What Makes For a Quality Fragrance Oil?

Use Candle Deli quality fragrance oils

How can you tell if a fragrance oil is worth buying?

This question could also be formulated as “why are some fragrance oils so expensive?”.     The short answer is “horses for courses”, which is just another way of saying you get what you pay for. Never is this more true than when it comes to fragrance oils.

Important factors to consider

  • the quality of the raw materials (both natural and synthetic);
  • legal requirements (certification and documentation);
  • consistency and concentration
  • intended application

Legal requirements

Is the fragrance IFRA certified? Is it skin safe? Is the correct dosage indicated? Are suitable applications indicated?


Will the fragrance I buy today smell exactly the same as the fragrance I buy in 10 years’ time? E.g. if you buy Sandalwood fragrance oil from Candle Deli today, it will smell the same as whatever you bought from us as Sandalwood 5 years ago.


Tip = look at indicated dosage levels. If 2% is indicated, then obviously this fragrance oil is far more concentrated than a fragrance oil where 6% dosage is indicated.

Intended Application

Quality fragrance oils are performance products.  That means that these fragrance oils are formulated to give specific results in a specific application.  For instance, Candle Deli’s Zesty Lemon fragrance oil was specifically formulated for cold process soap.  This fragrance will therefore bind well with soap batter, withstand an aggressive pH, tolerate high temperatures and provide a strong and long-lasting pleasant aroma when the product, in this case a bar of soap, is used.

A quality, well-formulated fragrance oil will often perform well in a variety of applications.  Not only does Zesty Lemon fragrance oil work well in cold process soap, it also works well in glycerine soap, paraffin wax and soy wax.   At Candle Deli we test each fragrance in our range in a variety of products.  The product description underneath each fragrance oil will tell you where and how to use each fragrance oil.
