What Is It?
Linalool is a colorless to very pale yellow liquid with a floral smell similar to that of bergamot oil and French lavender. It is a naturally occurring substance that is used to make fragrances and flavors. In cosmetics and personal care products, Linalool is used in the formulation of aftershave lotions, bath products, bubble baths, cleansing products, hair care products, lipsticks, moisturizers, perfumes and colognes, shampoos, skin care products and suntan products.
Why is it used in cosmetics and personal care products?
Linalool functions as a fragrance ingredient.
The Food and Drug Administration (FDA) includes Linalool on its list of substances considered Generally Recognized As Safe (GRAS) as flavoring substance. The safety of Linalool has been evaluated by the Research Institute for Fragrance Materials Expert Panel (REXPAN). Based on this evaluation, an International Fragrance Association (IFRA) Standard has been established. The IFRA Standard restricts the use of Linalool in fragrances because of potential sensitization.

The Cosmetic Ingredient Review (CIR) defers review of individual fragrance ingredients to the IFRA program unless the ingredient has significant uses other than as a fragrance. In this case, the ingredient may be assessed by both the CIR Expert Panel and REXPAN.

The Joint FAO/WHO Expert Committee on Food Additives (JECFA) concluded that Linalool does not present a safety concern at current levels of intake when used as a flavoring agent.

The Flavor and Extract Manufacturers Association Expert Panel has reviewed the safety of linalool and determined that it is Generally Recognized as Safe (GRAS) for use as a flavoring substance. In Europe, Linalool is included on the list of "allergenic" substances. The European Cosmetics Regulation requires manufacturers of cosmetics and personal care products to indicate the presence of certain "allergenic" substances in the list of ingredients if they are present above certain levels in the product (see Annex III). The presence of Linalool must be indicated in the list of ingredients when its concentration exceeds: 0.001% in leave-on the skin products 0.01% in products that are rinsed off the skin
