Hemp seed oil has a very better effect of sunscreen, repair, anti-allergy and anti-aging, as a result of which it is a high-quality raw material for skin care products. In this study, the oxidation degree of hot-pressed and cold-pressed hemp seed oil which was stored in five different environments, was evaluated. The results showed that the long-chain unsaturated fatty acids were oxidized. The oxidation products of hemp seed oil were analyzed by headspace solid-phase microextraction gas chromatography-mass spectrometry (HS-SPME-GC/MS) and high performance liquid chromatography (HPLC). All hemp seed oils which were stored at low-temperature protected from light and outdoor environment contained aldehydes, ketones, and alcohols, which have a negative impact on the health of consumers. Furthermore, hemp seed emulsion was prepared with different HLB values. After the 2 nd month, hemp seed oil emulsion exhibited a good stability without stratification.

Large-amount encapsulation and subsequent expressing are common characteristics for many biomedical applications, such as cosmetic creams and medical ointments. Emulsion gels can accomplish that, but often undergo exclusive, complex, multiple synthesis steps, showing extremely laborious and non-universal. The method here is simple via precisely interfacial engineering in homogenizing a nanoparticle aqueous dispersion and a polymer oil solution, gaining interfacial 45° three-phase-contact-angle for the nanoparticle that can bridge across oil emulsions’ interfaces and ultimately form interconnected macroscopic networks. Their bridged skeletons and rheology are tunable over a vast range and deterministic on the basis of components’ inputs. Furthermore, emulsion gels with high encapsulation and storage ability encapsulating active sunscreen ingredients, as a proof-of-concept, outperform commercial products. The ease (only seconds by strongly mixing two solutions) and the versatile chemical selection of our synthetic emulsion gels suggest an exciting general, scalable strategy for the next-generation cosmetic, ointment or otherwise food gel systems.

Hemp seed oil has good sun protection, repair, anti-allergy and anti-aging effects, and is a high quality raw material for the production of skincare products. However, the influence of surfactants and co-surfactants on the emulsification of hemp seed oil in aqueous solution has been rarely investigated. In this investigation, the surfactants and co-surfactants which were suitable for hemp seed oil emulsion were optimized, and the factors which influence the particle size and the stability of the emulsion were studied. Moreover, the application of hemp seed emulsion in different cosmetics was also further investigated. It was found that sorbitan monooleate/polysorbate-80 and glyceryl stearate were the most effective surfactant and co-surfactant in the emulsification of hemp seed oil. After three months the hemp seed oil emulsion had no layered separation and remained homogeneous at -48C, 258C and 408C. The water-resistant sunscreens and the hemp seed oil sunscreens were homogeneous pastes, had a soft texture and were stable at higher temperatures. No microorganisms were detected in these cosmetic creams. Therefore, hemp seed oil is suitable for sunscreen cosmetic materials.

Lignin is the most abundant natural phenolic polymer. However, the severe condensations of industrial lignin resulted in an undesirable apparent morphology and darker color, which hindered its application in the field of daily chemicals. Therefore, a ternary deep eutectic solvent is used to obtain lignin with light-color and low condensations from softwood. The results showed that the brightness value of lignin extracted from aluminum chloride-1,4-butanediol-choline chloride at 100 °C and 1.0 h was 77.9, and the lignin yield was 32.2 ± 0.6%. It is important that 95.8% of β-O-4 linkages (β-O-4 and β-O-4′) was retained. Lignin is used to prepare sunscreens and is added to physical sunscreens at 5%, with SPF up to 26.95 ± 4.20. Meanwhile, enzyme hydrolysis experiments and reaction liquid composition tests were also conducted. In conclusion, a systematic understanding of this efficient process could facilitate high-value utilization of lignocellulosic biomass in industrial processes.

