Product Overview
PEG-12 Polydimethicone is a high-performance polyether-modified polyorganosiloxane surfactant. It is grafted onto the polydimethicone backbone through ethoxylated hydrophilic groups, giving it excellent amphiphilic properties. This product has both the smoothness of silicone and the water solubility of polyether. It can be used as an efficient emulsifier, stabilizer and skin feel regulator, and is widely used in personal care and daily chemical formulation systems.
Core Features and Benefits
Excellent Surface Activity
Non-ionic structure ensures compatibility with various raw materials (including cationic/anionic systems), significantly reduces surface tension, and improves system wettability and spreadability.
Moderate hydrophilic-lipophilic balance (HLB) value can stabilize water-in-oil (O/W) and oil-in-water (W/O) emulsion systems.
Skin Feel and Function Enhancement
Gives the formula a silky smooth touch while maintaining skin permeability, avoiding the heavy and stuffy feeling of traditional silicone oil products.
Enhances foam stability, suitable for cleansing and bathing products that require rich foam.
Multi-functional integration
Film-forming aid: synergizes with high molecular polymers (such as K-30, VA-64) to form a transparent and flexible film layer, improving the gloss and durability of styling products (gel water).
Penetration promotion: assists the penetration of active ingredients and prolongs the action time of moisturizing and functional ingredients.
Antistatic property: eliminates static electricity on hair and fabrics, and improves combing smoothness.
Safe and gentle
Extremely low skin irritation, suitable for sensitive skin and infant care products.
Easy to biodegrade, in line with the trend of environmentally friendly formulas.
Typical application areas and formula recommendations
1. Hair styling products (gel water/mousse)
Function: As a film-forming agent emulsification carrier, it improves the flexibility and gloss of the film layer.
Compatibility: Compound with PVP/VA copolymers (such as VA-64) and acrylate polymers (such as K-30) to prepare a transparent gel system, with an addition amount of 2-5%.
Effect: Reduce the stickiness of hair and enhance the durability of styling.
2. Cleansing and skin care products (facial cleansers/creams)
Function: As an emulsifier and skin feel regulator, it improves the fineness and skin feel of foam.
Recommended dosage: 1-3%, which can replace some traditional silicone oils and improve the freshness of the product.
Synergistic enhancement: compounded with amino acid surfactants to make mild cleansers, and compounded with oil ingredients to make smooth creams.
3. Aerosols and plasticizers
Foam stabilization: used as a foam structure stabilizer in shaving foam or sunscreen spray.
Resin modification: used as a silicone plasticizer to improve the flexibility and weather resistance of plastics or coatings.
Formula application example
Transparent gel water formula
Technical points:
Add raw materials in sequence at room temperature, no high-temperature emulsification is required, and the production process is simplified.
The film hardness and glossiness can be controlled by adjusting the ratio of polymer to siloxane.
Safety and storage
Avoid contact with eyes. If contact occurs accidentally, rinse with clean water immediately.
Store in a cool and dry place, avoid freezing.
Shelf life: Stable for 24 months in unopened state.
Conclusion
PEG-12 polydimethylsiloxane has become the preferred raw material for balancing performance and skin feel in modern daily chemical formulas due to its unique molecular design and versatility. By flexibly adjusting the compatibility system, it can meet the needs of different dosage forms and help brands create innovative products that have both efficacy and pleasant experience.
