To Determine The Amount of Flavor Oil Used In A Product:
The amount of flavor that should be used in a formulation depends on three factors:
1) The maximum amount of flavor the product base will accept.
2) The maximum IFRA skin safe level.
3) The amount of fragrance that smells good in your product.
You will look at these three maximum guidelines and use the LOWEST percentage.
Maximum Product Base Guidelines:
Lip Balm, Lip Scrub, Lip Butter, Lip Gloss: 10%
To Determine The IFRA Guidelines:
IFRA is a self-regulating trade organization that together with the industry's scientific center RIFM (the Research Institute for Fragrance Materials) establishes usage safety standards for materials that comprise fragrance and essential oils. Each year IFRA updates their standards based on sound science.
Wholesale Supplies Plus updates IFRA documents annually so that customers can stay up-to-date with the latest science. If you find IFRA levels have changed for your formula, it is standard to take 2 years to update products in the market.
Flavor oils that contain vanilla or vanillin will change color. The color change can take days, weeks, or months and can vary from a light ivory to dark brown.
