The cosmetics industry has been forced to search for new active chemicals as a result of increasing customer demand as well as stricter international regulations. Botanical extract offers a source of new active chemicals that is nearly endless and may be used to make cosmetics. Due to their olfactory character in the creation of fragrances and perfumes and the many beneficial properties of their individual components (EOCs), essential oils (EOs) are becoming increasingly popular natural ingredients in the cosmetics and toiletries industry. These properties include anti-inflammatory, antimicrobial, and antioxidant properties (e.g., moisturizers, lotions and cleanser in skin care cosmetics; conditioners, masks or antidandruff products in hair care products; lipsticks, or fragrances in perfumery). It is difficult to generalise the possible applications of essential oils in cosmetics and toiletries because each essential oil has its own unique chemical profile, which is connected with its own particular collection of benefits. Instead, formulators need to make an effort to discover acceptable mixes of essential oils or essential oil compounds in order to get the results they want from the completed goods. This paper presents a detailed examination of the existing research on the usage of essential oils and essential oil compounds (EOs and EOCs) in the cosmetics sector. In addition, we will focus on a few critical topics regarding the safety of essential oils and essential oil compounds used in the cosmetics sector. When formulators of cosmetics are working to perfect products that are based on botanical extracts, they are very likely to find the information offered in this review to be valuable.

Linalool (3, 7-dimethylocta−1,6-dien-3-ol) is an acyclic tertiary monoterpene alcohol that is present naturally in almost all essential oils in varying concentration degrees. 1,2 It is utilized generally in perfumery and many flowery fragrance compositions for fruityfresh odours such as neroli, lavender, and lily of the valley. 3 Linalool was included in the list of class "A" substances due to its usefulness as primal matter for the synthesis of high-value added compounds, such as their ester derivatives, 4,5 especially the acetate form. 6,7 Unlike linalool, linalyl acetate is also used as safe flavour adjuvants in food industries due to their high stability and low toxicity and in addition to their pharmacological properties such as antioxidant, antibacterial, or anti-inflammatory activities. [8][9][10] Linalool exists naturally as two isomeric forms, the 3R-(−)-linalool called licareol (odour threshold 0.8 ppb) that has a lavender or lily-of-the-valley odour and the dextrorotatory isomer is 3 S-(+)-linalool called coriandrol (odour threshold 7.4 ppb) that has a herbaceous and musty green smell 11 Licareol is the most common isomeric form; both enantiomers are available in nature, and the stereoisomeric composition of this alcohol influences the olfactory properties of the essential oils containing it. 4,5 For example, the enantiomeric distribution of (R)-(−) and (S)-(+) forms of linalool and linalyl acetate are important indicators of lavender oil purity. 12 Traditionally, monoterpene esters are obtained by conventional chemical synthesis or by extraction from plants. 13,14 However, the extraction and purification way remains less viable due to the large amount of raw material needed, high costs, and the smaller essential oil yield to meet the high industrial demand, 15 while the chemical ways use harmful reagents and causing environment pollution. 16,17 To circumvent those disadvantages and according to the increase demand for greener, environment-friendly processes, biocatalysis seems the ideal

A statistical approach was successfully applied to optimize the acylation of l‐menthol 1 in the presence of natural kaolin as an eco‐compatible catalyst. The influence of the main variation of the operating parameters, namely solvent volume, amount of the acyl donor, temperature and the catalytic rate of kaolin, was studied. A full factorial design (FFD) was used to search for the optimum of each parameter affecting the evolution of l‐menthol 1 acylation. A quadratic polynomial regression model was applied to analyse the experimental data with a p‐confidence level <.05 (95%). Statistical analysis of the data confirmed that temperature (T), acyl donor/acceptor ratio (Qa), kaolin mass (Qc) and solvent volume (V) were the significant factors affecting the l‐menthol catalytic acylation process. The determination coefficient of the adopted model was in the order of 98%. A set of optimal reaction conditions was established, and experimental tests were performed to validate the optimal conditions; the threshold of 100% was reached. Monitoring the kinetic profile of the reaction by gas chromatography (GC) showed complete conversion after 30 min of reaction. An upgrade of this developed environmentally benign process was applied to some monoterpenic alcohols, and the corresponding acetates were yielding at 45%–90%.
