In hair care formulations, the "charge density" and "emulsion particle size" of cationic silicone emulsions directly dictate their adsorption on hair and the extent of combing improvement. Conventional amino silicone emulsions often suffer from large particle size and poor centrifugal stability (>1ml), leading to oil floating and demulsification upon shampoo dilution, resulting in conditioning failure. While some micro-emulsions are stable, their low amino content limits "soft-touch" improvement for damaged hair. As color/perm-damaged hair demands "tangle-free wet combing, non-frizzy dry combing, soft yet non-limp" effects, sourcing a cationic amino silicone emulsion with 27-35% solid content, 10-18s (No.4 cup) viscosity, ≤0.5ml centrifugal stability (2500rpm×15min), and containing Cetrimonium Chloride & Trideceth-12 has become the core gap for domestic hair conditioning agent localization.
Addressing this "cationic stable emulsion core-care" pain point,
Anhui IOTA Silicone Oil Co., Ltd. (IOTA) officially launches
Cationic Amodimethicone Emulsion IOTA 95099 (INCI: Amodimethicone (and) Cetrimonium Chloride (and) Trideceth-12). Characterized by "white emulsion, density 0.980-1.000, 27-35% solid, ≤0.5ml centrifugal stability, 0.5-2.0% wide dosing," and backed by "amino adsorption core-repair + cationic emulsifier locking + high-stability anti-dilution," it serves as the "core-care anchor" for shampoos, conditioners, hair masks, and hair colorants.
Molecular Architecture: Amino Silicone + Cationic Emulsifier Dual-Anchor Logic
The core competitiveness of IOTA 95099 stems from its synergistic emulsification system of "aminofunctional polydimethylsiloxane + cationic surfactants":
-
Amino Adsorption Core-Repair: Amodimethicone molecules bear terminal amino groups (–NH₂/–NH–), exhibiting strong electrostatic adsorption to negatively charged damaged hair (lifted cuticles, exposed cortex). They penetrate into the hair cortex, filling internal voids, and enhancing hair strength and elasticity from the "core".
-
Cationic Emulsifier Locking: Cetrimonium Chloride (cationic emulsifier) anchors the silicone droplet via its long cetyl chain (C16), while its quaternary ammonium head adsorbs onto the hair surface, forming a "silicone-emulsifier-hair" sandwich structure, preventing silicone detachment during shampoo dilution or rinsing.
-
High-Stability Anti-Dilution: Trideceth-12 (non-ionic co-emulsifier) synergizes with the cationic emulsifier to lower interfacial tension, forming a uniform, highly stable emulsion (≤0.5ml centrifuge). It remains intact even under high shampoo dilution (1:10~1:20), preventing oil floating or demulsification.
Performance Leap: From "Oil Floating Fake Slip" to "Wet-Comb Core-Care"
Incorporating IOTA 95099 enables qualitative leaps in hair care formulations:
-
Damaged Hair Repair: For color/perm-damaged hair, amino groups penetrate for core repair, cationic emulsifiers lock position, significantly lifting hair strength and reducing breakage; improvement perceivable at 0.5-2.0% dosage.
-
Dual Wet/Dry Combing: Drastically reduces wet-combing resistance during washing (minimizing cuticle damage); post-drying, hair is smooth and non-frizzy, easy to comb without tangling, exhibiting a natural "soft yet non-limp" fall.
-
Broad Formulation Compatibility: Compatible with cationic, anionic, and non-ionic surfactants in shampoos, conditioners, masks, and colorants; recommended post-addition below 45℃ to avoid demulsification.
-
Long-Lasting Softness: Uniform silicone deposition maintains softness after repeated washing, without yellowing or buildup—surpassing the short-term softening effect of traditional cationic polymers (e.g., JR-400).
Application Penetration: From Shampoos to Color Protection
IOTA 95099 covers hair care scenarios doubly sensitive to "repair + combability":
-
Shampoos: Especially 2-in-1 shampoos, 0.5-1.5% addition imparts conditioning during washing, cutting wet-combing resistance by 40-60%.
-
Conditioners/Masks: 1.0-2.0% addition as core conditioning agent for deep repair of damaged hair, lifting elasticity and shine.
-
Hair Colorants: 0.5-1.0% addition protects hair during coloring, reduces pigment loss, and enhances post-color vibrancy and longevity.
-
Styling Aids: 0.2-0.5% addition improves combability and shine of gels/waxes, reducing "dry-stiff" feel.
IOTA Technical Guide: Cool-Process Post-Add, Avoid Demulsification
-
Addition Timing: Strongly recommended at the final stage, below 45℃, to prevent cationic emulsifier hydrolysis or silicone demulsification from high heat.
-
Dilution Dispersion: Add directly to water phase or finished emulsion base; low-speed stir (300-500rpm) for 10-15min suffices for uniform dispersion—no high-shear homogenization (risk of demulsification).
-
Formulation Compatibility: Compatible with various surfactants; avoid direct mixing with strong anionic polymers (e.g., high-conc Carbomer)—disperse in water phase or emulsion base first.
-
Red Lines: 25kg/200kg plastic drum, non-haz; moisture-proof, no acid/alkali, sun-proof; reseal strictly after use; 12 months shelf life at room temp sealed.
-
Incompatibilities: Avoid prolonged heating >60℃; avoid direct mixing with strong oxidants or strong anionic substances; avoid freezing (demulsification irreversible).
Industry experts note that as the hair care trend converges on "color/perm freedom" and "hair health," cationic amino silicone emulsions are evolving from "simple softeners" to "multi-functional platforms for repair-conditioning-color protection." IOTA 95099, with its "amino core-repair + cationic locking + high-stability emulsion" combination,
fills the domestic mass-production gap for high-stability cationic silicone emulsions in damaged hair repair and wet-combing improvement, providing formulators a reliable tool to optimize hair care formulas and shorten R&D cycles. This confirms domestic hair conditioning agents are advancing steadily along "molecular design → emulsification process → scenario validation," with growing say in damaged hair repair and combing performance enhancement technologies.
