Avobenzone is dibenzoyl methane derivative. It is oil soluble ingredient. Avobenzone has the ability to absorb ultraviolet light over wider range of wavelengths. It is included in many commercially available sunscreens which are used as wide spectrum sunscreens. Avobenzone is very sensitive to light, to increase its stability and duration of action, photostablizers are added in the sunscreen product. Avobenzone has an absorption maximum of 357 nm. Sunscreens containing avobenzone is indicated for providing protection from the sun. In addition to limiting the skin's exposure to the sun, using sunscreen agents may help reduce long-term sun damage such as premature aging of the skin and skin cancer.
Octinoxate is a cinnamate ester and common ingredient in sunscreen and other skin care products to minimize DNA photodamage. It was originally developed in 1950's as an organic UV-B filter that absorbs UV-B rays from sun. It is often combined with nanoparticles or other water-resistant liposomes in formulations to increase the localization at the epidermis and decrease the risk of percutaneous absorption. Its use in pharmaceutical and cosmetic formulations is approved by FDA.
Acts as a photoprotective agent that protects the skin by preventing and minimizing the damaging effects of ultraviolet (UV) rays of natural light. The cellular effects of UV irradiation include DNA damage, cell cycle arrest, immunological depression, apoptosis, and transcriptional changes .
Octocrylene is a compound often used as an additive in sun screen, and is thought to have skin moisturizing effects because of its emollient properties. What makes this chemical such a popular additive to sun block, is its ability to neutralize UV radiation dissipated by sunlight, and to minimize skin damage from prolonged sun exposure. Octocrylene is also often combined with avobenzone, another common sunscreen ingredient often appearing on ingredient labels. Because of its effectiveness, the chemical has been approved across the globe for use in cosmetics and skin care products, but the concentrations of this ingredient are usually limited to no more than 10 or 12 percent. However, the use of this chemical doesn’t just stop with sunscreen for face and arms, but can extend to a variety of other products, like hair spray, tannin oil, BB cream, conditioner, and CC cream, among others. Octocrylene may cause contact and photocontact allergy.
Oxybenzone is an organic compound used in sunscreens. It is a derivative of benzophenone. It forms colorless crystals that are readily soluble in most organic solvents. It is used as an ingredient in sunscreen and other cosmetics because it absorbs UV-A ultraviolet rays.
Oxybenzone is an organic compound used in sunscreens. It is a derivative of benzophenone.
A metallic element of atomic number 30 and atomic weight 65.38. It is a necessary trace element in the diet, forming an essential part of many enzymes, and playing an important role in protein synthesis and in cell division. Zinc deficiency is associated with anemia, short stature, hypogonadism, impaired wound healing, and geophagia. It is identified by the symbol Zn .
A newer study suggests implies that an imbalance of zinc is associated with the neuronal damage associated with traumatic brain injury, stroke, and seizures .
Understanding the mechanisms that control brain zinc homeostasis is, therefore, imperative to the development of preventive and treatment regimens for these and other neurological disorders .

How Nextgen Sun Screen works
It blocks UVA I, UVA II, and UVB wavelengths, thereby limiting the impact of UV rays on skin. Diminish the penetration of ultraviolet (UV) light through the epidermis by absorbing UV radiation within a specific wavelength range. The amount and wavelength of UV radiation absorbed are affected by the molecular structure of the sunscreen agent.
Absorbs UV-B (predominantly) and UV-A rays while accumulating in the outermost layer of the epidermis. Like any other photoprotective agents, octinoxate prevents the damage to cells and deoxyribonucleic acid (DNA) by reducing the p53 protein expression following UV exposure and also increases the skin's tolerability to UV rays .
