Handcrafted small-batch soaps and plant-based skincare inspired by sculpture, textiles, and mindful living.
Mater Soap, founded by Addison Walz in Brooklyn, NY, handcrafts small-batch cold-process soaps and organic body products. Inspired by sculpture, architecture, and textiles, Mater celebrates utilitarian objects that quietly serve daily life. Using 100% natural, sustainably sourced plant ingredients such as smoky pine tar, kaolin clay, and sea plants, each product nourishes the body and mind while minimising ecological impact. Vegan and cruelty-free, Mater embraces the minimalist beauty of traditional bar soaps and the subtle alchemy of plant-based skincare.
Mater honours both symbolic and actual mothers, drawing inspiration from the Woman of Willendorf, one of the earliest representations of the human form. Each creation reflects a thoughtful balance of design, craft, and functionality, connecting artistry with everyday rituals.
process Mater

Mater produces small-batch, handcrafted soaps and body products using 100% natural, sustainably sourced plant ingredients. Each batch is carefully mixed to preserve the integrity and subtlety of the oils and clays.

The cold-process method allows the soaps to cure slowly, developing texture, hardness, and long-lasting performance while maintaining the nourishing qualities of the botanicals.

Each bar is finished by hand, scraped, smoothed, and shaped to celebrate the tactile, artisanal quality of Mater Soap, combining craft, design, and function in every piece.
