Private Label Bath Bomb
The fizz that sold the world on bathing as entertainment.
Bath bombs are entertainment first, skincare second — and the video is the product: the fizz, the color reveal, the botanicals floating free. It is also a manufacturing discipline: hardness (survives shipping), fizz (performs in hard water), and color payoff all at once.
We press bombs with calibrated hardness and fizz profiles, offer color-reveal and layered-effect builds, botanical inclusions and hidden-color cores, and pack into the gift boxes that make them a quarterly gift-channel winner.
The components that do the work here
INCI names and typical levels reflect publicly documented formulation practice. All values are adjustable in your build.
| Ingredient (INCI) | Typical Level | Function & Benefit |
|---|---|---|
| Sodium Bicarbonate | 40–60% | Fizz base |
| Citric Acid | 20–35% | Fizz reaction |
| Corn Starch / Kaolin | 5–15% | Hardness binder |
What brands ask us about this category
Why this MOQ?
Pressing, curing and boxing are batch processes; 1,000 is our standard floor and larger runs improve per-unit cost and keeps per-unit cost gift-channel viable.
Do they survive summer shipping?
With calibrated hardness and humidity-barrier wrapping, yes — we ship-test to your destination climate before mass production.
Can we do custom shapes?
Standard sphere, plus heart/star/seasonal molds from tooling library; full custom shapes need mold fabrication quoted separately.
Blending is where a dry formula is won or lost
Two powders mixed together behave differently from either one alone. Density, particle shape and moisture all affect whether the blend stays uniform from the first scoop to the last.
That is why the blend is designed against segregation rather than checked for it afterwards, and why fill verification is done per unit rather than once per batch.
Where each route fits a brief
Two dry formats can look identical in the pack and behave completely differently in water.
| Format | Process demand | Where it fits |
|---|---|---|
| Foaming powder | Surfactant-loaded and moisture-critical | Cleansing powders decanted by the customer |
| Bath bomb | Compression and humidity control | Gift-channel formats built on a visible action |
| Low-dust agglomerate | Fewer fines, cleaner handling | Retail formats where dust draws complaints |
| Dry shampoo powder | Fine, low-residue, static control | Waterless hair-refresh formats |
Where this blend can be adjusted
- Hardness/fizz calibrated pressing
- Color-reveal core technology
- Botanical inclusions
- Six-pack gift boxing
The stages this format passes through
- 1
Hold for release on moisture
The batch is released on a moisture reading rather than on an assumption carried over from the raw materials.
- 2
Mill to a defined distribution
Milling runs to a particle size target rather than to a time, and the result is verified between batches.
- 3
Test through the shipping route
The product is cycled through transport conditions before release, because humidity damage rarely shows at the bench.
- 4
Blend in density order
Components are added in an order that discourages segregation, so the blend stays uniform across the whole run.
What decides how this flows and keeps
Dissolution in use
A soak or a bath product is judged by how it dissolves. Granule size and any coating are the two levers.
Caking and anti-caking
Anti-caking agents are dosed against the humidity of the destination market, not written in as a fixed line.
Colour and botanical inclusions
Inclusions are chosen for how they look in the pack and what they do in use, and both are checked after the shipping cycle.
Static in fine grades
Very fine powders carry static, which makes them cling to equipment and to the inside of the pack. Handling is designed around it.
What this blend can be filled into
Mixed-variant orders can split the stated MOQ across formats under one brand.
| Format / Specification | MOQ | Lead Time |
|---|---|---|
| Classic bath bomb 180 g | 1,000 pcs | 10–15 days |
| Color-reveal core variant | 1,000 pcs | 10–15 days |
| Gift box of 6 | 1,000 boxes | 10–15 days |
MOQ and lead time above are the standard liquid, cream and gel route. The real minimum is set by the manufacturing system rather than the category: surfactant systems (shampoo, body wash) start at 2,000 pcs, stick formats at 3,000, and powders and sheet masks at 5,000 — with longer production runs to match.

Buyer guides for this build
Before you brief a supplier on this category, these are the guides that answer the questions buyers ask next — timelines, order quantities, cost structure and compliance.
The paperwork that travels with a dry order
The line is GMPC and ISO 22716 certified and runs in-house under manufacturing licence 粤妆20250206, with batch traceability from raw material to carton.
Every production order ships with a certificate of analysis, a stability summary, a microbiology report and MoCRA / CPNP-ready documentation.
Moisture is what decides whether a powder still flows at the end of its shelf life, so the retained Golden Sample is held as the reference for appearance, flow and particle behaviour at release.
