Sodium PCA

Today's Chemical:

Sodium PCA

EWG Skin Deep Hazard Score:


What is it:

Sodium PCA is short for sodium pyroglutamic acid.  It is the sodium salt of pyroglutamic acid, a derivative of the amino acid proline. Sodium PCA is considered to be a synthetic chemical.  It is used as a humectant and skin conditioner in cosmetic formulas.

What are its risks:

  • In the presence of certain chemicals and in heat and light, sodium PCA can break down and create carcinogenic nitrosamines. (Source)
  • No reproductive studies have been done on this ingredient.  It is unknown if it is a xenoestrogen.
  • When ingested in larger amounts, may have unknown effects on the brain. (Source)

Steph's Opinion:

I would consider this a low-to-moderate risk ingredient.  I would recommend avoiding if you have MCS or are highly sensitive to MSG, as it has chemical similarities.  I hope for more data to become available as to any possible reproductive effects.

I LOVE your posts !!

The information you share in the Chemical of the Day is so informative. Its about time someone could put all the ingredients and chemicals into layman's terms !
I have yet to find a company who actively tries to educate their customers on all the potential harmful ingredients in our household supplies, until now.

I appreciate all the Chemical of the Day posts. PLEASE keep them coming.

-one happy customer
