Some other active ingredients in sunscreen, such as octyl-methoxycinnamate (OMC), a carbon-based ingredient, have also shown some potential toxicity in laboratory animal and cell culture studies, raising concerns about their risks.

In contrast, Environmental Working Group, while recognizing the critical data gaps, generally ranks sunscreens with nanoscale zinc and titanium oxides as having a lower hazard than those containing the most common active ingredients, such as oxybenzone and octyl methoxycinnamate.
DBP, DnOP (Di-n-octyl-phthalate) and DEP are contained in insect repellents — at times triggering dermal and inhalation exposures.
If you've ever wondered about the purpose of octyl methoxycinnamate (blocks UV-B) or xanthan gum (provides a nice texture), this give a brief overview.
Normal butyric acid or fermentation butyric acid is found in butter, as an hexyl ester in the oil of _Heracleum giganteum_ and as an octyl ester in parsnip (_Pastinaca sativa_); it has also been noticed in the fluids of the flesh and in perspiration.
The principal constituents of the oil are limonene and citral, together with small quantities of pinene, phellandrene, octyl and nonyl aldehydes, citronellal, geraniol, geranyl acetate, and the stearopten, citraptene.
Some common sunscreen ingredients that have been accused of being toxic are titanium dioxide, octyl methoxycimamate and oxybenzone.
: Synthetic fragrance, which can be highly irritating and are also a potential source of questionable sub-ingredients such as phthalates; formaldehyde-donor preservatives-such as diazolidinyl urea, DMD hydantoin, imidazolidinyl urea, and sodium hydroxymethylglycinate-which under certain circumstances of formulation and storage, these ingredients have the potential to release formaldehyde in very small amounts; and chemical sunscreens, such as oxybenzone and octyl methoxycinnamate, have safety concerns since many have been shown to have endocrine-disruption activity.
(Urtica dioica) oil, thyme¹ (thymus vulgaris) oil, octyl methoxycinnamate.
