A manufacturer cannot review an existing mouthwash from a product name and an ingredient list. Reformulation starts with the current specification, the reason for the change and the parts of the product that must not move.

Start with the reason for reformulation

“We need a new formula” is not a technical brief. State what changed. Alcohol may need to be removed. A preservative system may no longer fit the market. A raw material may be unavailable. The flavour may be too sharp. The cost may no longer work at the planned volume.

Each reason creates a different development path. Removing alcohol, for example, affects solubilisation, preservation, flavour delivery and mouthfeel at the same time. It is not a one-ingredient substitution.

Provide the current product information

The useful starting pack is short:

  • Current INCI or full formula, depending on what can be disclosed
  • Finished-product specification and test methods
  • Target pH, appearance, flavour and sensory profile
  • Current packaging and fill volume
  • Destination market and intended claims
  • Known stability, compatibility or complaint history
  • Expected annual volume and target cost

If the complete formula is confidential, an NDA can be signed before technical disclosure. A benchmark sample helps, but it does not replace the specification.

Separate fixed requirements from preferences

The manufacturer needs to know which points are mandatory. An active level, alcohol-free positioning, colour, flavour identity or “compare to” requirement may be fixed. Sweetness, cooling strength, bottle shape or secondary claims may still be adjustable.

When every feature is mandatory, there is no room to solve conflicts. When nothing is fixed, the review becomes open-ended concept work. Mark each item as fixed, preferred or open for recommendation.

Define the comparison standard

For an existing product, “similar” is too vague. The review standard may include flavour onset, cooling curve, aftertaste, colour, clarity, foam, dose, cap behaviour and perceived freshness over time.

A manufacturer can compare against a retained sample or market benchmark. It should not be asked to copy an unknown formula. The objective is to rebuild an agreed performance profile within new technical, regulatory and cost limits.

Review packaging before the formula is locked

A formula that behaves in a laboratory bottle may change in the commercial pack. Pump output, liner contact, closure seal, evaporation, staining and transport temperature all matter. If the project changes the bottle, pump or single-dose format, compatibility work belongs in the reformulation plan from the beginning.

Agree what evidence is needed

Testing depends on the formula, pack, claims and destination market. The programme may include stability, microbiological limits, preservative efficacy, packaging compatibility, leakage or project-specific third-party testing. Comparative claims must be defined before the protocol is agreed.

The manufacturer should state which documents already exist, which can be created for the project and which remain the brand’s or regulatory representative’s responsibility.

Decide whether the project is ready

A review is ready when the company, target market, commercial volume, current product, change objective and decision criteria are known. If these inputs are missing, a quotation or sample will not answer the real question.