Lignin contains benzene rings, carbonyl groups, and phenolic groups that serve as natural macromolecular UV absorber. However, lignin provides insufficient protection in the UVA region because it lacks a long conjugated structure. In this study, we propose a flavonoids-in-lignin coextraction strategy to improve lignin’s UVA protection performance. Flavonoids-containing lignin was isolated from Musa basjoo (Musa basjoo Siebold) and Moso bamboo (Phyllostachys edulis) leaves using l-cysteine (l-cys)-assisted extraction, and the contents of flavonoids in lignin could be further enhanced by employing non-dewaxed sources. Lignin’s UV-protective performance and antioxidant activity were improved as more flavonoids were reserved. Particularly, lignin isolated from non-dewaxed bamboo leaves (NBL) exhibited the best UV protection performance, achieving a sun protection factor (SPF) value of 40.99 with the addition of 5 wt % lignin into SPF 15 commercial sunscreen, representing a 143% enhancement, and a UVA protection factor (PFA) value of 12.17, reflecting a 109% increment. The sunscreens prepared from flavonoid-rich lignin maintained SPF values exceeding 30 and PFA values exceeding 9 (PA+++) even after 8 h of UV irradiation, indicating their long-term UV-protective properties. Furthermore, flavonoids-in-lignin coextraction demonstrated superior UV-protective performance compared to alkali lignin with adscititious flavonoid extracts. This study leverages the inherent advantages of natural plant cell wall components through a straightforward coextraction strategy, further unlocking the potential of lignin for sunscreen applications.

Requirements for safe, stable, and long-acting sunscreens are successfully accomplished by natural lignin due to its broad-spectrum ultraviolet (UV)-blocking and synergistic properties. Chemical sunscreens are encapsulated in enzymatic hydrolysis lignin (EHL) by a one-step high-intensity ultrasound method. Chemical sunscreen/EHL microcapsules were formed with 3 min processing, and the product could be stored without leaking for more than a whole year. Adding H2O2 increased the cross-linking degree of EHL on the surface of the capsules. When 5 wt % alkyl polyglucoside (APG) was added as surfactant, the size of capsules dramatically decreased to ∼100 nm and the ratio of EHL and chemical sunscreen reached 1:1, which significantly enhanced UV-blocking ability of the composites. Compared to the creams containing chemical sunscreen/EHL microcapsules and free chemical sunscreen, the sun protection factor (SPF) of the cream containing the same amount of chemical sunscreen/EHL nanocapsules increased 85% and 195%, respectively. The cream containing 10 wt % of UVA and UVB type chemical sunscreen coencapsulated nanocapsules gave SPF 408. Due to antiphotolysis protection of EHL, the SPF of the creams increased initially and was maintained for more than 8 h under UV radiation. There was no obvious leaking or permeation of chemical sunscreens from the capsules. The EHL-based capsules showed good biocompatibility.

In recent years, as the global climate continues to deteriorate, the harm of ultraviolet(UV) radiation to the human body is increasing, but the development of commercial UV-blocking products has not followed the corresponding update. Carbon dots (CDs) are excellent candidates for UV absorbers because of their multi-functional groups, high stability, and low toxicity. In this study, full UV bond absorbing CDs (3A-CDs) were synthesized by a one-step hydrothermal method using anhydrous Citric acid(CA) and 3-aminoquinoline as raw materials. The 3A-CDs have super high UV absorption efficiency, light-aging resistance, and acid and alkaline resistance. Subsequently, different concentrations of 3A-CDs were doped into PVA to prepare 3A-CDs@PVA films with excellent full UV bond absorption and good mechanical properties . Finally, 3A-CDs@PVA films were sandwiched between two pieces of transparent umbrella cloth. The 0.3 wt% 3A-CDs@PVA film with transparent umbrella cloth can achieve a blocking efficiency of more than 97.2% in the full UV bands. Also, SPF is greater than 50, PFA is PA++++, and the visible light transmittance is as high as 93.8%. This study provides a new application and prospect for the development of CDs and their composite products into new, efficient, and durable UV-blocking products.

TiO 2 is a typical anti-ultraviolet agent in sunscreen cream, but it suffers from a lack of anti-oxidant activity for scavenging reactive oxygen species. Other traditional sunscreen ingredients, such as C 60 and ferulic acid, have moderate antioxidant and UV protection capabilities, and the products do not provide further UV protection. Herein, titanium hydride (TiH 1.97 ) particles with dual functions of anti-oxidant and anti-ultraviolet are presented as an active material to remove the highly oxidizing and harmful hydroxide free radicals from the skin surface. Owing to the active hydrogen in TiH 2 , it shows great potential to eliminate hydroxyl radicals, and the rate is roughly proportional to the exposed surface area (50% /20 min). Together with the biocompatibility of the in situ formed TiO 2 , which has a strong ability to absorb ultraviolet light during OH radical scavenging. At the same time, adding titanium hydride to sunscreen also enhances sun protection. The SPF value of sunscreen containing 1% titanium hydride and 20% titanium dioxide can reach 31.8, which exceeds the 20% titanium dioxide (15) by more than twofold. Therefore, titanium hydride with anti-ultraviolet and antioxidant functions can be regarded as a promising and safe ingredient for sunscreen cream.

