Which of the following statements about the types of soaps is/are TRUE?
1. Transparent soaps are made by dissolving the soap in ethanol and then evaporating the excess solvent.
2. Shaving soaps contain fillers like sodium rosinate, sodium silicate, borax and sodium carbonate.
3. Soap chips are made by running a thin sheet of melted soap onto a cool cylinder and scraping off the soaps in small broken pieces.
Choose the correct answer from the options given below:
Soap Types: Statement Analysis
We need to evaluate the truthfulness of the three statements regarding different types of soaps.
Statement 1: Transparent Soaps
This statement is TRUE. Transparent soaps are manufactured by dissolving standard soap in ethanol. The ethanol acts as a solvent, removing water and impurities. As the ethanol evaporates, it leaves behind a clear soap base.
Statement 2: Shaving Soaps
This statement is FALSE. While shaving soaps aim for a smooth lather and often contain glycerin for moisturizing properties, the fillers listed (sodium rosinate, sodium silicate, borax, sodium carbonate) are not typical components. These substances are more commonly found in laundry soaps or detergents for enhanced cleaning or alkalinity, not specifically in shaving soaps.
Statement 3: Soap Chips
This statement is TRUE. Soap chips (or flakes) are produced using a specific industrial method. A thin layer of molten soap is spread onto a cooled, rotating cylinder. The soap solidifies quickly and is then scraped off the cylinder, resulting in small, thin pieces known as chips or flakes.
Conclusion
Based on the analysis, statements 1 and 3 are true, while statement 2 is false. Therefore, the correct option includes statements 1 and 3 only.
