In the 1980s, BP-3 was the most popular as a sunscreen formulation [ 1 ]. Uses [11] It is used, along with other benzophenones, in sunscreens, hair sprays, and cosmetics because they help prevent potential damage from sunlight exposure. EU Cosmetics Regulation Moreover, the antagonistic activity of BP-3 has been detected in yeast expressing human ER [67]. However, the prolonged (7-day) exposure to BP-3 reduced astrocyte and neuron viability by 25% and 36%, respectively.

It is a pale-yellow solid that is readily soluble in most organic solvents. Binder et al. [20] proposed that BP-3 undergoes an electron-driven internal conversion to its keto-tautomer, as the central mechanisms for its protective, antioxidative activity. However, the negative effects that may be induced by BP-3 on human health, cannot be clearly stated due to an insufficient number of performed studies. It possesses anti-aging properties. The modification concerns two substances, Benzophenone-3 and Octocrylene. No regulations have come of this study yet.

The global DNA hypomethylation and diminished activity of enzymes related to this process suggest the chromosomal instability and inappropriate gene expression pattern, leading to an increased risk of neurodevelopmental disorders or nerve degenerations. The resulting diradical will abstract a hydrogen atom from a suitable hydrogen donor to form a ketyl radical. 1. The directive, known as the empowering consumers for the green transition, received Read more. the contents by NLM or the National Institutes of Health. The draft Regulation aims to implement the Scientific Committees findings in the EU cosmetics regulatory framework. In animal experiments, BP-3 applied topically on the skin has been detected in the liver, heart, kidneys, spleen, muscle and testes [12].

For leave-on products: o Not to be used in sunscreen products and products marketed for exposure to natural or artificial UV light. Community members who have kept a low profile so far now want to make . [83] showed that this compound is capable of inhibiting an autophagy and disturbing the epigenetic state of primary neuronal cell cultures by the inhibition of global DNA methylation as well as reduction of the activity of histone deacetylases (HDACs) and histone acetyl transferases (HATs). [5] Without it, opaque or dark packaging would be required. According to Aker et al. The continuous and long-term exposure of the developing organism to a mix of chemicals contained in UV filters, which may act as endocrine disruptors or neurotoxins, could have consequences for its health in adult life.

On the other hand, manufacturers that place cosmetic products on the EU market in compliance with the previous requirements until January 28, 2023, have until July 28, 2023, to make those available on the EU market. Apart from the allergic reaction, benzophenone-1 metabolite of BP-3 can induce of photogenotoxicity and apoptosis via release of cytochrome c and Smac/DIABLO in human keratinocytes under UV radiation [36]. This interference with normal plant metabolism led to the inhibition of photosynthesis and respiration, restriction of carbohydrate synthesis and ATP regeneration, limiting the energy available for metabolic processes, and even leading to plants death [25]. Benzophenone is persistent, bioaccumulative and toxic (PBT). In the mouse neuronal cells culture, Wnuk et al. aluminium chloride) catalyst: since benzoyl chloride can itself be produced by the reaction of benzene with phosgene the first synthesis proceeded directly from those materials. The ban was to be effective as of January 1, 2021.
Benzophenone - Proposition 65 Warnings Website On the other hand, there is evidence that BP-3 can cross blood-tissue barriers, such as the blood-follicle barrier or the blood-placental barrier [59]. BP-3 also is used in plastic products to block and prevent UV rays from altering the plastic and the contents inside. Once applied, a small amount of BP-3 passes through the skin into the body. The regulatory definition. In the Fourth National Report on Human Exposure to Environmental Chemicals (Fourth Report), CDC scientists measured BP-3 in the urine of 2,517 participants aged six years and older who took part in the National Health and Nutrition Examination Survey (NHANES) during 20032004.

Simultaneous occurrence of urticarial and contact sensitivities. Benzophenone-3 or oxybenzone is an organic compound having the chemical formula C 14 H 12 O 3. Occasionally, wearing products containing BP-3 has resulted in a skin allergy or photo allergy, a skin reaction that occurs with exposure to sunlight. Large scale purification may be more economical using devices which utilize adsorbents such as the aforementioned alumina or molecular sieves. Furthermore, it is possible that BP-3 can be transmitted by carrier proteins in plasma, can act with human serum albumin and displace drugs and other substances, like sex and thyroid hormones, interfering the proper functioning of the human organism [11]. WTO. Oxybenzone belongs to the class of aromatic ketones known as benzophenones.
