Hand creams are everyday essentials a reassuringly familiar product to make and sell. But because most are emulsions containing water, they sit firmly in the camp of products that need proper preservation and challenge testing, and a hand cream is a cosmetic requiring a CPSR. This guide explains what the assessment covers for hand creams and lotions.
For the fundamentals, see our guide to what a CPSR is. Here we focus on hand creams.
Hand creams are emulsions
Most hand creams are emulsions blends of water and oil held together by an emulsifier, giving that familiar smooth, absorbent texture. The presence of water is the single most important fact about them from a safety point of view, because water means microbes can grow, which means the product needs a robust preservative system and testing to prove it. This sets hand creams apart from anhydrous balms and oils.
Understanding that your hand cream is a water-containing emulsion is the starting point for its assessment. It tells you immediately that preservation and challenge testing will be central, and that the formula's stability keeping the emulsion from separating will matter. A hand cream is a more involved product to assess than a simple oil, precisely because of its water.
Preservation is essential
Because a hand cream contains water, it needs a preservative system there is no safe “preservative-free” water-based cream. Without effective preservation, an emulsion can grow bacteria, yeast and mould, becoming unsafe and potentially harmful, especially as it is dipped into repeatedly and used on hands that touch everything. Preservation is not optional here; it is fundamental to the product being safe.
Choosing an appropriate, compliant preservative (from the permitted list, at the right level for the right pH) is a key formulation decision. Our preservatives guide explains the options and rules. The assessment confirms your preservative is suitable, permitted and used correctly for your specific formula.
The challenge test
To prove the preservative system actually works, a water-based hand cream needs a challenge test (preservative efficacy test) a laboratory test that deliberately introduces microbes and confirms the product can control them over time. This is one of the more important pieces of testing for an emulsion, because it demonstrates that the preservation is genuinely effective, not just present on paper.
The challenge test result feeds directly into the safety assessment, giving the assessor confidence that the product will stay safe through its shelf life and repeated use. Our challenge test guide explains what it involves. For a hand cream, skipping this is not an option it is core evidence of safety.
pH and skin compatibility
Skin is naturally mildly acidic, and a hand cream should be formulated to a skin-compatible pH so it is comfortable and supports the skin barrier. The pH also affects how well the preservative works — many preservatives are only effective within a certain pH range so pH ties the preservation and skin-comfort considerations together. An emulsion at the wrong pH can be both less well preserved and less kind to skin.
The assessment looks at pH as part of judging both safety and preservative efficacy. For makers, measuring and controlling the pH of each batch, and reporting it for the assessment, is an important habit. A well-formulated hand cream sits at a sensible, skin-friendly pH.
Frequent use and washing
Hand cream is used frequently often many times a day on skin that is also washed repeatedly, exposed to detergents, and sometimes already dry or cracked. This pattern of heavy, repeated use on potentially compromised skin is part of the foreseeable-use picture the assessment considers. A product used this intensively needs to be reliably gentle and well tolerated.
It also means hand creams are often marketed for very dry, hardworking or sensitive hands, which can raise expectations around mildness and barrier support. The assessment accounts for how heavily and how often the product is realistically used, which reinforces the need for a gentle, well-preserved, stable formula.
Fragrance, actives and allergens
Hand creams are usually fragranced and may contain actives humectants, barrier ingredients, sometimes urea or other functional materials. Fragrance brings the usual allergen declaration requirements, and because hand cream is leave-on, the stricter leave-on allergen threshold applies. Any actives need checking against their limits, and some functional ingredients have restrictions.
The assessment checks fragrance levels, calculates allergens for the label, and reviews any actives against the restricted-substance rules see our restricted ingredients and allergen labelling guides. Knowing your complete formula, including every active and the fragrance's allergen profile, is essential.
Claims and barrier benefits
Hand creams often carry claims about moisturising, protecting, repairing or soothing dry hands. Moisturising and softening claims are standard cosmetic territory. Claims that stray into treating conditions healing eczema, curing dermatitis are medicinal and would take the product outside cosmetic classification. “Helps protect dry, chapped hands” is cosmetic; “treats eczema” is not.
Where you claim a specific benefit such as long-lasting hydration or barrier support, you should be able to support it. Keeping claims cosmetic and supportable is particularly relevant for hand creams aimed at very dry or problem skin, where the temptation to imply medical benefits is strong.
Packaging: tubes versus jars
How a hand cream is dispensed affects its contamination risk and therefore its preservation challenge. A jar, dipped into repeatedly with fingers, exposes the product to microbes far more than a tube or pump, which dispenses without the user touching the bulk product. This does not change the fundamental need to preserve a water-based cream, but it does influence how demanding the real-world contamination scenario is, and the assessor takes the packaging into account.
Packaging also matters for stability and compatibility: the cream should be tested in the actual container it will be sold in, since the pack can interact with the formula, and an emulsion can behave differently in different containers. Choosing appropriate packaging and ideally a format that limits finger contact supports both a more robust preservation story and a sounder safety assessment.
Common hand cream mistakes
The most serious mistake is inadequate preservation under-dosing the preservative, using one that does not suit the product's pH, or being tempted by “preservative-free” marketing for a water-based cream, which is simply unsafe. A second is skipping the challenge test, so there is no actual evidence the preservation works. A third is ignoring pH, leaving the cream at a level that is uncomfortable on skin or that undermines the preservative.
Other common slips include medicinal claims for very dry or problem skin (“treats eczema”) and forgetting allergen declaration at the stricter leave-on threshold. Each is avoidable: preserve properly and prove it, control pH, keep claims cosmetic, and declare allergens. A hand cream is a familiar, achievable product to make compliantly — the pitfalls almost all trace back to underestimating the demands of a water-containing emulsion.

Does hand cream need a CPSR?
Yes. A hand cream is a cosmetic needing a CPSR, PIF, Responsible Person, notification and compliant labelling. As a water-containing emulsion, its preservation and testing make the assessment especially important.
Does hand cream need a preservative?
Yes. Because it contains water, a hand cream needs an effective, compliant preservative system. There's no safe preservative-free water-based cream without preservation it can grow harmful microbes.
What is a challenge test and do I need one?
It's a lab test that introduces microbes to confirm your preservative system controls them over time. A water-based hand cream needs one as core evidence that it stays safe through its shelf life and repeated use.
Why does pH matter for hand cream?
A skin-compatible pH keeps the cream comfortable and supports the skin barrier, and it affects preservative efficacy, since many preservatives only work within a certain pH range. The assessment checks it.
Are hand cream allergens treated strictly?
Hand cream is leave-on, so the stricter leave-on allergen threshold applies. Fragrance allergens above that threshold must be declared in the ingredient list.
Can I say my hand cream treats eczema?
No. Treating or curing skin conditions is a medicinal claim that would take the product outside cosmetic classification. Use cosmetic claims like moisturising and helping protect dry, chapped hands.
Is hand cream's frequent use a safety factor?
Yes. It's used many times a day on skin that's washed and often dry or cracked, so the assessment treats it as heavy, repeated use on potentially compromised skin, reinforcing the need for a gentle, well-preserved formula.
Does the packaging affect hand cream safety?
It influences contamination risk: a jar dipped into with fingers exposes the product to microbes more than a tube or pump. It doesn't remove the need to preserve a water-based cream, but the assessor takes the packaging into account.
Can I market my hand cream as preservative-free?
Not safely, if it contains water. A water-based emulsion needs an effective preservative system, and 'preservative-free' marketing for such a product is both misleading and unsafe.
