Abstract

The invention discloses hand cream which consists of the following components in parts by weight: 2-8 parts of lanolin, 10-18 parts of cyclodimethyl siloxane, 30-38 parts of water, 0.5-1.5 parts of citric acid, 2-9 parts of propylene glycol, 2-9 parts of cetanol and 0.2-1 part of a preservative. In the formula disclosed by the invention, the cetanol is taken as an emulsion-type substrate and is mixed with a greasing substrate, so that water absorption of the cetanol is enhanced; and two hands coated with the hand cream can be well protected from cracks even after being soaked in a mixing solution of a detergent, soap liquid and water for a long time.

Description

technical field [0001] The present invention relates to a hand cream, and more particularly, the present invention relates to a hand cream which protects hands for a long time when washing clothes. Background technique [0002] Working in front of the computer in an air-conditioned office building, due to the low humidity in the air-conditioned room and some radiation from the computer, the hands are relatively dry and need natural nutrients to moisturize, so you can choose a moisturizing hand cream. People who often work outdoors will damage their skin due to strong ultraviolet radiation, and wind and sand will also irritate their skin. Therefore, it is recommended to use protective hand cream to repair hands that have been severely "damaged" by wind and sun. The hands of people who often do housework will be exposed to alkaline substances such as detergent and soap, and the skin on their hands will be easily corroded and rough. You can often apply hand creams labeled with ...
