Fragrance-free has moved from a niche request to a mainstream positioning, driven by sensitive-skin ranges, dermatologist-adjacent brands and the clinical channel. It is also one of the most frequently misunderstood claims in personal care, because removing fragrance from the formula is only the first of several conditions. Fragrance-free is a claim about the whole product, not a statement about one line of the ingredient list.

What Fragrance-Free Requires

The claim generally means no fragrance has been intentionally added, and in many markets it also implies that no ingredient is added for the primary purpose of imparting a scent. Botanical extracts, essential oils and some preservatives can carry odour, so their role has to be justifiable on functional grounds.

The distinction between fragrance-free and unscented matters commercially. Unscented may still contain a masking fragrance added to neutralise base odour, while fragrance-free usually excludes that practice. Brands should decide which claim fits the formula and the market, because a label that mixes the two invites challenge.

Managing Base Odour Without Added Fragrance

Once the fragrance is removed, the raw materials speak. Oils, surfactants, humectants and some actives all contribute a recognisable base smell, and the sum can be unpleasant even when every individual ingredient is acceptable.

The first lever is raw material selection. Choosing lower-odour grades, such as odour-controlled oils and purified surfactants, removes most of the problem at source, which is far more reliable than correcting it later. Odour control starts on the specification sheet, not in the mixing tank.

The second lever is process. Oxidation and heat both create off-notes, so lower processing temperatures, nitrogen blanketing and shorter holding times reduce their formation. An off-note that develops in bulk cannot be fixed downstream, so prevention is the only real option.

Where a masking approach is permitted, the masking agent must itself be declared and must not reintroduce an allergen burden. This is where fragrance-free projects most often drift, so the decision should be documented.

Allergen Labelling and Documentation

Regulatory regimes differ, but most require declaration of certain fragrance allergens above defined thresholds when they are present. In a fragrance-free product the burden is usually lower, yet not automatically zero, because allergens can arrive through botanical extracts or functional ingredients. Assuming the threshold does not apply is the most common documentation gap in this category.

The practical answer is ingredient-level data. Ask each supplier whether the material contains any declarable allergen, and keep the answer on file, because the label decision depends on numbers rather than on assumptions.

Documentation should also record the internal definition the brand is working to, the market-specific rules applied, and the testing used to confirm compatibility on sensitive skin. This is the evidence package that supports the claim later.

Testing and Claims

Testing for a fragrance-free product focuses on three things: sensory acceptability without fragrance, stability of the base including odour development over shelf life, and compatibility testing appropriate to the intended positioning. Odour evaluation should be done by a small trained panel at each checkpoint, because odour drift is not captured by any instrumental measure.

Claims should be precise. Phrases such as designed for sensitive skin need a basis, and assertions about the absence of irritants should be limited to what the formulation actually omits. A narrow claim that can be proved outperforms a broad claim that cannot.

Packaging and Storage

Packaging influences odour as much as the formula. Reactive or odour-contributing materials, including some rubbers and adhesives, can introduce off-notes, and every component in contact with the product should be assessed. Barrier packs and airless formats both limit oxidation.

Sensitive-skin references appear on the barrier support cream page, the wider range is listed on the product range page, and company credentials appear on the about us page. Projects can be scoped through the inquiry page.

Fragrance-free is best treated as a formulation constraint that shapes raw material selection, process and pack, rather than as a marketing overlay. Decide the definition, source low-odour grades, control the process, document the allergens, and the claim becomes easy to defend.
