In wig manufacturing, human-hair and synthetic weft finishing, full-wig care, and film/special-effect hairpiece treatment, formulators are often stuck because "softness and slip rarely come together, immersion emulsion separates and oils off, ionic conflict arises with dyeing or care systems, and working concentration is hard to control". Untreated wigs feel dry and tangled with high comb drag; post-dye human hair becomes rougher. Ordinary oily shine oils add gloss but feel sticky, trap dust, and leave uneven residue after washing; nonionic or anionic silicone emulsions show weak electrostatic adsorption on negatively charged protein/synthetic surfaces, so the desired "supple, quick-comb, non-harsh" handle is not assured; some high-solid silicone emulsions have poor centrifugal stability, causing oil float and uneven pickup in bulk immersion. With premium wigs, extension wefts, cosplay wigs, and medical/legal hairpieces demanding "cationic adsorption, O/W dilutable, low-friction softness, batch-immersion stability", finding a "functional polysiloxane, cationic, O/W homogeneous, centrifugally stable, wig-dedicated" shiny oil has become a key issue for hair-product finishing. Addressing this, Anhui IOTA Silicone Oil Co., Ltd. officially launches Wig Shiny Oil IOTA 2615. Characterized by "functional polysiloxane O/W emulsion; uniform milky emulsion; pH 6–7; content 25±2%; cationic; stability 15 min at 3000 rpm without stratification; suitable for wig processing, immersion working liquor reference 2–5%; 50kg plastic drum or customized; sealed storage 5–30℃, avoid high temperature and freezing in transport and storage; 6-month shelf life; non-combustible non-hazardous", backed by "cationic polar adsorption + homogeneous O/W fine emulsion + siloxane low-friction film + high centrifugal stability", it serves as the "comb-smoothing choice" for wig finishing, achieving the leap from "dry tangling, silicone oil-off" to "cationic silicone hair-soft, uniform immersion new comb". System Positioning: Cationic Functional Polysiloxane O/W vs. Nonionic/Anionic Emulsion/Oily Shine IOTA 2615 belongs to cationic functional polysiloxane oil-in-water emulsion, distinct from nonionic silicone emulsion, anionic silicone emulsion, and pure oily shine oil. Nonionic emulsion is broadly compatible but adsorbs weakly on negatively charged hair/protein fibers, so wig softness lacks "cling"; anionic emulsion easily neutralizes with cationic dyeing auxiliaries or hair-conditioning agents and breaks; pure oily shine adds gloss but feels sticky, gathers dust, leaves uneven wash residue, and is inconvenient for waterborne bulk immersion. IOTA 2615 uses cationic emulsification plus functional polysiloxane to attract deposit on hair surfaces by electrostatic/polar interaction, while the O/W water phase enables low-concentration immersion, easy rinsing, and low odor for scale finishing. Molecular Architecture: Functional Polysiloxane + Cationic O/W + Low-Friction Soft Film The core design of IOTA 2615 comes from a cationic siloxane water-emulsion structure:

• Functional Polysiloxane Backbone： A polysiloxane flexible backbone supplies low surface energy, low friction, and soft resilient handle; "functional" means polar or cationically adsorbable groups on the main/side chain (exact modifying family by COA; not assumed amino, quaternary, or polyether), so the silicone not only spreads physically but also interacts with polar sites on hair surface, improving softness and slip durability.
• Cationic O/W Emulsification： The cationic emulsifier system disperses polysiloxane into a uniform milky O/W emulsion with overall positive tendency; this attracts deposition on negatively charged human-keratin surfaces and some treated synthetic layers, reducing loss during immersion. pH 6–7 near-neutral lowers risk to post-dyed shade and scalp contact (sensitivity by end-product evaluation).
• Fine Homogeneous, Low-Stratification： Supplied stability is 15 min at 3000 rpm without stratification, reflecting narrow particle distribution and homogeneous emulsification; in wig immersion tanks the O/W stays uniform, with little creaming or oiling, so upper/lower bath concentration drift is small and whole weft lots absorb consistently.
• Low-Friction Softening Film： The siloxane chain forms a very thin lubricating film on single filaments, lowering friction between filaments and between hair and comb teeth; together with cationic adsorption it delivers "soft but not oily, slippery but not greasy" comb feel and reduces dry/wet comb drag and breakage.

