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.

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.

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.

A novel ultraviolet (UV) absorbing microcapsule was fabricated, featuring core–shell structures with triazine compounds as the inner core while water soluble polymers as the encapsulant shell. The composition and morphology of the microcapsules were optimized. Both encapsulation efficiency and load rate were analyzed. The encapsulation endowed with not only well aqueous dispersion, but also synergistic UV absorption capability. The application in sunscreen was demonstrated. Comparative studies were performed on the sun protection index of the creams, such as sun protection factors (SPF) and protection factor of UVA (PFA). Furthermore, the encapsulation enhanced the maintenance in aging measurements.

To reduce the cellular components damage and marine ecosystem pollution caused by common chemical sunscreens, natural or biologically derived sunscreen ingredients have become one of the major priorities, due to their effective protection against ultraviolet (UV) radiation while minimizing potential health risks. Herein, we develop a novel sunscreen agent, shellac, that is refined from biological sources with good biocompatibility and amphiphilicity. Shellac was first modified with natural source materials through amidation reaction, dextran (DEX), coumarin (CM) or cinnamic (CA), in which the former provided the hydrogen-bonding interaction, and the latter two provided UV absorption performance. The structures of these modified products were confirmed by X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier Transform Infrared (FTIR) and Proton Nuclear Magnetic Resonance ( 1 HNMR). Then, a plant sunscreen, sinapic acid (SA) was encapsulated into modified shellac nanoparticles (MSNPs), which showed uniform spherical structure observed by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and Zeta potential and nanoparticle analyzer, and the resultant MSNPs were further blended with sunscreen cream matrix. The sunscreen cream showed good enhanced UV-absorption capacity, and the Sun Protection Factor (SPF) increased to above 50. In addition, FTIR and UV-Vis absorption spectra were carried out to explore the possible synergistic effect between functional shellac, SA and sunscreen cream matrix. The obtained MSNPs also have superior biosafety according the cytotoxicity test, which makes them an ideal skin sunscreen agent.

In this work, a series of new lignin-graft copolymers were successfully prepared through enzymatic hydrolytic lignin (EHL)-initiated ring-opening alternating copolymerization of 3,4-dihydrocoumarin (DHC) and epoxides (EPO) through organocatalysis. A series of EPOs, including styrene oxide (SO), propylene oxide (PO), cyclohexane oxide (CHO) and lignin-derived-2-(2-methoxy-4-methyl-phenoxy) (MPO), together with DHC, were selected as model compounds to prepare EHL-g-P(DHC-alt-EPO), demonstrating the tailor-made potential of this synthetic protocol. The reaction conditions were optimized and the structures and thermal properties of EHL-g-P(DHC-alt-EPO) were fully elucidated by 1H, 13C and 31P NMR, FTIR spectroscopy, MALDI-TOF MS and GPC, DSC, and TGA. It was found that EHL-g-P(DHC-alt-SO) with a monomer conversion of 81.52%, DP of 3.21 and Mn of 62.9 kDa was prepared at a molar ratio of 5 : 5 : 1, 140 °C and 24 h. The UV shielding properties, antioxidant activity and biocompatibility of the as-prepared EHL-g-P(DHC-alt-EPO) was systematically evaluated. As a ‘proof of concept’ application, the potential of EHL-g-P(DHC-alt-SO) as an active ingredient in sunscreen was demonstrated, and a high sun protection factor (SPF) of 22.42 was achieved at 5 wt% dosage of EHL-g-P(DHC-alt-SO) in the cream, and the possible mechanism for the outstanding performance is also discussed.

Conventional lignin, a dehydrogenated polymer derived primarily from hydroxycinnamic alcohol monomers, exhibits relatively low antioxidant and ultraviolet (UV)-blocking activities due to its structural imperfection. Herein, we demonstrated that the dehydrogenated polymer of ferulic acid (an unconventional lignin precursor) (FAL) had excellent antioxidant and UV-blocking properties. Structural characterization showed that FAL contains abundant dihydrobenzofuran and butyrolactone structures, free phenolic hydroxyl groups, and cinnamic acid end groups. Such structural characteristics endow FAL with much higher antioxidant activity and broader and stronger UV absorptivity (especially UVA) than conventional lignins. Our investigation showed that FAL could significantly improve the UV-blocking property of commercial SPF30 and SPF50 and render a relatively light color. These versatile properties make the FAL a potential ingredient for application in sunscreen products. This work is enlightening not only for exploring better antioxidant and UV-blocking polymers from the dehydrogenated polymers of phenolic compounds but also for biosynthesizing more advantageous lignin in plants.

The escalating UV exposure has emerged as a significant threat to human health, manifesting in both acute and chronic health impairments. To mitigate these risks, a biosafety sunscreen cream was prepared for UV protection and moisturization. TiO 2 nanoparticles (NPs) were sequentially coated with Al(OH) 3 and chemically grafted with hyaluronic acid (HA) to produce TiO 2 - g -HA NPs. The optimized TiO 2 - g -HA 0.1 NPs achieved a grafting efficiency of 6.2 %, enhancing its sun protection factor (SPF) from 13.3 ± 1.4 (TiO 2 NPs) to 19.1 ± 0.7. In the contrast, the TiO 2 - g -HA 0.1 NPs exhibited a low photocatalytic activity to avoid the generation of hydroxyl radicals in a sunscreen formation. The TiO 2 - g -HA NPs under a state of aqueous slurries were then incorporated into a commercial sunscreen formulation. The TiO 2 - g -HA 0.1 Cream demonstrated exceptional stability, retaining >95 % of its initial SPF (24.5 ± 0.3) after 10 heating-cooling cycles, with no phase separation observed. In addition, the TiO 2 - g -HA 0.1 Cream sustained an enhanced moisturization performance (>80.0 % hydration retention under thermal and convective stress). Biocompatibility assessments on HaCaT keratinocytes revealed minimal cytotoxicity, with 88.5 ± 0.9 % cell viability for the TiO 2 - g -HA 0.1 Cream. Moreover, in vitro penetration profiles were possessed with the BALB/c mouse skin, confirming most nanoparticles retained on the epidermal surface for the TiO 2 - g -HA 0.1 Cream.

Commercial sunscreens suffer from low effectiveness, safety concerns, and feeling uncomfortable on the skin. In this work, by introducing UV filters, i.e., either Fe3+ doped Mg/Al layered double hydroxides (Mg/Al + Fe LDHs), an organic UV absorber, or both of them together, into waterborne cross-linkable polydimethylsiloxane (PDMS) coatings that consisted of vinyl-PDMS emulsion, hydrogen-PDMS emulsion, and Karstedt catalyst capsules, three types of skin sunscreens were facilely fabricated. The new sunscreens can be topically applied to the skin surface and form thick elastic films. The effect of the UV filter content on the UV-vis spectrum, UV-shielding performance, mechanical properties, water vapor transmittance, and adhesion strength of the films was thoroughly investigated. The cross-linked UV-shielding films had a non-greasy surface, moderate adhesion strength to skin, high transparency, a mechanical performance similar to human skin, and high water vapor transmission. All these features made the sunscreens comfortable to use. More importantly, even the sunscreens with a concentration of UV filters as low as 2.08 wt% organic UV absorber and 0.69 wt% Mg/Al + Fe LDHs exhibited the same UV protection performance as those commercial sunscreens with high sun protection factors. Such low UV filter concentrations are beneficial for alleviating safety issues. It is convincing that the cross-linkable PDMS-based sunscreens could be used as next-generation biomimetic sunscreens.
