Which of the following fragrances is considered a weak allergen but found frequently in PCPs?
|
Limonene |
|
It is illustrated in Table 2 that 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. 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. These results are comparable with the study conducted by Panico et.

What is the primary purpose of Process Analytical Technology (PAT)?
|
To monitor process parameters and product quality attributes. |
|
It is a mechanism to design, analyse and control manufacturing processes through on-line, in-line, at-line and off-line configurations for monitoring Critical Quality Attributes (CQAs).

Which technology is often combined with reliable in-line sensors to enhance PAT systems?
|
Multivariate Statistical Methods (MSMs). |
|
PAT systems include a combination of reliable in-line sensors, spectroscopic instruments and Multivariate Statistical Methods (MSMs) to provide informative knowledge for quality assessment of powdered and granule products. Nevertheless, monitoring programs of advanced manufacturing processes based on PAT systems typically provide large sets of data which are complex to interpret.
