Natural Soap Sweats

FYI

Did You Know......Natural & Organic Soap sweat??



Commercial soap bars have a number of chemicals to prevent this natural occurrence, and generally have most of the naturally occurring glycerin removed.



Sweating is simply a phenomenon that happens between moisture and a humectant (the substance that preserves moisture), in this case, the humectant is glycerin.


Glycerin in soap is a natural by-product of saponification and sometimes can be added as a moisturising agent. Humectants attract/absorb moisture from the air.

Glycerin in soap attracts the moisture from the air which form on the surface of the soaps - this is so-called soap ‘sweating’.



At first, soap sweating looks like frost, and upon closer inspection, small water droplets are visibly covering the surface of your soap. As it is not coming from inside the soap, but rather moisture from the air being attracted by the glycerin in the soap. The more humid the environment, the more likely the glycerin will attract moisture on to the surface of your soaps.


Sweating can also happen with soap or shampoo bars which contain ingredients that act as natural humectants like honey or castor bean oil.



Soap sweating is not an alarming phenomenon, as it is natural for the glycerine to attract moisture from the air.

Glycerin is known to be beneficial for the skin. The theory is that when you wash with glycerin soap, a thin layer of glycerin is left behind, which will then draw moisture from the air, onto your skin, thus moisturizing it more.



If you purchase a bar of 'Natural' or 'Organic' soap, leave it out on a humid day. If it sweats, YAY! That means it's a healthy bar.