Lignin has potential to serve as promising sunscreen agents as it has good ultraviolet (UV) absorption and antioxidant properties. However, the weak absorption capacity of lignin in the long-wave UV region (UVA, 320–400 nm) limits its further development. In this work, a spiropyran-modified lignin (DLSP) with photo-responsive property was prepared by in-situ construction of spiropyran (SP) structure in the demethylated lignin (DL). Due to the presence of SP moiety, the absorption of DLSP in the UVA region was significantly improved. Under UV irradiation, its absorption peak was redshifted as unconjugated SP form isomerized to conjugated merocyanine (MC) form, and the UVA/UVB ratio increased from 0.62 to 0.74. The free-radical scavenging ability of lignin could protect SP from photodegradation , which provided DLSP excellent fatigue resistance. DLSP were blended into creams to investigate its sunscreen performance. Results indicated that DLSP exhibited radiation-enhanced sunscreen performance, the sun protection factor (SPF) of cream containing 10 wt% of DLSP improved from 20 to 67 after 8 h of UV irradiation. Moreover, DLSP showed low skin penetration and good biocompatibility. These results provide a useful guideline for the rational design of sunscreens with special functionalities.

The active ingredients most commonly employed in sunscreens are compounds containing one or two aromatic rings. Lignin is the most abundant renewable aromatic polymer that has the potential to yield low molecular weight aromatic chemicals when strategically depolymerized. Here, the UV absorbance of a series of monomeric and dimeric lignin model compounds (LMCs) were studied. Specifically, vanillin and ferulic acid demonstrated good absorption in the UVB (280–320 nm) range, while the 5–5 dimer showed efficient absorption in the UVA (320–400 nm) range. Based on this, vanillin, ferulic acid and 5–5 dimer were mixed in pairs and dispersed in the oily isoeugenol to prepare LMC hybrid dispersions. Subsequently, demethylated lignin (DL) was synthesized and used to encapsulate the LMC hybrid dispersions via ultrasonic cavitation to prepare DL-based nano-capsules (DLNCs). The DLNCs were used as the only active ingredient in sunscreens, whose sun protection factor (SPF) value could be up to 55 with a dosage of 10 wt%. Due to anti-photolysis property of DL, the SPF value of DLNCs-based sunscreens increased initially and maintained >8 h under UV irradiation. Additionally, the prepared DLNCs exhibited excellent anti-permeability, antioxidant capacity and biocompatibility, making them a potential substitute for conventional petroleum-based sunscreen agents.

Organic ultraviolet filters (OUVFs) have been widely used as functional ingredients of sunscreen products and have entered into marine ecosystems, particularly in tropical areas where solar UV radiation is strong. These chemicals, with their potential toxicity and ecological risk, have raised widespread concern for the protection of the fragile marine ecosystem of coral reefs. In this study, fourteen OUVFs were analyzed among 24 coral species, together with their habitats including seawater and sediment from the coastal coral reef regions of Hainan Island, South China Sea. Surprisingly, all of fourteen OUVFs were detected in each sample, indicating the wide distribution of OUVFs among sites and samples. Among the fourteen OUVFs, benzophenone-3 (BP-3) and 4-methylbenzylidene camphor (4-MBC) were the most abundant, with concentrations ranging from 35.3 to 75.6 and 38.3 to 61.4 ng/L in seawater, from 13.2 to 25.9 and 7.0 to 17.4 ng/g dw in sediment, and from 4.5 to 21.3 and 4.4 to 19.7 ng/g dw in corals, respectively. Analysis of OUVFs in 24 coral species pointed that OUVFs accumulation in corals is morphology dependent: the highest concentration of OUVFs was identified in Galaxea fascicularis with abundant of polyps and tentacles while the lowest levels of OUVFs were found in Porites mayeri (smooth or lobed surface). In corals, we found that these OUVFs accumulated, depending on the coral species and the types of OUVFs. The ecological risk assessment further indicated that BP-3, 4-MBC and BP-8 had posed risks to corals. In addition, significantly higher concentrations of OUVFs were observed in Sanya (a seaside tourist resort) than in the other sites, suggesting that tourist activity and use of sunscreen products are the key to high inputs of sunscreen agents into marine ecosystem. Overall, our study demonstrates a potential risk role for OUVFs in coral protection in tropical areas where coral bleaching events occur.
