Baby Castile Soap Bar – Ultra-Gentle Organic Soap for Newborn Skin

$14.99 USD

Inspired by the traditional Castile soaps of 1600s Spain, this Baby Castile Soap Bar is handcrafted to be as gentle, simple, and pure as possible for delicate newborn skin.

Each tiny bar is made almost entirely with organic olive oil, plus a touch of organic coconut oil for a soft, silky lather. This gentle blend stays true to the Castile tradition while offering a smoother wash that feels especially mild on sensitive skin.

Our baby bars are cured for 4–6 weeks and made using a superfat method, meaning we use the minimal amount of lye necessary for a softer, more conditioning, and baby-friendly soap.

Frequently Asked Questions

Is this soap safe for newborn skin?

This soap is crafted to be as gentle and simple as possible, with just three ingredients and no added fragrance or detergents. Many parents choose it for delicate newborn skin.

Why isn’t it made with 100% olive oil?

A traditional 100% olive oil Castile bar can feel very slippery. The small addition of coconut oil helps create a smoother, softer lather while keeping the bar very mild.

What does “superfat” mean?

Superfatting means using extra oils and the minimal amount of lye necessary, resulting in a more conditioning and gentle finished soap.

How long does one bar last?

Because each bar is small and designed for baby use, longevity depends on frequency of use. Storing it on a draining dish will help it last longer.

Does this soap contain fragrance or essential oils?

No. This bar contains no added fragrance, essential oils, dyes, detergents, or fillers.
