Specifications a manufacturer can execute
A formula is not a specification. Tolerances, process steps and controls are what make production repeatable.

Handing a manufacturer an ingredient list and a percentage column is a common way to lose control of a product. What comes back is a technically different product made to someone else's defaults.
What a usable specification contains
Ingredient identity at grade and supplier level, not just common name, since grade changes behaviour.
Process steps in order, with temperatures, hold times, mixing parameters and the points at which the batch is checked.
In-process and finished-product tolerances: appearance, pH where relevant, viscosity, weight or fill, and the range considered acceptable.
Packaging detail, including component compatibility and fill target.
The testing plan and who performs it. Analytical work is coordinated through qualified third-party laboratories, and the specification should say what is tested, at what frequency, and against what limit.
Why it protects the brand
A written specification makes deviation visible. Without one, a batch that behaves differently is a matter of opinion; with one, it is a measurable variance against a defined range.
It also makes the product portable. A brand that owns its specification can move production without redeveloping the product.
