Ingredient Glossary A–Z

The B.Bath Standard (our promise)

Every ingredient must serve a clear purpose for skin health: nothing is included without dermatological or functional justification. We reformulate until it meets our standards for safety, comfort and real-world family use.

Our testing circle includes paediatric dermatologists, sensory-integration specialists, educators and over 200 families, who evaluate each formula for barrier protection, sensory tolerance and comfort during daily care.

All ingredients are screened quarterly against the EWG Skin Deep® database, with PCR reports and COAs reviewed for usage limits and purity. We comply with EU bans, IFRA fragrance-allergen thresholds, and our own Sensory-Safe™ Standards, an internal framework grounded in dermatology, neuroscience and family-based research.

Our evidence-based approach

Instead of overwhelming formulas, we prioritise what actually works. Before an ingredient earns its place, we ask:

• Does it provide a measurable benefit to a child’s barrier health?
• Will it support sensory regulation, or risk sensory overload?
• Can a child’s developing system process it comfortably?
• If a reaction occurs, can parents easily identify the cause?

We leave out strong-smelling “superfruits”, concentrated essential-oil blends, exotic botanicals with intense scents, and any additive included purely for marketing appeal.

Real-world testing that matters

Beyond laboratory irritation screens, we study how children respond in natural family routines:

• Do children pull away when the product touches their skin?
• Do they react to the smell (scrunching their nose, turning away)?
• Do they wipe it off immediately, or stay calm and comfortable?

These small observations help us refine each formula for calm, cooperative and enjoyable self-care.

Who we work with: paediatric dermatologists · sensory integration therapists · special educators · 200+ families with diverse skin types and sensory profiles.

Our commitment to transparency

This glossary explains every ingredient we use, every claim we make, and the evidence behind both. Families deserve to understand not just what goes into skincare, but why, and how it supports preventive care and barrier health.
