OCTINOXATE
Octinoxate is an ester formed from methoxycinnamic acid and 2-ethylhexanol, known for its role as a UV-B blocker in sunscreens and cosmetic products.
Despite its effectiveness as a UV-B filter, Octinoxate is not stable under sunlight and can lose up to 10% of its SPF protection within 35 minutes, necessitating the use of stabilizing agents.
As a clear, oil-soluble liquid, Octinoxate enhances the formulation of water-resistant products and acts as a photo stabilizer, protecting the integrity of other ingredients.

Octinoxate is an old-school chemical sunscreen agent.
Octinoxate is an ester formed from methoxycinnamic acid and 2-ethylhexanol.
Octinoxate is a liquid that is insoluble in water.
However, Octinoxate is known to undergo a series of photodegradation processes that decrease its effectiveness as a UVB filter.
In particular, the trans (E) form—which is considered so far as the most stable isomer—converts to the cis (Z) form under the effect of light.
In this work, by using post-Hartree–Fock approaches [CCSD, CCSD(t), and CCSD + T(CCSD)] on ground state Octinoxate geometries optimized at the MP2 level, we show that the cis and trans forms of the gas-phase Octinoxate molecule have comparable stability.
Test calculations on the same structures with a series of dispersion-corrected density functional theory-based approaches including the B2PLYP double hybrid predict the trans structures to be energetically favored, missing the subtle stabilization of cis-Octinoxate.
Octinoxate is a clear, oil-soluble, "cosmetically-elegant" liquid that is the most commonly used chemical sunscreen.
Octinoxate absorbs UVB radiation (at wavelengths: 280-320 nm) with a peak protection at 310nm.
Octinoxate only protects against UVB and not UVA rays (the 320-400 nm range) – so always choose products that contain other sunscreens too.
Octinoxate 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 Octinoxate 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).
Overall, Octinoxate is an old-school chemical sunscreen agent.

This sunscreen active, Octinoxate, 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.
It’s important to know that the presence of Octinoxate or other sunscreen actives in the body does not mean your health is at risk.
It 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.
