Which of the following fragrances is considered a weak allergen but found frequently in PCPs?
|
|
|
The article identifies alpha-isomethyl ionone as a weak allergen, meaning it has lower sensitization potential compared to stronger allergens like butylphenyl methylpropional (lilial) or limonene. However, alpha-isomethyl ionone is frequently found in PCPs due to its widespread use in fragrances.

According to the study, which substance is toxic to aquatic life and can affect fertility?
|
Butylphenyl methylpropional |
|
The study identifies Butylphenyl Methylpropional (also known as lilial) as a toxic substance to aquatic life and one that can affect fertility. It is commonly used as a fragrance ingredient in PCPs and has been under increasing regulatory scrutiny in the EU due to its potential reproductive toxicity.

Based on the study, which regulatory action is recommended due to the detection of harmful ingredients in PCPs despite their ban?
|
More stringent regulations on product labelling and testing |
|
The study highlights that some banned or restricted substances (like Butylphenyl Methylpropional) were still found in PCPs. This suggests gaps in enforcement and leads to the recommendation for stricter regulations, especially in labelling transparency and product testing, to protect both consumers and the environment.

|
Both 1 and 2 |
|
The study reports that certain chemicals found in PCPs, such as UV filters and fragrance compounds, have been linked to endocrine disruption and estrogenic activity. These effects can interfere with hormone systems and may pose risks to reproductive health, development, and long-term hormonal balance in humans and wildlife.

What is the primary purpose of Process Analytical Technology (PAT)?
|
To monitor process parameters and product quality attributes. |
|
Process Analytical Technology (PAT) is a framework designed to monitor, control, and optimize manufacturing processes in real-time. It uses tools like sensors, multivariate data analysis, and process models to track critical process parameters (CPPs) and critical quality attributes (CQAs) — helping ensure consistent product quality and process efficiency.

What does data fusion primarily help improve in PAT systems?
|
Increase performance and robustness of models. |
|
In the context of PAT systems, data fusion involves combining data from multiple sensors to gain a more complete and accurate understanding of the process. This enhances the performance (accuracy, sensitivity) and robustness (reliability under varying conditions) of the analytical and predictive models used in process monitoring and control.

|
Increased financial services. |
|
The article explains that continuous processing of powdered and granule products has many advantages, like improving productivity, making product quality better, and helping the process run more smoothly. But it doesn’t mention anything about financial services. “Increased Financial Services” is not related to production, so it is not a real advantage listed in the study.

Which of the following is considered a Critical Quality Attribute (CQA) for powdered and granule products?
|
Particle size. |
|
In the article, particle size is described as an important Critical Quality Attribute (CQA) for powdered and granule products. This is because it affects how the powder flows, mixes, and dissolves. If the particles are too big or too small, the product might not work the way it should. So, particle size must be checked carefully to make sure the product is good and safe to use.
