“…Furthermore, Neves et al . (2019) studied the composition of rosemary essential oil and found α‐pinene (8%), 1,8‐cineole (34%) and camphor (52%) as the principal constituents. These results are in agreement with those found in this work, however, with different percentages for the principal constituents.…”

The effective control of an insect pest such as Drosophila suzukii (Diptera: Drosophilidae) has been challenging because its attack on red fruits can cause losses in production of up to 80% worldwide. The objective of this work was to extract and characterise the essential oil from rosemary (Rosmarinus officinalis), produce and characterise nanoparticles incorporated with this essential oil, evaluate the in vivo insecticide activity of free and nanoencapsulated essential oil against D. suzukii, and evaluate the effect of that oil on the enzyme acetylcholinesterase. The nanoparticles produced with the essential oil from rosemary had a particle size and surface charge of 236.6 nm and À11.8 mV, respectively. According to the FTIR data, the essential oil was incorporated into the polymeric matrix of poly(ε-caprolactone). Through in vivo toxicity analysis, the free and nanoencapsulated essential oils were found to possess insecticidal activity, with an LD 50 close to 9.1 g/L. The maximum anticholinesterase activity for the essential oil was 75% at a concentration of 0.10 mg/mL. The incorporation of the essential oil from R. officinalis into biodegradable nanoparticles of poly(ε-caprolactone) potentiated and prolonged its in vivo insecticidal activity against D. suzukii.

“…In addition, the microencapsulation of its essential oils protect said oils from degradation and evaporation and, at the same time, subjects them to a controlled release [72]. The synthesis of terpolymeric capsules containing the essential oil of Rosmarinus officinalis is also being worked on, with the aim of using it as an antifungal component in cosmetics [73].…”

Rosmarinus officinalis L. (Rosemary): An Ancient Plant with Uses in Personal Healthcare and Cosmetics

2020

This work is a bibliographical review of rosemary (Rosmarinus officinalis) that focuses on the application of derivatives of this plant for cosmetic products, an application which has been recognized and valued since Ancient Egyptian times. Rosemary is a plant of Mediterranean origin that has been distributed throughout different areas of the world. It has many medicinal properties, and its extracts have been used (mainly orally) in folk medicine. It belongs to the Labiatae family, which contains several genera—such as Salvia, Lavandula, and Thymus—that are commonly used in cosmetics, due to their high prevalence of antioxidant molecules. Rosemary is a perennial shrub that grows in the wild or is cultivated. It has glandular hairs that emit fragrant volatile essential oils (mainly monoterpenes) in response to drought conditions in the Mediterranean climate. It also contains diterpenes such as carnosic acid and other polyphenolic molecules. Herein, the botanical and ecological characteristics of the plant are discussed, as well as the main bioactive compounds found in its volatile essential oil and in leaf extracts. Afterward, we review the applications of rosemary in cosmetics, considering its preservative power, the kinds of products in which it is used, and its toxicological safety, as well as its current uses or future applications in topical preparations, according to recent and ongoing studies.
