M550 is a high-efficiency cationic conditioning polymer based on Polyquaternium-7, specially developed for cost-effective yet high-performance personal care formulations. As a classic quaternized copolymer, it balances excellent conditioning, anti-static, anti-frizz and irritation-mitigating properties, making it a versatile choice for daily hair and skin care products. It can rapidly adsorb onto hair and skin surfaces, forming a smooth, non-greasy protective film, effectively improving wet and dry combability, reducing tangling and breakage, while mitigating the irritation caused by surfactants in cleansing systems. With outstanding compatibility and stability, it is widely used in mass-market to mid-range personal care products.

Core Benefits
- Cost-effective Conditioning: Delivers reliable hair conditioning performance at a competitive cost, significantly improving both wet and dry combability, reducing tangling and breakage in daily shampoos and conditioners.
- Anti-static & Anti-frizz: Effectively neutralizes static electricity, eliminates hair flyaways and frizz caused by dry environments, leaving hair smooth, docile and easy to manage.
- Mild & Skin-friendly: Reduces the irritation of surfactants in cleansing products, enhances skin smoothness and comfort after washing, suitable for sensitive scalps and daily body washes.
- High Formulation Stability: Shows no precipitation or delamination in various formula systems, compatible with both transparent and opaque formulations, including clear shampoos and pearlescent body washes.
- Lightweight Film-forming: Forms a thin, breathable protective film on hair and skin without greasiness or build-up, suitable for frequent-use personal care products.
3. Application
- Recommended Dosage: 2.0-6.0% (based on total formulation weight, adjustable according to formula needs)
- Usage Recommendation: Add in the later stage of product preparation at a temperature below 60°C, stir evenly at low speed to ensure uniform dispersion, to avoid affecting its cationic activity and conditioning performance under high temperature.
- Formula Application:
- Hair care: Daily shampoos, conditioners, hair masks, perm and hair dye products
- Skin care: Body washes, facial cleansers, hand sanitizers and other mild cleansing products
4. Packaging and Storage
- Packaging: 50 kg/barrel (custom small-sized packaging available upon request)
- Storage Conditions: Store in a ventilated, cool and dry place, away from direct sunlight and high temperature (above 35°C). Do not mix with strong acids, strong alkalis or oxidants.
- Shelf Life: 12 months under proper sealed storage conditions. After opening, use within 3 months and keep tightly sealed when not in use to prevent contamination.
