What about baseball caps, UV-proof T-shirts or simply stay out of the sun, stay home?

No.
All sunscreens are synthetic (even Zinc oxide and Titanium dioxide). None should qualify for COSMOS certification.

What about naturally occurring molecules closely related to common UV filters?- Cinnamic acid derivatives such as ferulic, sinapic, or chlorogenic acid- Salicylic acid derivatives such as salicylate glucose ester- Anthranilates like methyl anthranilate (probably prohibited as drug precursor)- Flavonoids (there are MANY flavonoids in nature and most absorb UV)- Certain anthraquinones (though most are also very red)Though these plant constituents have one or more disadvantages such as a narrower UV spectrum, lower lipophilicity or even being hydrophilic, susceptibility to photobleaching, get assimilated (penetrate skin too easily too deeply), or are metabolically and chemically less stable…Neither do I know whetehr they are officially approved by whatever ECO-authority nor do I know their suitability for sunscreen formulations. These compounds aren’t just natural but they are quite frequently found at considerable concentration in nature because plants use them, under others, as sunscreens.THIS might be an interesting read.
