Lauryl Hydroxysultaine (LHS 45% Liquid), registered under CAS NO. 13197-76-7, represents the pinnacle of modern amphoteric surfactants. Engineered for premium skin and hair care formulations, it offers an exceptional combination of foaming performance, thickening synergy, and irritation mitigation. Chemically distinct from standard alkyl betaines, its molecular configuration incorporates a hydroxyl sulfobetaine group, allowing it to remain highly stable and effective across an extreme pH spectrum.
In modern personal care development, the shift away from sulfates and harsh ethoxylated surfactants has accelerated the demand for high-performance amphoterics. LHS 45% serves as a critical component, bridging the gap between mildness and high foaming efficiency. Its compatibility with anionic, nonionic, and cationic ingredients makes it a versatile tool for cosmetic chemists looking to build structured, aesthetically pleasing, and skin-friendly formulations.
This technical summary outlines the core chemical characteristics of our premium LHS 45% liquid:
LHS 45% exhibits outstanding resistance to calcium and magnesium ions. Unlike traditional soaps and anionic surfactants that lose efficiency in hard water, LHS maintains its foaming and cleansing properties across varying water hardness levels.
When combined with anionic surfactants such as SLES or amino acid-based cleansers, Lauryl Hydroxysultaine creates a compact micellar network. This increases viscosity efficiently, reducing the overall requirement for inorganic salt thickeners.
The quaternary-like nitrogen structure under slightly acidic conditions allows LHS to adsorb onto keratinous substrates (hair and skin). This delivers a smooth, conditioning feel, reduces static charge in hair, and improves wet combing.
The deployment of Lauryl Hydroxysultaine 45% varies dramatically depending on regional market preferences, regulatory environments, and local consumer demographics. Understanding these localized trends is essential for global brands customizing their product line-ups.
Driven by clean beauty regulations, sulfate-free and PEG-free cosmetic formulations dominate. LHS 45% is primarily utilized as a primary co-surfactant to boost foam performance in high-end, mild body washes and baby care products, where low eye irritation indices are mandatory.
In highly competitive markets like Japan, South Korea, and China, mildness is paired with sensory performance. Brands incorporate LHS 45% into dense-foaming facial cleansers, shaving foams, and scalp care shampoos to meet the demand for micro-bubble textures and fast rinsing.
Faced with high water hardness challenges, formulation stability is critical. LHS 45% is integrated into family-sized shampoo lines and liquid hand soaps to maintain robust cleansing and lather quality under variable regional water conditions.
The global amphoteric surfactants market is transitioning from legacy ingredients like Cocamidopropyl Betaine (CAPB) toward Lauryl Hydroxysultaine. While CAPB remains widely used, concerns over residual free amines (specifically 3-dimethylaminopropylamine or DMAPA) and associated skin sensitization risks have led premium formulators to seek safer alternatives.
LHS 45% has emerged as the preferred replacement, offering an even lower irritation profile, superior thermal stability, and better compatibility with cationics. This transition is supported by a rising global demand for mild baby care products, premium natural shampoos, and clinical-grade dermatological washes.
| Property | LHS 45% | CAPB 35% |
|---|---|---|
| Active Content | 45% | 30-35% |
| Irritation Profile | Extremely Low | Low to Moderate |
| Hard Water Stability | Excellent | Moderate |
| Foam Density | Very High | High |
The roadmap for Lauryl Hydroxysultaine centers around green chemistry advancements and the reduction of manufacturing footprints. Historically, surfactants relied heavily on petrochemical-derived carbon chains. Today, the focus is on 100% bio-based inputs.
Our current R&D pipeline targets several key areas:
Transitioning toward 100% RSPO (Roundtable on Sustainable Palm Oil) certified fatty alcohols for the lauryl hydrophobic tail, ensuring zero deforestation in the supply chain.
Optimizing the synthesis reaction between dodecyl dimethyl amine and sodium 3-chloro-2-hydroxypropanesulfonate to minimize inorganic salts and free amine levels.
Modifying the physical state of the surfactant blend to allow cold-processing at lower temperatures, reducing energy consumption during final manufacturing.
Operating out of Suzhou, Suzhou Yuantairun Chemical Co., Ltd. leverages China's advanced chemical manufacturing infrastructure to guarantee quality, cost efficiency, and reliable global delivery.
Our facility is equipped with automated glass-lined reactors and real-time monitoring systems that track temperature, pressure, and raw material feed rates. This configuration prevents batch variation, keeping active matter and free amine levels within tight parameters. Strategically located near major shipping corridors, we offer streamlined logistics to ensure reliable supply timelines for international buyers.
Navigating chemical import regulations requires close coordination between suppliers and formulators. We support our global partners with a comprehensive regulatory support package:
We provide full dossier documentation to support REACH compliance for European imports, streamlining clearance and customs processing.
Lauryl Hydroxysultaine is fully listed in China's Inventory of Existing Cosmetic Ingredients (IECIC), making it suitable for brands exporting products to the Chinese market.
We offer full access to Safety Data Sheets (SDS), Certificates of Analysis (COA), and technical datasheets (TDS) for every shipped batch.
