Stepan UP Program:

Solutions to Help You Step Up to Regulation Challenges

Stepan Company is here to partner with you as you work to remain compliant with 1,4-dioxane legislation through the UP Program.

The UP Program provides comprehensive technical and formulation support to help you decrease or eliminate 1,4-dioxane, whether you switch to a low 1,4-dioxane product, rebalance your formulations, or reformulate completely.

Stepan UP Program

UP

In support of our goals of continuous improvement and product stewardship, Stepan Company is introducing the new Stepan UP Program! The goal of this program is to provide solutions that help you step up to challenges faced when addressing 1,4-dioxane legislation.

Low 1,4-Dioxane Product Checklist Whether you’re making changes to meet 1,4-dioxane legislation or launching a new concept, product development can be complicated and time consuming. We recommend you start by: Reviewing and identifying formulations that may contain residual 1,4-dioxane and are subject to legislation.

Determining where your formulations currently stand in terms of 1,4-dioxane compliance by testing samples according to your established testing protocols.

Developing a plan of action. Based on your results, this could include reformulating or identifying a low-dioxane substitution.

Not sure where to start? Stepan has the knowledge, resources and formulation expertise to help you make decisions and navigate reformulation efforts. Contact us today.

Choosing Alternatives to Ether Sulfates The most common alkyl ether sulfate used in personal care cleansing applications is Sodium Laureth Sulfate, often abbreviated as SLES. Formulators have preferred using SLES due to its mildness, effective viscosity building and foaming quality. Formulators looking to move to an SLES alternative may have questions or concerns regarding the physical and performance changes to their formulations.

Two common alternatives to SLES are Sodium Lauryl Sulfate and Sodium Coco-Sulfate. Both build viscosity similar to SLES and have good flash foam. Learn about the benefits and performance characteristics of these options in Sulfate Alternatives to SLES on page 8.

For formulators that would like to support “sulfate-free” claims, there are many non-SLES, sulfate-free alternatives available in the market. Read about the benefits of Stepan’s Sulfate-Free Alternatives to SLES and how easy it is to formulate comparable to SLES using Stepan Specialty Secondary Surfactants on pages 10-17.

Primary Surfactants for Personal Care Stepan offers a broad range of non-SLES primary surfactants, most of which are sulfate-free. Each chemistry shown below can offer formulation benefits and depending on the composition of the end formulation, has the potential to enable additional marketing claims such as “sulfate-free” or “natural/naturally derived.”

Sulfate-Free Alternative Chemistries Why go sulfate-free?

Sulfate-free surfactants are generally milder to the hair and skin than SLS or SLES, which means that fresh hair color can last longer and skin may feel softer.

Stepan Company is a global leader in providing sulfate-free ingredients for the personal care market.

Are there any downsides to sulfate-free surfactants?

Sulfate-free surfactants are known for being mild, but formulators may find that they have trouble thickening products containing sulfate-free surfactants.

Fortunately, Stepan offers specialty surfactants that provide powerful thickening for sulfate-free systems saving time and headaches for formulators replacing sulfate surfactants. These specialty surfactants —

AMPHOSOL CDB-HP (Cetyl Betaine) and NINOL® CAA (Dimethyl Lauramide/Myristamide) — can even offer additional benefits such as increased mildness, a conditioned hair and skin feel, and fragrance solubilization.

Background: 1,4-Dioxane and Recent Legislation What is 1,4-dioxane?

1,4-dioxane is a synthetic chemical primarily used as a solvent or stabilizer in industrial applications. It also can form as an unintentional by-product during chemical manufacturing processes involving ethylene oxide (EO) or compounds containing EO. Why has New York enacted legislation?

In 2016, the U.S. EPA found levels of ≥1 ppb of 1,4-dioxane in groundwater in New York, with the highest levels detected in Long Island. In an effort to protect water quality, the New York State Legislature passed a bill in June 2019 to limit the presence of 1,4-dioxane beyond trace concentrations in household cleansing, cosmetic and personal care products. The bill was signed by New York State Governor Andrew Cuomo on December 9, 2019.

Summary of New York 1,4-Dioxane Trace Concentration Limits Household Cleansing Products and Personal Care Products

2 ppm by December 31, 2022 1 ppm by December 31, 2023

Cosmetic Products

10 ppm by December 31, 2022

What has California implemented?

California has implemented a disclosure law (CA SB258 Cleaning Products Right to Know) that came into effect January 2020. This impacts household cleaning products with residual 1,4-dioxane limits above 10 ppm. CA SB258 requires on-line disclosure in 2020 for household cleaning products with > 10 ppm 1,4-dioxane and on-label disclosure in 2021 for household cleaning products with > 10 ppm 1,4-dioxane.

22

Why are consumer products being included?

Many consumer products contain ingredients that have been produced using EO or EO-derivatives.

Common examples of these ingredients include alkyl ether sulfates, polyethylene glycols (PEGs) and ethoxylated alcohols.

How does Stepan define UP Program offerings?

Low 1,4-dioxane: Low 1,4-dioxane refers to Stepan ether sulfate products that contain a maximum of 15 ppm residual 1,4-dioxane on a 100% actives basis at time of manufacture. This typically equates to a maximum of 10 ppm residual 1,4-dioxane in high active (70%) ether sulfates and a maximum of 4 ppm 1,4-dioxane in low active (30%) ether sulfates.

Alternative Chemistries: Stepan has a variety of alternative chemistries to alkyl ether sulfates. Based on the raw materials used and the reaction chemistry, these alternatives do not support the formation of 1,4-dioxane; however, this does not guarantee the absence of 1,4-dioxane. Stepan does not include a 1,4-dioxane level on the product specification and does not routinely analyze for 1,4-dioxane associated with all alternative chemistries. Stepan encourages customers to test the 1,4-dioxane level of their final formulations in accordance with their established stability testing protocols to ensure compliance with New York and all appropriate regulations.
