Technical insight into chemical properties, global supply dynamics, and sustainable synthesis by JIMPOCHEM CO., LTD.
Lauryl Hydroxysultaine (LHS), registered under chemical abstract number CAS 13197-76-7 (IUPAC: 3-[dodecyl(dimethyl)azaniumyl]-2-hydroxypropane-1-sulfonate), represents the pinnacle of zwitterionic surfactant evolution. Featuring a hydrophobic C12 lauryl chain coupled with a hydroxylated propyl sulfobetaine headgroup, CAS 13197-76-7 exhibits exceptional molecular stability across extreme pH ranges (pH 2 to 12) and ultra-high electrolytic concentrations. Unlike conventional carboxyl betaines (e.g., Cocamidopropyl Betaine - CAPB), the sulfonate group ($R\text{-}SO_3^-$) in LHS retains complete ionization even in hyper-acidic or concentrated salt solutions, mitigating cloud-point phenomena and preventing phase separation in high-performance formulations.
Formulators seeking next-generation sulfate-free personal care and industrial solutions prioritize CAS 13197-76-7 due to its superior micellar synergism. The inclusion of the secondary hydroxyl group ($-\text{OH}$) on the sultaine backbone increases hydrogen bonding capacity within the surfactant micelle interface. This yields a 35% higher flash-foam volume, reduced Critical Micelle Concentration (CMC), and unparalleled skin mildness (Zein protein denaturation score $< 1.2\%$). Furthermore, LHS acts as a natural viscosity builder in salt-sensitive or EO-free (Ethylene Oxide-free) systems, dramatically lowering the need for synthetic polymeric thickeners.

Why leading global brands are shifting sourcing strategies toward China CAS 13197-76-7 manufacturers.
Consumer demand across North America and Europe is overwhelmingly shifting toward gentle, non-irritating skin and hair cleansing solutions. Formulators are actively phasing out traditional Sodium Lauryl Sulfate (SLS) and Sodium Laureth Sulfate (SLES) due to skin barrier disruption concerns. CAS 13197-76-7 acts as an essential co-surfactant in sulfate-free chassis, mitigating the harshness of secondary surfactants while producing micro-dense, creamy lather that consumers associate with premium luxury brands.
Beyond cosmetics, industrial procurement managers in Europe and Asia-Pacific require chemical compounds that operate under hostile chemical environments. CAS 13197-76-7 excels in heavy-duty acidic descalers, hard-surface degreasers, vehicle wash concentrates, and industrial foamers. Its resistance to alkaline hydrolysis and high stability in up to 15% hydrofluoric/phosphoric acid solutions make it an indispensable surfactant for industrial manufacturing.
The global oilfield chemicals market is witnessing rapid adoption of sultaine-based surfactants for high-temperature, high-salinity (HTHS) reservoirs. Lauryl Hydroxysultaine CAS 13197-76-7 functions as a high-performance foaming agent and fluid diverter in hydraulic fracturing and EOR. It maintains interface tension reduction ($< 10^{-2} \text{ mN/m}$) even under formation brine containing over 200,000 ppm total dissolved solids (TDS).
How JIMPOCHEM leverages 500+ acres of automated infrastructure in Jinan Chemical Park to deliver unmatched commercial stability.

This technological breakthrough ensures full compliance with strict global standards including EU REACH, US FDA, and ASEAN Cosmetic Directives.
Technical implementation strategies for formulation chemists across target end-use industries.
Dosage: 3.0% – 12.0%
In gentle facial washes and tear-free infant formulations, CAS 13197-76-7 dramatically reduces the ocular and dermal irritation potential of primary anionic surfactants like Sodium Lauroyl Sarcosinate or Sodium Cocoyl Isethionate (SCI). It improves rinseability without leaving heavy film residues.
Dosage: 2.0% – 8.0%
Thanks to its quaternary ammonium nitrogen center, LHS carries localized positive charges under acidic conditions. It binds selectively to damaged, negatively charged keratin strands, providing anti-static behavior, enhanced wet combing capability, and exceptional compatibility with active anti-dandruff agents like Zinc Pyrithione (ZPT).
Dosage: 5.0% – 15.0%
LHS CAS 13197-76-7 remains fully soluble and stable in concentrated $\text{HNO}_3$, $\text{H}_3\text{PO}_4$, or $\text{NaOH}$ baths. It acts as a wetting agent, corrosion inhibitor synergist, and foam booster in CIP (Clean-in-Place) systems for dairy, brewery, and metal surface finishing plants.
