Bemotrizinol, or bis-ethylhexyloxyphenol methoxyphenyl triazine, is an organic UV filter found in over-the-counter sunscreen products. It primarily absorbs UV-A rays. Compared to older broad-spectrum chemical agents, bemotrizinol is more more fat soluble (oil soluble in cosmetic oils) to aid in efficacy and broad-spectrum activity . It is claimed to be photostable, which increases its onset of action and its efficiency in providing protection against UV-rays upon topical application . Bemotrizinol is commonly marketed as Tinosorb S and Escalol S.
Findings from an immature rat uterotrophic competitive binding assay suggest that bemotrizinol does not display significant binding affinities towards estrogen and androgen receptors in vitro, thus lacking intrinsic estrogenic, antiestrogenic, androgenic and antiandrogenic activity . Bemotrizinol minimizes erythema and provides excellent anti-aging effects as well as protectant effects on the skin's antioxidant defense system . In a comparative study of individuals with a history of polymorphic light eruption (PLE) undergoing photoprovocation, treatment of bemotrinizol was effective in preventing the development of PLE .
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.

Titanium dioxide, also known as titanium(IV) oxide or titania, is the naturally occurring oxide of titanium. It is used as a pigment under the names titanium white, Pigment White 6 (PW6), or CI 77891. It is typically extracted from ilmenite, rutile and anatase.

How Rivela Tint Sunscreen works
By absorbing UV-A and UVB rays ranging from 280 to 400nm, bemotrizinol serves to prevent the formation of free radicals induced by UV radiation .
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.
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.
Toxicity
Oral LD50 in rat is > 2000 mg/kg and dermal LD50 in rabbit is > 2000 mg/kg, respectively .
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.
Rat - LD50 Intratracheal (>100ug/kg ) Effects: Structural or functional changes in bronchi and trachea. There is inadequate evidence in humans for the carcinogenicity of titanium dioxide. Cancer in experimental animals: There is sufficient evidence in experimental animals for the carcinogenicity of titanium dioxide. Overall evaluation: Titanium dioxide is possibly carcinogenic to humans (Group 2B).
Volume of Distribution
No pharmacokinetic data available.
Ecamsule is only used topically, it not absorbed.
Six hours after titanium dioxide was administered to rats through IV injection at 250 mg/kg body weight, the highest concentration appeared in the liver; after 24 hours, the highest concentration was detected in the celiac lymph nodes, which filter the lymph from the liver.
Elimination Route
No pharmacokinetic data available.
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.
When male and female rats were fed a diet containing titanium dioxide (100 g/kg) for a period of about 32 days, a significant retention of titanium of 0.06 and 0.11 mg/kg wet weight was found only in the muscles; no retention was observed in the liver, spleen, kidney, bone, plasma, or erythrocytes
Half Life
No pharmacokinetic data available.
Ecamsule is only used topically, it does not have half life
The kinetics of TiO2 elimination in the rat lung following its deposition after 7 hr exposure at 10 and 50 mg/cu m were determined for periods up to 140 days...The retention half-time was 14 days for the first clearance phase and 88 days thereafter.
Clearance
No pharmacokinetic data available.
Ecamsule is used topically, it not absorbed or metabolized.
The clearance of titanium dioxide from the lungs was studied in rats after inhalation of 15 or 100 mg/cu m. The average median aerodynamic diameter of the titanium dioxide particles was 1.48 um. After a single exposure, about 40-45% of the deposited particles were cleared from the lung in 25 days. At 15 mg/cu m, 0.7% was found in the hilar lymph nodes indicating penetration of titanium dioxide particles from alveoli into the lymphatic system and partial clearance by the lymphatic route. The clearance rate was similar after intra-tracheal administration of titanium dioxide. At an exposure of 100 mg/cu m, the clearance rate decreased drastically. /Other researchers/ demonstrated the presence of titanium dioxide in the lymphatic systems of 3 workers employed in processing titanium dioxide pigments.
Elimination Route
No pharmacokinetic data available.
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 kinetics of TiO2 elimination in the rat lung following its deposition after 7 hr exposure at 10 and 50 mg/cu m were determined for periods up to 140 days.The retention half-time was 14 days for the first clearance phase and 88 days thereafter.
