[1] [2] Cosmetic products are substances intended for human cleansing, beautifying and promoting an enhanced appearance without altering the body's structure or functions. [3]
The intent of Standard ISO 22715 is to specify how cosmetic products should be packaged and labeled to maintain a certain level of standards within the cosmetic industry. This standard applies to cosmetic products whether the product is sold or given away. It is one of 26 published standards that are devoted to the cosmetic industry sector. [1]

Sonication is the act of applying sound energy to agitate particles in a sample, for various purposes such as the extraction of multiple compounds from plants, microalgae and seaweeds. [1] Ultrasonic frequencies (> 20 kHz) are usually used, leading to the process also being known as ultrasonication or ultra-sonication .
Sound power or acoustic power is the rate at which sound energy is emitted, reflected, transmitted or received, per unit time. [1] It is defined [2] as "through a surface, the product of the sound pressure, and the component of the particle velocity, at a point on the surface in the direction normal to the surface, integrated over that surface."
However, this range is an average and will slightly change from individual to individual. Sound waves that have frequencies below 16 Hz are called infrasonic and those above 20 kHz are called ultrasonic. Sound is a mechanical wave and as such consists physically in oscillatory elastic compression and in oscillatory displacement of a fluid.
