Octyl methoxycinnamate or ethylhexyl methoxycinnamate (INCI) or octinoxate (USAN), trade names Eusolex 2292 and Uvinul MC80, is an organic compound that is an ingredient in some sunscreens and lip balms.
Octyl methoxycinnamate is an ester formed from methoxycinnamic acid and 2-ethylhexanol.
Octyl methoxycinnamate is a liquid that is insoluble in water.

Octyl methoxycinnamate is primarily used in sunscreens and other cosmetics to absorb UV-B rays from the sun, protecting the skin from damage.
Octyl methoxycinnamate is also used to reduce the appearance of scars.

Uses
Octyl methoxycinnamate is the most common active ingredient in sunscreens for protection against UV-B rays.
Octyl methoxycinnamate may be combined with oxybenzone and titanium oxide.

Studies have evaluated the efficacy of octyl methoxycinnamate in preventing postoperative peritoneal adhesions and determined that octyl methoxycinnamate covering peritoneal surfaces decreases adhesion formation.
This effect is more notable when octyl methoxycinnamate is applied before the induction of trauma.

Chromophore groups, such as C=C, C=O, and O-N=O, have loosely held electrons that are excited by radiation.
Hence, octyl methoxycinnamate is able to absorb radiation when the electron energy level is increased to an excited state.

Spectral Information
The UV spectra of octyl methoxycinnamate contains a maximum at 310 nm.

Synthesis
Olefin metathesis has been widely studied.
One of the synthesis pathways for octyl methoxycinnamate includes cross metathesis.
The high efficiency of the nitro-Grela catalyst has been used in the cross metathesis of trans-anethole with 2-ethylhexyl acrylate to produce octyl methoxycinnamate.

Safety studies
One study performed in 2000 raised safety concerns about octyl methoxycinnamate by demonstrating toxicity to mouse cells at concentrations lower than typical levels in sunscreens.
However, another study concluded that octyl methoxycinnamate and other sun screening agents do not penetrate the outer skin in sufficient concentration to cause any significant toxicity to the underlying human keratinocytes.

Estrogenic and neurological effects were noted in laboratory animals at concentrations close to those experienced by sunscreen users and were also shown in vitro.
Octyl methoxycinnamate has been shown to be light sensitive with a decrease in UV absorption efficiency upon light exposure.
This degradation causes formation of the Z-octyl-p-methoxycinnamate from the E-octyl-p-methoxycinnamate.
In contrast, the OMC does not show degradation when kept in darkness for extended periods of time.

A study carried out in 2017 by the Research Centre for Toxic Compounds in the Environment at Masaryk University, Czech Republic, indicates that octyl methoxycinnamate (EHMC) may damage human cell DNA.
When exposed to sun rays, the spatial arrangement of its molecules changes and isomerisation takes place.
While until now only unchanged EHMC has been researched, Massaryk University researchers focused on its isomers and found out that it has a significant genotoxic effect under lab conditions.
Octyl methoxycinnamate means that it may potentially damage human DNA and cause genome mutations which may lead to serious health risks.

In swimming pools with hypochlorite in aqueous solution, octyl methoxycinnamate has been shown to produce chlorine-substituted intermediates.
The chlorination intermediates of octyl methoxycinnamate demonstrated weak mutagenic effects on the Salmonella typhimurium TA 100 strain.
The reactions depended on the pH, compound structures, and chlorine dose.

Octinoxate is a cinnamate ester and common ingredient in sunscreen and other skin care products to minimize DNA photodamage.
Octyl methoxycinnamate was originally developed in 1950's as an organic UV-B filter that absorbs UV-B rays from sun.
Octyl methoxycinnamate 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.
Octyl methoxycinnamate's use in pharmaceutical and cosmetic formulations is approved by FDA.

A clear, oil-soluble, "cosmetically-elegant" liquid that is the most commonly used chemical sunscreen.
Octyl methoxycinnamate absorbs UVB radiation (at wavelengths: 280-320 nm) with a peak protection at 310nm.

Octyl methoxycinnamate only protects against UVB and not UVA rays (the 320-400 nm range) – so always choose products that contain other sunscreens too.
Octyl methoxycinnamate is not very stable either, when exposed to sunlight, it kind of breaks down and loses its effectiveness (not instantly, but over time - it loses 10% of its SPF protection ability within 35 mins).
To make it more stable it can be - and should be - combined with other sunscreen agents to give stable and broad-spectrum protection (the new generation sunscreen agent, Tinosorb S is a particularly good one for that).

