SODIUM C12-13 PARETH SULFATE ●
TL;DR. This ingredient is an anionic cleansing surfactant used to lift oil and soil, build foam, and support rinse-off cleansing in shampoos, body washes, and facial cleansers.
What does SODIUM C12-13 PARETH SULFATE do in a cosmetic formula?
This ingredient is an anionic cleansing surfactant used to lift oil and soil, build foam, and support rinse-off cleansing in shampoos, body washes, and facial cleansers.
Is SODIUM C12-13 PARETH SULFATE clean?
From a clean-beauty perspective, it has friction because it is ethoxylated and sulfated, with possible trace processing residues such as 1,4-dioxane if purification is not well controlled. It can also feel drying or irritating at higher active levels, especially in formulas without amphoteric or nonionic co-surfactants.
Is SODIUM C12-13 PARETH SULFATE sustainable?
This material is typically made from C12-C13 fatty alcohol feedstocks that may be petrochemical, palm-derived, or mixed-source. It is generally biodegradable, but its ethoxylated production route and feedstock traceability are the main sustainability concerns.
Is SODIUM C12-13 PARETH SULFATE COSMOS-approved?
It is generally not permitted under COSMOS-natural or COSMOS-organic because ethoxylation is not an allowed Green Chemistry process in that framework. Its biodegradability is a positive point, but the synthetic processing route keeps it poorly aligned with COSMOS-style natural formulation standards.
How does SODIUM C12-13 PARETH SULFATE work chemically?
The molecule combines a C12-C13 hydrophobic fatty chain with ethoxy units and a negatively charged it head group, which gives strong detergency and high foam in water. It is usually formulated in rinse-off systems and often paired with milder co-surfactants to reduce defatting, improve viscosity, and moderate irritation potential.
