What percentage of the PCPs examined contained UV filters?
|
58% |
|
PCPs contain UV filters
|
PCPs contain UV filters in order to protect one’s skin from the harmful effects of UV light, which can potentially cause skin cancer and/or wrinkling. UV filters were used in 58% of the PCPs (Sebatane Sharon Mabitla Natsayi Chiwaye Michael O. Daramola )

Hair care products |
|
Personal care products (PCPs) comprise a wide range of chemicals employed in various products such as cleansers, toothpaste, sunscreens,make up and skincare
|
A total of 185 PCPs were examined, with 57% of these products classified as skincare, 32% as rinse-off products and 11% as make-up products. (Sebatane Sharon Mabitla Natsayi Chiwaye Michael O. Daramola )

Which ingredient is commonly used as a preservative in PCPs?
|
Phenoxyethanol |
|
phenoxyethanol was found in skincare products and make-up
|
Phenoxyethanol (47.8%) is the most dominant preservative used in PCPs found in South Africa as analysed in this study. In reference to Table 3 above, phenoxyethanol was found in 35 skincare products and also in 5 make-up products (Sebatane Sharon Mabitla Natsayi Chiwaye Michael O. Daramola )

What was the primary aim of the study discussed in the article?
|
To investigate the presence of toxic chemical ingredients in PCPs |
|
because PCPs are a component of many chemicals
|
ersonal Care Products (PCPs) contain a wide range of chemicals which cleanse or enhance one’s body appearance. These chemicals are continuously released into the environment, and if not properly regulated, they can be persistent, bioaccumulative and toxic in the environment.

Which of the following fragrances is considered a weak allergen but found frequently in PCPs?
|
Limonene |
|
limonene is found 73.3%
|
the most frequently identified fragrances were limonene (73.3%), linalool (69.2%), coumarin (40%), hexyl cinnamal (38.3%), benzyl alcohol (35%) and citral (28.3%). These fragrances are reportedly weak allergens this explains their high occurrence in most of the PCPs.

What does the term 'emerging pollutants' refer to in the context of the study?
|
Pollutants that have recently been discovered and may not degrade easily |
|
These chemicals are continuously released into the environment, and if not properly regulated, they can be persistent, bioaccumulative and toxic in the environment.
|
emerging evidence suggests that some accumulate in body tissues and negatively impact humans and animals, impacting the endocrine systems and the environment since they are continuously being released and may not degenerate easily the environment. The contaminants are thus called emerging pollutants.

|
Alpha-isomethyl ionone is harmful to the environment and restricted by regulatory bodies
|
These include harmful fragrances such alpha-isomethyl ionone and butylphenyl methylpropional, which were found to be present in
over 16% of the studied PCPs

What are the potential health risks associated with chemicals in PCPs as mentioned in the study?
|
Both 1 and 2 |
|
The great consumption of these products has led to their continuous release into the environment, which consequently threatens ecosystems and human health
|
The reported health risks associated with chemical ingredients in PCPs (such as ultraviolet (UV) filters, parabens, and phthalates) include
potential endocrine disruption and exhibition of estrogenic activity

What is the primary purpose of Process Analytical Technology (PAT)?
|
To monitor process parameters and product quality attributes. |
|
Process Analytical Technology (PAT) is a system that focuses on controlling and enhancing the understanding of a production process
|
PAT's primary goal is to measure critical process parameters (CPPs) that directly impact the essential quality attributes of active pharmaceutical ingredients (APIs).
