Is this for you at all

Liquid soap is one of the easier things on this site to make and two decisions can turn it into a much harder product: the dispenser, and the claim.

The making is genuinely accessible

A liquid hand or dish soap is a formulation exercise with no filed process, no mandatory kill step and no panel of testers. Compared with a dairy product or a sunscreen the barriers are low, which is why this is a common first product for somebody moving from bar soap into liquids.

The foaming pump is the first trap

It looks like a closure choice and it is a formulation decision. A foamer needs a thin liquid to work, so a product developed at normal hand soap viscosity will not foam, will clog, or will deliver nothing at all. The dispenser has to be chosen before the formula is settled, which is the reverse of every other property here.

The claim is the second

Saying a product kills germs puts it under FDA as a drug if it is for skin, or under EPA as a pesticide if it is for surfaces. A plain soap that says it cleans is neither. The sentence is the whole difference and it is written by somebody thinking about marketing rather than agencies.

Hand sanitizer is a drug, not a soap

Alcohol rubs and antiseptic washes are over-the-counter drug products, which is a different regime from the cosmetic one a plain liquid soap sits in. A maker adding sanitizer to a soap range has changed category, not just added a product.

Who it suits

Somebody who will decide the dispenser early, keep the claims plain, and test the actual filled package rather than the formula in a beaker. None of that is difficult and all of it is skipped routinely.

What this property covers

The foamer and the dilution it forces, which agency a claim puts you in front of, the failures that come from mismatching product and dispenser, and the container decisions. It does not formulate.
