The skin of an adult person is, in most places, covered with a relatively thick (∼10 μm) barrier of keratinised dead cells. One of the main questions is still whether TiO2 NPs are able to penetrate into the deeper layers of the skin. The majority of studies suggest that TiO2 NPs, neither uncoated nor coated (SiO2, Al2O3 and SiO2/Al2O3) of different crystalline structures, penetrate normal animal or human skin. However, in most of these studies the exposures were short term (up to 48 h); only few long-term or repeated exposure studies have been published. Wu et al.83 have shown that dermal application of nano-TiO2 of different crystal structures and sizes (4–90 nm) to pig ears for 30 days did not result in penetration of NPs beyond deep epidermis. On the other hand, in the same study the authors reported dermal penetration of TiO2 NPs with subsequent appearance of lesions in multiple organs in hairless mice, that were dermal exposed to nano-TiO2 for 60 days. However, the relevance of this study for human exposure is not conclusive because hairless mice skin has abnormal hair follicles, and mice stratum corneum has higher lipid content than human stratum corneum, which may contribute to different penetration. Recently Sadrieh et al. performed a 4 week dermal exposure to three different TiO2 particles (uncoated submicron-sized, uncoated nano-sized and coated nano-sized) in 5 % sunscreen formulation with minipigs. They found elevated titanium levels in epidermis, dermis and in inguinal lymph nodes, but not in precapsular and submandibular lymph nodes and in liver. With the energy dispersive X-ray spectrometry and transmission electron microscopy (TEM) analysis the authors confirmed presence of few TiO2 particles in dermis and calculated that uncoated nano-sized TiO2 particles observed in dermis represented only 0.00008 % of the total applied amount of TiO2 particles. Based on the same assumptions used by the authors in their calculations it can be calculated that the total number of particles applied was 1.8 × 1013 /cm2 and of these 1.4 x107/cm2 penetrated. The surface area of skin in humans is around 1.8 m2  and for sun protection the cream is applied over whole body, which would mean that 4 week usage of such cream with 5 % TiO2 would result in penetration of totally 2.6 × 1010 particles. Although Sadrieh et al.concluded that there was no significant penetration of TiO2 NPs through intact normal epidermis, the results are not completely confirmative.

  • In conclusion, while preservatives play a role in food safety and shelf life, the prevalence of bad preservatives in our diet raises significant health concerns. Sodium nitrite, BHT and BHA, and sulfites are just a few examples of additives that pose health risks and may contribute to larger public health issues. By increasing awareness and making informed choices about what we consume, we can protect ourselves from the hidden dangers lurking in convenience foods.


  • However, the use of fertilizers is not without its challenges. Over-reliance on chemical fertilizers can lead to environmental issues such as soil degradation, water pollution, and loss of biodiversity. When fertilizers are applied excessively, nutrients can wash away into waterways, causing eutrophication—an increase in nutrient levels in water bodies that leads to excessive algae growth. This not only affects aquatic ecosystems but also compromises water quality for human consumption.


  • What are Taste Enhancers?


  • Glucono delta-lactone is a naturally occurring food additive derived from the oxidation of glucose. With a chemical structure that allows it to form a cyclic ester, E575 can interact with other compounds in food, making it versatile in its functionality. It is often recognized for its ability to act as a leavening agent, acidulant, and humectant, contributing to the texture and flavor of various food products.


  • Interestingly, the conversation around E621 mirrors broader trends in society concerning nutrition and health. As consumers become more health-conscious, additives like monosodium glutamate are often scrutinized alongside sugar, fats, and artificial colors. Consequently, it is essential for consumers to approach food labels with a critical eye, balancing enjoyment of flavors while being mindful of their overall dietary choices.


  • Regulatory bodies, such as the U.S. Food and Drug Administration (FDA) and the European Food Safety Authority (EFSA), rigorously evaluate the safety of aspartame. These organizations have deemed it safe for human consumption, making it a widely accepted sweetener in many countries. Manufacturers are required to adhere to strict guidelines and quality control standards to ensure that their products meet safety regulations. This contributes to consumer confidence in aspartame as a safe ingredient, which is essential for its continued use in the food industry.

  • In materials science, 2-butyne is utilized in the production of polymers and other materials. The reactivity of the triple bond provides opportunities for the creation of innovative materials with unique properties. For instance, it can be used to synthesize elastomers or specialized coatings that require specific mechanical or chemical characteristics.


  • In addition to its preservative properties, E304 is also valuable for its ability to improve the stability of certain vitamins in food products. It can help in preventing the degradation of fat-soluble vitamins, such as vitamins A, D, E, and K, thereby maintaining the nutritional profile of fortified foods. This characteristic renders E304 especially beneficial in dietary products that aim to deliver additional nutrients without compromising quality.


  • Aspartame is another widely used artificial sweetener, noted for its sugar-like taste and versatility. Approximately 200 times sweeter than sugar, aspartame is commonly found in diet sodas, sugar-free products, and as a tabletop sweetener. Aspartame is composed of two amino acids, aspartic acid, and phenylalanine. Notably, individuals with the rare genetic disorder phenylketonuria (PKU) must avoid aspartame, as their bodies cannot metabolize phenylalanine.
