Abstract
The present invention generally relates to a biodegradable lubricating wipe, such as wet wipes. The wet wipes typically being fibrous sheet materials, pre-moistened with a solution for improved lubrication and/or protection of an area. In one embodiment the solution is comprised of a bio-based lubricant, a bio-based solvent and water. In one embodiment, the solution is comprised of mineral spirits and refined soybean oil. In another embodiment the solution is comprised of soy methyl ester and refined soybean oil. In yet another embodiment, the fibrous sheet material of the invention is biodegradable and the solution portion breaks down into a vaporizing component and a biodegradable carrier portion.
Claims25
A wet wipe comprising:
- a fibrous sheet material;
- and
- a solution comprising a first portion and a second portion,
- wherein the first portion is a solvent derived from agricultural crops and selected from soy methyl ester, ethyl lactate, or a suitable combination thereof, and the second portion is a vegetable oil, fruit oil, animal fat, algae oil, halophyte oil, or fungi oil lubricant, wherein the fibrous sheet material is at least about 50 percent by weight biodegradable or compostable, and wherein the solution comprises from about 5 percent by volume to about 90 percent by volume of the lubricant, and from about 95 percent by volume to about 10 percent by volume of the solvent.
A wet wipe comprising:
- a fibrous sheet material;
- and
- a solution comprising a first portion and a second portion,
- wherein the first portion is a solvent derived from agricultural crops and selected from soy methyl ester, ethyl lactate, or a suitable combination thereof, and the second portion is a vegetable oil, fruit oil, animal fat, algae oil, halophyte oil, or fungi oil lubricant, wherein the fibrous sheet material is at least about 50 percent by weight biodegradable or compostable, and wherein the first portion is present in an amount of at least about 20% by volume and the second portion is present in an amount of at least 2.5% by volume.
A wet wipe comprising:
- a fibrous sheet material that is at least about 50 percent by weight biodegradable or compostable;
- and
- a solution comprising about 40% to about 50% soybean oil, about 50% to about 60% of soy methyl ester, and a preservative.
A wet wipe comprising:
- a fibrous sheet material;
- and
- a solution comprising a first portion and a second portion,
- wherein the first portion is a solvent derived from agricultural crops comprising soy methyl ester, ethyl lactate, or a suitable combination thereof and is present in an amount of at least about 10%, and the second portion is a vegetable oil, fruit oil, animal fat, algae oil, halophyte oil, or fungi oil lubricant and is present in at least about 2.5% by volume, and wherein the fibrous sheet material is at least about 50 percent by weight biodegradable or compostable.
A wet wipe comprising:
- a fibrous sheet material;
- and
- a solution comprising a first portion and a second portion,
- wherein the first portion is a solvent derived from agricultural crops comprising soy methyl ester, ethyl lactate, or a suitable combination thereof, and is present in at least about 20% by volume, and the second portion is a vegetable oil, fruit oil, animal fat, algae oil, halophyte oil, or fungi oil lubricant, and wherein the fibrous sheet material is at least about 50 percent by weight biodegradable or compostable.
A wet wipe comprising:
- a fibrous sheet material that is biodegradable and/or compostable;
- and
- a solution comprising:
- from about 2.5 percent by volume to about 90 percent by volume of at least one vegetable oil, fruit oil, animal fat, algae oil, halophyte oil, or fungi oil lubricant;
- and
- from about 97.5 percent by volume to about 10 percent by volume of at least one solvent derived from agricultural crops, the solvent comprising soy methyl ester, ethyl lactate, or a suitable combination thereof.
A wet wipe comprising:
- a fibrous sheet material that is biodegradable and/or compostable;
- and
- a solution comprising:
- from about 0.1 percent by volume to about 80 percent by volume of at least one vegetable oil, fruit oil, animal fat, algae oil, halophyte oil, or fungi oil lubricant;
- and
- from about 99.9 percent by volume to about 20 percent by volume of at least one solvent derived from agricultural crops, the solvent comprising soy methyl ester, ethyl lactate, or a suitable combination thereof.
