Wet wipes are generally made of a nonwoven fabric. Non-woven fabric is a fabric that does not need to be spun woven fabric. It is made by directly bonding the fibers together by physical means (mechanical, thermal bonding) or chemical methods. The raw materials can be various. A variety of spunlace nonwovens are the most commonly used ones, which have a soft surface and a good hand feel.
The characteristic of the wet wipe is that it has a liquid inside, and the content of the liquid in the wet wipe generally accounts for about 80%. The main ingredients are water and additives. In order to avoid the reaction between water and liquid medicine, the water used in the wet tissue must be specially treated water, such as purified water, pure water, and the like.
There are many types of additives. The most common one is the humectant, propylene glycol, which helps the effective substances in the solution dissolve in water, making the water less volatile.
In order to maintain the activity of various substances in the wet tissue, preservatives such as phenoxyethanol, methylparaben, etc., and quality wet wipes are added, and the amount of preservative added is within the scope of the state.
In order to achieve the cleaning effect of removing dirt and grease, a surfactant such as polyoxyethylene hydrogenated castor oil, polyether or the like is added to the wet tissue.
In addition, in order to achieve a specific effect, special additives such as chrysanthemum oil are added for soothing and anti-inflammatory effects.
While these additives bring certain benefits, they also cause some problems when used. For example, exposure to excessive chemical agents such as preservatives and alcohol may cause skin irritation such as contact dermatitis. Long-term exposure to synthetic surfactants can damage the sebum membrane that protects the skin and dry the skin. Excessive scent will make people feel uncomfortable. The ingredients contained in some disinfectant wet wipes are also harmful to the human body. For example, chlorine and bleaching powder, it is not suitable for long-term, high-frequency use of wet wipes.
TIP: When buying wet wipes, be sure to pay attention to the date of production and use. It is best not to use wet wipes that have expired or have been produced for a long time.
