Vanishing cream is an example of

Options

A. Solution
B. Foam
C. Lyophilic solution
D. Emulsion

Answer

To determine what vanishing cream is an example of, we can follow these steps:

### Step 1: Understand the Composition of Vanishing Cream
Vanishing cream is a type of cream or ointment that is designed to leave no visible traces when applied to the skin. This characteristic suggests that it has a specific formulation that allows it to blend well with the skin.

**Hint:** Consider the properties of vanishing cream and what makes it different from other creams.

### Step 2: Identify the Type of Mixture
Vanishing cream is primarily composed of oil and water. The fact that it can be applied smoothly and disappears upon application indicates that it is likely an emulsion. Emulsions are mixtures of two immiscible liquids (like oil and water) where one is dispersed in the other.

**Hint:** Recall the definitions of different types of mixtures, especially emulsions.

### Step 3: Determine the Type of Emulsion
In the case of vanishing cream, since it contains oil dispersed in water, it is classified as an oil-in-water (O/W) emulsion. This is important because it helps in understanding how the cream interacts with the skin and its overall effectiveness.

**Hint:** Think about how emulsions are categorized based on the continuous and dispersed phases.

### Step 4: Conclusion
Based on the understanding that vanishing cream is an oil-in-water emulsion, we can conclude that it is indeed an example of an emulsion.

**Hint:** Review the characteristics of emulsions to reinforce your understanding.

### Final Answer
Vanishing cream is an example of an emulsion, specifically an oil-in-water emulsion.
