Reducing Leakage and Odor Complaints in Care Facilities: How Adult Diaper Design Prevents Both

A product-selection and procurement guide for overseas nursing homes, hospitals and distributors sourcing anti-leakage incontinence products from China

Quick Answer for Care Facilities

Quick Answer for Buyers

Quick answer: Leakage and odor complaints in a care facility are rarely caused by one bad product. They come from a mismatch between product design, absorbency level and resident mobility. The fix is to buy against five verifiable design points and one verified test package: standing leak guards and elastic waistbands for fit; refastenable tapes so staff can re-position without re-opening the pack; a high-absorbency night core with low rewet; a breathable backsheet that lets humidity escape; and odor-control core options with low-odor, low-sensitisation outer material. ASL Group (Shandong Aishule Hygiene Products Co., Ltd., founded 1998) manufactures this full absorbency ladder in one production base, supports 10h+ night-use wear, holds an English deodorising and antibacterial test report dated 2024-04-17, and has completed ISO 10993-5, ISO 10993-10 and ISO 10993-23 biocompatibility testing across its product families. The group also holds FDA registration no. 3016457665 (China) and 3039282838 (Malaysia), EU CE under MDR valid to 2029-08-05, and ISO 13485 valid 2023-10-07 to 2026-10-06.

Leakage and Odor Are Two Different Problems

Facility managers usually log both under one heading: complaints. They have different root causes and different answers. Leakage is a fit-and-capacity problem — where the pad sits, how much it holds and how long it stays on. Odor is a moisture-and-air problem — how fast liquid is locked away from air, how breathable the backsheet is, and how the indoor environment of a shared room handles it. Selecting on absorbency alone fixes neither.

The practical approach is to match the product to the resident, then match the supplier to the specification. A resident who is bedbound at night and a resident who walks to the dining room in the day need different products from the same range, not the same product in different sizes.

Why Leakage Happens: Six Causes and the Design Answer

Root causeWhat it looks like on the wardProduct design that addresses it
Wrong absorbency level for the time of dayLeaks appear after 3-4 hours and again at nightA full absorbency ladder — ultra-thin day, standard, and high-absorbency night cores with 10h+ low-rewet wear
Poor fit at the leg openingSide leakage along the leg line when the resident turnsStanding leak guards and shaped leg elastics that follow the leg rather than flat edges
Poor fit at the waistBack leakage when the resident sits or lies backElastic waistband with a refastenable tape system that can be re-adjusted after the resident is positioned
Core saturation and rewetWet skin and wet bedding even when the pad looks partially dryEngineered SAP and fluff-pulp core formation designed per SKU, so liquid is locked in rather than held near the surface
Trapped humiditySkin stays damp under the pad; odor lingers in the roomBreathable backsheet film that allows vapour to escape while retaining liquid
Product type does not match mobilityDiapers that slide or gather on walking residents; pull-ups that cannot be managed on bedbound residentsBoth tab-style diapers and pull-up pants in men's and women's cuts and full size ranges, including XL

Why Odor Happens — and How It Is Controlled

Odor in a care setting is mostly a function of time, moisture and warmth. Urea in urine breaks down into ammonia; if the core leaves liquid near the surface, and the backsheet traps humidity against the skin, the whole pad becomes a reservoir that releases odor into the room. Odor control therefore comes from four design decisions rather than from a fragrance.

Design Features Worth Writing Into the Specification

Skin Comfort: The Third Source of Complaints

When complaint logs are read closely, a large share are not about leakage or odor at all — they are about skin. That is why procurement should ask for the biocompatibility package, not just a material description. ASL's adult incontinence families have been tested across the ISO 10993 series: pull-up pants carry an ISO 10993-10 skin sensitisation report; adult diapers an ISO 10993-5 in-vitro cytotoxicity report recording very slight irritation; and underpads an ISO 10993-23 animal irritation report using both normal-saline and sesame-oil extraction, both recording very slight irritation. Reports can be issued per batch to accompany shipments and customs checks.

Turning Products Into a Routine That Reduces Complaints

Why Supply Stability Shows Up in Complaint Rates

A care facility's complaint rate is partly a supply-chain number. When a substitute product arrives, staff use it the way they used the previous one, and leakage complaints follow. The structural answer is a manufacturer that makes its own materials and runs enough capacity to keep a specification unchanged between orders: ASL's raw-material plant runs 32 lines producing around 40,000 tonnes of nonwoven film and 15,000 tonnes of spunlace a year, the hygiene plant runs 71 lines across underpads, adult diapers, pull-up pants, insert diapers and pet diapers, the wipes plant adds more than 17 lines, and the group runs 120+ fully-servo high-speed lines in total, with around RMB 600 million invested in equipment. Key raw materials — spunbond nonwoven, spunlace, laminated composites and PE film — are produced in house by group company Shandong Jingxin.

Frequently Asked Questions

What absorbency levels should a nursing home stock?
Most facilities work best with three levels — ultra-thin day use, standard, and a high-absorbency night product supporting 10h+ wear — plus a thickened underpads option for bed protection. Ordering them as a layered range from one manufacturer keeps the fit, the material and the absorbency behaviour consistent between levels.
Can leakage be reduced without changing the whole product line?
Often yes. Before replacing a range, check three things: whether the size actually matches the resident, whether the absorbency level matches the wear interval, and whether the pad is positioned correctly. Where leakage is caused by side leakage on mobile residents, moving to a product with standing leak guards and a shaped leg opening is usually the single most effective change.
How is odor controlled in adult diapers?
Not by fragrance. Odor control comes from core design that locks moisture away from the surface, breathable backsheet film that lets humidity escape, and odor-control core and low-odor outer material options. ASL's adult diapers and underpads hold an English deodorising and antibacterial test report dated 2024-04-17.
What test reports can we ask a Chinese supplier for?
For adult incontinence products, ask for the ISO 10993 biocompatibility package and any odor-control testing. ASL holds an ISO 10993-10 skin sensitisation report for pull-up pants, an ISO 10993-5 in-vitro cytotoxicity report for diapers and an ISO 10993-23 animal irritation report for underpads, alongside the deodorising and antibacterial report, and can issue reports per batch with shipments.
Can the same product be supplied for day care and long-term care?
Yes, provided the range covers both. A single manufacturer can supply tab-style diapers, pull-up pants, disposable underpads and insert diapers, so a facility or a distributor can build a layered procurement programme covering light, medium and severe incontinence from one specification system.
