Description

The present invention relates to a cleaning composition for textile products and a method for cleaning textile products.

With the spread of the new coronavirus infection (COVID-19), lifestyles have changed and wearing masks has become the norm. Due to the shortage of disposable non-woven masks, the habit of washing and reusing cloth masks has become widespread. Cosmetics such as lipstick and foundation tend to stick to masks. Oil-based cosmetics containing polymeric compounds such as wax and silicone, such as lipsticks and foundations, are extremely difficult to remove when they adhere to textiles, etc., and there is a consumer need to remove such cosmetic stains. is increasing.
Furthermore, if you apply foundation to the back of your neck so that it does not differ in color from your face, the foundation will stick to the collar of your shirt or blouse, etc. This stain tends to remain as foundation stain on clothing.
The easiest way to remove cosmetic stains from textile products such as clothing and cloth masks is to wash them using an automatic washing machine, but it may be difficult to remove the stains sufficiently. In addition, soaking clothes in order to improve the cleaning effect of cosmetic stains requires time and effort.

Patent Document 1 discloses a cleaning composition comprising about 1% to about 70% by weight of a surfactant and about 0.1% to about 10% of a predetermined non-alkoxylated ester amine and/or its salt. ing.
Patent Document 2 discloses that (A) terpene hydrocarbons are contained in an amount of 15 to 70% by mass, (B) a nonionic surfactant is contained in an amount of 20 to 85% by mass, and (C) water is contained in an amount of 0 to 20% by mass; A liquid cleaning composition that is transparent and uniform is disclosed.
