Physical & Chemical Characteristics
- Appearance: White to slightly yellow powder
- Odor: Slight characteristic odor
- Solubility: Easily soluble in water
- Aqueous solution:
Colorless
Transparent to translucent
Transparency affected by concentration and temperature
Solution Behavior
Higher concentration → Increased opacity
As concentration rises, micelle formation increases, which can make the solution appear more turbid.
Lower temperature → Increased opacity
Reduced temperature can decrease solubility and micelle clarity, leading to cloudiness.
Hygroscopicity
PDS easily absorbs moisture from air and tends to agglomerate (cake), although the formed lumps are generally soft and not very hard.
Functional Properties
As a typical anionic surfactant, PDS provides:
- Strong detergency
- Excellent foaming ability
- Good emulsifying and dispersing performance
- Protein denaturation capability (similar to SDS)
Applications
