Product Overview
Leather Fatliquor 5.0 by Leather Doctor is an emulsion of fat and oil softener for all leather, suede, hide, and skin against dryness, stiffness, and cracking.
This pH 5.0 emulsion ionic negative (-ve) charged fatliquor replenishes the original diminishing fat and oil and rejuvenates with softness and strength.
The fat plumps the leather with fullness and the oil relaxes coarse breaks, creases, and wrinkles to impart drapes and suppleness, prolong premature aging, and prevent cracking.
Fatliquor 5.0 Plus is the leather scent version.

. . .
1: What is Fatliquor?
1.1: Fatliquor 5.0 conditioner is a micro-emulsion of fat, oil, and water for rejuvenating, restoring, and softening all types of leather and suede to impart their original suppleness and protect them from dry rotting and stiffness.
1.2: Concentrate when mixed with 1: 5 parts of distilled water turns into a milky micro-emulsion that looks like fresh milk ready to use.
1.3: Stiff or dried leather and suede are hydrated and relaxed with Hydrator 3.3 to pre-shrunk dimension for a proven effective fatliquoring system.
2: How does Fatliquor work?
2.1: Fatliquor 5.0 typically works after hydration with Hydrator 3.3 to open up the fibrous leather structure, ensuring thorough and even absorption of fat and oil.
2.2: The fat plumps the leather with fullness and the oil lubricates each fibril like millions of interconnecting hinges to glide over one another smoothly once the water content evaporated.
2.3: Effective fatliquoring result in softer leather with increase tensile and tear strength.
3: Why Does Fatliquor Work?
3.1: The fat content in Fatliquor 5.0 plumps up the leather, preventing it from easily collapsing into creases and wrinkles during stress or flex.
3.2: The oil content lubricates the fibers, allowing them to slide over one another smoothly like millions of interconnecting hinges.
3.3: Fatliquor 5.0 helps to keep leather at its optimum physical performance and prevent premature aging.
3.4: Fatliquor 5.0 softens the leather when dry, providing stretchability, compressibility, and flexibility while significantly increasing its rip tensile strength.
4: When Does Fatliquor Work?
4.1: When Fatliquor 5.0 is applied, the water-encased molecule breaks free when an ionic attraction occurs between the fat and oil with the leather fiber.
4.2: The excess free water content is wicked out, leaving breathing space for the natural transpiration of the leather.
5: What is the Purpose of using Fatliquor?
5.1: Fatliquor 5.0 carries an ionic negative (-ve) charge to hydrogen bond with the ionic positive (+ve) charge of the leather fibers, thus freeing up pores for better breathability.
5.2: Unlike other stuffing conditioning oils that just fill up the breathing pores.
6: What is the Purpose of Fatliquor?
6.1: Fatliquor 5.0 conditioning is for replenishing the original fat and oil that diminishes through sun bleaching, aging, heat, and alkaline over-exposure or cleaning.
7: What is the original percentage of leather fatliquor content from the tannery?
7.1: Fatliquor content retained after a universal tannery when dries varies by an average of 14% depending on the leather type and its usage.
8: How does the Fatliquor content of Fat and Oil Diminish?
8.1: Fatliquor percentage drops as the fat and oil content diminishes through aging and heat, or when it is leached out by water or chemical overexposure during cleaning.
9: How to determine the Percentage of Fatliquor required by the leather?
9.1: The Fatliquor content required by the leather is based on the weight of the leather to the percentage of remaining fat-liquor.
10: How to Calculate the Percentage of Fatliquor required?
10.1: Fatliquor requirement is simply calculated by the weight difference in percentage.
10.2: If the weight of the leather is 100gm and the leather moisture reading is less than 1%.
10.3: Applying 80gm of Fatliquor 5.0 will deliver a result incremental of 13.3% fatliquor when dry as the 66.6% water content evaporates.
11: Why is Hydrator 3.3 used before Fatliquor 5.0?
11.1: Hydrator 3.3 is used both as a hydrator to relax, open up the inter-fibrillary spaces, and facilitate and redistribute colloidal water movement.
11.2: Besides, protonating it is use to post-clean fatliquor surface remnants.
12: What is the ratio of usage between Hydrator 3.3 and Fatliquor 5.0?
12.1: Hydrator 3.3 to Fatliquor 5.0 ratio practice is 2 to 1, and it works out to be approximately 160gm of Hydrator 3.3 plus 80gm of Fatliquor 5.0 to replenish 100gm dry leather, from less than 1% back to the original tannery up from an average of 14% fatliquor content.
12.2: Fatliquor 5.0 by weight content is comprised of 16.66% ionic negative (-ve) charged fat and oil, encased in 83.33% of water.
12.3: Fatliquor water content that encased the fat and oil molecule in an emulsion suspension when hydrogen bonds with the ionic positive (+ve) leather protein fiber break free and discharge clear from the leather structure to the surface.
13: How to Use Fatliquor 5.0?
13.1: Concentrate in the bottle is to be cut/mixed well with 5 parts warm distilled water before use.
13.2: Apply and redistribute with appropriate brushes or pads until the thickness of the leather or suede is saturated.
13.3: Repeat each time water contents evaporate leaving behind only the fat and oil content.
13.4: Sticky residue is further driven into the leather structure or rinsed off until surface milky fat and oil turn clear with Hydrator 3.3.
13.5: Allow natural drying for extra softness.
13.6: Suppleness of leathers is further staked/massaged/flexed accordingly with a little wet back with Hydrator 3.3 until dry.
14: Tips:
14.1: Always pre-condition the leather/nubuck/suede with Hydrator 3.3 to relax, and open up the fiber structure before Fatliquor 5.0.
14.2: A fully fatliquor replenished leather maintains an average of 14% fat and oil content, while vegetable-tanned leather is more thirsty.
14.3: Insufficient fat-liquoring (fat and oil) content may remain stiff and may also suffer cracking from staking, massaging, or flexing.
14.4: When crispy dry, prior surface contamination/damages may darken as soiling particulates resurface.
14.5: Removes surface soiling particulates with Eraser 4 for all leathers including nubuck and Eraser 5 for suede.
14.6: Stretching the dark areas lightly will also lighten the appearance.

15.1: The Lazarus Effect https://leatherdoctor.com/sheepskin-care-kit-sr3/#product-reviews
This product revived my 40-year-old Sheepskin coat that cracked at the touch of it after applying another company's 'Restoration' product. That other product ruined my coat, and I was about to throw it away but took a chance on the Leather Doctor. After applying Hydrator 3.3, I saw an immediate change. I then continued with the Fatliquor 5.0 and was shocked to see the change. My coat is now as soft and supple as it was when I purchased it in 1975! Don't even take a chance on valuable leathers with other companies products, this one will amaze you with its results.
