The only biodegradable lube here, and it is wax-based on purpose
Muc-Off Bio Dry chain lube, 120 ml
A wax-based dry chain lubricant in 120 ml, fully biodegradable and made from renewable sources.
What you are getting
Muc-Off Bio Dry chain lube, 4.06 fl oz (120 ml). A wax-based dry lube, fully biodegradable, “made completely from renewable sources”, with Extreme Pressure Additives. $14.
It is the only lubricant in this group with an environmental claim
“Fully biodegradable chain lubricant that is just as friendly on the environment as it is on your ride”, and in the description: “derived from natural ingredients and made completely from renewable sources”.
Chain lube ends up on the road. It drips, it gets wiped onto rags, and the excess washes off in rain. A biodegradable formula from renewable feedstock is a real difference from a mineral-oil base, and none of the other five lubricants on this page claims either.
Muc-Off publishes no standard behind “fully biodegradable” — no OECD test number, no percentage in how many days — so it is a claim rather than a certification.
Wax-based, which is the division on this shelf
“Our Bio Dry Chain Lube uses a wax-based formula to protect against contaminants in dry and dusty conditions.”
Set that against the WD-40 Wet on this page: “the no-wax formula will not build up inside chain links”. Wax is the feature here and the fault there, and both are correct — this shelf’s tag is that one sentence: wet lube survives rain, dry lube keeps dust off the chain.
A wax film is dry to the touch, so grit bounces off instead of sticking. In sustained rain it flakes and the chain runs dry.
“Extreme Pressure Additives”, which is a class and not a compound
“The integral ‘Extreme Pressure Additives’ in our bike chain oil coat every part of the link.”
EP additives are a genuine category in lubricant chemistry — compounds that react with metal under load to form a sacrificial film where the oil film would be squeezed out. What Muc-Off does not say is which. The Finish Line Dry on this page names boron nitride; this names the function.
Twelve dollars less than the published Muc-Off on this shelf’s other listing
This site already publishes the Muc-Off All-Weather lube in 120 ml. Same brand, same bottle size, different job: all-weather is the compromise, this is the dry specialist.
If the bike only rides in summer, the specialist beats the compromise. If it rides year round and only one bottle is being bought, the all-weather one is the honest choice — and the three lubricants already published on this shelf are all all-weather.
11.7 cents a milliliter
$14 for 120 ml. The Finish Line Dry on this page is 7.1 cents, for 237 ml of a dry lube with a named ceramic. That is the comparison this bottle has to answer, and its answers are the wax base and the biodegradability.
What is not published
No reapplication interval, no biodegradation standard or percentage, no EP additive named, no temperature range, and no viscosity. Five bullets, of which the fifth is “suitable for all bikes”.
