The stability of enzymes in a powder detergent can be very significantly improved by the combination of four measures:
• Addition of reducing agent/peroxide decomposing catalyst/antioxidant to the core or the coating
• Addition of a multivalent cation to the core
• Addition of an acidic buffer to the core or to the coating
• Applying a salt coating onto the core.
通过四种措施的组合,可以大大提高粉末洗涤剂中酶的稳定性:
- 在核心或涂层中添加还原剂/过氧化物分解催化剂/
抗氧化剂
- 在核心中添加多价阳离子
- 在芯材或涂层中添加酸性缓冲剂
- 在芯材上涂一层盐。
