99% Water Wipes: Claim Rules & Private Label Guide

Short answer

“99% water” describes the liquid in the wipe: purified water makes up at least 99% of the formula, and everything else (cleansing agent, preservative, pH adjuster, any skin conditioner) fits into the remaining 1% or less. It is a percentage claim, so the brand must hold the full formula with exact concentrations to prove it. Because so little room is left for preservatives, high-water wipes need careful preservative design and a preservation efficacy (challenge) test before launch.

What does “99% water” on wet wipes mean?

A “99% water” wipe is a wipe whose liquid formula is at least 99% purified water by weight. The claim describes the lotion, not the nonwoven sheet. The remaining 1% or less typically holds a mild cleansing or soothing ingredient, a preservative system and a pH adjuster such as citric acid. Some brands go further and claim 99.9%, which leaves even less room for anything other than water.

The claim appeals to parents because it signals a short ingredient list and minimal exposure to fragrance and additives. For a brand owner, it is a quantitative claim: it is either true for the formula or it is not, and regulators can ask you to prove it.

Term	What it usually means	What you need to prove it
“99% water”	Water is ≥99% of the liquid formula by weight	Full quantitative formula (every ingredient with its concentration)
“99.9% water”	Water is ≥99.9% of the liquid formula	Same, with the remaining 0.1% fully accounted for
“Water-based”	Water is the main ingredient	Ingredient list in descending order
“Fragrance free”	No added fragrance ingredients	Formula and raw-material declarations (no masking fragrance)

How do you substantiate a percentage claim?

In every main market the claim must be backed by evidence held before the product is sold:

EU: Regulation (EU) No 655/2013 sets common criteria for cosmetic claims. Claims must be truthful and “supported by adequate and verifiable evidence”, and the responsible person must keep that evidence consistent with the product information file (EUR-Lex). Article 20 of Regulation (EC) No 1223/2009 prohibits wording that implies characteristics the product does not have.
US: The FTC expects advertisers to have a reasonable basis for objective claims before they make them (FTC). A percentage is an objective claim.
Great Britain: the Responsible Person must be able to prove that any marketing claim is correct (GOV.UK).

In practice, your evidence file should contain the quantitative formula signed off by the producing factory, the water specification (for example purified water quality), and batch records showing the formula is made as written. Keep the claim consistent everywhere: pack, Amazon listing, images and ads.

Why are high-water wipes harder to preserve?

Water supports microbial growth, and a wet wipe is opened and resealed many times. A conventional wipe formula can use a broader preservative system; a 99% water formula has very little room for it. The design challenge is to keep the product protected for its whole shelf life with a minimal, skin-friendly system.

Preservation efficacy (challenge) test. ISO 11930 is the reference method for evaluating the antimicrobial protection of a cosmetic product (ISO). Test the finished wipe formula, ideally on the chosen substrate, because fibres can bind some preservatives.
Raw-material and water hygiene. With few preservatives, the purity of the water and the cleanliness of the liquid preparation and converting line matter more. Ask how the factory treats and tests its process water.
Packaging. A good lid or strong reseal reduces contamination and drying in use. See the packaging guide.
Shelf life and PAO. Stability data decide how long the product lasts before and after opening. See do wet wipes expire?

What should a private label 99% water wipe specification include?

If you are benchmarking against a well-known water wipe brand, write the spec in numbers so samples can be compared fairly:

Spec item	Typical options to decide
Liquid	Water share (99% or 99.9%), the remaining ingredients and their roles, pH target, fragrance free
Substrate	Fibre (viscose, lyocell, cotton or blends; plastic-free if selling in the UK), GSM, texture
Sheet	Size and count per pack, matched to the benchmark
Liquid loading	How wet each sheet is; too dry feels cheap, too wet drips
Pack	Flip-top lid or resealable sticker, multipack format
Testing	Challenge test (ISO 11930), microbiology per batch, stability, plus market-specific safety assessment

The fibre options and GSM vocabulary are explained in what wet wipes are made of. If you are launching a new brand, the full sequence is in how to start a baby wipes brand.

How should you word the claim on the pack?

Say what the percentage refers to if there is any room for doubt, for example “made with 99% water” next to the ingredient list.
Do not imply “only water”. The ingredient list must show every ingredient, preservatives included. A claim that suggests the wipe contains nothing else would be misleading.
Avoid “preservative-free” unless the formula truly contains no preservative and the claim is supported; EU common criteria also discourage claims that denigrate ingredients that are legally used.
Be careful with “suitable for newborns” or “hypoallergenic”. These are claims too and need their own evidence, such as a safety assessment and, where you choose, dermatological testing.
Do not copy a competitor’s trade dress. Benchmark the product, not the design or name.

How does LX Wipe handle 99% water projects?

We specify the formula with the partner factory, request the quantitative formula and challenge-test results that cover your exact product, and compare samples against your benchmark on wetness, softness and pack performance. Test reports belong to the laboratory client named on the report, usually the producing factory, and we provide copies on request. Samples usually take 7–10 days once the specification is agreed.

Benchmark a 99% water wipe against your target

Send the product you want to match. We prepare high-water samples on the substrate you choose and share the formula and test documents the partner factory can provide.

Frequently asked questions

What does 99% water mean on baby wipes?

It means purified water makes up at least 99% of the wipe’s liquid formula by weight. The remaining 1% or less holds ingredients such as a preservative, a pH adjuster and a mild cleansing or soothing agent.

Are 99% water wipes preservative-free?

Usually not. A wet product that is opened repeatedly needs protection against microbial growth, so most high-water formulas still contain a small preservative system, which must appear in the ingredient list.

How do I prove a 99% water claim?

Hold the full quantitative formula from the producing factory, batch records showing it is made as written, and keep the claim consistent across pack and listings. EU rules require adequate and verifiable evidence; the FTC expects a reasonable basis before the claim is made.

Which test shows a high-water wipe is well preserved?

A preservation efficacy (challenge) test, with ISO 11930 as the reference method for cosmetics, run on the finished formula, ideally on the chosen substrate.

Can LX Wipe make private label 99% water wipes?

Yes. LX Wipe specifies high-water baby wipes with vetted partner factories, including plastic-free substrate options, and provides the formula and test documents the factory holds.
