Liquid Lauramidopropyl Betaine, LAB-35 Amphoteric Surfactant, High Purity Mild Foaming Agent, Low Irritation Thickening Stabilizer, Antistatic Conditioning Agent, Daily Chemical Compound Surfactant, High Stability Cleansing Raw Material
Lauramidopropyl Betaine-CAS 4292-10-8
Liquid Lauramidopropyl Betaine (LAB-35) is a high-purity mild amphoteric surfactant synthesized from single carbon chain lauric acid raw materials through refined amination and betainization processes.
Different from coconut oil-based CAB-35 with mixed carbon chains, LAB-35 adopts standardized single lauryl carbon chain structure, featuring purer composition, more stable performance and lower residual impurities.
It combines the advantages of anionic and cationic surfactants, maintaining excellent chemical stability in full pH range and complex hard water environments. The product has ultra-low skin and eye irritation, superior foam fineness and denseness, and can significantly optimize the foam structure of compound formulas.
It has outstanding thickening and stabilizing effects, which can effectively improve the viscosity of dilute surfactant systems, prevent product delamination and precipitation, and enhance long-term storage stability.
In addition, it possesses excellent hair softening, antistatic and soothing properties, which can reduce hair tangling and dry frizz, and relieve skin dryness and tightness after washing. With good water solubility, full formula compatibility and complete biodegradability, it is a high-quality upgraded alternative to conventional betaine surfactants, widely used in high-end mild personal care cleansing formulas.
Key Benefits
• High Purity & Ultra-low Irritation: Single carbon chain pure structure, low impurity content, far milder than ordinary mixed-chain betaine, safe for sensitive skin and long-term daily cleansing.
• Super Fine & Dense Stable Foam: Uniform molecular structure brings finer, more elastic and durable foam, effectively improving the rough foam defect of traditional betaine products.
• Efficient Thickening & Strong Stabilization: Excellent viscosity adjustment performance, significantly increase formula viscosity, optimize system uniformity, and solve long-term storage delamination problems.
• Full pH & Hard Water Adaptability: Stable performance in acidic, neutral and alkaline environments, excellent hard water resistance, no performance attenuation in complex water quality.
• Multi-functional Compound Upgrade: Perfectly compatible with anionic, nonionic and cationic surfactants, neutralize formula irritation, balance cleaning power and mildness, and upgrade product comprehensive texture.
• Eco-friendly & High Cost-performance: Fully biodegradable, green and safe, stable batch quality, lower odor and better purity than conventional betaine, suitable for high-end product mass production.
Applications
• High-end Facial Cleansing Products: Pure mild facial cleanser, sensitive skin soothing cleansing foam, high-end low-irritation facial cleansing formula.
• Premium Hair Care Series: Mild high-grade shampoo, anti-frizz conditioning shampoo, static-free fluffy hair care products.
• High-quality Body Cleansing: Luxury moisturizing body wash, long-lasting mild hand sanitizer, high-standard personal daily cleansing products.
• Oral Care Formulas: High-purity mild toothpaste, low-irritation oral cleaning foaming base, high-end oral care raw materials.
• High-grade Household Detergents: Mild high-quality dish soap, skin-friendly laundry detergent, high-stability compound cleaning products.

Frequently Asked Questions (FAQ)
•Q1: What is the difference between LAB-35 and CAB-35?
A1: LAB-35 is lauric acid single carbon chain betaine with purer composition, lower odor and fewer impurities; CAB-35 is coconut oil mixed carbon chain betaine. LAB-35 has milder performance, finer foam and more stable quality, more suitable for high-end cosmetic formulas.
•Q2: What is the recommended formula addition ratio?
A2: 2%-8% for high-end shampoo and body wash, 1%-5% for mild facial cleanser, 1%-3% for oral care products, 2%-6% for high-grade household detergents, adjustable according to product positioning.
•Q3: What are the core advantages of LAB-35 in compound formulas?
A3: It can efficiently thicken and stabilize foam, neutralize the irritation of anionic surfactants, improve formula system uniformity, and effectively avoid product delamination and odor problems, upgrading product grade.
•Q4: Is LAB-35 suitable for sensitive skin and high-end cosmetics?
A4: Yes, with single pure carbon chain structure, ultra-low irritation and low impurity characteristics, it fully meets the raw material standards of high-end skin care and sensitive skin mild cleansing products.
•Q5: Does LAB-35 have antistatic hair care effect?
A5: Absolutely yes, it has excellent hair conditioning performance, which can smooth hair scales, eliminate static electricity, reduce dry frizz and tangling, and keep hair smooth and fluffy for a long time.
•Q6: Does the product support bulk supply and global export?
A6: The product complies with EU, US and China cosmetic industry standards, with stable batch quality and sufficient inventory. It supports long-term bulk supply and global export, and provides professional formula debugging technical services.
