Capra, P. published the artcileWetting and adhesion evaluation of cosmetic ingredients and products: correlation of in vitro-in vivo contact angle measurements, HPLC of Formula: 70445-33-9, the publication is International Journal of Cosmetic Science (2017), 39(4), 393-401, database is CAplus and MEDLINE.

Objective : The aim of this work was to use the contact angle measurement in order to predict the behavior of ingredients and finished cosmetic products on skin to improve skin feel and product texture. Method : Different classes of cosmetic ingredients and formulations were evaluated. The contact angle measurements were carried out by the sessile drop method using an apparatus, designed and set up in laboratory Glass, Teflon and human skin were the reference substrates. In a preliminary phase, TEWL parameter, sebum content and hydration of human skin were measured to set up method. Results : Data demonstrated that glass substrate may be used as replacement of the skin:critical surface tension of skin and glass were about of 27 and 31 dyne cm^-1, resp. Non-ionic surfactant with increasing HLB was evaluated: a correlation between contact angle measured and HLB was not observed because of different and complex mol. structure. In detail, ethylhexyl hydroxystearate (θ_glass = 17.1°) showed lower contact angle value with respect to Polysorbate 20 (θ_glass = 28.1°). Sodium laureth sulfate and stearalkonium chloride were also evaluated: anionic mol. showed more affinity for glass with respect to Teflon (θ_glass = 21.7° and θ_Teflon = 52.3°). Lipids and silicones showed different affinity for substrate according to hydrophilic groups and hydrocarbon chain: contact angles of silicones remained unchanged independently from substrate. Finished cosmetic products (O/W, W/O emulsions, cleansing oil, dry skin oil) showed different profiles according to surfactant and its affinity for continuous phase of the formulation. Comparing the values of the contact angle on skin of non-ionic surfactants, as ethylhexyl hydroxystearate and Polysorbate 20, they showed values lower (near to zero) than ones of sodium laureth sulfate and Stearalkonium Chloride (21.7° and 66.8°, resp.). Finally, finished cosmetic products tested on human skin showed different profile: corresponded contact angle values were less than 20°. The product tended to be quickly adsorbed on human skin. Conclusion : Systematic study carried out by evaluating the wettability of single cosmetic ingredients on different substrates allowed to find correlations between the use of certain ingredients and the final performance of a cosmetic product.

Kluczyk, Alicja published the artcileArgireline: Needle-Free Botox as Analytical Challenge, Computed Properties of 70445-33-9, the publication is Chemistry & Biodiversity (2021), 18(3), e2000992, database is CAplus and MEDLINE.

Argireline-containing cosmetics attract public interest due to their confirmed reduction of facial wrinkles. Argireline is a peptide that works by inhibiting the release of neurotransmitters in the neuromuscular junction, producing a botox-like effect. Therefore, it is used as a safe needle-free alternative to botox treatment. In this work we investigated the presence of Argireline in cosmetic creams and sera by application of reversed phase liquid chromatog. and tandem mass spectrometry (RP-HPLC/MS and MS/MS). The anal. revealed the presence of argireline and its oxidized form in several different cosmetics. The methionine residue in Argireline sequence was indicated as oxidation point according to neutral loss MS studies. The developed sample preparation strategy minimizes and monitors methionine oxidation, bringing to our attention the question of impact of ingredients on the stability of cosmetic product.

Inman, Chiraporn published the artcileAlternative application approach on black bean: hair coloring product, Computed Properties of 70445-33-9, the publication is Chemical and Biological Technologies in Agriculture (2020), 7(1), 2, database is CAplus.