Octocrylene is an effective oil soluble liquid UV‐B filter. It has excellent dissolving properties for crystalline UV filters. Due to its outstanding photostability it is used as photostabilizer. Conjugated acrylate portion absorbs UVB and short-wave UVA (ultraviolet) rays with wavelengths in the range of 280-320 nm which protects the skin from direct DNA damage. The ethylhexanol portion is a fatty alcohol, which functions as an emollient due to it's hydrophobicity.
Oxybenzone absorbs UV-A ultraviolet rays, preventing them from reaching the skin.
Zinc has three primary biological roles: catalytic, structural, and regulatory. The catalytic and structural role of zinc is well established, and there are various noteworthy reviews on these functions. For example, zinc is a structural constituent in numerous proteins, inclusive of growth factors, cytokines, receptors, enzymes, and transcription factors for different cellular signaling pathways. It is implicated in numerous cellular processes as a cofactor for approximately 3000 human proteins including enzymes, nuclear factors, and hormones .
Zinc promotes resistance to epithelial apoptosis through cell protection (cytoprotection) against reactive oxygen species and bacterial toxins, likely through the antioxidant activity of the cysteine-rich metallothioneins .
In HL-60 cells (promyelocytic leukemia cell line), zinc enhances the up-regulation of A20 mRNA, which, via TRAF pathway, decreases NF-kappaB activation, leading to decreased gene expression and generation of tumor necrosis factor-alpha (TNF-alpha), IL-1beta, and IL-8 .
There are several mechanisms of action of zinc on acute diarrhea. Various mechanisms are specific to the gastrointestinal system: zinc restores mucosal barrier integrity and enterocyte brush-border enzyme activity, it promotes the production of antibodies and circulating lymphocytes against intestinal pathogens, and has a direct effect on ion channels, acting as a potassium channel blocker of adenosine 3-5-cyclic monophosphate-mediated chlorine secretion. Cochrane researchers examined the evidence available up to 30 September 2016 .
Zinc deficiency in humans decreases the activity of serum thymulin (a hormone of the thymus), which is necessary for the maturation of T-helper cells. T-helper 1 (Th(1)) cytokines are decreased but T-helper 2 (Th(2)) cytokines are not affected by zinc deficiency in humans [A342417].
The change of Th(1) to Th(2) function leads to cell-mediated immune dysfunction. Because IL-2 production (Th(1) cytokine) is decreased, this causes decreased activity of natural-killer-cell (NK cell) and T cytolytic cells, normally involved in killing viruses, bacteria, and malignant cells [A3424].
In humans, zinc deficiency may lead to the generation of new CD4+ T cells, produced in the thymus. In cell culture studies (HUT-78, a Th(0) human malignant lymphoblastoid cell line), as a result of zinc deficiency, nuclear factor-kappaB (NF-kappaB) activation, phosphorylation of IkappaB, and binding of NF-kappaB to DNA are decreased and this results in decreased Th(1) cytokine production .
In another study, zinc supplementation in human subjects suppressed the gene expression and production of pro-inflammatory cytokines and decreased oxidative stress markers [A3424]. In HL-60 cells (a human pro-myelocytic leukemia cell line), zinc deficiency increased the levels of TNF-alpha, IL-1beta, and IL-8 cytokines and mRNA. In such cells, zinc was found to induce A20, a zinc finger protein that inhibited NF-kappaB activation by the tumor necrosis factor receptor-associated factor pathway. This process decreased gene expression of pro-inflammatory cytokines and oxidative stress markers .
The exact mechanism of zinc in acne treatment is poorly understood. However, zinc is considered to act directly on microbial inflammatory equilibrium and facilitate antibiotic absorption when used in combination with other agents. Topical zinc alone as well as in combination with other agents may be efficacious because of its anti-inflammatory activity and ability to reduce P. acnes bacteria by the inhibition of P. acnes lipases and free fatty acid levels .
