Exposure factors (habits and practices) for formulated consumer products: • Frequency of product use • Amount of product per use (dosing) • Duration of use (time to rinse-off)

7

Data Sources • Regulatory authorities (e.g., EPA Exposure Factors

Handbook, EU Technical Guidance Document) • Submissions to regulatory authorities (e.g., AISE-

CEFIC HERA, AIHC exposure initiative assessments) • Published literature • Survey data collected by industry associations (i.e.,

CTFA/PCPC, COLIPA, AISE, SDA/ACI) • Member company data

8

Exposure Factor Data Sources

• Cleaning product habits and practices – For laundry, dishwashing & hard surface cleaners

• North America: SDA/ACI (Sanderson et al., 2006) • Europe: AISE/CEFIC HERA Guidance Document (2005)

• Personal care product habits and practices – For 12 product types covering 95% of exposure)

• U.S.: CTFA/PCPC (Loretz et al., 2005, 2006, 2008) • Europe (Hall et al., 2007, 2011)

9

What is the ingredient concentration?

SDA 2001 Member Survey • Chemical production/importation volume • Chemical use by product category (e.g., liquid

laundry detergent) • Chemical releases to the environment • Conditions under which potential worker exposures

are mitigated • Concentration in formulated products

10

SDA Member Survey Results • Minimum/maximum ingredient concentrations • Major chemical categories: Aliphatic acids, Aliphatic

alcohols, Alkyl sulfates, Amine oxides, Hydrotropes, LAS • Five product categories

– Laundry: 9 product types – Dishwashing: 3 product types – General Cleaning: 7 product types – Personal Care: 15 product types – Cosmetics: 4 product types

• North America, Europe and Japan

11

One-stop Shopping

• Exposure data for formulated consumer products

• Risk screening methodology • Case studies: peer-reviewed

journal articles • Ingredient concentration data • Available on ACI Science

website (aciscience.org)

12

Summary

• Data are readily available for what ingredients are in cleaning product from manufacturers (http://www.cleaninginstitute.org/ingredientcentral/)

• Info on exposure models, exposure factors and (some) ingredient concentrations for formulated consumer products are available via ACIScience.org

• Ingredient concentration data are often proprietary so some educated estimation may be necessary
