In most cases the demand cannot be provided anymore by natural sources. Therefore, a lot of fragrances, flavours and aromas are based on chemical compounds in the fragrance industry. An important class/category of compounds in this field are aldehydes and ketones. 

Rosemary oil is extensively used in cosmetics as a fragrance component and/or a masking agent. Products in which it is used include soaps, detergents, creams, lotions, and perfumes (especially colognes and toilet waters). Maximum use level reported is 1% in the last category. ... 

The history of monohydric alcohol-based ester-type plasticizers for polyvinyl chloride is reviewed, and a prediction of the future for these plasticizers in the eighties is made. Finally, although not in the large volume category compared to many monohydric alcohols, the rather sophisticated chemistry used to produce monohydric alcohols for the flavors and fragrance industry is covered. 

The structure/activity relationship (SAR) tools employed in odor research are essentially the same standard tools used in all applications, and the models developed fall into the categories of substrate and receptor models. The pharmaceutical industry is the leader in SAR techniques, and the fragrance industry tends to follow its lead. Early models were substrate based, but the discovery of the genes that code for the olfactory receptor proteins has also allowed receptor models to be constructed.
