Private label lavender epsom salt from Huizhou, China, with custom scent, colour, grain size and packaging, starting at 1,000 units.
Repeated sampling rounds, scent drift between batches and lead times that slip after the PO is placed are the usual reasons a bath salt launch stalls. We make lavender epsom salt soaks under OEM, ODM and private label terms, with the scent brief, 3D packaging render and physical sample approved before mass production starts.
The base is magnesium sulfate crystal scented with lavender essential oil or a custom fragrance and tinted with skin-safe pigments. COA, MSDS and stability reports are available for compliance review, and the factory holds ISO 22716, GMPC and SMETA/Sedex.
Spas and hotels usually run larger-format soaks with coarser crystals, because staff portion them into tubs and the salt needs to dissolve visibly and evenly. Boutique and resort programmes often add a branded jar or pouch for guest retail.
Private label wellness brands and Amazon sellers tend to work with fine to medium grain in a resealable pouch or jar, sized for shelf impact and parcel shipping. Gift set retailers combine a smaller jar or sachet with other bath items, so grain, fill weight and carton dimensions are set around the set layout.
Tell us the channel and we will propose grain size, fill weight and pack format together, then confirm them on the sample.
Epsom salt is magnesium sulfate, and its crystal size sets how the soak looks and dissolves. Finer grain dissolves faster and packs more densely; coarser grain gives a more visible, spa-style presentation but a looser fill.
Scent can be a lavender essential oil blend or a custom fragrance. Dosage is the main trade-off: a higher level gives a stronger jar-open impression, while a lower level reads cleaner in the tub and suits sensitive-skin positioning. We adjust the level on the sample until the scent matches your brief.
Colour comes from skin-safe pigments, from natural-looking off-white to soft purple. We describe the experience as a calming, relaxing soak and make no treatment claims. With 3000+ formulas in the library, most briefs start from an existing base and are tuned rather than built from zero.
Options are fixed at the design step and confirmed on the physical sample.
Lavender essential oil blends or a custom fragrance. Intensity is tuned on the sample, so you approve the level before bulk.
Single or multi-colour with skin-safe pigments. Fine, medium or coarse grain is selectable, with a trade-off between dissolve speed and look.

Scent, colour and fill weight are the three things that drift between batches. Production runs in a dust-free workshop with automatic filling, labeling and packing machines, so fill weight and label placement do not depend on hand work. The factory has 30 years of personal care manufacturing behind its process control.
In-process quality checks run during mass production, and every order goes through 100% final inspection before packaging. Approved samples are kept as the reference for scent and colour, so each batch is compared against what you signed off.
Copies of all certificates are available on request.
