Aspects : Yellow clear liquid Basis : Anionic surfactants with bio degradable bactericides free From PCP Charge : Anionic ph : In 10% aqueous solution, Stability : Stable with acids, alkalis and salts in usual Concentrations Solubility : Freely soluble in hot or cold water PROPERTIES ORGOL SK is suitable for optimums soaking of dried material (sheep, goat, hide, fur) dry salted (buffalo, African cow) and fresh salted skins. ORGOL SK controls the growth of bacteria, avoiding putrefaction of hides and skins and hair slip. ORGOL SK accelerates the soaking process by its good wetting, soil dissolving and fat emulsifying properties. APPLICATIONS The application of ORGOL SK is not restricted to a certain ph value. Thus ORGILIME AW or soda ash may be applied as a sharpening agent to the soaking bath. Practically ORGOL SK is applied in the pre-soaking and in the main soaking. Pre-soaking : (ratio 1:10) gr/lit ORGOL SK or % ORGOL SK on dry weight

4 Soaking of fur skins and wild animal skins: (ratio 1:10) 1.5 gr/lit ORGOL SK or 1.5 % ORGOL SK on dry weight Soaking of dried sheep and goat skins: (ratio 1:10) gr/lit ORGOL SK or % ORGOL SK on dry weight Soaking of dried hides: (ratio 1:10) gr/lit ORGOL SK or % ORGOL SK on dry weight Soaking of fresh salted skins: (ratio 1:5) gr/lit ORGOL SK or % ORGOL SK on fresh salted weight SHELF LIFE If ORGOL SK is stored between 15 C and 40 C, the product has a shelf life of one year. Special care should be taken to close the drums after use.

Aspects : Yellow - green liquid ph : In 10% aqueous solution, Stability : Excellent in alkali and salts Vegetable tanning Solubility : Disperses easily in water Biodegradability : Biodegradable PROPERTIES ORGCIDE B-5 can be used for curing of raw material to control the growth of halophilic bacteria and any other types of bacteria as well. In soaking, ORGCIDE B-5 is compatible with all enzymes soaking system and also conventional system and allows any suitable soaking duration. In liming, ORGCIDE B-5 avoids the scuff grain due to bacterial damage. ORGCIDE B-5 can also be used for the preservation of finishing products based on casein. APPLICATIONS Soaking of fresh salted hides and skins: % ORGCIDE B-5 on fresh salted weight or 0.05 to 0.1 gram per litre of water (ratio 1:2) Soaking of dry hides and skins: % ORGCIDE B-5 on dry weight or 0.3 to 0.6 gram per litre of water (ratio 1:6)

10 ORGOL SD ORGOL SD is a scouring and degreasing agent for liming and bating Aspect : Light yellowish liquid Basis : Combination of highly efficient wetting agents, emulsifiers and dispersing agents ph : In 10% aqueous solution Charge : Anionic Solubility : Good in cold and warm water PROPERTIES ORGOL SD increases the penetration of the liming chemicals into the hides and skins and therefore enhancing the liming process. ORGOL SD improves the dissolving, emulsifying and removing of natural fats and greases. During liming process, ORGOL SD increases the grain scouring and the removal of hair roots. During bating process, ORGOL SD helps the degreasing of grain side and the removal of destroyed hair roots. When ORGOL SD is used during beam house process, the levelness of the dyeing is improved (aniline, Nubuck). ORGOL SD is low foaming. APPLICATIONS ORGOL SD can be added undiluted in the liming float.

11 ORGOL SD is added together with the liming chemicals. When using ORGOL SD during bating process, we recommend that it is added together with the bating agent after pre-deliming. ORGOL SD is effective from ph 5.5 to It is not recommended to use ORGOL SD at ph values below 5.0. Examples: During liming During bating : 0.2 to 0.6% ORGOL SD : 0.5 to 1.2% ORGOL SD for garment and gloving leathers and 0.3 to 0.8% ORGOL SD for upper leathers SHELF LIFE If ORGOL SD is stored between 5 and 40 C, the product has a shelf life of one year. Special care should be taken to close the drums after use.

Free from pentachlorophenate PROPERTIES ORGCIDE VSP has been formulated to allow long term preservation of tanned hides and skins at competitive cost. The high efficiency of well known TCMTB has been combined with other fungicides to get a maximum spectrum activity against main fungus species found in wet blue such as Aspergillus Niger, Trichoderma viride and Penicilium. Due to its formulation with various biocides, ORGCIDE VSP is therefore very consistent and efficient even if the targeted mould becomes resistant to one biocide. ORGCIDE VSP could be used safely during all the year. The efficiency of the preservation could be again enhanced by combining ORGCIDE VSP with ORGCIDE SP. ORGCIDE VSP will be uniformly fixed in all parts of the leather. APPLICATIONS ORGCIDE VSP can be diluted if necessary, prior to application with 10 times its own weight of water.

41 ORGTAN XO Poly functional aldehyde syntan, for white leather Aspect : Transparent liquid Basis : Mixture of Oxazolidine ph : In 10% aqueous solution, Active matter : 50 ± 1% Solubility : Readily soluble in hot water Light Fastness : Excellent Note : Colour may turn to yellow brown on ageing. However This will not affect the performance of the product. PROPERTIES ORGTAN XO is a high efficient self tanning agent with reactive sequestering groups with very high light fastness and high fixing capacity. It does not cause yellowing. The main advantage of ORGTAN XO is it does not crosslink on its own, during storage which is the case with conventional aldehyde tanning agents. ORGTAN XO can be used in pre-tanning. ORGTAN XO can be used in tanning. During chrome tanning, when used as a pre-tanning material, a fuller and smoother wet blue is resulted. When ORGTAN XO is applied during vegetable tanning, the absorption of the vegetable tanning material is faster and hence the grain surface is very smooth, unlike the normal EI tanned leathers. When ORGTAN XO is applied after chrome tanning, before fixation, the exhaustion is excellent and results in round and smooth grained wet blues. As it is generally difficult to get fullness and roundness in imported hides, it is particularly suitable for imported hides. ORGTAN XO when used in retanning the medium and heavy imported wet blue hides it imparts

42 good fullness, grain smoothness and softness. ORGTAN XO disperses fat and improves fullness and firmness. ORGTAN XO can be used in re-tanning ORGTAN XO can be used for both chrome tanned and vegetable tanned leather. ORGTAN XO is very suitable for making chrome free and white leathers. It increases the shrinkage temperature and non yellowing. Additional advantages of using ORGTAN XO are considerable improvement of tear strength, increase in the depth of dyeing, fur tanning where the optic and sheen of the fur is not reduced. APPLICATIONS Pre-tanning (For both chrome tanning and Vegetable tanning) : % ORGTAN XO, based on pelt weight Chrome tanning / Chrome free tanning : % ORGTAN XO, based on pelt weight Retanning for White leathers Retanning for Regular process : % ORGTAN XO, based on shaved weight : % ORGTAN XO, based on shaved weight SHELF LIFE ORGTAN XO has a shelf life of one year if it is stored in its original sealed package.
