Which ingredient is commonly used as a preservative in PCPs?

it can be concluded that 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. These results reveal that phenoxyethanol was found present in 66% of the skincare products and 71% of make-up products examined this study. The second most dominant preservative used is sodium benzoate (36%) and followed by potassium sorbate (33.3%).

Which of the following fragrances is considered a weak allergen but found frequently in PCPs?

Furthermore, the most frequently identified fragrances were limonene (73.33%), linalool (69.17.5%), coumarin (40%), and hexyl cinnamal (38.33%), which are weak allergens. However the most fragrances, that considered a weak allergen but found frequently in PCPs, is limonene.

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

These chemicals are discharged into the environment through direct discharge from industries, hospitals, urban/municipal waste, and inefficient wastewater treatment systems. Previously chemicals in PCPs have not been considered harmful, and their effect on water, humans and the environment have not been investigated. However, 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.

What percentage of skin care products examined contained fragrances?

Notably, limonene frequently occurs in rinse-off products (90.5%) while linalool occurs mostly in skin care products (68.5%). This is because limonene also acts as a solvent to enhance the cleaning properties of a product.

What are the potential health risks associated with chemicals in PCPs as mentioned in the study?

In the past, these chemicals were commonly found in PCPs such as soaps, toothpastes, and detergents, but have been banned due to issues of endocrine disruption and antimicrobial resistance. In this context, it is highly likely that triclosan and triclocarban are still used as preservatives in these but excluded from the ingredient lists of PCPs investigated in this study
