Product description

D-Glucono-1,5-Lactone (known by the abbreviation GLD; chemical formula C6H10O6)) is a polyhydroxy acid (PHA) that is found in its natural state (gluconic acid) in honey, royal jelly, fruit juices, wine, and various fermented products. It is considered the next generation of AHAs.

Gluconic acid is a glucose molecule in which the aldehyde function has been oxidized to an acidic function. Naturally bees do this with enzymes and in fermented products (wine, kombucha, etc.) this is done by microorganisms.

It is therefore a dry form of gluconic acid, which is obtained by removing water during the crystallisation process. When it is dissolved in water, a gluconic acid solution is formed.

In the food industry, it is a GRAS (Generally Regarded As Safe) ingredient.

In the cosmetic industry, it is used for its moisturizing effects on the skin, helping to smooth fine lines on the face. It is also used to gradually and continuously lower the pH in cosmetic products. It is also used in hair care - it helps to keep hair shiny and soft.

It is often combined with other preservatives to enhance the antimicrobial stability of finished products. It is ideally combined with preservatives whose effectiveness depends on the low pH of the product.
