Embodiment 1

[0032] Coating performance test of the composition in Example 1. The control sample is Kelo-cote containing volatile cyclopentasiloxane, and the test site is the forearm of the participant. Through comparative tests, it is found that the composition in Example 1 can be easily applied, and there is no pain at the scar site when applied. Simultaneously, the test found that the thickness of the coating layer of the composition in Example 1 was greater than that of the gel layer of the Kelo-cote product.

[0033] The water vapor transmission rate test of the composition in Example 1 adopts the moisture permeable cup weighing method, and the testing instrument is PERME? Bomi? W3 / 060 water vapor transmission rate tester. The reference sample for the water vapor transmission rate test of the composition in Example 1 is a collagen film. The test method is to coat the silicone gel composition in Example 1 on the collagen film, measure its water vapor transmission rate, and then divide...

Abstract

The invention relates to a silicon gel combination, which comprises crosslinked polydimethylsiloxane and polydimethylsiloxane , and the silicon gel combination does not contain volatile annular siloxane. The silicon gel is prepared by compositing the crosslinked polydimethylsiloxane, polydimethylsiloxane and gas phase silica particles. According to the invention, good coating performance of the product can be reached by adjusting the proportion of crosslinked polydimethylsiloxane, polydimethylsiloxane and the gas phase silica particles, so that influence of long-term usage of the volatile annular siloxane on human health can be avoided.

Description

technical field [0001] The present invention relates to products for scar reduction and moisturizing of dry skin, and more particularly to a silicone gel composition. Background technique [0002] Scar is a general term for the appearance and histopathological changes of normal skin tissue caused by various traumas, and is generally divided into superficial scars, hypertrophic scars, atrophic scars, and keloids. The pathological difference between hypertrophic scar and normal scar lies in the thickening of collagen fibers in the deep part of the scar. Hypertrophic scars are manifested as protruding surfaces, irregular shapes, unevenness, flushing and hyperemia, and solid and tough texture. Keloids are the result of excessive proliferation of collagen fibers during the healing process of skin injuries. They appear as benign lumps that are higher than normal skin, have different shapes, and are red in color and hard. When the scar grows beyond a certain limit, various compli...
