Label teardown

What the pack promises versus what the label chemistry actually is.

The marketing claim

“Kills 99.9% of bacteria without water”

The chemical reality

WHO-style sanitiser is 70–80% alcohol plus a drop of glycerin. The branded gel is that mix with a pump. 99% isopropyl alcohol diluted 7:3 with water is the same working strength in litres, not 500 ml pumps. Flammable — not a drink, not a medicine.

The Marketing Claim & The Catch

A 500 millilitres pack of Carex Complete Hand Sanitiser typically retails around £3.00 in household cleaning. That is a UK shelf-price snapshot for the maths on this page — not a live shop quote or a manufacturer RRP. Listings, sizes and deals move. The marketing line is that you are buying a finished lifestyle product, not a weighed chemical.

On the pack: Kills 99.9% of bacteria without water; and Dermatologically tested gel.

The catch: WHO-style sanitiser is 70–80% alcohol plus a drop of glycerin. The branded gel is that mix with a pump. 99% isopropyl alcohol diluted 7:3 with water is the same working strength in litres, not 500 ml pumps. Flammable — not a drink, not a medicine.

Proprietary Blend & Dosage Breakdown

The labelled active is Ethanol / isopropanol (alcohol) at 70%. Everything else in the pack is water, glycerin and a fragrance.

Even when the pack is sold as “pure” or ready-to-use, the dose that actually does the work is Ethanol / isopropanol (alcohol). The rest is how they get it into a bottle you will pick up.

Branded working strength is whatever comes out of the bottle. The bulk alternative is 99% Isopropyl alcohol 99% (IPA) diluted to ~70%, mixed to 7:3 (7 parts 99% IPA + 3 parts water → ~70%).

Working strength: 7:3 (7 parts 99% IPA + 3 parts water → ~70%). Indicative cost £2.24 per diluted litre — 63% below a typical branded pack on a per-litre basis, before you reuse leftover bulk.

Follow the mixing method and the supplier SDS. Wear the listed PPE. Do not mix incompatible oxidisers, acids or ammonia.

  1. Highly flammable. No flames, no charging phones beside an open bottle. Gloves if you have broken skin. Do not drink.
  2. 7 parts 99% IPA + 3 parts water makes about 70% v/v. Optional: 1–2% vegetable glycerin so hands crack less.
  3. 5 litres of 99% makes about 7.1 litres of 70% sanitiser. A 500 ml Carex pump is one-fourteenth of that.

Active ingredient and cheaper alternative — FAQ

What is the active ingredient in Carex?

Carex Complete Hand Sanitiser is labelled as Ethanol / isopropanol (alcohol) at 70%. The carrier is Water, glycerin and a fragrance. Pack size: 500 millilitres. The bulk equivalent we index is Isopropyl alcohol 99% (IPA) diluted to ~70% (CAS 67-63-0).

Is Isopropyl alcohol 99% (IPA) diluted to ~70% safe on the intended surface?

Used at the listed working strength (7:3 (7 parts 99% IPA + 3 parts water → ~70%)), the dupe is the same chemistry as the branded pack for kettles, ceramics and washable hard surfaces. That is not a blanket all-clear: read the supplier SDS, wear the listed PPE, keep acids away from hypochlorite, and follow UK HSE/COSHH rules. Wellness teardowns are supplements, not medicines.

Is there a cheaper alternative to Carex Complete Hand Sanitiser?

Yes. The bulk equivalent is Isopropyl alcohol 99% (IPA) diluted to ~70% (CAS 67-63-0). Indicative saving 63% per working litre versus a pack that typically retails around £3.00. Working strength: 7:3 (7 parts 99% IPA + 3 parts water → ~70%). Live shop prices move.

How do you mix the Complete Hand Sanitiser dupe stack?

Highly flammable. No flames, no charging phones beside an open bottle. Gloves if you have broken skin. Do not drink. 7 parts 99% IPA + 3 parts water makes about 70% v/v. Optional: 1–2% vegetable glycerin so hands crack less. 5 litres of 99% makes about 7.1 litres of 70% sanitiser. A 500 ml Carex pump is one-fourteenth of that. This is a household disinfectant comparison, not medical advice and not a licensed antiseptic.
