Products Description
Disodium Lauryl Sulfosuccinate (INCI: Disodium Lauryl Sulfosuccinate, CAS:13192‑12‑6) falls under sulfosuccinate‑class anionic surfactants, engineered as a sulfate‑free alternative to conventional SLS/SLES cleansing agents for modern personal‑care and household cleaning formulations. Thanks to its large‑size molecular framework combining long‑chain lauryl hydrophobic segment paired with dual hydrophilic sulfonate and carboxylate groups, this ingredient cannot easily penetrate the human stratum corneum, which drastically lowers skin irritation risk compared to harsh sulfate surfactants.
This cosmetic‑grade transparent liquid delivers balanced detergency and moderate degreasing performance, helping preserve skin's natural lipid barrier instead of over‑stripping surface sebum. It generates rich, velvety, long‑lasting creamy lather, and maintains stable surface‑active performance even under hard‑water working conditions. It demonstrates outstanding formula compatibility when blended with other anionic, non‑ionic and amphoteric surfactants; compounding it into mixed surfactant systems effectively cuts down overall irritation levels of finished cleanser products.
From an eco‑friendly perspective, this raw material achieves above 90% biodegradation rate within 28‑day testing cycles and leaves no persistent organic residues, complying with major global green cosmetic requirements. Two commercial grades are available: cosmetic grade for beauty‑care manufacturing and industrial grade for general cleaning projects. Our standard offering is 30.0±2.0% active transparent liquid, with a 12‑month shelf‑life under proper sealed storage conditions.

Application
Disodium Lauryl Sulfosuccinate works both as primary surfactant or mildness‑boosting co‑surfactant across multiple rinse‑off formula scenarios. It reduces skin tightness, dry feeling and scalp discomfort caused by strong cleansing components. Recommended addition ratios vary depending on end‑product categories:
- Facial Cleansing Items: Sulfate‑free foaming face wash, amino‑acid blended cleanser formulas. Suggested loading: 8%‑30%. Perfect for sensitive‑target facial care lines.
- Hair‑care Solutions: Low‑irritation daily shampoo, hair‑color protecting shampoo, scalp cleansing foam. Suggested loading:5%‑25%. It helps minimize cuticle damage while supporting creamy lather generation.
- Body Cleansing Series: Bath foam, mild hand‑washing foam, shaving foaming base. Suggested loading:10%‑40%. Rinses clean without sticky film left on skin surface.
- Household Gentle Cleaners: Low‑irritation fabric washing liquid, soft‑surface household detergent. Suggested loading:3%‑15%.

Frequently Asked Questions
Q1: Is Disodium Lauryl Sulfosuccinate suitable for eczema‑prone sensitive‑skin cosmetic products?
A1: Yes. This low‑irritation anionic surfactant is widely adopted for sensitive‑skin oriented rinse‑off formulas. Its macromolecular structure limits skin penetration, bringing minimal irritation risk. Still, finished goods are suggested to complete patch‑test validation before formal launch.
Q2: What typical dosage should I adopt for sulfate‑free foaming facial cleanser?
A2: Recommended addition range is 8%‑30%. When compounded together with amino‑acid surfactants, you can lower its loading while still maintaining favorable mild‑foam output.
Q3: How does this sulfosuccinate ingredient compare functionally with SLS / SLES surfactants?
A3: Unlike sulfate‑based SLS/SLES, Disodium Lauryl Sulfosuccinate is sulfate‑free. It yields comparable creamy foam performance yet with far lower skin‑barrier disruption potential, reducing post‑wash tightness and dryness. Degreasing power is moderate to avoid excessive lipid stripping.
Q4: Can I blend this raw material with amino‑acid‑class surfactants inside one formula system?
A4: Absolutely. It exhibits excellent compatibility with amino‑acid surfactants. Blending them together can lift foam texture and effectively mitigate overall irritation of the whole surfactant complex.
Q5: What storage conditions should I follow for stock‑keeping this liquid raw material?
A5: Store in cool, dry, well‑ventilated warehouse space. Keep containers sealed and shielded from direct sunlight. Under qualified storage environment, shelf‑life reaches 12 months from manufacturing date. After opening drums, finish consumption as soon as possible.
Q6: What shipping modes can I select for bulk orders of Disodium Lauryl Sulfosuccinate?
A6: Small‑weight orders under 100 kg can go by express door‑to‑door service. For 100‑1000 kg volume we offer air‑freight airport‑to‑airport option. Orders above 300 kg are suitable for ocean sea‑freight port‑to‑port shipment. Customs clearance support is required for sea and air freight.
Q7: Can I use this ingredient for leave‑on skincare products such as cream or serum?
A7: It is allowed for leave‑on products only at limited concentration ≤3%. High‑concentration addition in non‑rinse formulas is not advised, due to potential mucosal irritation risk.
Q8: Will hard‑water condition damage foaming performance of Disodium Lauryl Sulfosuccinate?
A8: It owns decent hard‑water tolerance. Foam stability remains relatively good when calcium‑magnesium ions exist in water environment, compared to many ordinary anionic surfactants. For extreme hard‑water scenarios, adding chelating agent EDTA‑2Na will further optimize final performance.
