ARIOL M is particularly suitable in the decreasing operations In the bating phase and after the chrome tannage. Infect it is used As decreasing agent in the initial phase of re-tanning and as Dispersing in the following dyeing phase.

ARIOL M is a surfactant of universal use, because it has good Wetting, dispersing and emulsifying properties.

Use
It is used From 0.7% to 1.2% in bating.

• Ecological Degreasing Auxiliary

Chemical Composition
Derived from ethoxylate alcohol

Characteristics Appearance : achromic liquid Active substance : about 30% pH in 10% sol : 5,5-6 ionic charge : nonionic compatibility : anionic and nonionic biodegradability : sup- To 90% COD : mg/g 600

FREE OF ETHOXY NONYL PHENOL

Properties
ARIPOL ML carries out a decreasing, emulsifying and deterging Action on the natural fats of the skins and it can be used on all Articles. Then, as opposed to the decreases based on ethoxy nonyl phenol, ARIPOL ML is much more biodegradable and has lower COD Values

Use
It is used from 0,4% to 0,8% according to the articles.

• Super conc. Degeasing product on solvent base

Chemical Composition
Combination of ethoxylate alcohol with solvent

Characteristics Appearance : achromic liquid Active substance : about 30% pH in 10% sol : 5,5-6 ionic charge : nonionic compatibility : anionic and nonionic

Properties
ARIPOL M300 is free of ethoxylate Nonyl phenol but is has in its place special efhoxylate alcohol in Order to get the maximum between fhe decreasing action of the Solvent and the deterging action of the surfactant.

Therefore an exceptional cleaning of the grain, with the use of ARIPOL M300 is obtained.

Use
You can use it only between 1% and 2% or in mixture with ihe Surfactant between 0,5% and 1%

• DEGREASING AGENTS

Characteristics Appearance : Colourless to pale yellow, clear viscous liquid Chemical character : Crypto-anionic based on modified poly-Glycol ether pH in 10% sol : 7 + 0.5 solid content : 33 + 1 % Dilutability : Readily dilutable with water Stability to solutions of - Acid : Good in weak acid - Salt : Good - Hard Water : Good

Technical Information
ARIOL ABI Liquid is an effective degreasing agent for hides and skins And can be used in pelt, E.I. tanned and wet blue stages.

ARIOL ABI is specially suitable for degreasing sheep skins which is capable of dispersing chrome soaps and so can be used to degrease Wet blue skins to achieve level dyeing for aniline leathers It also Helps to minimize back bone patches in suede dyeings.

ARILIX is a useful leather processing auxiliary products for the production of chrome uppers, Gloving leathers, leathers clothing, ARILIX A promotes the even distribution of chromes and fats through the cross section if the leather. It disperes the natural fats and enchances the softness of the leather. Use of ARLIX A helps to promote level dying and avoids drown grain when used in semi chrome tanned leather.

CHEMICAL COMPOSITION
Derivation of fatty acid, amphoteric in nature.

Characteristics Appearance : Brown colour liquid Properties : pH of 10% Solution : About 7 {approximately} Compatibility : Compatible with Anion active, : Non Ionic and cation active : substance Stability : Very good stability in Acids : Alkalies and Salts Storage : Good stability

Application

• Picking :
  ARILIX A is suitable in pickle or in chrome tanning of leather. It promotes an even distribution of the chrome and dispersion of the Chrome and fine dispersion of natural fats. The picking process can be accelerated by adding 0.5 to 1.5% ARILIX A [on pelt weight)
• Fatliquoring Process : 0.1 to 1% ARILIX A {on shaves weight) is added together with the retain agent or liquor in preliminary Fat liquoring process. It's use in main fatliquoring process, improves penatration and uniform distribution of the fat liquor 1 -5% ARILIX A (on weight of fat liuor).
• Leveling of Dyes : 0.3 to 0.5%

MULTI PURPOSE FAT Liquid
Amarlix AU Paste is used in the preliminary fat-liquoring of chrome tanned leather usually in combination with AMARLIX GSNN PASTE. It acts as a dispersing agent for natural fats and chrome tan Uniform distribution of chrome in upper and central layer of leather means level shades in dyeing. AMARLIX AU PASTE promotes excellent and even fat liquoring through the cross section hereby giving leather a relatively dry handle and leaves suede leathers good buffing properties and regular nap. Its use in preliminary fat liquors prevents thin and large -sized leather from entanglement and increase the tensile strength and stitch resistance of leather.

CHEMICAL COMPOSITION
Weakly cation active emulsion of natural oil.

Characteristics Appearance : Cream coloured, pourable paste. pH of 10% Solution : Approx. 5

Storage

• Good at 40C a more consistent Surface layer may be formed which can again be dispersed homogenously by stirring

 

Emulsification
Emulsion can be formed by adding five times the amount of water at 50C & be further dilutedas per requirements

Compatibility

• Very Good with Non-ionic and Cation active.
• Compatible with weakly anion active substance.

 

LIGHT FASTNESS : Good

STABILITY

Acid	Good
Alkalies	Not Stable
Salts	Fairly Good

 

Application

• For Suede Leather (as main fat-)
  It gives good softness and good level shades when used after drum-dyeing the leather.
• For Pre-fatliquoring
  It used before neutralising , AMARLIX AU PASTE gives deeper penetration. Normally 2-4 % AMARLIX AU PASTE is used for treatment.
• As surface fat (Final fatliquorig) for grain leather. Addition of AMARLIX AU PASTE to the nearly exhausted fat-liquoring bath, gives following advantages.
  - Better exhaustion of .
  - Better Fixation of the anionic fat in the leather.
  - It reduces the absorbancy of the grain .
• In chrome tanning : Use of AMARUX AU PASTE avoids chafe Marks and minimises inter twining of sheep and goat skins.

 

Concentration
Appro . 0.2% on weight of pelt . 5) For special effects in fashion articles : AMARLIX AU PASTE (1-2% if used in exhausted anionic fat bath gives greasy handle leather.
