Cosmetics packaging, jars and dropper bottles

It's been said recently that cosmetics in jars are all about appearance and beauty, but do nothing to preserve their active ingredients. What's the truth?

Let's start with what a jar is.

What is a jar?

It is to point to bottle mouth to open especially big, can go in with the finger directly dig take, see more at face cream, facial mask and the big washbasin of your home.

Some people say that the packaging of a wide-mouth bottle is just "good-looking", which will make all the active ingredients ineffective. Because the visual effect of a wide-mouth bottle is more grand and luxurious, many brands adopt such packaging to improve the brand image and, more bluntly, to raise the price.

And some of the active ingredients, especially antioxidants, lose their potency when exposed to air, so expensive ingredients don't make sense.

When the fingers are in use, large areas of contact with the product will also cause pollution.

It is best not to use your fingers to dig into the skin care products in the bottle, in order to avoid bacterial infection to the unused part of the bottle, it is recommended to use a digging stick or disposable cotton swab.

However, some people say that the package of wide-mouth bottle is actually ok, as long as the ingredients of the jar containing face cream may not volatilize, the big brands obviously have their reasons for using wide-mouth bottle, so expensive is not a joke!

Antioxidants do not have access to air, light and heat.

So antioxidants should be kept in a cool place in an airtight bottle.

But even antioxidants that don't work when they come into contact with air are only effective on the surface, and the deeper components still work.

The texture of face cream is relatively thick, have the composition of grease kind, have moisture to volatilize just can come into contact with air.

Oils and fats block the evaporation of water and thus keep the active ingredients deep inside.

The essence is easy to evaporate, so it is not suitable for wide-mouth bottles.

Editor's view: It's hard to imagine a war of words happening with the most common jar, but if jars are so susceptible to contamination, digging sticks isn't an option either.

We do not live in a sterile environment. In fact, digging with a digging stick is the same as digging by hand. The premise is to ensure the cleanliness of the digging tools.

Use and store carefully, so you don't have to deny all jars.

What is the most expensive cosmetic nowadays?

Essence is the most expensive!

Despite its small body, it contains a lot of gold!

Take a look at the essence of those high-end brands, all of them are packaged with "small dropper". Is it a Miss World with both beauty and intelligence, or a showgirl with nothing to show?

Disadvantages of "small dropper" : A little bit left every time, can not get rid of the name of waste usually the dropper design can not reach the bottom of the bottle, and when the product used to the last point, the dropper will absorb part of the air at the same time, so it is impossible to use up, compared to the vacuum pressure pump design far more waste.

The design principle of the small dropper is to use a pressure pump to extract the essence from the bottle. When using half of the product, it is found that the essence cannot be absorbed. The method is very simple.

If it's a pressure dropper, press the dropper down completely when you put it back in the bottle to make sure the air is completely squeezed out.

So the next time you use it, just gently unscrew the bottle, don't need to squeeze, the essence is enough to use once.

Having said the design of the bottle, the next thing I want to talk about is the material of the packaging. The materials of the containers for the maintenance products are various, mainly plastic, glass and metal.

Have you ever wondered which one you use most?

Which one is best for stability?

Advantages of "small dropper" : get the correct dosage, resist pollution essence is mostly aqueous essence, and contains rich nutrients, which is very suitable for bacterial reproduction.

In order to avoid direct contact with external materials (including hands), small dropper is an important way to reduce the contamination of products.

At the same time, the dosage can be more accurate, effectively avoid waste.

Rotten street material -- plastic, use scale up to 80% advantage: changeable degree is tall, all sorts of size specification, shape, color, transparent, opaque can do.

Light weight, easy to transport, good printing, recyclable, etc.

Disadvantages: heat resistance, light barrier, poor solvent resistance (especially oil).

So the first bottleneck of plastic containers is that they can't be sterilized with hot steam, washed with water, or photosterilized.

Additional, consider the stability of content, some maintain article item, do not suit to pack in plastic container.

The most stable and reassuring material, glass, adopts the next proportion, with 8% advantages: heat, light and solvent resistance, the absolute winner.

The darker the color, the more beneficial to the preservation of anti-oxidation, anti-aging, whitening effect of maintenance products, because these ingredients are very active, very easy to be affected by light.

So, unless it is glass of inferior quality, maintain tasted the home that suits to live most is vitreous container.

Disadvantages: in addition to easy to break, declined as a child's toys, there are few drawbacks, of course, if you know that it is made of glass, it will never be placed in the position of easy to be knocked off.

Editor's guess: in the future, cosmetics packaging may only use one material, it is light and easy to take, but also can resist all kinds of pollution, shelf life will be greatly extended, most importantly, can be recycled and reused, I hope to see it in the near future!
