To face the fetch cosmetics dropper bottle us is fastidious to fetch and decisive cosmetics dropper bottle us is fastidious


everybody talking recently jar packaging of cosmetics is apparent, just look nice, but to preserve the active ingredients of cosmetics is useless, what is truth? Let us start from what is a jar to understand it.
what is the jar?
refers primarily to the bottle mouth open so big, can be directly with his fingers into the harvest, see more at facial cream, mask, and the great basin of your home.
somebody say this: jar packing just figure 'good-looking', will make all the effective component failure
because the visual effect of jars appear more atmosphere, costly, so many brands use such packaging, to enhance the brand image, a bit more straightforward is to raise the price. And some of the effective ingredients especially antioxidant meets the air will be failure, expensive ingredient again also does not make sense. When using finger, large area in contact with the product will be damage to the product. It is best not to protect skin to taste with a finger to dig the bottle, in order to prevent bacterial infection to the unused part in the bottle, it is recommended to use digging stick or disposable cotton swab.
some people say that: jar packaging is clear, as long as the inside is cream
jar components may not volatilize, big jar with clearly has his way, so you not joking! Antioxidant content does not come into contact with air, light and heat. So antioxidants should be maintained in a cool place in airtight bottle. But, even the antioxidant, exposed to the air void, is only a surface is invalid, deep ingredient will still be valid. Cream texture is relatively thick, fat class composition, moisture volatilizes will come into contact with air. Grease-like composition block moisture volatilizes, so you can lock effective ingredient in the deep. Essence is easy to volatilize, because is not suitable for jar.
edit view: think of the most common daily jar would bring about a 'war', since the jar so vulnerable to pollution, then digging stick can't survive! We are not living in a sterile environment, actually with digging stick and dug by hand are all the same, the premise is to guarantee the purity of the harvest tool, and after each open bottle caps, to immediately put the caps with the quickest speed. Careful use of storage, need not negative in all the jars.
now what's the most expensive in the cosmetics? Essence is the most expensive! Although its small body, there are plenty gold! Look at the essence of high-end brands, all are packed in 'small dropper', it is beauty and wisdom of Miss World, or not in online?
'small dropper' advantage: take right amount, resistance to handle pollution
essence for aqueous extract, and are rich in nutrients, is very suitable for breeding bacteria. In order to avoid the external things, Including hand) Direct contact with the essence, the small dropper is important way to reduce pollution products. At the same time, the dosage can also be more precise, effective to avoid the waste.
'a little dropper disadvantage:' each time with a little bit left, can't get rid of waste name
usually dropper design of tube head was unable to reach the bottom of the bottle, and when the product use the last point, dropper will also part of the air inhaled, therefore cannot all exhausted, compared with the vacuum pump design is far to waste.
edit action: small dropper design principle is to use the pressure pump pumping, sucked up bottles of essence, use half couldn't find essence absorption method is very simple, first press the way will be clean, the air in the dropper if extrusion type dropper, is severely squeezing it back on the dropper bottle, don't let go the bottle tight; If the press type dropper, back on the bottle is also need to press the dropper completely, to ensure that the air was completely out. So next time, when using simply unscrew the bottle gently, do not need to squeeze, the essence is a use of enough.
had said in front of the bottle design, the following is the packing material, loading containers of maintain article material is multifarious, mainly three kinds of materials for plastics, glass and metal. Has it ever occurred to you, which one to use at most? Which one of the most suitable for the most stable?
the most widely used material - — Plastic, up to 80% using the
advantages: can change degree is high and forms, a variety of sizes, shapes, color, transparent and opaque can do it. Light weight, easy to transport, excellent printing, recyclable, etc.
disadvantages: no heat, light barrier property is not enough, poor solvent resistance ( Especially the fat class) 。 In addition, consider the stability of the content, some maintain article, does not fit in a plastic container. The most fragile material
- — Glass, USES the proportion of times, 8%
advantages: heat, light resistance, solvent resistance.
disadvantages: easily broken, is not easy to transport and carry them wherever you go.
edit guess: cosmetics packaging in the future may only use one kind of material, its light is easy to take, also can resist all kinds of pollution, the shelf life will be greatly extended, the heaviest if recycled recycling use, hope to see it in the near future!
