Abstract
The present invention relates to processes and systems for treating leather articles, especially lipophilic fluid systems for treating leather articles.

Claims49
A process for treating a leather article comprising the step of contacting the leather article with a treating composition comprising a lipophilic fluid and a treating agent wherein the treating agent is insoluble in water such that the appearance of the leather article is not damaged compared to its original appearance prior to contacting with the treating composition.
A leather article treating composition comprising:
- a. from about 0.001% to about 5% of a treating agent;
- b. from about 0% to about 5% of water;
- c. from about 85% to about 99.999% of a lipophilic fluid;
- d. optionally, from about 0% to about 10% of a leather adjunct.
A consumable leather article treating composition comprising a level of treating agent such that when used in a lipophilic fluid treating composition, the treating agent is present at a level of from about 0.001% to about 5% by weight of the treating composition.
A leather article treating process wherein the leather article is treated in an apparatus that has been used previously to treat non-leather fabric articles by contacting the non-leather fabric articles with a non-leather fabric article treating agents that are capable of damaging the leather article, the process comprising the steps of:
- a. removing from and/or reducing the level present in the apparatus of the non-leather fabric article treating agents that are capable of damaging the leather article;
- b. placing the leather article into the apparatus;
- c. contacting the leather article with a treating composition comprising a lipophilic fluid and a treating agent wherein the treating agent is insoluble in water such that the appearance of the leather article is not damaged compared to its original appearance prior to contacting with the treating composition;
- and
- d. optionally, contacting the treated leather article from Step (c) with a replenishing composition;
- and
- e. optionally, drying the leather article;
- and
- f. optionally, removing the leather article from the apparatus.
A process for treating a leather article comprising the step of contacting the leather article with a treating composition comprising:
- a. from about 0.001% to about 1% by weight of the treating composition of a treating agent;
- and
- b. optionally, water;
- and
- c. optionally, a leather adjunct;
- and
- d. balance, a lipophilic fluid.
A process for treating a leather article comprising contacting the leather article with a lipophilic fluid such that the leather article is treated.
A consumable leather article treating composition comprising:
- a. from about 1% to about 100% of a treating agent;
- b. from about 0% to about 99% of water;
- c. from about 0% to about 99% of a lipophilic fluid;
- d. optionally, from about 0% to about 99% of a leather adjunct.
