Poly(propylene glycol)
CAS NO. 25322-69-4
Alias：POLYPROPYLENE GLYCOL, DIOL TYPE, 1000;POLYPROPYLENE GLYCOL, DIOL TYPE, 2,000
Molecular formula: CH4
Molecular weight：16.04246
Structural formula：
1.Performance and use
Polypropylene glycol is a high molecular weight substance widely used in chemical, pharmaceutical, food, plastic and other fields. It has the characteristics of high viscosity, high consistency and strong moisturizing performance, and is widely used to manufacture various liquid products, such as shampoo, conditioner, face cream, lotion, etc. In addition, polypropylene glycol can also be used to adjust viscosity, increase solubility, and reduce membrane pressure sensitivity.
2.Technical indicators
| Appearance (25℃) | Colorless viscous liquid |
| Hydroxyl value (mgKOH/g) | 34~42 |
| Acid value (mgKOH/g) | ≤0.05 |
| Water content (% m/m) | ≤0.05 |
| Colour (Pt-Co) | ≤20 |
| PH value (1% aqueous solution) | 5.0~7.0 |
3. Packaging and storage
Packaging specification:25kg/drum.
According to regulations, polypropylene glycol should be stored indoors in a cool, dry place, away from direct sunlight and high temperature, humid environment. Meanwhile, the packaging container of polypropylene glycol should be sealed and stored to prevent inversion. The storage period should generally not exceed 6 months, and expired polypropylene glycol cannot be used again.
4. Safety protection
When using polypropylene glycol, protective equipment such as masks and gloves should be worn to prevent harm to the human body during inhalation, splashing, and other operations. Direct contact with skin, eyes, etc. should be avoided. In case of accidental contact, rinse immediately with plenty of water. If discomfort occurs, seek medical attention immediately.
