What Is SLSA?
SLSA, short for Sodium Lauryl Sulfoacetate, is a mild powder-form anionic surfactant derived from renewable coconut-palm fatty alcohol. It appears as fine fluffy white powder at room temperature. SLSA possesses large-size molecular structure which cannot penetrate skin stratum corneum easily, delivering rich fluffy foam with low skin irritation.
It is well-known star raw material for solid personal-care products including shampoo bars, bath bombs and bubble bars. It can be dry-blended directly with other powder raw-materials without pre-dissolving. It can also be used in liquid cleansing formulas by dispersing under heated water phase.
Different from SLS / SLES sulfate surfactants, SLSA is sulfoacetate-structured instead of sulfate-type. It avoids over-stripping skin lipid barrier, and is qualified for sulfate-free product claims. Different from amino-acid surfactants which are mostly liquid, SLSA is powder-state, uniquely suitable for dry-mixed solid cleansing systems. Aogebio supplies high-purity cosmetic-grade SLSA in bulk, offering free samples, full qualification documents and global one-stop shipping services for cosmetic manufacturers.
Core Advantages Of Our SLSA
Coconut-Derived Refined Powder-Grade Raw Material
Multi-step purification process, low impurity, low dust agglomeration, faint neutral odor, suitable for high-end solid personal-care and sulfate-free cosmetic production.
Rich Fluffy Long-Lasting Foam Performance
Generates abundant, voluminous, stable cloud-like foam. Foam maintains good performance in bath-water environment, brings luxurious bubble experience for bath bomb and bubble-bar products.
Large-Molecule Low-Irritation Characteristic
Big molecular structure hardly penetrates skin surface. Effectively cleans surface dirt and sebum without destroying skin acid mantle, friendly for sensitive-skin and scalp-care applications.
Unique Dry-Blend Process Compatibility
Powder form supports direct dry mixing with soda, citric acid and other powder raw-materials, core raw-material for bath bomb, bubble bar and solid shampoo bar manufacturing.
Excellent Surfactant Compatibility
Compatible with amphoteric, non-ionic and other anionic surfactants. Compound with CAPB, APG series surfactants to further lower irritation and optimize foam texture.
Wide pH Stability
Stable performance within pH 5.0-7.5 near-neutral range, matches skin-friendly formula requirement.
Stable Batch Quality & Flexible Supply
Consistent batch-to-batch foam performance and physical-chemical indicators, fit for large-scale industrial production; support sample testing, small-batch trial order and large-volume bulk customization.
How SLSA Works In Cosmetic Formulations
SLSA molecules consist of lipophilic C12 lauryl alkyl tail and hydrophilic sulfoacetate head group. In aqueous environment, surfactant molecules form micelle structures to wrap dirt, sebum and contaminants, removing them during rinsing. Its large-size molecular cannot go deep into stratum corneum, so it reduces skin irritation risk significantly.
In solid bath-product systems, SLSA dry-mixed with baking soda and citric acid. When contacting bath-water, it dissolves rapidly and releases massive fluffy foam. In liquid cleansing formulas, SLSA needs to be dispersed in heated water phase (40-75℃) for full hydration. When compounded with other co-surfactants, mixed micelles are formed to improve foam creaminess and reduce skin tight-dry sensation after washing.
Important note: Wear dust-proof mask during powder handling to avoid inhalation of fine powder dust.
Main Functions & Cosmetic Application Fields
Core Functional Benefits
- • Mild cleansing agent: Remove skin / scalp surface dirt and excess sebum without over-stripping skin barrier
- • High-volume foaming agent: Produce rich, fluffy, long-lasting cloud-style foam
- • Powder-form primary surfactant: Core foaming raw-material for dry-mixed solid cleansing products
- • Co-surfactant: Compound with other surfactants to improve foam quality in sulfate--free liquid cleanser
- • Near-neutral pH characteristic, adapt to sensitive-skin and scalp-friendly formulation concepts
Suitable Cosmetic Formulas
- • Solid shampoo bar, solid body wash bar, syndet cleansing bar
- • Bath bomb, bubble bar, foaming bath truffle and bath salt products
- • Sulfate-free liquid body wash, bubble bath liquid
- • Mild facial cleanser for sensitive-skin (liquid & solid form)
- • Baby bath product, mild children foaming bath series

Formulation Guide: Dosage, Solubility & Matching Tips
Recommended dosage (based on commercial 65% active SLSA powder):
- -Bath bomb / foaming bath salt: 5%-15%
- -Bubble bar / bubble bath solid: 15%-40%
- -Solid shampoo bar / syndet bar: 10%-30%
- -Liquid sulfate-free body wash & cleanser: 2%-8%
Solubility: Hot-water dispersible powder, insoluble in oil phase; for liquid formula add into 40-75℃ heated water-phase under stirring; for solid formula can directly dry blend with powder raw-materials.
Recommended matching ingredients: Cocamidopropyl Betaine(CAPB), Decyl Glucoside, Coco-Glucoside, sodium bicarbonate, citric acid, glycerin, panthenol.
Formulation Notes:
- -When weighing and mixing SLSA powder, wear dust-proof mask, avoid inhaling fine powder dust.
- -For liquid formulations: Heat water phase to 40-75℃, slowly sprinkle SLSA powder under continuous stirring to avoid clumping; sufficient stirring time for full dispersion.
- -For solid bath-product: Dry-blend SLSA uniformly with baking soda, citric acid and other powder materials first, then add small amount of liquid binder.
- -Optimal finished-product pH maintain at 5.0-7.5; avoid long-term strong-acid or strong-alkali environment.
- -SLSA has limited salt-thickening capacity; use polymer thickener if high-viscosity liquid formula is required.
- -Seal and store under cool-dry condition; keep tightly sealed to prevent moisture absorption and caking.
