example 1
[0042] Example 1 refreshing patch
[0043] Add 32.5% BR9000 polybutadiene, 40% PIB6H polyisobutylene, 22% HS100000YP2 hydroxyethyl cellulose, 5% borneol, and 0.5% limonene into the mixer, mix for 2 hours, exhaust and Mix for another 1 hour, then remove it.
[0044] The mixture was weighed and placed between two silicone release papers, and then pressed into a sheet with a thickness of 0.05 ± 0.01 mm using a plate vulcanometer. Subsequently, the release paper is peeled off from the sheet, and the sheet is then combined with the transparent film. The sheet is cut into certain shapes as desired.

Abstract
The present invention provides a hydrocolloid composition which, based on 100% by weight of the hydrocolloid composition, comprises: 10-90%) by weight of a polyisobutylene tackifier; 5-55% by weight of a hydrophilic absorbing substance; and 0.1-20% by weight of a functional ingredient. The invention further provides an article containing the hydrocolloid composition.
Description
technical field [0001] The present invention relates to a hydrocolloid composition and articles comprising the same, in particular, to a functional hydrocolloid composition for personal care or medical treatment and articles comprising the same. Background technique [0002] Products containing natural plant ingredients are widely used in personal care or medical treatment and exhibit various effects, for example, refreshing, mosquito repelling, anti-acne, anti-itch, etc. Typical products are cooling oil, cooling cream, perfume, etc. In addition to these traditional products, there are also some natural plant products of adhesive paste type or hydrogel type on the market. However, all the above mentioned products have their corresponding disadvantages. [0003] -Liquid type or ointment type products [0004] Typically, they are applied by hand to the corresponding part on the skin, for example products for refreshing the mind may be applied to the temples and the like. ...
