Environmental Working Group (EWG) is writing to express deep concern that FDA officials are excluding public health, consumer, and environmental organizations from this meeting while allowing the regulated industry to participate. While such an unbalanced discussion of consumer safety issues is always unacceptable, this exclusion is even more problematic in light of our new analyses of product safety, which reveal that products sold in the U.S. frequently violate industry safety standards and contain ingredients banned in other industrialized countries. Our findings raise fundamental concerns about closed-door industry-regulator meetings that could further weaken international cosmetic policies. In a new investigation of the ingredients in more than 23,000 products, EWG found that nearly one of every 30 products sold in the U.S. fails to meet one or more industry or governmental cosmetics safety standards.

Further processing produces other ingredients including Hydrogenated Jojoba Oil, Hydrolyzed Jojoba Esters, Isomerized Jojoba Oil, Jojoba Esters, and Jojoba Alcohol. Synthetic Jojoba Oil also is used in cosmetics. In this group Simmondsia Chinensis (Jojoba) Seed Oil, the most widely used ingredient, and safe at concentrations up to 100% in body and hand creams, is expressed from seeds and is composed almost completely (97%) of wax esters of monounsaturated, straight-chain fatty acids and alcohols with high-molecular weights.

  • Transesterification of Jojoba Oil-Wax Using Microwave Technique Labiba I
    World Academy of Science, Engineering and Technology International Journal of Chemical and Molecular Engineering Vol:8, No:5, 2014 Transesterification of Jojoba Oil-Wax Using Microwave Technique Labiba I. Hussein, Maher Z. Elsabee, Eid A. Ismail, Hala F. Naguib, Hilda A. Aziz, Moataz A. Elsawy Biodiesel fuel has the potential to reduce the level of Abstract—Jojoba oil-wax is extracted from the seeds of the pollutants and the level of potential or probable carcinogens jojoba (Simmondsia chinensis Link Schneider), a perennial shrub that [2]. grows in semi desert areas in Egypt and in some parts of the world. Biodiesel is defined as “a fuel comprised of mono-alkyl The main uses of jojoba oil-wax are in the cosmetics and esters of long chain fatty acids derived from vegetable oils or pharmaceutical industry, but new uses could arise related to the search of new energetic crops. This paper summarizes a process to animal fats” [3]-[5]. Transesterification (also called convert the jojoba oil-wax to biodiesel by transesterification with alcoholysis) of triglycerides for biodiesel manufacture has ethanol and a series of aliphatic alcohols using a more economic and been extensively studied in the past few years [6]. The most energy saving method in a domestic microwave. The effect of time commonly used oils for the production of biodiesel are and power of the microwave on the extent of the transesterification soybean [7], [8], sunflower [9], [10], palm [11], rapeseed [12], using ethanol and other aliphatic alcohols has been studied. The canola [13], cotton seed [14], jatropha [15] and jojoba oil-wax separation of the alkyl esters from the fatty alcohols rich fraction has been done in a single crystallization step at low temperature (−18°C) [16].
