Disincrustation solutions are formulated to be:

Disincrustation solutions are specifically formulated to be alkaline. The alkaline properties are essential because they help to break down fatty deposits and oils in the skin, making it easier to extract impurities and perform deep cleansing. The use of an alkaline solution is beneficial during facial treatments, particularly in preparations for galvanic treatments that aim to soften and emulsify sebum.

In contrast, acidic solutions serve different purposes and are often used for exfoliation or toning; thus, they would not effectively dislodge impurities like an alkaline solution. Neutral solutions are balancing and would not have the potent effect necessary for disincrustation. Bacterial formulations do not relate directly to disincrustation but rather pertain to antiseptic practices, which also do not align with the main goal of disincrustation. The choice of an alkaline solution is crucial for achieving optimal results in skin treatments focused on cleansing and preparing the skin.
