Explore our top-tier cationic surfactants, polymers, and active ingredients engineered for exceptional conditioning, emulsification, and softening capabilities.
A comprehensive evaluation of chemical mechanics, interfacial deposition, and formulation kinetics in professional hair care systems.
Human hair keratin naturally maintains an isoelectric point at approximately pH 3.67. Due to daily environmental stresses, UV radiation, and thermal treatments, disulfide bonds oxidize into cysteic acid groups. This process significantly increases the surface density of negative charges on the cuticle. Standard anionic surfactants cleanse but also exacerbate cuticle friction and static charge.
Cationic surfactants (such as quaternary ammonium compounds, esterquats, and cationic polymers like Polyquaternium-7 and Polyquaternium-39) are positively charged. They undergo a targeted electrostatic deposition on the negatively charged sites of the hair shaft. This forms a monomolecular hydrophobic film that reduces wet combing force, neutralizes static charge, and seals the cuticular scales.
"By precision-engineering the alkyl chain length (typically C16 to C22), Suzhou Yuantairun allows formulators to dial in the exact balance of conditioning, weight, and rinseability required for fine, normal, or damaged hair types."
Reduces the electrostatic flyaway effect by coating hair fibers with positive charges.
Long-chain fatty radicals mimic the hair's natural F-layer (18-methyleicosanoic acid) for restored shine.
Combines synergistically with non-polar agents (e.g. Dimethicone) to anchor them to damaged zones.
A precise comparison profile highlighting the properties of cationic surfactants, co-emulsifiers, and structural modifiers used in hair formulations.

The chemical industry is pivoting toward green principles. Suzhou Yuantairun's R&D roadmap focuses on clean chemistry alternatives.
Replacing traditional persistent monoalkyl and dialkyl quaternary ammonium compounds (such as DTDMAC) with ester-linked equivalents (Esterquats, CAS 91995-81-2). These links degrade rapidly in wastewater systems through enzymatic hydrolysis, mitigating aquatic toxicity.
We are transitioning our feedstocks away from petrochemical chains to natural oils (such as coconut and RSPO-certified palm oil). Our goal is to secure high-purity, sustainable raw materials that offer carbon-neutral footprints to meet global sustainability standards.
Developing functionalized biopolymers (e.g. starch-based and protein-based cationics like Potassium Cocoyl Hydrolyzed Oat Protein) that synergize with minimal surfactant dosages to deliver high-performance conditioning profiles.
Solving rheological, physical-chemical, and stability challenges across diverse personal care applications.
Formulating clean-beauty conditioners requires replacing harsh surfactants with milder alternatives. We provide non-ionic APG surfactants (APG0810, APG1214) paired with mild amphoterics (CAB-35) and cationic Polyquaternium-7 to create clear, rich, and skin-friendly personal care formulations.
Application target: Sensitive-scalp shampoos and baby care washes.
By combining cationic conditioners (such as Cetrimonium Chloride) with fatty alcohols (Cetyl Stearyl Alcohol), we establish a structured liquid crystal lamellar gel phase. This network stabilizes dimethicone droplets and controls formulation viscosity to ensure a luxurious application experience.
Application target: Premium hair masks, salon-strength conditioners.
