Background of Development

In response to the global trend towards PFAS-free products due to environmental concerns, Goldwin has switched all of its brands to PFAS-free products. Based on the belief that "washing and maintenance" is important to maintain the performance of materials not only during the manufacturing stage but also during use, they have been working on developing new detergents

With the cooperation of a detergent manufacturer, and after approximately two years of repeated testing and improvements, this product was completed that can handle all kinds of dirt, from sebum stains to mud stains
