Fragrances

Posted on Sunday 30 August 2009

Fragrance has an immediate association with memory – so it can be important to choose the right one! Particularly when you are using your fragrance in a personal care product, you want to create the right theme for your product.

Perfumers select from numerous raw materials and ingredients to build a fragrance. They utilise natural ingredients (such as essential oils) and other fragrance compounds, combining and blending them in proportions to design new creations or match existing fragrance themes. Fragrances also have fixatives included in their formulation, which allows a longer lasting fragrant impact. They are created in such a way that only a small volume is required to create a powerful aroma.

All Auroma fragrances have been developed to comply with the IFRA (International Fragrance Research Association) standards. IFRA standards have been set to establish safe levels of ingredients in fragrance. These levels help to minimise sensitivity reactions, however, as every application is different, trials will need to be run for stability and sensitivity of your end product.

Candle & Soap Fragrances
 
When making your own soaps and candles it is important to use fragrances that are specially designed to blend well in that medium Standard fragrances are often unsuitable for candles and soaps as they will either discolour the recipe or “fall out” of the mixture, creating an uneven odour. This range of fragrances has been specially designed for soaps and candles. As every recipe/formula is different, we recommend that you produce a sample batch of soaps or candles to determine the exact suitability of the fragrance with your particular ingredients. Generally, dilution levels are 2-5% for candle and soaps, however if you want a stronger fragrance impact check for stability at higher dilution levels.
Method:

1. Place 300gm of Beeswax and 2 tablespoons of Stearic Acid in a microwave proof container. Microwave on high until melted (2-5 minutes). While wax is melting, string a length of wick to bottom hole of mould and secure with florist putty. Pull the wick quite taut and wrap around the skewer or dowel (rest skewer across the top of the mould).
2. Remove wax from microwave and give it a stir with a stainless steel spoon. Return to microwave for a further 1-3 minutes. When the wax is completely liquid, add 5-15mL of Candle Soluble Fragrance Oil and blend thoroughly.
3. Pour melted wax into moulds.
4. As the candle cools a depression will form around the wick due to the shrinkage.
5. After about an hour, puncture wax shell in three places about 200mm from wick with skewer. This releases any trapped air and results in a better burning candle. Reheat wax and fill the depression, but do not exceed the original level.
6. Allow to cool until set. Remove skewer from wick and trim wick.
