“…Wang et al also found that Zn-Ti LDH is a safe UV-shielding material as it has lower photocatalytic activity than TiO 2 and ZnO [ 15 ]. Ekambaram et al also gave same discussion and indicated its ability to shield UV radiation [ 25 ]. In the study of Naseem et al, Zn-Ti LDH as a UV-absorbing nanomaterial provided a method for protecting polypropylene from UV-vis degradation [ 26 ].…”

In this research, the effects of Zn-Ti layered double hydroxide (Zn-Ti LDH) as a UV-protection additive, which was added to the poly(butylene succinate-co-adipate) (PBSA) matrix, were investigated. Stearic acid was used to increase the hydrophobicity of Zn-Ti LDH via ion-exchange method. Transmission electron microscopy images of PBSA composites showed that modified Zn-Ti LDH (m-LDH) well-dispersed in the polymer matrix. Due to the effect of heterogeneous nucleation, the crystallization temperature of the composite increased to 52.9 °C, and the accompanying crystallinity increased to 31.0% with the addition of 1 wt% m-LDH. The additional m-LDH into PBSA copolymer matrix significantly enhanced the storage modulus, as compared to pure PBSA. Gel permeation chromatography and Fourier transform infrared spectroscopy analysis confirmed that the addition of m-LDH can reduce the photodegradation of PBSA.

“…Applications HTs/LDHs are widely studying in various field of science and technology owing to their versatility, easily availability, low-cost, simple synthetic methods, easy separation from the reaction mixture as well as their recycling potential according to the Green Chemistry point of view. The anion exchange capacity, basic nature due to the presence of Bronsted-Lewis acidic and basic sites, high surface area, increased basal spacing and memory effect or selfhealing property make them an effective catalyst and adsorbent material (95,(103)(104)(105)(106)(107)(108)(109). Due to their unique chemical structure and composition, as well as tunable interlayer galleries, HTs/LDHs can be used in a large number of applications, including delivery agents in bioactive and agrochemicals, adsorbents, catalysis, recycling of plastic material, flame retardants and packaging materials (110)(111)(112)(113)(114)(115)(116).…”

Hydrotalcite-like anionic clays (HTs) (also known as Layered Double Hydroxides (LDHs) are the most common group of ionic lamellar solids. These materials provide numerous advantages, such as economical and simple synthetic methods, easy separation from the reaction mixture, and recycling potential, according to the green chemistry point of view. X-ray diffraction (XRD) technique remains an essential tool in the characterization of many materials, including HTs/LDHs. XRD diffractogram of HTs/LDHs interpreted and revealed the hexagonal structure system of these materials with sharp and intense lines as characteristic peaks which shows their well-ordered crystalline nature. The various synthesizing aspects of these materials (nature and composition of divalent and trivalent metal cations, as well as anions, temperature, aging time, and pH) play important role in the crystallinity of prepared HTs/LDHs materials. This study highlighted and summarized the various research reports related to the effect of synthesizing aspects on crystallinity through XRD analysis of HTs/LDHs.

“…HT is an anion exchange material and its guest-host type structure offers exceptional intercalation chemistry for a wide range of applications (Kesavan Pillai et al 2020). In sunscreens, HT hybrids/LDH are used as carriers for controlled delivery of chemicals (UV absorbers/filters), which on direct contact with skin may cause skin allergies or irritation (Perioli et al 2006(Perioli et al , 2008Costantino et al 2008;Li et al 2017;Egambaram et al 2019). Due to its versatility, HT hybrids can also be used as a smart carrier delivery system for the transfer of natural pigments, which are essential for skin but suffer from disadvantages such as low stability, skin irritations, pH and temperature limitations, and light irradiations (Bernardos et al 2019).…”

The paper provides an overview of biocosmetics, which has tremendous potential for growth and is attracting huge business opportunities. It emphasizes the immediate need to replace conventional fossil-based ingredients in cosmetics with natural, safe, and effective ingredients. It assembles recent technologies viable in the production/extraction of the bioactive ingredient, product development, and formulation processes, its rapid and smooth delivery to the target site, and fosters bio-based cosmetic packaging. It further explores industries that can be a trailblazer in supplying raw material for extraction of biobased ingredients for cosmetics, creating biodegradable packaging, or weaving innovation in fashion clothing. Lastly, the paper discusses what it takes to become the first generation of a circular economy and supports the implementation of strict regulatory guidelines for any cosmetic sold globally.
