Industry Background
Traditional silicone-based conditioning agents in shampoos typically use a "polymerize-then-emulsify" process, resulting in larger particle sizes (usually >300nm) and thick film formation. While improving smoothness, this often causes "slippery residue" and "post-wash hair flattening," a core pain point in high-end shampoo formulations.
Technical Breakthrough & Product Implementation
Hony leverages its domestically pioneered "polymerization-emulsification integrated technology", adopting a disruptive "polymerize-while-emulsify" process:
· Precise particle control: Synchronized reaction-emulsification stabilizes silicone particle size at ~100nm (only 1/3 of traditional processes).
· Ultra-thin film formation: Nano-scale particles create a 0.1μm ultra-thin transparent film on hair, evenly covering cuticle gaps to enhance smoothness while avoiding heavy buildup.
Case: High-End Shampoo Upgrade
A leading brand aimed to develop a "high-conditioning, non-heavy" premium shampoo targeting "oily hair + lightweight volume" users.
Hony’s solution: Replaced traditional silicone with core product Hony 101A (100nm silicone emulsion).
Performance Data (Traditional vs. Hony 101A)
Test Item | Traditional Silicone (350nm) | Hony 101A (100nm) | Improvement | Testing Method |
Average Particle Size | 320-380nm | 95-110nm | ↓66% | Malvern Mastersizer 3000 laser granulometer |

Sensory Evaluation (n=100 Professional Salon Users)
Evaluation Dimension | Traditional Formula | Hony 101A Formula | Satisfaction Improvement |
Wet Hair Softness | 3.2/5 | 4.5/5 | ↑40.6% |
Dry Hair Lightness | 3.0/5 | 4.3/5 | ↑43.3% |
No Flattening | 2.8/5 | 4.1/5 | ↑46.4% |
Slippery Residue | 4.0/5 (high) | 2.2/5 (low) | ↓45.0% |
Formulation Compatibility & Irritation Testing
· Anti-dandruff agent optimization: Reduced pyrithione zinc (ZPT) from 1.0% to 0.8% while maintaining:
▶ Antibacterial rate: 98.5% (vs. 98.7% in original, ASTM E2149 compliant).
▶ Foam height: 180mm (equivalent to original 185mm).
· Skin irritation: Patch test (n=200) showed irritation rate dropped from 8.5% (original) to 3.0% (Hony 101A, p<0.05, statistically significant).
Testing Methods
1. Particle size: Laser granulometer (D50) after 5-min ultrasonic dispersion.
2. Comb resistance: Peak force measured on 10cm hair bundles (post-wash wet state).
3. Volume: Pressure-volume curve analysis of dry hair bundles.
4. Residue: UV spectrophotometry of fluorescently labeled silicone on scalp simulators.
All data verified by SGS, confirming Hony 101A resolves traditional silicone’s "heavy deposition" issue while maintaining conditioning, offering a superior technical path for high-end hair care.
