Sodium Lauroyl Sarcosinate, 100 ml

Sodium Lauroyl Sarcosinate is an anionic surfactant from the group of sarcosinates – it is the sodium salt of lauroyl sarcosinate, formed by reacting a fatty acid (most commonly lauric acid from coconut/palm sources) with sarcosine (N-methylglycine), followed by neutralisation to the sodium salt.
In cleansing products it is valued for its good cleansing efficacy while providing a more pleasant skin feel compared to some classical sulfates. It typically produces a rich, mild foam, has good slip, and is often used as a primary or secondary surfactant in modern sulfate-free formulations.

Key benefits

• Sulfate-free anionic surfactant – an alternative to SLS/SLES in milder formulations.
• Excellent foaming – creates a rich, fine foam and improves the “foam feel”.
• Good cleansing performance with a more pleasant feel on skin and hair (compared to many strong anionic surfactants).
• Improves slip – often contributes to easier detangling and a smoother feel after rinsing.
• Synergy in surfactant blends – suitable for combining with amphoteric and non-ionic surfactants.

Suitable for products such as

• Shampoos (liquid and gel) – especially “sulfate-free” types.
• Shower gels and mild body wash gels.
• Facial cleansing gels and foams (rinse-off) – with a properly adjusted formula.
• Intimate hygiene (rinse-off) – in combination with mild co-surfactants and an appropriate pH.
• Exfoliating cleansing gels and products where you need good degreasing with a pleasant foam.

Use in formulation

• Soluble in: water (depending on the supplied form – solution/powder); it is insoluble in oils.
• Mixable with: anionic, amphoteric and non-ionic surfactants; it is often combined with Sodium Cocoamphoacetate, Cocamidopropyl Betaine or glucosides for a milder profile.
• Compatible with: common humectants (glycerin, propanediol), polymeric thickeners for surfactant systems and salt-thickening (the outcome depends on the overall surfactant blend).
• Dosage (guideline): as a primary or secondary surfactant in cleansing products; the aim is to set the desired level of active surfactants in the finished product.
• pH and stability (guideline): sarcosinates are usually formulated in a mildly acidic to neutral range; at very low pH, the stability and clarity of the system may decrease – always fine-tune pH according to the full composition and perform testing.

Safety and storage

• Intended for cosmetic use; avoid contact with eyes and mucous membranes.
• Store in a tightly closed container, in a dry place, away from direct sunlight and sources of heat.
• For sensitive skin and for facial/intimate hygiene products, always test the final formula and adjust pH and fragrance.

Physical properties

• Appearance: depends on the form – powder or clear to slightly opalescent liquid (aqueous solution).
• Character: anionic surfactant with the ability to form rich foam and improve slip.
