Why Bases Feel Slippery on Your Skin

Bases feel slippery because they react with natural oils on your skin to form soap-like compounds.
Hydroxide ions in bases break down fats, creating a slick, soapy layer.
That “slip” is actually the beginning of a chemical reaction happening right on your skin.
Soap itself is a mild base, which is why it always feels smooth when lathered.
Strong bases like sodium hydroxide can feel very slippery but also dangerously corrosive.
The slipperiness is a warning sign—your skin is starting to break down at the surface.
Bases increase skin’s natural pH, giving that unnatural slick sensation.
Even mild household bases, like baking soda, can feel slightly smooth to the touch.
Slipperiness is tied to saponification, the same process used to make soap from fats.
It’s chemistry you can feel—bases literally change how your skin surface behaves.