Abstract: Background: Black bean is one of the important beans as the second most consumed bean globally after soybean. It has been reported as a sustainable source of anthocyanins, important natural colorants used in food and consumer products. However, industrial uses of black bean anthocyanins in pharmaceutics and cosmetics have rarely been explored. Thus, here, a black bean anthocyanin extract was prepared, quality controlled and developed into an efficient hair coloring product. Results: Black bean was macerated in hydrochloric ethanol to produce a dark-reddish 1.85 ± 0.04% dry extract with total anthocyanin content (TAC) of 1.24 ± 0.48 μg/mL cyanidin-3-glucoside. The extract was readily dissolved in propylene glycol (25%), giving a reddish to red-brownish solution at pH of 4.00-7.00. The addition of antioxidant significantly (p = 0.000) enhanced the stability of the extract in an accelerated stability test (90.34 ± 5.32 from 67.83 ± 3.45% TAC remaining). Three base hair gels containing different thickeners were developed to yield clear gels with a viscosity of 101,666.67-447,333.33 cps and a pH of 4.80-4.97. The gel base with the best hair application properties was chosen to mix with 8, 10 and 12% black bean extract to produce similar visually assessed red-brown gels (L* = 33.25-33.76, a* = 0.06-0.09, b* = – 0.45-0.38 and h* = 277.54-283.31) at 73,733.33-99,666.67 cps and a pH of 5.00-5.01. All of the black bean hair coloring gels were stable under the accelerated test. The 10% hair gel was tested for its hair staining efficacy. The black bean hair coloring gel was found to efficiently color hair, and the color was maintained through four washings. Conclusions: An alternative application approach of using black bean as a natural colorant is presented here, including its basic requirements for preparation and quality control from an industrial aspect. The efficient semi-permanent hair coloring product containing black bean is an innovative natural product and is considered as one progress towards a sustainable bio-based economy using a readily available industrial crop, black bean.

Stanisic, Danijela published the artcileNew sustainable process for hesperidin isolation and anti-aging effects of hesperidin nanocrystals, Formula: C11H24O3, the publication is Molecules (2020), 25(19), 4534, database is CAplus and MEDLINE.

Hesperidin, a secondary orange (Citrus sinensis) metabolite, was extracted from orange bagasse. No organic solvents or addnl. energy consumption were used in the clean and sustainable process. Hesperidin purity was approx. 98% and had a yield of 1%. Hesperidin is a known supplement due to antioxidant, chelating, and anti-aging properties. Herein, hesperidin application to eliminate dark eye circles, which are sensitive and thin skin regions, was studied. In addition, the proposed method for its aqueous extraction was especially important for human consumption. Further, the most effective methods for hesperidin nanonization were explored, after which the nanoemulsions were incorporated into a cream formulation that was formulated for a tropical climate. Silky cream formulations (oil in water) were tested in vitro on artificial 3D skin from cultured cells extracted from skin residues after plastic surgery. The proposed in vitro assay avoided tests of the different formulations in human volunteers and animals. It was shown that one of the nanonized hesperidin formulations was the most skin-friendly and might be used in cosmetics.

In the 4-component system water/C₁₂H₂₅OCH₂CH₂SO₄Ca_1/2/C₄H₉CH(C₂H₅)CH₂O CH₂CH(OH)CH₂OH/C₁₀H₂₂ with 5 weight% total surfactant (surfactant + cosurfactant), 2 different microemulsion phases are formed when water and oil contents are both high, with only small differences in cosurfactant content. The structure of the microemulsions was investigated by the Fourier transform pulsed gradient spin-echo NMR technique and was found to be quite different (closed domains of oil in water, or water in oil, or bicontinuous) for different conditions (water-to-oil ratio, cosurfactant concentration). The microemulsion structure changes dramatically with small changes in cosurfactant concentration

Yamaguchi, Shigehiro published the artcileChanges of organized solution (microemulsion) structure with small change in amphiphile composition, Formula: C11H24O3, the publication is Yukagaku (1989), 38(2), 157-60, database is CAplus.

In the system of 8 weight% CaCl₂ aqueous/C₁₂H₂₅OCH₂CH₂SO₄Ca_0.5/iso-C₈H₁₇OCH₂CH(OH)CH₂OH/decane with only 3 weight% of total amphiphiles, it was possible to obtain only one phase region of microemulsion whose solvents swelled by 97 weight% (water + oil). The composition of water and oil varied over the entire range with slight changes in the amphiphile ratio from 0.38 to 0.42. Self-diffusion measurements indicated the microemulsion microstructure changed from O/W (hydrophilic) to W/O (lipophilic) by varying the HLB of the amphiphiles. A comparison of these results with change in temperature in a nonionic surfactant system showed that the change in the ratio of hydrophilic amphiphile and lipophilic amphiphile (from 0.38 to 0.42) had the same effect as that in HLB as making the temperature 30° in the nonionic surfactant system.
