Does Sodium Lactate exhibit keratolytic property?
Hi All,
We all know that lactic acid is a known keratolytic agent. And there are numerous literature written about it. But if I may ask, is this also true with sodium lactate? Does sodium lactate have the same keratolytic property as lactic acid? -

Sodium lactate, when added to water, will produce a basic solution due to the formation of the lactate salt. This is different from lactic acid, since adding lactic acid into water will produce an acidic solution, which is very good for keratolytic activity. If you are using sodium lactate, your product will be more of moisturizing rather than keratolytic.

I know this is an old thread, but I had a similar question about Ammonium Lactate. The keratolytic lotions, such as AmLactin and Lac Hydrin, advertise that they have 12% lactic acid but all have ammonium lactate in them. Does ammonium lactate have good keratolytic properties because it produces a more acidic solution when added to water?

Pretty sure that is in there only as a buffering additive, jvic. These organic acids work as keratolytic desquamators only in the acid pH range, as stated above.

AmLactin and LacHydrin lotions advertise lactic acid as the main AHA for their keratolytic properties so ammonium lactate is intended to be more than just a buffer. The pH of these lotions is about 4-4.5 and there are no other organic acids present.