Regarding safety, there are also some concerns around Octinoxate.
In vitro (made in the lab not on real people) and animal studies have shown that it may produce hormonal (estrogen-like) effects.
Do not panic, the studies were not conducted under real life conditions on real human people, so it is probably over-cautious to avoid Octinoxate altogether.
However, if you are pregnant or a small child (under 2 yrs. old), choose a physical (zinc oxide/titanium dioxide) or new-generation Tinosorb based sunscreen, just to be on the super-safe side.

Overall, Ethylhexyl Methoxycinnamate is an old-school chemical sunscreen agent.
There are plenty of better options for sun protection today, but it is considered "safe as used" (and sunscreens are pretty well regulated) and it is available worldwide (can be used up to 10% in the EU and up to 7.5% in the US).

Octyl Methoxycinnamate is a UV-B category 1 sunscreen used for OTC sun protection products such as sunscreens, personal care products, sun care, baby sun care, daily skin care, decorative cosmetic with sun protection and broad spectrum UV- B filter.

Octyl methoxycinnamate, also called Octinoxate or (OMC), is a UV filter. Octyl methoxycinnamate can be absorbed rapidly through skin. Octyl methoxycinnamate has been detected in human urine, blood and breast milk, which indicates that humans are systemically exposed to this compound.
Octyl methoxycinnamate is an endocrine disruptor that mimics estrogen and can disrupt thyroid function.

Found in: Hair color products and shampoos, sunscreen, lipstick, nail polish, skin creams

What is Octyl methoxycinnamate
Octyl methoxycinnamate filters UV‐B rays from the sun.
Octyl methoxycinnamate does not protect against UV-A rays.
Octyl methoxycinnamate dissolves in oil, which makes it a fat-seeking substance in the body.
Octyl methoxycinnamate is formed by combining methoxycinnamic acid and 2-ethylhexanol- compounds which are not harmful on their own.

When mixed together, they form a clear liquid that does not dissolve in water.
Octyl methoxycinnamate is found in hair color products and shampoos, sunscreen, lipstick, nail polish, and skin creams.
In products other than sunscreens, it is used as a UV filter to protect the products from degrading when exposed to the sun.

health concerns: Endocrine disruption, reproductive and developmental toxicity, organ system toxicity

Endocrine disruption: Octinoxate increases cell proliferation in cells that grow in response to estrogen exposure.
Lifetime estrogen exposure is an established risk factor in the development and progression of breast cancer.
Octinoxate affects other hormone systems as well.
For instance, it reduces thyroid hormones in blood serum.

Thyroid hormones are critical for metabolic functions in the body including mammary gland development.
Octyl methoxycinnamate exposure has also been found to alter the reproductive systems of female offspring, with significantly lowered hormone (estradiol and progesterone) levels, which is associated with infertility and miscarriages.
In males there is a reduction of sperm count at all dose levels.

Reproductive organs and development toxicity: Numerous studies have reported that octinoxate exhibits antiandrogenic activity, which is linked to harmful effects on reproductive organ development in male and female fetuses exposed in utero.
These effects can be further passed onto their offspring.
Moreover, octinoxate alters weight and structure of reproductive organs in male and female rats.

Regulations: Octyl methoxycinnamate is approved for use in cosmetics worldwide; the maximum concentration in ready-for-use preparations varies according to local legislation.
According to the U.S. FDA the recommended use levels is up to 7.5 percent.

how to avoid: Despite the numerous studies and concerns about octinoxate toxicity and the effect on human body systems, octinoxate is approved worldwide [3]. In the United States, it is required to be listed on labels as an active ingredient. To avoid the product in sunscreen, read the list of active ingredients and skip products that rely on octinoxate. Check labels on hair care products, lipsticks nail polish and skin creams, and choose products that do not contain octinoxate or octyl methoxycinnamate (OMC).

Octyl Methoxycinnamate is an organic ester used in sunscreens (and lip balms) formed from methoxycinnamic acid and 2-ethylhexanol (Source).
Octyl methoxycinnamate is a sun blocking agent that absorbs UVB rays, but not UVA rays.
However, when it is exposed to sunlight, it is rendered less effective, although this reaction can be prevented by the addition of other ingredients (as seen in the formula of Tinsorb).
Octyl methoxycinnamate is also used to reduce to appearance of scars.

Safety Measures:
According to the Cosmetics Database, which rates Octyl Methoxycinnamate as 70% safe, there are many concerns regarding its use, including: biochemical changes that cause mutation and cell death upon exposure to sunlight (which is likely when used as a sunscreen ingredient); immunotoxicity and photoallergic effects; reproductive toxicity that leads to estrogenic effects; organ system toxicity, especially in the liver; and enhanced skin absorption. Octyl methoxycinnamate should be used with caution by pregnant women and children.

