Fragrance Masterbatches

The fragrance oil is encapsulated and carried in a resin so it can be dosed as pellets at the machine. The encapsulation protects the volatile compounds through the melt stage, and the fragrance then migrates slowly out of the finished part in use. Without encapsulation, most of a raw fragrance oil would simply flash off in the barrel.

A correctly encapsulated fragrance masterbatch is designed to. Fragrance compounds are volatile, so the practical limit is set by your melt temperature and residence time — the hotter and longer, the more you lose. This is why fragrance works well in polyolefin injection moulding and extrusion, and is much harder in engineering polymer masterbatch at 280°C. Tell us your process conditions before we formulate.

It depends on the loading, the polymer, the part thickness and how the product is stored. Fragrance migrates from the bulk to the surface and evaporates, so a thicker part holds a reservoir for longer and a sealed pack holds it far longer than an open one. The only reliable answer is from a trial on your own part — which is why we send samples rather than quote a figure.

Yes. We hold a range of in-stock fragrance masterbatches and also develop custom-tailored scents to a brief or to a reference sample. Tell us the character you are after, or send the fragrance you currently use, along with the polymer and process.

Typically household goods products, cleaning and storage items, toys, stationery, cosmetics packaging and promotional items — anywhere the scent is part of how the product is experienced. It is also used in recycling masterbatch applications to manage residual odour from recycled material.

Suitability is decided grade by grade against the standard that applies to your product and market, and toys in particular carry their own safety requirements. Tell us the application and the standard you are working to and we will confirm what we can supply against it. See our toys page and our certifications.

It works best in the polyolefins — PE and PP — where processing temperatures are moderate, and is used in styrenics and flexible compounds. Higher-temperature engineering resins are more limited, for the volatility reasons above. Tell us the resin and we will say honestly whether it is a good fit.
