“…Other compounds with somewhat lower yields were nerol, carvacrol, allyl heptanoate, and italidione I (mw = 210) (78.7 mg/L, 78.3 mg/L, 73.1 mg/L, and 70.1 mg/L, respectively). Accordingly, Kunc et al [9] also reported 3-pentanone as one of the major compounds in immortelle hydrosol obtained from one and two-year-old immortelle plants grown in Slovenia (10.0 % and 7.4 %, respectively), but there were no other similarities in the major compounds compared to our sample. Other major compounds in this report were 2,2dimethylnon-5-en-3-one (8.8-13.0 %), 3-octanone (8.0-12.3 %) and α-terpineol (7.6-9.1 %), while in the observed Croatian populations 2,2-dimethylnon-5-en-3-one (14.69-18.40 %) and αterpineol (11.8-19.55 %) were listed as the major compounds.…”

“…[8] Although the chemical analyses of immortelle essential oil have been extensively and thoroughly reported, very few reports paid attention to the chemical composition of hydrosols. [9][10][11][12] The reason for this is probably that the preparation of samples for the chemical analysis of hydrosols is somewhat more difficult than the analysis of essential oils. [12] For quality analysis of hydrosols, nonpolar compounds that are dissolved to a low percentage are usually obtained by repeated liquid-liquid extraction (LLE) with nonpolar solvents of different polarity indices.…”

“…Among many other useful aromatic plant species, essential oil of immortelle ( Helichrysum italicum ) has found wide use in the cosmetic and perfume industry in the last decade due to its confirmed anti‐aging properties [8] . Although the chemical analyses of immortelle essential oil have been extensively and thoroughly reported, very few reports paid attention to the chemical composition of hydrosols [9–12] . The reason for this is probably that the preparation of samples for the chemical analysis of hydrosols is somewhat more difficult than the analysis of essential oils [12] .…”

Immortelle, a revered Mediterranean medicinal plant, is celebrated for its potent essential oil renowned in the cosmetic industry for its skin‐enhancing properties. Yet, immortelle hydrosol, an often‐overlooked byproduct, holds promise in cosmetics due to its compatibility with polar active ingredients. This study investigates the chemical composition of immortelle hydrosol by employing liquid‐liquid extraction (LLE) to transfer volatile organic components into nonpolar solvents. Four solvents – chloroform, dichloromethane, hexane, and benzene – were assessed through ten consecutive extractions from industrially produced immortelle hydrosol. Quantification was achieved using GC analysis with tetradecane as an internal standard. Chloroform emerged as the most efficient solvent, yielding 2447.0 mg/L of volatile compounds, surpassing benzene, dichloromethane, and hexane. Key compounds in immortelle hydrosol included 3‐pentanone, 2‐methyl‐1‐butanol, and γ‐terpineol. Importantly, the study revealed that a portion of essential oil compounds persists in the hydrosol even after ten LLE cycles, with optimal results achievable in five extractions (~92% in most cases).

“…Its main components are monoterpene limonene and sesquiterpene hydrocarbons such as α-pinene, α-cedrene, aromadendrene, and β-caryophyllene. 17,18 It is worth mentioning that in one of the reported cases, the patch test with the sesquiterpene lactone mix was also positive, indicating a possible sensitization through this component.…”

Objective To analyse the clinical characteristics and sensitivity of an essential oil patch test series (EOS) in patients sensitized to their own essential oils (EOs). Method We analysed the clinical data and patch test results obtained with the European baseline series (BSE) and an EOS, as well as the mode of use of EOs, through a questionnaire included in the patient file. Results The study included 42 patients (79% women, average age 50 years) with allergic contact dermatitis (ACD), 8 patients required hospitalization. All patients were sensitized to the EO they used, primarily lavender (Lavandula augustifolia, 8000‐28‐0), tea tree (Melaleuca alternifolia leaf oil, 68647‐73‐4), ravintsara (Cinnamomum camphora oil, 92201‐50‐8), and 2 cases were attributed to helichrysum (helichrysum italicum flower absolute, 90045‐56‐0). 71% had positive patch tests to fragrance mix I or II, 9 only to the EOS and 4 only with their personal EO. Interestingly, 40% of patients did not spontaneously mention the use of EOs, and only 33% received advice on their use at the time of purchase. Conclusion Patch tests with the BSE, limonene and linalool HP, and oxidized tea tree oil is sufficient to detect most EO‐sensitized patients. The most important is to test the patient's own used EOs.

“…In summary, the aforementioned oil possesses various properties such as anti-allergic, antibacterial and antiaging effects, making it widely used in the cosmetic industry. However, in order to transfer the essential oils to textile materials and ensure their long-lasting effectiveness, different methods need to be employed (Ghayempour and Montazer, 2016; Mehta and MacGillivray, 2016; Ghosh and Chipot, 2015; Kunc et al. , 2022).…”

PurposeThe aim of this study was to prepare antibacterial capsules and transfer them to cotton fabrics using the impregnation method.Design/methodology/approachFor this purpose, helichrysum oil was encapsulated by ß-cyclodextrin (ß-CD) using the kneading method at three different molar ratios. The products were then applied to 100% cotton fabric through the impregnation method.FindingsMorphological assessment showed that the inclusion complex had smooth surfaces and spherical shapes. Fourier transform infrared spectroscopy and differential scanning calorimeter analysis results confirmed the formation of the inclusion complex between ß-CD and the active agent at mole ratios of 1:1, 1:2 and 1:3 for helichrysum oil. According to the analyses, it was determined that the highest complexing rate was between 9.72% and 1:2 in capsules containing ß-CD:helichrysum oil and the sizes of particles which is 1:2 are determined to be between 2 and 25 µm. The presence of capsules on the fabrics was determined after 5 washing cycles. Antibacterial activity was evaluated against Staphylococcus aureus and Escherichia coli bacteria. The antibacterial analysis results showed that the inclusion complex provided a reduction of over 96% against both S. aureus and E. coli bacteria, and the fabrics exhibited antibacterial effects even after 5 washing cycles. The major constituents of the oil were decreased after 5 washes, but significant peaks were remained according to the gas chromatography analyses. These results indicate that helichrysum oil can be used for its antibacterial properties, and it has been observed that this activity continues up to 5 washes when transferred to the fabric in the form of an inclusion complex.Originality/valueAlthough helichrysum oil is widely used in cosmetics, there is a lack of studies on its application in textiles. Therefore, this study investigated the potential use of helichrysum oil, which has a wide range of applications, in textiles for its antibacterial properties through molecular encapsulation. The use of naturally sourced substances such as helichrysum oil in the textile industry can offer an environmental and sustainable alternative. This study can be considered as a step toward the development of innovative and naturally sourced antibacterial products in the textile industry.
