The detail on SpecWhite PLGA Glycolic Acid
from SpecChem
SpecWhite® PLGA – Glycolic acid (hydroacetic acid or hydroxyacetic acid); with chemical formula C2H4O3 , is the smallest α-hydroxy acid (AHA).
This colorless, odorless, and hygroscopic crystalline solid is highly soluble in water. It is used in various skin-care products.
Glycolic acid is slightly stronger than acetic acid due to the electron-withdrawing power of the terminal hydroxyl group. The carboxylate group can coordinate to metal ions forming coordination complexes. Of particular note are the complexes with Pb2+ and Cu2+ which are significantly stronger than complexes with other carboxylic acids. This indicates that the hydroxyl group is involved in complex formation, possibly with the loss of its proton.
Cosmetic Applications of Glycolic Acid
Due to its capability to penetrate skin, Glycolic acid finds applications in skin care products, most often as a chemical peel. Physician-strength peels can have a pH as low as 0.6 (strong enough to completely keratolyze the epidermis), while acidities for home peels can be as low as 2.5. Once applied, Glycolic acid reacts with the upper layer of the epidermis, weakening the binding properties of the lipids that hold the dead skin cells together. This allows the stratum corneum to be exfoliated, exposing live skin cells.
Other applications of Glycolic Acid
- Used in food processing as a flavoring agent and as a preservative
- Used in the pharmaceutical industry as a skin care agent
- Used in adhesives and plastics,
- Glycolic acid is often included in emulsion polymers, solvents and additives for ink and paint in order to improve flow properties and impart gloss
It is used in surface treatment products that increase the coefficient of friction on tile flooring. It is the active ingredient in the household cleaning liquid Pine-Sol.
