Cosmetics packaging materials compatibility test common problems

Cosmetics packaging materials compatibility test is a listed before an important part of, can't be omitted, the compatibility between material of cosmetics packaging materials can be divided into the following three: chemical compatibility, the physical compatibility, biological compatibility, in many cases the incompatibility of incompatibility is not for a single phenomenon.

a, chemical incompatibility

chemical decomposition of cosmetics packaging materials, and react with cosmetic ingredients, performance for cosmetics packaging materials or content change in appearance or smell.

2, biological incompatible

when do cosmetics packaging material components ( Such as plastic additives, residual organic solvents, volatile organic compounds, harmful heavy metals, etc. ) Migration to the contents, and the damage to the character of the cosmetics, characterized by biological incompatible. Such as plastic cracking during high temperature on the monomer, the plastic products in general, such as plasticizer, stabilizer, and paint, if these additives dissolution will become incentives to make the contents spoiled or smell. Ink pigment, dyestuff, pigment, the poisonous and harmful chemicals can through the plastic film to migrate to the inner packaging of cosmetics, causing harm, in addition to the environment pollution can be absorbed by packaging materials, and then migrated to the content. Metal materials in heavy metal migration to cosmetics.

glass alkali dissolution may occur frequently in store of cosmetics, and cause the contents change color separation, precipitation, and the change of PH, additional glass packaging material has a defect, is sensitive to low temperature, and the temperature difference is larger, both the cosmetics in the south to the north is likely to happen frost crack phenomenon. Glass bottle monopoly high-end skincare market before, now has been gradually using performance better acrylic, but the high cost of acrylic let its application scope is limited.

3, physical incompatible

when cosmetics packaging material and the material influence each other, some such as penetration, cracking, the phenomenon such as adsorption or dissolved. Because cosmetics packaging materials with general solvent resistance, in addition, cosmetics, generally milder, so cosmetics packaging materials and incompatible more characterized by physical incompatible, but in many cases the incompatibility of incompatibility is not for a single phenomenon.
