Feminine care capsules OEM is the category where a single word on the pack can decide whether a product ships as a cosmetic or waits eighteen months for a medical device review. The format itself – a sealed single-dose bead of oil or a gentle wash-off – is unremarkable. The positioning is not. This article sets out what the format can honestly do and where brands usually overreach.
1. Cosmetic versus medical positioning
In the EU, a product that cleanses, perfumes or moisturises the external intimate area is a cosmetic. A product that treats, prevents or relieves a condition – itching, infection, irritation caused by an infection – is a medicinal product or a medical device, with a completely different filing path. The same formula can sit in either bucket depending on the label copy. Words such as soothing, gentle, pH-balanced and fresh sit on the cosmetic side; words such as anti-itch, antiseptic, treatment and relief move the product out of it.
2. Formula constraints
Mucosal-adjacent skin is thinner, less keratinised, and less tolerant of fragrance and surfactants than the rest of the body. A workable single-dose formula is short: a light carrier oil, an emollient ester, a low level of a mild non-ionic emulsifier, and a pH-adjusted aqueous phase if the product is a wash. Fragrance is usually omitted, and where present it should be a low-allergen concentrate at under 0.1 percent. Preservative choice follows the same logic – the fewest components that pass the challenge test.
3. pH and the number that gets audited
External intimate skin sits at a pH between 4.5 and 5.5 in most published measurements. A wash formulated at pH 4.2 to 4.8 is described as pH-balanced, and that number is testable, so it should be printed with a tolerance. A product claiming to maintain vaginal pH is making a different and much larger claim that needs clinical data, not a litmus strip.
4. Testing that a retailer will ask for
- HRIPT or a human patch test on 50 or more subjects, on the final formula.
- Preservative challenge test per ISO 11930 for any aqueous fill.
- Microbial limits per ISO 17516, on the filled unit, not the bulk.
- Ocular and mucosal irritation screen if the product may contact the area.
- Stability in the final pack, including a 40 degrees Celsius hold.
5. Packaging that protects the claim
A single-dose bead is a hygiene claim in itself: no fingers in a jar, no air exchange. That is the strongest argument for this format over a tube and it should be printed as an instruction – one bead per use, discard after use – rather than implied. An opaque jar or a blister card keeps the beads out of light, and a desiccant sachet prevents the shell from softening in humid markets.
6. Markets and paperwork
In the EU the product needs a Responsible Person, a Product Information File and a CPNP notification. In the US, cosmetic products now need facility registration and product listing under MoCRA, plus safety substantiation held on file. Several Asian markets require additional notification for intimate-area products and may reclassify them. A supplier should be able to name the product category it will file under before you print artwork.
7. What we will and will not quote
We produce the cosmetic format: a gentle oil or wash bead, fragrance-free options, pH-adjusted, with a full safety file. We do not produce a product positioned to treat or prevent an infection, and any brief that asks for that wording will be routed to a regulatory discussion before sampling. The feminine care capsule listings show the fills we hold in stock, and the capsule line guide explains the filling constraints that apply to a 1.0 ml bead.