One study performed in 2000 raised safety concerns about Octyl Methoxycinnamate's toxicity, but was performed on mouse cells at concentrations lower than typical levels in sunscreens.
"However, a more recent study concluded that Octyl Methoxycinnamate does not penetrate the outer skin in sufficient concentration to cause any significant toxicity to the underlying human keratinocytes.
Estrogenic effects were noted in laboratory animals at concentrations close to those experienced by sunscreen users".

Octyl Methoxycinnamate at a Glance
Globally approved UV filter in use for over 50 years
Provides excellent UVB protection and filters a portion of UVA rays
Backed by numerous studies confirming its safety as used in sunscreens
Octyl methoxycinnamates cinnamic acid component can be allergenic for some
Also known as octyl methoxycinnamate and ethylhexyl methoxycinnamate

Octyl Methoxycinnamate is sunscreen agent used to protect skin primarily from the sun’s UVB rays.
Octyl Methoxycinnamate is one of several currently undergoing further safety testing under the purview of the United States Food and Drug Administration (FDA).
This testing is to gain a better understanding of the systemic absorption, metabolism, and elimination of these sunscreen actives when small amounts enter the body via topical use.

Octyl methoxycinnamate’s important to know that the presence of this or other sunscreen actives in the body does not mean your health is at risk.
Octyl methoxycinnamate is anticipated that the additional testing being done will reaffirm the safety of these ingredients; however, those who remain concerned can choose sunscreens with mineral actives (titanium dioxide and zinc oxide) which are not included in the FDA’s new call for additional testing.

Octyl Methoxycinnamate has a solid record of safety backed by decades of research and mounds of studies.
No studies have demonstrated that octinoxate, as used in SPF products, is harmful to people.
In the studies where such claims are made, the conditions are simply do not apply to how Octyl Methoxycinnamate is used in sunscreens.

This sunscreen ingredient’s cinnamic acid component can be allergenic for some people; however, this is an individual response and simply means your skin cannot tolerate this ingredient.
Octyl Methoxycinnamate is not considered irritating or photosensitizing to broad populations.

The risk of an allergic response can be minimized by formulating Octyl Methoxycinnamate in the oil phase (not the water phase) of a sunscreen.
This along with other formulary steps such as encapsulation and special emulsification approaches also stabilize Octyl Methoxycinnamate.
When such steps are not taken, upwards of 60% of Octyl Methoxycinnamate’s protective ability in a sunscreen is lost when exposed to UV light.
But since this issue is well known among sunscreen chemists, it’s not a concern for today’s sunscreens with oOctyl Methoxycinnamate.

Octyl Methoxycinnamate is sometimes accused of being a hormone disruptor.
This effect has primarily been demonstrated via oral intake of large amounts of this ingredient or examining its effect on isolated cells.
In cases where a hormonal change was measured via topical application, the difference was one million-fold less than what was measured from normal hormonal activity in the body.
Studies involving people have shown that Octyl Methoxycinnamate does not have a biologically significant effect on hormones.

There simply isn’t any research backing the claim that Octyl Methoxycinnamate has any link to health risks when used in sunscreen formulas.
In fact, the European Union’s (EU) permitted usage level for Octyl Methoxycinnamate in sunscreens is higher than the maximum amount permitted in the United States (7.5% in the United States, 10% in the EU).
China, Australia, Brazil, Argentina, India and Thailand are among the other countries permitting Octyl Methoxycinnamate levels up to 10%.

Octyl Methoxycinnamate is often accused of being a threat to coral reefs and has been banned from use in sunscreen in some parts of the world; however, numerous data gaps exist on this issue.
Such gaps include the lack of information on many other UV filters whose effects on coral reefs have yet to be studied.
More important, research is clear that several other factors, from changing climate to coastal development and invasive species have a much stronger link to coral reef damage and demise than sunscreen use by people.

This sunscreen active is one of several currently undergoing further safety testing under the purview of the United States Food and Drug Administration (FDA).
This testing is to gain a better understanding of the systemic absorption, metabolism, and elimination of these sunscreen actives when small amounts enter the body via topical use.

As referenced above, the presence of this or other sunscreen actives in the body does not mean your health is at risk.
Octyl methoxycinnamate is anticipated that the additional testing being done will reaffirm the safety of these ingredients; however, those who remain concerned can choose sunscreens with mineral actives (titanium dioxide and zinc oxide) which are not included in the FDA’s new call for additional testing.
