SODIUM MYRETH SULFATE
Sodium Myreth Sulfate is an anionic surfactant. Its molecule combines a long fatty segment, a short chain of ethoxylated units, and a sulfate group paired with sodium. That arrangement lets the ingredient work at the boundary between water, oil, and grime, rather than behaving like either a plain salt or an oil.
SODIUM MYRETH SULFATE: what it is
Sodium Myreth Sulfate is an anionic surfactant. Its molecule combines a long fatty segment, a short chain of ethoxylated units, and a sulfate group paired with sodium. That arrangement lets the ingredient work at the boundary between water, oil, and grime, rather than behaving like either a plain salt or an oil.
The “myreth” part refers to a myristyl, fourteen-carbon chain joined to ethylene oxide units; for this material, the stated average is one to four units. This detail distinguishes Sodium Myreth Sulfate from sulfates made with a different fatty chain or degree of ethoxylation. An ingredient list alone does not identify the commercial source of the raw material in a particular product.
SODIUM MYRETH SULFATE: what it does in cosmetics
In rinse-off products, Sodium Myreth Sulfate helps water spread through and lift oily material from a surface. In everyday terms, that supports the cleansing feel of shampoos, liquid washes, and similar washable products; it is not included to stay behind as a moisturizing layer on skin or hair.
It can also support foam formation and help oil and water remain more evenly dispersed while the product is being used. Foam by itself is not a measure of product quality or mildness: the final experience depends on the surfactants, thickeners, and conditioning agents used alongside it. The available classifications describe these formulation roles, not a treatment for skin or hair concerns.
