Science
Mechanism of Action
This ingredient functions by breaking hydrogen bonds within protein structures, which increases the solubility of non-polar amino acid side chains and reduces hydrophobic interactions, ultimately leading to protein unfolding. The precise mechanism by which it might confer anecdotal skincare benefits like hydration or barrier support at safe cosmetic concentrations is not thoroughly detailed in scientific literature.

Safety
Safety Profile
Guanidine hydrochloride is classified as harmful if ingested or inhaled, and is known to cause significant irritation to both skin and eyes. Repeated or prolonged exposure can lead to severe skin irritation, characterized by redness, swelling, vesicles, scaling, thickening, and potential ulceration. It can also cause moderate eye irritation, leading to inflammation and conjunctivitis. OSHA considers this substance hazardous.

Verdict
Due to its classification as a hazardous substance with high irritancy potential and the absence of thoroughly detailed or clinically supported skincare benefits at safe cosmetic concentrations, Guanidine HCL is not recommended for cosmetic formulations.