Toxicity
A minimum toxic dose has not been established. Significant toxicity is not expected
Slightly hazardous in case of skin contact, eye contact, ingestion and inhalation. Octinoxate may form reactive singlet oxygen species and induce anti-estrogenic effects . UV-induced molecular breakdown of octinoxate may interfere with cellular processes or induce oxidative damage in human skin . The NOAEL (no observed adverse effect level) is 450 mg/kg bw/day for fertility and reproductive performance, for systemic parental and developmental toxicity in Wistar rats .
Octocrylene is one of those ingredients that can be absorbed into the skin and some studies have shown that it may promote generation of potentially harmful free radicals when exposed to light. Since free radicals can damage DNA, there is concern that this ingredient might have contributed to an increased incidence of melanoma in sunscreen-users compared to non-users.
According to the Toxnet database of the U.S. National Library of Medicine, the oral LD50 for zinc is close to 3 g/kg body weight, more than 10-fold higher than cadmium and 50-fold higher than mercury .
The LD50 values of several zinc compounds (ranging from 186 to 623 mg zinc/kg/day) have been measured in rats and mice .
Volume of Distribution
Ecamsule is only used topically, it not absorbed.
A pharmacokinetic study was done in rats to determine the distribution and other metabolic indexes of zinc in two particle sizes. It was found that zinc particles were mainly distributed to organs including the liver, lung, and kidney within 72 hours without any significant difference being found according to particle size or rat gender .
Elimination Route
Can be systemically absorbed after skin application, being found in the deeper layers of the stratum corneum as well as urine, plasma, and breast milk . The mean maximum plasma concentration detected after application of 2mg/cm2 sunscreen was 7ng/mL in women and 16ng/mL in men .
Ecamsule is used topically, it not absorbed or metabolized.
Zinc is absorbed in the small intestine by a carrier-mediated mechanism . Under regular physiologic conditions, transport processes of uptake do not saturate. The exact amount of zinc absorbed is difficult to determine because zinc is secreted into the gut. Zinc administered in aqueous solutions to fasting subjects is absorbed quite efficiently (at a rate of 60-70%), however, absorption from solid diets is less efficient and varies greatly, dependent on zinc content and diet composition .
Generally, 33% is considered to be the average zinc absorption in humans . More recent studies have determined different absorption rates for various populations based on their type of diet and phytate to zinc molar ratio. Zinc absorption is concentration dependent and increases linearly with dietary zinc up to a maximum rate [L20902].
Additionally zinc status may influence zinc absorption. Zinc-deprived humans absorb this element with increased efficiency, whereas humans on a high-zinc diet show a reduced efficiency of absorption .
Half Life
Ecamsule is only used topically, it does not have half life
The half-life of zinc in humans is approximately 280 days .
Clearance
Ecamsule is used topically, it not absorbed or metabolized.
In one study of healthy patients, the clearance of zinc was found to be 0.63 ± 0.39 μg/min .
Elimination Route
Can be detected in urine in unchanged form .
Ecamsule is used topically, it not absorbed.
In vivo studies show oxybenzone is abosorbed transdermally (through the skin) and is excreted in the urine.
The excretion of zinc through gastrointestinal tract accounts for approximately one-half of all zinc eliminated from the body .
Considerable amounts of zinc are secreted through both biliary and intestinal secretions, however most is reabsorbed. This is an important process in the regulation of zinc balance. Other routes of zinc excretion include both urine and surface losses (sloughed skin, hair, sweat) .
Zinc has been shown to induce intestinal metallothionein, which combines zinc and copper in the intestine and prevents their serosal surface transfer. Intestinal cells are sloughed with approximately a 6-day turnover, and the metallothionein-bound copper and zinc are lost in the stool and are thus not absorbed .
Measurements in humans of endogenous intestinal zinc have primarily been made as fecal excretion; this suggests that the amounts excreted are responsive to zinc intake, absorbed zinc and physiologic need .
In one study, elimination kinetics in rats showed that a small amount of ZnO nanoparticles was excreted via the urine, however, most of the nanoparticles were excreted via the feces .
