The formulation transparency index

The short answer

The transparency index assesses grooming product categories, not named brands, against five published criteria: formulation disclosure, claim substantiation, packaging recoverability, whether a lower material option exists, and how much impact sits in the use phase. Each criterion carries a qualitative status rather than a score. It is designed to tell you where in a category a buyer has leverage and where the outcome is determined structurally.

Commercial disclosure, before the content

No affiliate link appears on this page. The affiliate layer described in our commercial terms may apply in future only to categories assessed here, and where it does, the disclosure appears above the content rather than in a footer. No affiliate arrangement is currently live. No sponsor sees an assessment before publication and no sponsor can change one.

Most buying guides rank products. We do not, because we have not tested named products under controlled conditions and publishing a ranking would mean publishing an assessment we did not make. What we can assess rigorously is how a category behaves: what it discloses, whether its claims are testable, whether its packaging is actually recovered in the UK, whether a lower material option exists that works, and how much of the impact lands with the user.

Read a row across rather than looking for a winner. A category can be Strong on claim substantiation and Poor on packaging recoverability, and those two facts point at different actions. The criteria are defined in full in how we assess, including what moves a status and what we refuse to do.

The five criteria

Formulation disclosure

Does the category routinely disclose more than the legal minimum: concentration or form of the active, pH where it matters, tested performance figures, period after opening.

Claim substantiation

Are the category's headline claims testable and tied to a published standard or a defined test, rather than resting on undefined vocabulary.

Packaging recoverability

Is the dominant format actually collected and sorted through UK household recycling, and is mono material construction common.

Lower material option

Does a refill, concentrate or waterless format exist for the category, and does it work without trading away performance.

Use phase burden

How much of the environmental impact sits with the user rather than the manufacturer, and whether behaviour change is available.

The four statuses

Words rather than numbers, because a score implies a precision this assessment does not have.

STRONG

Strong

The category as a whole performs well against this criterion, and doing better than the category norm is straightforward for a buyer to identify.

MIXED

Mixed

Practice varies widely within the category. Good and poor performers both exist and are distinguishable, but not from the front of the pack alone.

WEAK

Weak

The category norm falls short against this criterion, and a buyer has to work to find an exception.

POOR

Poor

The category systematically fails this criterion for structural reasons, and individual product choice does little to change the outcome.

The index

Read a row across rather than looking for a winner. A category can be Strong on one criterion and Poor on another, and those two facts point at different actions.

Category	C1	C2	C3	C4	C5	Note
Facial cleanser	Weak	Weak	Mixed	Strong	Mixed	pH is almost never printed despite being the specification that matters most. Solid syndet formats work well here and remove the water and the bottle together.

Category by category

Facial cleanser

The most commoditised product in the category and the most heavily marketed.

Weak Weak Mixed Strong Mixed

pH is almost never printed despite being the specification that matters most. Solid syndet formats work well here and remove the water and the bottle together.

Moisturiser

Three functional classes, a price range spanning two orders of magnitude.

Weak Mixed Mixed Weak Strong

Jars recycle better and protect formulas worse. Concentrations of anything active are rarely disclosed. Finishing the product is the largest single environmental variable available to the buyer.

Sunscreen

The best evidenced product on this list, and the one men are least likely to own.

Strong Strong Weak Poor Poor

SPF and UVA indication are tested and comparable, which is rare. Format changes are not worth making here if they reduce the amount applied, because application density determines real protection.

Shaving preparation

Lubrication sold as foam volume.

Weak Weak Poor Strong Mixed

Aerosol cans are collected in many areas when completely empty but are a poor format overall. Solid soaps and creams in tins remove the propellant and most of the packaging.

Razors and blades

The one category where the environmental hierarchy is uncontroversial.

Mixed Mixed Poor Strong Strong

Multi blade cartridges combine steel, plastic and lubricating strips and are effectively unrecoverable. Safety razor blades are single material steel but require a sharps route, never household recycling.

Shampoo

Mostly water, in a bottle, driven across the country.

Weak Weak Strong Strong Poor

Bottles are among the better performing plastic formats in UK collection. The dominant impact is hot water during use, which no packaging decision touches.

Medicated and anti dandruff

Where a treatment claim and a format claim collide.

Strong Strong Strong Weak Mixed

Actives and their concentrations are usually stated because the products sit close to a medicinal claim. Substituting a solid bar for an antifungal shampoo trades a treatment for a format.

Conditioner and styling

Function is real, disclosure is minimal.

Poor Weak Mixed Mixed Mixed

Almost nothing is disclosed beyond the ingredients list. Aerosol and pump formats dominate styling and perform badly at end of life.

Deodorant and antiperspirant

Two different products sold as one category.

Mixed Mixed Weak Strong Strong

Deodorants act on odour producing bacteria; antiperspirants reduce sweating with aluminium salts. Refill cases and cardboard tubes work well because the format is anhydrous already.

Beard oil and balm

Anhydrous by construction, over packaged by convention.

Weak Poor Poor Weak Strong

Small glass bottles with plastic droppers combine materials in quantities too small to recover. Growth claims are the weakest claim set in this index.

Body wash

The same argument as shampoo, at greater volume.

Weak Weak Strong Strong Poor

Large bottles recycle well and refill pouches are widely available. Shower duration dominates the footprint regardless of what is in the bottle.

Serums and actives

Where disclosure would matter most and appears least.

Mixed Mixed Poor Poor Strong

Airless and opaque packaging protects unstable actives and is among the least recoverable formats in the bathroom. Stated percentages describe material added, not what survives to the end of the pack.

Sponsor slot

One sponsor at a time appears here, labelled, in this position. A sponsor buys visibility and nothing else: no coverage, no assessment, no mention inside an article, no preview and no changes. An organisation whose own category is under assessment is declined. The full terms are published on the sponsorship page, including everything we refuse.
