Lipstick is the cosmetic product that any woman has. It allows you to give an attractive look to your lips, as well as care for them. In order for the product to retain its color and properties, it should not only be carefully selected, but also changed to new products in a timely manner. About the shelf life of lipstick is described in the article.
Is there a deadline?
Like other cosmetics, lipsticks and lip glosses include different chemicals. Over time, some are able to enter into chemical reactions with oxygen or oxidize. Therefore, the product becomes unusable due to drying or spoilage.
Many manufacturers increase the shelf life of lipstick by adding oxidation resistant components. But there are applicable standards for this product. Moreover, manufacturers can not violate them.
What influences him?
The shelf life of lipstick is determined by the composition. If there is castor oil in the solid base, which is resistant to oxidation, then this period increases. The more safe antioxidants present in the product, the longer they last. The same functions are performed by preservatives.
The types of cosmetics are also important: lipsticks last longer than lip gloss. Unopened lipsticks have a longer shelf life. The application method, storage conditions, and hygiene rules are also taken into account.
Structure
Since the modern beauty industry is actively developing, new lipsticks that have perfect aesthetic properties are constantly being produced. Each cosmetic company adds its own substances to this product. But most tools have the following components:
- Waxes that are hard and semi-solid. They are added in an amount of 2 to 13%. They are required to bind other components and maintain hardness. To eliminate dullness, waxes are added to beeswax, which are made from palm leaves, cacti or roses. With their help, cosmetics will be resistant to temperatures, not smeared, retains saturation. All types of wax need to be added in a certain ratio. For example, the volume of beeswax is usually not more than 2 - 5%, since it makes the lipstick dull. To add shine, Cadelian wax is used in an amount of 13%. Carnauba wax is used in an amount up to 5%. Some companies use synthetic waxes instead of natural waxes.
- Lanolin. This substance and its derivatives are considered components that are made from sheep's wool. This substance has disadvantages - an unpleasant taste, smell and high stickiness. Often, lanolin leads to allergies in the form of contact dermatitis. Usually, about 5% of lanolin is present in lipsticks, and in gloss it reaches 70%.
- Dyes. Used to give color. Natural dyes used to be vegetable juices, natural herbs, as well as insect pigments. Modern cosmetics include chemical dyes from the D&S category. This is a list of dyes that are allowed in the pharmacy. Each shade has a personal serial number. Percentage indicates color saturation.
- Oils - synthetic and natural. With their help, varnishes and pigments do not precipitate. Perfume oils are considered solvents of lipstick components and make up to 30% of lipstick volume. Typically, cosmetics use sunflower, castor or chamomile oil. With these components, lipstick is easier to apply on the lips. Aromatic oils are added for the attractiveness of the product, its pleasant aroma and taste. Aromatic compositions are fruit aromas and natural esters.
- Pearlescent additives, for example, mica. Added in amounts up to 25%.
- Pine Rosin. Up to 4% is added, for hardness, film-like coating.
- Microspheres. These are small particles that give the product saturation and fat content. They have a positive effect on the skin and include special chemical components, vitamin E and folic acid.
- Mineral pigments. This is iron oxide or titanium dioxide. Used to obtain pink tones and ease of application.
- Boric acid. Gives shine and iridescent pearlescent lipstick. For these purposes, microparticles of quartz or mica are used.
- Antioxidants. They are added up to 0.8% as a necessary component in all types of lipsticks. Antioxidants protect against oxidation of natural products. Usually this role is performed by the substance propylgillate.
In addition to the required components, additional ones are added. It can be collagen, aloe vera, sunscreen and other components. Product properties also depend on the composition.
What is specified in state standard specifications?
You can find out about the shelf life of lipstick from GOST. In Russia and the CIS countries, quality standards are in force according to which cosmetics should be produced, stored and transported. The main norms are in:
- GOST R 52342-2005.
- GOST 31649-2012.
They are called “Products of lipstick-based makeup.” According to these standards, the shelf life of lipsticks and glosses is approved by the manufacturer.
The timing
The period before the start of use is fixed on the packaging by all manufacturers, and after opening it by the majority. What is the shelf life of lipstick? The standard dates are as follows:
- Solid lipstick is stored up to 3 years before opening. And what is the shelf life of lipstick after opening? It is 1 year old.
- Liquid gloss - 3 years and 10-12 months, respectively.
- Lipstick-pencil - 3 years and 18 months.
- Lipstick felt-tip pen - 3 years and 1 year.
- Tint - 36 and 12 months.
- Lipstick-varnish - 3 years and 12 months.
- The shelf life of hygienic lipstick and balm is 3 years and 12 months.
- Liquid matte - 36 months and 12 months.
In the end, it all depends on the type of cosmetic products. This is important to consider when choosing these products. After the expiration date, mandatory disposal of products is necessary.
Different manufacturers
What is the shelf life of lipsticks in popular companies? Storage period may vary:
- Lipsticks "Avon" and "Oriflame" have a shelf life of 3 years.
- Dior products have 18 months.
- Maybelline products last 36 months.
- L'Oreal lipsticks are suitable for use up to 36 months.
- Pupa cosmetics can be applied up to 24 months.
- Faberlic lipstick is used up to 24 months.
Thus, almost never the shelf life of funds of different brands is more than 36 months. And some firms reduce it to 2 or 1.5 years. After opening, it is advisable to stop using cosmetics after a year.
Storage rules
Lipstick is stored at room temperature. Like other decorative cosmetics, it must be protected from the sun, moisture, installation near sources of elevated temperatures. A prerequisite is tight closure after use.
Is refrigeration allowed?
This storage option allows you to increase the shelf life. In this case, it will be 1.5 times more in comparison with storage at room temperature.
But temperature changes negatively affect cosmetics. Therefore, a single move to the refrigerator can lead to the fact that the product will need to be left there constantly, otherwise it will deteriorate.
What is observed over time?
Lipstick is a contact tool, so with prolonged storage, many microbes appear in it. Long term operation can disrupt its structure, change the chemical composition. Over time, cosmetics are oxidized from oxygen and become unusable.
Signs of Corruption
Since the composition contains oils and fats, an unpleasant odor is capable of indicating spoilage. Dried, cracked or leaked product should not be used. It must be urgently thrown away. Damage can be understood by:
- change in taste and color;
- the appearance of white plaque;
- the appearance of droplets of liquid on a decorative product.
When cosmetics are poorly applied, rolled off, become very dry or viscous, this indicates its deterioration. You should not continue to use it, it is better to purchase a quality product.
Danger of delay
Some believe that the use of expired funds has no consequences. But this opinion is erroneous. So the decorative properties and benefits are reduced, in addition, the product can be hazardous to health. Microbes on old cosmetics can cause infections of the skin of the lips, and expired substances lead to allergies.
An unpleasant consequence is the development of cheilitis, an allergic disease, which manifests itself in the form of lip cracks, exfoliation of the upper epidermis, and redness of the lip rim.
Lipstick, gloss and other lip products - this is the cosmetics whose shelf life must be observed. Since it is applied to the border of the mucosa, and some penetrates inside, then you need to use fresh means.
