Please avoid fats/oils with high iodine value and poorly refined fats/oils to prevent oxidation and greasy/sticky products not to impair air permeability and collect dust...like this...http://books.google.com/books?id=SGOmAAAAIAAJ&lpg=PP1&pg=PA15#v=onepage&q&f=falseFluoropolymers are more powerful than silicones, but they are not as durable as silicones because those on leather are taken away by friction. Please make sure not to inhale...
I think so, too. Unopened silicone oils contain little or no impurity, but our hands would put impurities in it.Permeability coefficient is defined by Diffusion coefficient times Solubility coefficient (P=DS), which is derived from Fick's laws of diffusion. Permeability coefficient (or flux) can be measured by experiment.Here is "Oxygen Permeability through Silicone Liquid Membranes" (I am sorry, in Japanese). This paper says the lower molecular mass or viscosity silicone...
I guess nobody do an experiment on oxidation quantitatively over a few decades, so it would be difficult and arguable to answer about that.Generally speaking, a dictionary by JLIA (Japan leather and Leather goods Industries Association) says:Mr. Giles, Iron Heart UK, did a notable experiment on oxidation over 1.5 years and on a bending test. He used Mustang Paste (horse oil-based paste), Obenauf's Heavy Duty LP (plant oil-based paste), Obenauf's Leather Oil (plant...
If silicones and petroleum distillates are pure, they never oxidize, but they actually contain impurities. "Dark petrolatum" seems to contain plenty of impurities.http://digital.library.unt.edu/ark:/67531/metadc6294/m1/17/I don't know the time scale, but it might be on the order of 10 years, not 100 (10^2) years.There are three kinds of fatty acids: saturated fatty acids (SFA) which have no double bond (C=C), monounsaturated fatty acids (MUFA) which have one double bond,...
Sorry for my poor English and I should have written "a reasonable amount of Kiwi polish on the left shoe".The shoes for the experiment was polished by Mr. Matsumoto who was a shoeshiner at Hotel Okura Tokyo.
I haven't used glycerine saddle soap, but Lexol cleaner is not greasy. Does glycerine saddle soap contain too much glycerine? (For example, a pharmacist recommends 3% of glycerine and 4% of betaine for a homemade skin lotion.)
Belvoir Tack Conditioner Spray contains coconut oil and glycerin. They say "Glycerine - fills and seals any pores in the leather; forms a barrier against salt, dirt, grease and water".http://www.carrdaymartin.co.uk/product_details.html?cid=MQ==&pid=MTA=Glycerin is a moisturizing agent like lanolin and Lexol cleaner contains it not to dry up leather.
Yes and they say it means breathability and comfortableness.
Below would be one pea size dab.http://www.boq.jp/shoes/shoecare/05/index.htmThe following experiment was done by NHK (Japan's national public broadcasting organization). (Unfortunately youtube is a dead link. http://www.wretch.cc/blog/yisa/5817042)An excessive amount of Kiwi polish was applied on the right shoe (red label), a minimum amount of Kiwi polish on the left shoe (blue label).After 5 min jogging, both shoes were put into a plastic box and humidity inside each...
A dictionary for conservators says "cedarwood oil provides protection against mold growth and insect attack".http://cool.conservation-us.org/don/dt/dt2026.html
