Sonnenmilch classic LSF 30

Nearly identical UV filter system (octocrylene, ethylhexyl salicylate, butyl methoxydibenzoylmethane, titanium dioxide nano) at what looks like the same SPF30 formulation base, plus matching texture agents like VP/hexadecene copolymer and dimethicone.

Matches on octocrylene, ethylhexyl salicylate, avobenzone and tocopherol, but adds homosalate and phenylbenzimidazole tetrasulfonate as extra filters not in the source, meaning a broader/stronger UV system rather than a true match.

Shares octocrylene, ethylhexyl salicylate, avobenzone and tocopherol, but adds homosalate, ethylhexyl triazone and terephthalylidene dicamphor sulfonic acid (mexoryl-type) for SPF50+, so it's a beefed-up filter system rather than a like-for-like match, and uses titanium dioxide non-nano plus aluminium hydroxide instead.

Shares octocrylene and avobenzone (butyl methoxydibenzoylmethane) but swaps ethylhexyl salicylate and titanium dioxide's synergist for bis-ethylhexyloxyphenol methoxyphenyl triazine, giving a different UV filter balance and it's SPF50 not SPF30.

Shares octocrylene, avobenzone and tocopherol but relies heavily on newer filters (ethylhexyl triazone, diethylhexyl butamido triazone, bis-ethylhexyloxyphenol methoxyphenyl triazine, phenylbenzimidazole sulfonic acid) absent from the source, making the actual UV-filter chemistry quite different despite overlap.
