The Science Behind Fragrance Formulation


Fragrance formulation is a delicate process that brings your scents into a sellable form. For formulators, this means taking your oils and carefully converting them into finished products. But what’s the science behind it, and what does the process involve?

At Fillcon, we offer the full package for fragrance formulation, helping you get your scents to the shelves. In this article, we’ll discuss what fragrance formulation is, what ingredients may be involved, and how the fragrances and packaging are combined and tested to ensure the highest quality result.

What is Fragrance Formulation?

Fragrance formulation is the process of mixing scented oils together with other chemicals like alcohol and water. The original scent, which will have been produced by a specialist facility according to your specifications, will be combined with these products to the concentration you desire.

Depending on the ratios of the ingredients used, your fragrance’s intensity can vary greatly. Additionally, high quantities of alcohol in the process could result in products unsuitable for sensitive skin. As such, ensuring you work with a reliable partner who can work to your requirements – and has the knowledge to inform you on industry best practice – is essential to obtaining the best final result.

Just like the creation of your base fragrance, fragrance formulation also requires specialist equipment to achieve the best mix. Likewise, having access to filling facilities will also mean easier packing for the final product, enabling a smooth transition to distribution.

At Fillcon, we have all the tools and resources you need to acquire a quality product. From formulation to filling and packaging, we offer a comprehensive service that gets your scent out on the market.

Key Ingredients Used in Perfumes

Perfumes themselves are made up of a wide range of scents, chemicals, and natural products. Organic brands will want to stay away from man-made, factory-produced chemicals, but there are plenty of options around that are suitable for human use.

When a perfume is created, it is made in the form of an oil. This oil will be too strong in scent to be used, and too expensive for businesses to sell and consumers to buy. To make the final product, fragrance formulation is needed, which generally involves two key ingredients: alcohol and water.

Depending on the ratios you use, your perfume can be classed in one of the following ways:

  • Eau Fraiche: 1-3% perfume oil
  • Eau de Cologne: 2-5% perfume oil
  • Eau de Toilette: 5-15% perfume oil
  • Eau de Parfum: 10-20% perfume oil
  • Extrait de Parfum: 20-40% perfume oil

However, what’s most important is a rigorous mixing and testing process that ensures a consistent, high-quality final result.

The Process of Mixing and Testing Fragrances

Overall, the process of mixing fragrances is quite simple. It generally involves using a sanitised industrial mixer, which uses large blades to push the perfume oil, alcohol, and water around until a consistent mix is achieved.

It’s important for this process to run as long as it needs, as without adequate mixing your perfume might be of lower quality, or otherwise be unfit for use. Other factors like exposure to air and bacteria, temperature, and moisture levels must all be monitored and maintained to prevent product contamination or damage. Utilising a service with an exclusive warehouse and high-end mixing equipment (like we have at Fillcon!) will help you ensure the best results.

The next step is to test the product, identifying whether there’s any issues and confirming it’s fit for sale.

Ensuring Consistency and Quality in Fragrance Formulation

At Fillcon, we run a rigorous testing process for all of our products. We pride ourselves on the internal documentation and tracking we do for every batch of perfumes or other products that we fill, meaning we can track issues down to the item number and easily learn what went wrong.

For perfumes, our testing process ensures a consistent mix that’ll deliver a great result with every use. We also check things like the amount of fluid being filled into each container, and stay in close contact with you to make sure we’re meeting your expectations. In these cases, we might recommend you fill to full so that the customer gets a more satisfying end product, but will always make sure to keep you informed of the impact this could have on the overall number of products you can distribute.

Overall, to ensure a consistent and quality fragrance, your formulation process needs to be secured – and working with us could be the solution you need.
