What Is Gluconic Acid, and Where Does It Occur?
Before we dive into the details, let’s introduce the chemical. Gluconic acid is a type of organic acid that’s created when glucose is oxidized. It’s found in small amounts in some fruits and honey. Gluconic acid is also produced as a by-product of fermentation, so it occurs naturally in wine.
This compound has a wide range of uses, from cleaning (to dissolve mineral deposits) to food production (as an acidity regulator). When it’s dissolved in water, it forms gluconate ions, which are known to have a number of benefits for the skin.
How Does Gluconic Acid Benefit the Skin?
Gluconic acid is a popular ingredient in skincare products, and for good reason. When added to cosmetics, it can:
- Exfoliate the skin without irritating it.
- Indirectly improve the cell turnover rate, which means that new skin cells are generated more quickly.
- Help to brighten the skin and remove discoloration.
- Regulate the pH levels of cosmetics, making them more acidic (which is what our skin needs).
Gluconic acid works as a gentle exfoliant, helping to remove dead skin cells and revealing the new, healthy skin cells beneath. This process is important for keeping the skin looking bright and clear. Additionally, gluconic acid can help to even out the skin tone by reducing discoloration.
Another benefit of gluconic acid is that it can help to regulate the pH levels of cosmetics. Our skin is naturally slightly acidic, with a pH level of around. This acidic environment is important for maintaining the skin’s barrier function. When the pH level of our skin is off, it can lead to dryness, irritation, and inflammation.
These properties make gluconic acid an excellent addition to any skincare routine, particularly if you’re looking for a gentle exfoliant or want to brighten your complexion. If you’re curious what kinds of products contain it, read on!
Beauty Products Containing Gluconic Acid
As you’ve probably guessed by now, gluconic acid is commonly used in skincare products. It can be found in peels, cleansers, toners, serums, and masks. Peeling lotions are another type of product that often contains gluconic acid, as this ingredient can help to slough off dead skin cells.
You might also encounter it in balancing mists, facial cleansers, and acne creams. The sky is the limit when it comes to gluconic acid, so keep your eyes peeled for this ingredient the next time you’re browsing your favorite beauty products!
If you read ingredient lists carefully, you may have noticed gluconic acid listed under a few different names. It can also be added in the form of glucono delta-lactone or gluconolactone. These are esters of gluconic acid, which means that they’re more easily absorbed by the skin. The maximum safe concentration of the acid in cosmetics is 1-5%.
Other Uses of Gluconic Acid
As we mentioned earlier, gluconic acid has a wide range of uses. It’s often used in food production as an acidity regulator (E574), and it can also be found in cleaning products. This compound is known for its ability to dissolve mineral deposits, making it an effective way to clean hard surfaces.
Gluconic acid is also used in building and construction. It can be added to concrete to increase its strength, and it’s often used as a rust inhibitor. Besides, it can be used to synthesize other useful compounds:
- calcium gluconate – used to treat burns from hydrofluoric acid;
- zinc gluconate – used to neuter male dogs;
- quinine gluconate – used to treat malaria.
As you can see, gluconic acid is a versatile and fascinating compound with many uses. It’s no wonder that it’s become such a popular ingredient in skincare products.
