Description
A potassium salt of Lactic acid. Potassium lactate has been added to vegetable tanned leather as an acid buffer and as a scavenger for Sulfur dioxide. Its effectiveness is questionable. Some treatments have resulted in a white eflorescence on the surface of the leather that is thought to be due to lactic acid or lactate salts (Gottleib 1982). Applications of potassium lactate to suede or deteriorated leathers (Red rot) can cause blackening (Roberts and Etherington 1982).
