Description

[Detailed description of the invention] Monoglycoside viscosity modifier for autopsy 1. Menko Rishu I FIELD OF THE INVENTION This invention relates to liquid detergent products.

2.11 Anti-Keiyu Emperor Nowadays, detergent manufacturers commonly change from producing powder or granular detergents to liquid detergents. The company is moving to manufacturing.

Liquid detergents typically contain large amounts of water in the product. Liquid detergent products are made from granular detergents It is much easier to manufacture than other products. Granular detergents require large amounts of capital in spray drying towers. Requires investment. Additionally, liquid detergent products can be in a more concentrated form. So consumer preference is towards liquid detergents. Most liquid detergent products are Inertness required to provide a free-flowing, non-clumping structure to mist-dried granular detergents Liquid detergent products do not contain any inorganic substances, so liquid detergent products can be used in significantly smaller quantities. However, it can still provide approximately the same level of active ingredients in the wash water.

A second consumer preference is directed towards products with the desired viscosity. dilute like water Water-thin products are undesirable; extremely watery products are When a consumer attempts to handle a 4-liter bottle that is typically filled with detergent, It is particularly easy to spill. Another benefit of liquid detergent products is that they clean clothes, especially stains. The main reason is that it can be used directly on the exposed parts. In such cases By increasing the viscosity of regular dilute liquid detergent products, you can apply the detergent to the soiled area for a longer period of time. It can be kept for a long time. There are also shampoos, liquid hand soaps on the market. soaps, body soaps, liquid dishwashing detergents, cosmetics, and relatively high viscosity personal detergents. Narucare (per-8onal care) products are on the market.

Various methods of increasing the viscosity of liquid detergent products are known in the art.
