PLM for flavour and fragrance manufacturers

What is different about flavour

Flavour and fragrance houses sell to other businesses. Their product is a concentrate that ends up inside a customer's drink or shampoo, so their PLM records serve a different purpose. A brand owner's system follows one finished product to the shelf. A flavour house follows one concentrate into dozens of customer products, each with its own dose and rules for its market.

The same lemon flavour used at a low dose in a soft drink and at a high dose in a boiled sweet leads to two separate compliance results. Both have to come from one master formula. Before you look at any demo, check whether the system lets one formula carry more than one application dose. CPG systems assume that one formula equals one finished product, and that assumption breaks the flavour house model on day one.

Nested formulas

Flavour and fragrance companies manage nested formulas by giving every base and accord its own versioned formula, as they do for other intermediates. That formula is then called as an ingredient one level up, and the PLM breaks it down to raw materials when a calculation needs it. A strawberry flavour uses a fruity ester base. That base uses a natural extract with its own constituent profile. If you change the base, every flavour that calls it changes too.

So a where-used search matters more here than in most industries. Before a perfumer edits an accord, they need to see every live fragrance that calls it and every customer who has approved one of those fragrances. The constituent profile of lemon oil shifts with harvest and origin, so each natural needs a stated typical composition and a rule for which version a calculation uses.

The most expensive mistake happens during data migration. Teams flatten intermediates into one long ingredient list to save time, and the links are lost. After that, every change to a base becomes a manual edit across hundreds of formulas. Check how deep the nesting goes in each candidate system and whether you can freeze an intermediate's version for a formula the customer has already approved.

Commercially sensitive formulas

A flavour or fragrance formula is the company's main asset, so the PLM has to protect it as a trade secret. Houses rarely patent formulas, because a patent publishes the recipe. Protection comes from controlling who sees which fields.

Inside the business, role-based controls let a perfumer see the full formula with percentages, while a salesperson sees the name and the price. The plant works from a coded manufacturing sheet that lists the steps without the creative logic behind them.

Access control needs to work at field level. Hiding a whole record is easy, but hiding percentages while ingredient names stay visible is harder, and that's the setting the business needs. Then test the exports. A report or spreadsheet download that ignores the screen's permissions is a common gap, and it's the one auditors find first.

Multi-level composition

Multi-level composition is the PLM's ability to break a formula down through every nested level to single chemical substances. The system then adds up how much of each substance reaches the customer's product. Every regulatory document the house issues depends on this calculation.

Take citral. It can enter one fragrance through lemon oil and through a lemongrass extract, and the allergen statement needs the sum of both. The IFRA Standards work the same way. The 51st Amendment merged the old annexes on natural complex substances and Schiff bases into one annex called Contributions from other sources, which means contributions hidden in naturals count toward the limit.

Carriers and solvents also count, as do known impurities, and systems differ on whether they include these automatically. Before go-live, take one formula your regulatory team has already calculated by hand and run it through the system. If the totals don't match, find out why before anyone trusts the output.

Restricted disclosure

Restricted disclosure means the flavour house gives each customer what it needs to comply and keeps the formula itself private. The customer receives certificates and declarations. The Handcrafted Soap and Cosmetic Guild, a trade body for small cosmetic makers, describes the IFRA certificate this way: it will give you the maximum usage levels for each product category, and listing the restricted components "is optional."

Food labels allow the same privacy. In the US, 21 CFR 101.22 lets a food label declare flavour simply as "natural flavor" or "artificial flavor." The PLM has to produce every disclosure document directly from the formula.

• Allergen declarations. at the customer's dose
• IFRA certificates of conformity.
• Safety Data Sheets (SDS).
• Dietary statements. such as halal, kosher or vegan
• Regulatory status letters. for each target market

Check that the system calculates each document and that each one is tied to the formula version that shipped. A typed declaration falls out of date as soon as the formula changes.

What regulations apply

The rules that apply depend on where the concentrate ends up. Food flavours fall under food law, and fragrances fall under cosmetics law plus the industry's IFRA Standards. A house that supplies both has to run both sets of rules from one data model.

Restrictions in the 51st Amendment applied to existing creations from 30 October 2025, which tested systems because every live fragrance needed rechecking. The EU allergen list applies to new cosmetic products from 31 July 2026. Ask each vendor who maintains the regulatory lists inside the product, and how fast an amendment reaches your system.

Which PLM fits flavour houses

The right PLM for a flavour house is a process-industry system with a strong formula engine. Discrete-manufacturing PLM, built around CAD parts and engineering bills of materials, doesn't fit this work.

Fragrance formulation management

Fragrance formulation management software is the part of the PLM where the perfumer works. It builds and versions trials, with checks against IFRA limits for the target product category as the perfumer works. It keeps the trial history behind every approved fragrance.

The category check matters because one fragrance can pass in one product type and fail in another. The European Commission's scientific committee on consumer safety (SCCS) reported upper use levels for citral of 0.05% in deodorants and 0.63% in hydroalcoholic products such as eau de toilette. A perfumer who writes a fine fragrance and later adapts it for a deodorant has to know at once which materials to cut.

Check when the warning appears. Software that flags a breach as the perfumer edits saves days of rework compared with software that only checks at release.

Working with flavour houses

If you buy flavours or fragrances, your own PLM has to hold each one as a sealed record with declared properties. You can store the supplier's data on allergens at your dose and IFRA maximum use for your category. The record can also hold the supplier's regulatory status and dietary claims.

Annel, a UK cosmetic compliance consultancy, lists what each fragrance supplier must provide under the new allergen rules. The list starts with a declaration covering all 80 allergens and an IFRA certificate under the 51st Amendment. Ask for a version number on every declaration. When the house reformulates after an amendment, your record should show that the data changed, and it can only do that if the supplier documents carry versions.

What to do next

Pick your hardest real formula, the one with the deepest nesting and the most customer versions, and run it end to end in every system you're considering. That single test shows how well each one handles nested formulas while it protects confidentiality and produces disclosures. Before you select, decide who in your business owns the composition data for naturals. No PLM for flavours and fragrances can calculate from data nobody maintains. C+P Consulting's small senior team works on site with ingredients manufacturers and manufacturers in the food and beauty sectors. It supports PLM selection and blueprinting. Its work also covers implementation and data migration. Talk to us about your programme.
