Mechanism of seed initiation by PEG

Peg is a kind of high molecular material, which can not penetrate into living cells. Peg initiation is osmotic regulation, which means that the seeds are in the medium of low water potential, partially hydrated but without visible germination. This treatment can promote the germination of seeds, improve the emergence rate and uniformity of seeds, especially for the germination of seeds that are not easy to germinate. At the same time, it can improve the ability of drought resistance and cold resistance of seeds.

In short, the mechanism of seed initiation by PEG is that the germination ability of the seed has been improved obviously because of the completion of some material metabolism process which is conducive to germination and growth in a certain osmotic pressure solution. However, the metabolism itself is a very complex physiological and biochemical process.

The chemical substance that can produce obvious pearlescent effect is called pearlescent agent. Its main components are glycol stearate and glycol stearate.

Glycol stearic acid dissolves or emulsifies after being heated in the surfactant complex, and lens like crystals will be separated out during the cooling process, thus producing pearlescent luster. In the use of liquid washing products, it can produce obvious pearlescent effect, increase the viscosity of the product, moisturize the skin, nourish the hair and protect the hair, and have the anti-static effect. It has good solubility with other surfactants, and can reflect its stable pearlescent effect and thickening conditioning function. No irritation to skin, no damage to hair.

Peg has wide compatibility with various volumes, wide viscosity range and hygroscopicity. Polyethylene glycol PEG has good lubricity, thermal stability and low toxicity, which makes users like it widely.

The hygroscopicity of PEG with low molecular weight is similar to that of glycol. Peg is very soluble in water. Peg is soluble in many organic solvents such as ethanol, acetaldehyde, alkanolamide, ammoniate, amine, chlorinated hydrocarbon, aromatic hydrocarbon, ester, glycol ester, glycol ether ester, ketone, organic acid, anhydride and phenol.

In the production of cosmetics, pearlescent pigments from the outer packaging to the content, can give full play to its role in color. Powder, lipstick, eye shadow, nail polish and aerosol spray can be added to the base material in a ratio of 3%. The luster is very attractive. Pearlescent pigment can also be combined with ethylene glycol stearate and other organic pearlescent agents to make the color and luster better.
