Dr. Bronner's Pure-Castile Liquid Soap Refill — Baby Unscented 32oz, Concentrated Multi-Use & Low-Plastic

Dr. Bronner's Pure-Castile Liquid Soap Refill (32oz, Baby Unscented) is a concentrated, multi-use plant-based soap made with regenerative organic certified oils and designed as a low-plastic refill for face, body, hands, laundry, dishes and home cleaning.

This refill carton delivers the same clean-rinsing Pure-Castile formula Dr. Bronner's is known for—now in a 32oz pack formulated without fragrances, dyes, or synthetic thickeners. The baby unscented version is intentionally mild for sensitive skin and versatile enough to replace several single-purpose cleaners around the home. Formulated with a high percentage of organic and fair trade ingredients and newly sourced regenerative organic certified coconut, palm kernel and olive oils, the refill carton reduces plastic by approximately 86% per quart versus comparable bottles.

How concentrated is this soap and how should I dilute it?

The liquid is highly concentrated—about three times stronger than many standard liquid soaps—so dilution is recommended for most tasks. Use small amounts diluted in water for everyday handwashing or full-strength sparingly for stubborn cleaning jobs.

• Hand soap: dilute 1 part soap to 3–5 parts water for a gentle foaming dispenser.
• Body wash: dilute 1 part soap to 2–4 parts water depending on lather preference.
• General cleaning: mix 1:40 for mopping or multi-surface cleaning.
• Laundry or dishes: test small amounts—start with 1–2 teaspoons per load or sink.

What ingredients are in this unscented refill and why do they matter?

The formula centers on plant-derived oils—now including regenerative organic certified coconut, palm kernel and olive oils—plus fair trade and organic inputs that support sustainable sourcing. There are no synthetic preservatives, dyes, or thickeners; the characteristically rich, natural lather comes from true soap chemistry rather than additives.

• Regenerative organic certified oils: coconut, palm kernel, olive.
• Over 70% certified organic and fair trade ingredients.
• No synthetic foaming agents, plasticizers, or artificial colors.
• Vegan and non-GMO formulation with biodegradable ingredients.

Which uses and household tasks can this single product replace?

Dr. Bronner's Pure-Castile is marketed as an 18-in-1 product and covers personal care plus many household cleaning jobs—ideal for simplifying your cleaning closet or bathroom. Its versatility saves space and reduces the need for multiple specialized cleaners when diluted appropriately.

• Personal care: face, body wash, hand soap, baby wash (unscented).
• Home cleaning: all-purpose surface cleaner, mopping, glass cleaning when diluted correctly.
• Household chores: laundry booster, dishwashing, pet washing.
• Outdoor uses: gardening gear wash, gentle vehicle rinses when diluted.

How is the refill carton better for the environment and what should I expect packaging-wise?