Performance Leap: From "Dry Tangle" to "Cationic Uniform Comb New Comb" Introducing IOTA 2615 brings improvements in wig finishing:

• Softness and Resilience： The polysiloxane flexible backbone improves bending resilience and fullness; human-hair wefts lose stiffness, synthetic fiber loses plastic feel. Supplied qualifies "improves softness" without fabricated softness numbers.
• Smooth Combing： The low-friction silicone film reduces dry/wet comb resistance; wigs are easier to wear, style, and maintain with less tangling. Supplied qualifies "smooth touch" without fabricated friction/comb-force values.
• Uniform Immersion： Cationic O/W plus centrifugal stability keeps a 2–5% working bath uniform; long wefts, hair curtains, and full wigs absorb evenly, reducing local oiling versus local dryness.
• Low-Tack, Less Dust： Compared with pure oily shine, the water-emulsion film is thinner, adds little weight, and feels non-sticky; actual anti-dust period depends on wearing environment and filament surface, by trial.
• Batch Stability： 50kg drum customizable, 5–30℃ sealed, 6 months, non-combustible non-hazardous, supporting safe turnover for wig factories, care workshops, and e-commerce refill lines.

Application Penetration: From Human-Hair Weft to Full Wig IOTA 2615 covers the whole wig finishing chain:

• Human-Hair Wig Finishing： Post-dye/perm wefts de-roughing and softening by immersion; improves supple touch for faded dry hair (not a claim to restore color or repair fracture).
• Synthetic/Blend Weft： High-temp fiber, low-temp fiber, Kanekalon and other synthetics for softness, reduced static tangling, and lower plastic gloss; specific fiber grades by sample trial.
• Full-Wig Factory Finish： Unified immersion, draining, and drying after mold release to standardize handle grade and reduce unit-to-unit variation; drying temperature by plant process and trial.
• Extension/Weft Care： Periodic immersion for hair pieces and extensions improves comb-through and wearing comfort; verify non-tack with extension glue and metal fixtures before use.
• Retail/Return Recondition： E-commerce and wig stores use light 2% immersion to re-soften returned wigs against transport roughness; severe tangling still needs mechanical combing, not higher dosage alone.

IOTA Technical Guide: 2–5% Immersion, Cationic Avoid Strong Anionic

• Working Liquor： Original emulsion content 25±2%, cationic O/W; wig immersion reference 2–5% calculated on original emulsion. Heavy dryness/tangling and long thick hair take the upper end; light reconditioning and full-wig refresh take the lower end. Hard water/high electrolyte may affect cationic stability; start with softened or deionized water, stir slowly, avoid prolonged high-shear.
• Immersion Process： Immerse wefts/wigs in working liquor until uniformly wetted, hold briefly for silicone deposit, drain, then air-dry or low-temperature dry per plant process; no supplied temperature/time curve is assumed. Post-dyed human hair should be small-batch tested for shade and handle first.
• Blending Caution： Cationic system should not be directly co-batched with strong anionic dyeing agents, strong anionic surfactants, or large amounts of carboxylate salts to avoid charge-neutralization breaking; if combined with other softeners, fixatives, or antistatics, run centrifugal/standing compatibility tests for stratification, oiling, and tack before scale-up.
• ⚠️ Taboo： Sealed storage 5–30℃; avoid high temperature (emulsion break, active degradation) and freezing (O/W freeze-breaking, particle coarsening) in transport and storage; reseal after use to prevent skinning and contamination. Non-combustible non-hazardous, yet manage as waterborne chemical; rinse skin with water after contact. Prepare working liquor for same-day use or set reconstituted storage by trial to avoid prolonged settling.
• Storage： 50kg plastic drum or customized; 5–30℃ sealed; avoid high heat and freezing; 6-month shelf life; non-combustible non-hazardous. Unlike IOTA 1318 (leather nonionic hydrophobic), IOTA 1325 (fabric cationic wash-durable), IOTA 2606 (fluoro-silicone anionic slick/anti-soil), IOTA 1302 (hydrogen nonionic breathable waterproof), IOTA 240 (high-temperature silicone emulsion), IOTA EMUL 872 (high-solid slightly anionic general release), IOTA 2615 is cationic functional polysiloxane wig O/W—1318 for leather surface, 1325 for fabric wash durability, 2606 for coating slick/anti-soil, 1302 for fiber/building breathable hydrophobic, 240 for hot lube, 872 for multi-line release, 2615 for wig soft-comb shine.

Industry Insight： The core value of wig silicone shiny oil lies in "functional polysiloxane for soft low-friction, cationic O/W for hair-surface uniform deposit, near-neutral pH for post-dye safety, centrifugal stability for bulk immersion without separation". IOTA 2615, with "functional polysiloxane O/W, uniform milky, pH 6–7, 25±2%, cationic, 3000 rpm 15 min no stratification, wig immersion 2–5%, 50kg drum, 5–30℃ avoid heat/freezing, 6 months, non-combustible non-hazardous" hard parameters, fills the cationic O/W dedicated node between nonionic weak adsorption, anionic easy-breaking, and oily sticky shine. For wig factories, weft suppliers, extension care, and e-commerce refill, it upgrades along "oily shine → nonionic silicone emulsion → cationic functional polysiloxane O/W", reducing tangling breakage and oil-off uniformity risk while raising integrated premium of softness, slip, and combing.
