Final answer:
Transparent cream cosmetics can suffer from faults such as phase separation, syneresis, microbial contamination, and changes in texture or color, which all affect product quality and user satisfaction.
Step-by-step explanation:
Transparent cream cosmetics can encounter several faults that affect their quality, performance, and consumer satisfaction. One common issue is phase separation, which occurs when the product separates into oil and water components.
This can lead to inconsistency in the application and reduce the effectiveness of the product. Another fault is syneresis, which is when liquid seeps out of the gel or cream, often caused by instability in the emulsion.
Additionally, microbes can contaminate cosmetics, leading to spoilage and possible harm to the user, which is why preservation is critical. Lastly, improper formulation or storage can result in changes in texture or color, which can make the product less appealing and affect performance.
