The company was founded in 1977 and changed its name from the former company liyan industries ltd. To yugyu biotech, inc., effective 12 august 2014, as a result of its presence in the zhangdong agricultural biotech park. The products in operation range from personal skin cleaning and maintenance items, oils and aura to household cleaning agents, with more than 36 items and more than 18 exports, spread across taiwan's department stores and large supermarkets. The company has an autonomous core technology that works with or provides technical guidance and advice to the german drom spice company, one of the three manufacturers, and the world's high-quality soap-based manufacturer, ksp, permata. Most of the soap sold on the market is made using heat, which is more cost-effective and produces glycerine during the soap-making process, so that glycerine is generally extracted because it is much more expensive than soap. And the remaining soap, together with artificial chemical additives (e. G. Cleaning agents or synthetic active agents, etc.), is what we see in the market soap. But hand soap is the whole of glycerine! Because glycerine is a wetting agent, the use of hand soap is far more fertilizing than the marketed soap, for that reason, and market soap tends to be marketed because of cost considerations, the use of animal oils, such as pig oil, butter, or even kettle oil, is more expensive, although they are cheap and can easily be used in a way that can cause cavity congestion, is very detrimental to the skin, and hand soap is more suitable for use by you and your family, and the use of quality vegetable oil in material selection is much more expensive. The main ingredient in the porcelain lacquer soap is the precious silk protein extracted from 4,000 cocoon and extracted from dozens of plants, made of pure manual cryogenic cold. Using european imported raw materials, made throughout taiwan and certified by the international quality certification agency sgs, no hormones, heavy metals, preservatives are added and the use of animal grease is refused. It's true that it's a zero-adding self-made process, and it's used day and night, and it's dark, colored, beans, black head, and so on。
