Material Monday Insight on Scent in Products: Injection Moulding Scent

Posted 6 November 2017 by Katie Kubrak

With scent being a super powerful sense, it could be used to create not only more memorable consumer experiences but also a more holistically refined perception of your brand. In effect, this week in “Material Monday: Series 2” we explore how scent could be injection moulded into any shape and form across a range of products.

Scent additive technology is ideal for moulding applications as it leaves an accurate and lasting branded scent of your product. This olfactory outcome is achieved through adding concentrated organic oil fragrances (carried in ethylene vinyl acetate (EVA) granules) to polymers during manufacture.

In production, scented masterbatch is combined with the polymer through the feeder just before the extrusion screw. This is done at a typical addition rate of 1% or lower, making it a cost-effective way to introduce a multi sensory experience to products. Nevertheless, some brands choose to add up to 5%.

Perfumed granules are white/translucent. The good news is that they will not impact the properties or colour of the main material. Furthermore, this technology offers off-the-shelf scents as well as flexibility of adding some of your brand’s signature scents.

Some of the readily available aromas include: Lime, Orange, Green Apple, Mango, Pineapple, Red Cherry, Raspberry, Strawberry, Blueberry, Coconut, Vanilla, Bakery & Cinnamon, Sweet Candy, Bubble-gum, Candied Fruit, Toffee, Malt, Coffee, Chocolate, Cucumber, Vanilla Honey & Hazelnut, Aniseed, Lavender, Night Jasmine, Orchid Lemongrass & Ginger, Spring/Summer Flowers, Fresh Cut Grass, Mint, Eucalyptus, Cedarwood, Sandalwood, Leather, Fresh Linen, Sunscreen, Pina Colada, Baby Lotion, Citronella and so the list goes on.

Current applications of the described technology include educational products for multi-sensory environments to stimulate children with learning difficulties and scented accessories to keep washrooms smell pleasant and fresh.

Opportunities behind this technology include adding a custom scent of your brand into injection-moulded products that will start to dissipate after 5 to 6 weeks. The brand benefit of this would be creating emotions of anticipation, engagement and excitement behind your customers’ perception of your products. This deep emotional bond could further translate not only into a more holistic awareness of your brand but also a long-term customer loyalty due to wish for a repeated olfactory experience.

If you would like to visit our Material Library and learn about scent-activating technologies, or you would simply like to visit our exhibition launched during London Design Festival 17 titled “London in Seven Scents”, which was released to coincide with “Perfume” exhibition at Somerset House and “Material Monday: Series 2”, please do not hesitate to get in touch.
