Every Wednesday we'll bring you "What's In It Wednesday". A blog about what's in typical bath and beauty products, including the good, the bad and the ugly. We want you to know what we use or don't use in our products and why!

Today's ingredient comes from that same bottle of generic, clear liquid hand soap I found under my sink. 

The next ingredient listed is:  cocamidopropyl betaine  It is in all kinds of household products such as shampoos (even baby shampoos), hair conditioner and styling moose/gels, hand soap (liquid and bar), dish soap, facial cleanser, make up, etc.  

Cocamidopropyl betaine is a medium strength surfactant, which means it basically allows the water to penetrate the oils on the skin and remove dirt.  It is generally considered safe for most skin.  However, it is believed to be an allergen. 

Why is it in so many products?  Because it's not considered to be an eye irritant, it's used it lots of baby products and anything that else that might get near the eyes (like make up and hair product).  It also mixes well with other chemicals and has some antiseptic properties.  However, If you have sensitive skin or allergies, you might want to avoid this chemical.
