The following information is provided to assist in product recommendation associated with Stepan’s “sulfate-free” surfactants and blends for Personal Care applications. It outlines flash foam, Biorenewable Carbon Index, and other surfactant properties of a select group of Stepan surfactants compared to competitive chemistries in the market place today. Stepan defines a product to be “sulfate-free” if it does not contain Alkyl Sulfates and Alkyl Ether Sulfates as per INCI nomenclature. This definition does not include inorganic sulfates, e.g. Sodium Sulfate formed as a by-product. Two representative sulfate products are noted for comparison purposes.
*These products do not meet Stepan’s definition of sulfate-free as defined above. NE - Not Evaluated

The information on the following pages reflect a system containing 12% active of the noted surfactant and 3% active of AMPHOSOL® HCA (Cocamidopropyl Betaine). This includes appearance, foaming, and sensory properties.
Surfactant System Properties
A 12% active surfactant to 3% active Betaine ratio is typical of conventional sulfate systems. Use levels and ratios of sulfate-free systems will vary.

Foam Appearance and Sensory Properties
5g surfactant system dispensed onto a wet pouf and squeezed 7 times with both hands (5 panelists). Foam appearance, foam feel,
skin feel and risibility was observed.
The significant attributes were noted for skin feel and risibility. For additional information, please contact Stepan U.S. Technical Service at [email protected].

Foaming Properties Shake Foam Test (0.2% active solution at 25°C)
Shake Foam: This method evaluates the initial foam generation (flash foam) of a surfactant in solution as well as foam stability (after 5 minutes). The test simulates the generation of foam via agitation of the test solution and then is repeated with the addition of oil.
Stepan Sulfate-free Surfactants and Surfactant Blends provide equivalent or improved foam volume compared to the competitive surfactants listed above.
Zein Score: Amount of Zein protein solubilized by a given surfactant compared to the amount solubilized by Sodium Lauryl Sulfate (SLS). The Zein Score for SLS is 100. The less protein solubilized, the milder the surfactant.
There are many sulfate-free surfactants in the marketplace; most of them are mild. Differences may be seen in lather and sensory attributes. Stepan Sulfate-free Surfactants and Surfactant Blends provide equivalent to improved foam and skin feel attributes compared to the competitive surfactants noted in this document. LATHANOL® LAL products give a rich, luxurious lather. ALPHA-STEP® PC-48 is a methyl ester sulfonate-based surfactant- your top Stepan surfactant choice when you want high foam volume and quick rinsing. BIO-TERGE® AS-40 is a cost-effective, high-foaming surfactant to consider for non-natural Personal Care cleansing products. STEPAN-MILD® PCL and STEPAN-MILD® LSB are easy-to-handle, high-performing blends.
Biorenewable Carbon Index (BCI): The BCI is a value based on the percent carbon derived from a biorenewable resource. Biorenewable is defined by Stepan as originating from animal, plant or marine material. BCI is calculated by taking the number of biorenewable carbons divided by the total number of carbons in the idealized molecule, multiplied by 100. Critical Micelle Concentration (CMC): The minimum amount of surfactant needed to form a stable micelle. Stable micelles are required to form emulsions. It is an emulsion that captures dirt and oil and carries it away from the surface being cleaned. It is important to be above the CMC to maximize the formulations cleaning ability.
