Active Ingredient: Salicylic Acid 0.5% Inactive Ingredients: Water ●
TL;DR. This ingredient is a keratolytic exfoliant and OTC acne it. At the listed 0.5% level, it helps loosen pore buildup and reduce visible comedones.
What does Active Ingredient: Salicylic Acid 0.5% Inactive Ingredients: Water do in a cosmetic formula?
This ingredient is a keratolytic exfoliant and OTC acne it. At the listed 0.5% level, it helps loosen pore buildup and reduce visible comedones.
Is Active Ingredient: Salicylic Acid 0.5% Inactive Ingredients: Water clean?
Clean-beauty frameworks generally allow it, but treat it as a biologically it exfoliant rather than a neutral filler. The main watchpoint is irritation potential, especially in low-pH leave-on formulas or on already sensitized skin.
Is Active Ingredient: Salicylic Acid 0.5% Inactive Ingredients: Water sustainable?
This compound is usually made synthetically, often from petrochemical phenol and carbon dioxide, although bio-based routes exist. It is readily biodegradable and has low expected bioaccumulation in typical cosmetic use.
Is Active Ingredient: Salicylic Acid 0.5% Inactive Ingredients: Water COSMOS-approved?
It is permitted under COSMOS-natural and COSMOS-organic when it meets the standard’s allowed-use and concentration limits. From a Green Chemistry view, it scores well on biodegradability but less strongly on renewable sourcing in most commercial supply chains.
How does Active Ingredient: Salicylic Acid 0.5% Inactive Ingredients: Water work chemically?
The molecule is a small aromatic hydroxy carboxylic acid with more oil affinity than many water-soluble exfoliating acids, which supports activity in pore-rich, sebum-prone areas. At 0.5%, it is at the low end of common OTC acne use, and performance depends strongly on final pH, with more free acid present around pH 3 to 4.
