The Marketing Claim & The Catch
A typical 500 millilitres pack of Carex Complete Hand Sanitiser is about £3.00 in household cleaning. That is a snapshot, not a live Amazon price — 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%).

The Active Chemical Alternative (Dupe Stack)
The dupe stack is Isopropyl alcohol 99% (IPA) diluted to ~70% at 99% bulk. Indexed as CAS 67-63-0, formula C3H8O. Buy it as 5 litres for about £15.99 from Amazon UK.
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.
- 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.

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 typical £3.00 pack. Working strength: 7:3 (7 parts 99% IPA + 3 parts water → ~70%). Live shop prices move.

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.
