# Retro Castile Soaps Clean Cult Enters Castile Soap With Four Formulas And Retro Packaging By Ellen Smith | Written with AI assistance | Published 2026-10-25 | Lifestyle Source: Trend Hunter, https://www.trendhunter.com/trends/retro-castile-soaps References: [thedieline](https://thedieline.com/clean-cult-elbows-its-way-into-dr-bronners-territory-with-castile-soap-line)  Clean Cult is moving into castile soap through four concentrated formulas, giving castile soap buyers a new option within the brand's household cleaning range. The move takes Clean Cult into a soap style long linked with natural-product buyers. Its packaging steps away from the brand's usual look with brighter colors and a [1970s-inspired graphic treatment](https://www.trendhunter.com/trends/custom-formula-rx). That helps the cartons stand out on the shelf and separates this line from the rest of Clean Cult's existing range without changing the [familiar soap format](https://www.trendhunter.com/trends/forager-soap). Four concentrated formulas place Clean Cult in a segment closely tied to Dr. Bronner's while giving castile soap buyers more visual and brand choice. The retro cartons widen the category beyond its usual crunchy, text-heavy cues and make room for a more design-led take on a classic formula.
