Product reformulation
Reformulation begins with a known formula and a clear reason for changing it. The brief should distinguish attributes that must be preserved from those intended to improve, using the current product as a reference where possible.
Set the change objective
Projects may address an unavailable or restricted ingredient, a stability problem, application feel, manufacturing constraints, cost or entry into another market. A retailer or brand ingredient policy can also drive changes, but terms such as clean beauty need a defined specification rather than being treated as a universal safety standard.
Develop and compare prototypes
Formulators assess ingredient functions and interactions, prepare trial versions and compare relevant properties with the reference. Replacing one raw material can affect preservation, viscosity, colour, fragrance, packaging interaction or process behaviour even when its intended function is similar.
Validate the revised product
The change assessment determines the necessary stability, microbiological, compatibility, safety and performance work. Existing claims and documentation should be reviewed for continued relevance. The deliverable should record the revised composition, process, specifications and evidence, not merely a substituted ingredient list.
