Hypothesis
The addition of ethyl alcohol to emulsions stabilized by cellulose derivatives will enhance their stability and rheological properties.
Conclusion
The study found that emulsions with ethyl alcohol remained stable for up to five months, while those without it broke within two days.
Supporting Evidence
- Emulsions with added ethanol showed no phase separation for up to five months.
- Emulsions without ethanol broke within two days after preparation.
- Rheological measurements indicated increased viscosity in the presence of ethanol.
Takeaway
This study shows that adding alcohol to certain mixtures can help keep them from separating, making them last longer.
Methodology
The emulsions were prepared using cellulose derivatives in a 70% ethanol solution, and their stability and rheological properties were measured over time.
Limitations
The study did not explore the long-term stability beyond five months or the effects of varying concentrations of cellulose derivatives.
