Disodium Laureth Sulfosuccinate. (May Contain: CI 77266 [nano] / Black 2

TL;DR. This ingredient is a mild anionic surfactant used in rinse-off cleansers to lift oil and soil while building foam. It is common in shampoos, face washes, body washes, and baby cleansing formulas where a gentler cleansing profile is desired.

What does Disodium Laureth Sulfosuccinate. (May Contain: CI 77266 [nano] / Black 2 do in a cosmetic formula?

This ingredient is a mild anionic surfactant used in rinse-off cleansers to lift oil and soil while building foam. It is common in shampoos, face washes, body washes, and baby cleansing formulas where a gentler cleansing profile is desired.

Is Disodium Laureth Sulfosuccinate. (May Contain: CI 77266 [nano] / Black 2 clean?

This ingredient is generally well tolerated for a cleansing surfactant, but it can still contribute to dryness or stinging at higher use levels or in leave-on exposure. Clean-standard friction comes mainly from ethoxylation-related residue controls, especially 1,4-dioxane and ethylene oxide, and the listed optional nano colorant may add separate scrutiny.

Is Disodium Laureth Sulfosuccinate. (May Contain: CI 77266 [nano] / Black 2 sustainable?

This material is often partly bio-based when the fatty alcohol source is coconut or palm, and partly synthetic because of its further processing. It is expected to biodegrade well in wastewater, while palm sourcing and nano-pigment disclosure are the main sustainability considerations.

Is Disodium Laureth Sulfosuccinate. (May Contain: CI 77266 [nano] / Black 2 COSMOS-approved?

It is generally not aligned with COSMOS organic or natural standards because ethoxylated surfactants do not fit the standard’s preferred processing rules. From a Green Chemistry view, it has positives in mildness and biodegradability, but weaker alignment on petrochemical processing inputs and residue management.

How does Disodium Laureth Sulfosuccinate. (May Contain: CI 77266 [nano] / Black 2 work chemically?

The molecule is a high-molecular-weight anionic surfactant built from a C12 fatty chain, a polyoxyethylene spacer, and a dianionic sulfonated ester salt, which helps explain its relatively mild cleansing behavior. It is typically used around 3 to 15% active matter in cleansers, performs best in mildly acidic to neutral systems, and is commonly paired with amphoteric or nonionic surfactants for foam quality and better skin feel.
