Do you provide samples?

When requesting samples, it is important for Carvansons Ltd to know the products and potential future products the aromas will be used in, along with the dosage levels you aim to work at. Furthermore, if you can advise on any legislative and formulation preferences you would like the formulations to conform to, we can keep this in mind whilst formulating and selecting.

 Frequently Asked Questions – Fragrance Development and Manufacturing

Fragrance manufacturing

How much fragrance oil should I add to my products?

All products have different fragrance requirements and thresholds. It is worth taking your time and testing different dosages of the fragrance in your product. All fragrances supplied by Carvansons LTD are issued with IFRA Conformity Certificates, this is an extremely important document when deciding on your fragrance dosage as it will advise what level you can safely use the aroma up to in different product categories. Please note the IFRA certificate does not advise an actual dosage you should be using but just a maximum safety limit.

A large aspect of dosage is down to your personal preference, cost and the amount of aroma your base can hold. If your base has a smell to it, you may find you have to add a higher dosage of aroma to cover the smell of the base before getting the benefit of the aroma.

There is an optimum limit with fragrances where no further benefit can be added from increasing the dosage. In fact, overdosing could cause issues with your product’s manufacture and functionality.

For further information on recommended dosage levels for specific products, please don’t hesitate to get in touch.

Can I mix fragrance oils together?

Yes, blending fragrances together is a great way to create new scents. We can advise on how this can be done safely and to the best effect. Please note any amendments to formulations will require reassessments and technical documents.

How can I describe my fragrance?

Carvansons Ltd can offer fragrance triangles upon request of any fragrances and can also advise essential oil contents to use in your own marketing.

What is a fragrance flashpoint?

The flashpoint of a fragrance is the temperature at which it becomes combustible if exposed to a spark or flame. The flashpoint for each fragrance is located on the CLP Safety Data Sheet under Section 9. Physical and Chemical Properties. Should you require testing at a specific temperature, we can help test this for you.

How long will a fragrance oil last?

We normally advise a shelf life of 18 months* for fragrances as long as they are kept in a cool, dry place, out of direct sunlight and headspace is kept to a minimum. We would recommend that you are using the fragrance oil to decant the aroma into smaller containers to limit the headspace and reduce oxidisation. For more information about this please contact our team.

*Please note although the shelf life is 18 month, we advise using your fragrance within 12 months to ensure you get the best impact from it.

How do I know if your fragrance is safe to use?

We are a member of the International Fragrance Association (IFRA) and comply with all regulatory requirements. We apply the IFRA Code of Practice to the manufacturing of fragrance and conform to COSHH and CLP for the handling of all fragrance materials.
