INCI: Sodium Lauroyl Sarcosinate | Also known as: Sodium Lauryl Sarcosinate  | Origin: Vegetable derived | Grade: Cosmetic | Form: Pale yellow clear liquid

Functions: Cleansing | Surfactant | Foam Boosting | Hair Conditioning | Skin Conditioning | Antistatic | Anti-residue

Used In: Sulphate Free Shampoo | Anti-Dandruff Shampoo | Facial Cleanser | Body Wash | Shaving Foam | Toothpaste | Mouthwash | Intimate Wash

Sulphate Free | Amino Acid Based | Anti-Residue | Mild Anionic | Foam Stable | Cationic Compatible | Biodegradable

Benefits

•      Delivers a rich, stable, creamy foam that does not diminish in the presence of oils or sebum, unlike some glucoside surfactants that lose foam performance when sebum is present.

•      Produces an anti-residue rinse character that removes soap film and conditioning agent buildup from hair, leaving hair feeling lighter and cleaner without the heavy coating that some amphoteric systems deposit.

•      Compatible with cationic quaternary ammonium compounds and conditioning polymers, a rare property for an anionic surfactant that allows formulators to include cationic conditioners in the same phase without a charge-interaction problem.

•      Functions as a hair conditioning agent by adsorbing onto the hair shaft, reducing static charge accumulation and improving wet and dry combability after washing.

•      CIR Expert Panel assessed as safe as used in rinse-off products and safe for use in leave-on products at concentrations up to 5 percent.

•      Readily biodegradable, derived from lauric acid and sarcosine (a naturally occurring amino acid), supporting natural origin and amino acid surfactant positioning.

•      Contributes a low cloud point effect when blended with other surfactants, reducing the risk of formula delamination at lower temperatures and improving system clarity.

•      Works effectively as a secondary mild anionic surfactant at low levels alongside SLES, SMCT, or glucosides to improve mildness, foam quality, and conditioning character without significantly changing the cleansing profile.

Applications

In a sulphate free shampoo, Sodium Lauroyl Sarcosinate acts as a mild secondary anionic that boosts foam stability and delivers a clean rinse feel. It is particularly valued in anti-dandruff shampoos where zinc pyrithione or other scalp actives can cause irritation. NaLS reduces the defatting side effect of stronger actives while keeping the scalp clean.

In an amino acid facial cleanser, it complements taurate and glutamate surfactants by adding an anti-residue property that prevents the formula from leaving a film on the skin after rinse. This is the property that gives amino acid cleansers their characteristic light, clean after-feel without the tight or dry sensation of harsher systems.

In a body wash or intimate wash, NaLS contributes mildness and conditioning to a surfactant blend. Its compatibility with cationic conditioning polymers allows the formulator to include skin conditioning actives without phase separation concerns.

In a shaving foam or gel, it stabilises foam against the lipids in shaving cream formulas, maintaining lather quality throughout the shave. It adsorbs onto skin during contact, leaving a mild conditioning layer after rinse.

In toothpaste and mouthwash, NaLS is used at 1 to 2 percent as a foaming agent with documented anti-plaque properties. It produces a foam that distributes the active dentifrice ingredients across the tooth surface. The formulator must confirm compliance with CDSCO and BIS dental product regulations for the Indian market before launch.

How to Use

For Sulphate Free Shampoo, Facial Cleanser, and Body Wash

Add to the water phase at room temperature. NaLS is a pale yellow clear liquid that disperses readily in water. As a secondary surfactant in a blended system, use at 2 to 8 percent of the formula based on the as-supplied 30% active liquid. At these levels it improves mildness, foam stability, and rinse feel without significantly changing the viscosity or primary cleansing profile.

For Anti-Dandruff Shampoo

Incorporate alongside your primary surfactant and zinc pyrithione or other scalp active. NaLS helps suspend ZPT in the formula and reduces the defatting side effect of the active, which is one reason it is a standard ingredient in many commercial anti-dandruff formulations. Confirm ZPT suspension stability in your specific formula.

For Oral Care (Toothpaste and Mouthwash)

Use at 1 to 2 percent of the finished formula as a foaming agent. Confirm compliance with CDSCO Schedule M and BIS dental product standards before launch. NaLS is a standard foaming agent in toothpaste globally, but Indian market dental product claims require regulatory clearance.

Cationic compatibility note

This ingredient is compatible with quaternary ammonium conditioning agents and cationic polymers. However, the CIR safety assessment includes a requirement that it must not be formulated with ingredients whose safety depends on their lack of absorption, or with nitrosamine-forming amines. Avoid combining NaLS with DEA-based surfactants such as Cocamide DEA or Lauramide DEA in the same formula. Route to Pooja for formulation review if uncertain.

pH adjustment

As supplied, the pH of a 10% solution is 7.5 to 8.5. Adjust the finished formula to the target skin or scalp pH using citric acid. The required dose depends on your full formula and target pH.

Technical Information

Pairs Well With

SMCT Sodium Methyl Cocoyl Taurate is a natural pairing with NaLS. Both are mild anionics with amino acid origins, and together they deliver a dense, creamy lather with excellent scalp compatibility. NaLS contributes the anti-residue rinse character; SMCT contributes the hard water performance. The combination is well suited to a premium sulphate free shampoo.

Cocamidopropyl Betaine (CAPB) adds foam density and mildness to an NaLS base. This is a conventional mild cleanser pairing, with NaLS as the primary cleansing anionic and CAPB softening the irritation potential and building foam stability.

Decyl Glucoside blends with NaLS to create a sulphate free cleanser where the glucoside provides rapid foam build and the sarcosinate provides the anti-residue rinse feel. At lower levels NaLS also improves the mildness of a glucoside primary base.

Betaine Powder adds humectancy and a mild skin feel improvement to an NaLS based cleanser. It softens the after-rinse skin and scalp sensation when added at 1 to 3 percent.

Citric Acid Monohydrate is the pH adjustment agent. As supplied at pH 7.5 to 8.5, the formula must be adjusted to the target skin or scalp pH before adding heat-sensitive actives or fragrance.

Euxyl PE 9010 provides broad spectrum preservation in any water based formula containing NaLS. Required in all rinse-off and leave-on formulas.

Important Information

Sodium Lauroyl Sarcosinate is supplied as a pale yellow clear liquid with an active matter content of approximately 30 percent. The finished formula must be adjusted to the target skin or scalp pH using citric acid. Handle with standard eye protection at working concentrate.

Formulation restriction: this ingredient must not be combined with co-ingredients that can form N-nitroso compounds, including DEA-based surfactants such as Cocamide DEA or Lauramide DEA. This is a standard CIR-stated restriction for sarcosinate surfactants. The ingredient itself as supplied has been tested and no nitrosamines were detected. The restriction applies to the formulation context, not the ingredient in isolation. Route any formula containing NaLS alongside amine-type ingredients to your R and D team for review before launch.
