Which ingredient is commonly used as a preservative in PCPs?

According to Table 3, the most common preservative among PCPs available in South Africa that were examined for this investigation was Phenoxyethanol (47.8%).

Phenoxyethanol is a substance with antimicrobial properties. Its molecule contains both polar and non-polar parts, allowing it to dissolve in both water and oil, thus protecting products with mixed phases from fungi and bacteria.

What does the term 'emerging pollutants' refer to in the context of the study?

The pollutants that are produced are eliminated by natural plants and organisms, whether underground or in water, but there is no way that these pollutants can be eliminated in a short period of time.

Pollutants, whether they are human-caused water pollutants such as garbage, all take their own time to decompose biologically, or even if they are decomposed using chemicals to shorten the time.

According to the study, which substance is toxic to aquatic life and can affect fertility?

In this reseach , they reported that alpha-isomethyl ionone is toxic to aquatic life with long lasting effects that we sholud concern about.

Alpha-isomethyl ionone is a man-made fragrance used in many personal care products. Even though it smells nice, it is harmful to fish and other water animals and can stay in the environment for a long time. It can get into rivers and oceans through wastewater and cause long-term damage. Because of this, some countries have rules about using it

Based on the study, which regulatory action is recommended due to the detection of harmful ingredients in PCPs despite their ban?

The findings of this study emphasize the urgent need for tighter regulations on labeling, safety testing, and the management of hazardous substances in PCPs in South Africa.

Testing ingredients from the industrial system and preventing them from being part of it is the most sustainable prevention and solution because it is part of the production that will release the product to the consumer.
