July is the peak of summer, and during hot and humid summers, food can become a fertile medium for bacteria at any time. Especially fruits and vegetables, if newly purchased fruits and vegetables are not stored in the refrigerator, they can only be stored for one day. And every summer, there are many cases of diarrhea caused by “eating poorly”, both adults and children, often mistaken for eating too “cold”. In fact, low-temperature food or beverages do indeed cause some friends to have faster intestinal peristalsis, but generally do not cause people to run to the restroom several times a day. So at this point, the first thing to consider is the intestinal infection caused by food hygiene. Is the food that is consumed rotting and spoiling? So how can we eat fresh fruits and vegetables in the hot summer?

At this point, the first thing we think of is refrigerator storage. However, there are many kinds of food and drinks stored in refrigerators, among which there are many foods that “inject bacteria” into refrigerators, such as eggs that may carry salmonella, and raw meat, fruits and vegetables that may carry pathogenic Escherichia coli, pathogenic Staphylococcus aureus and parasites. And the refrigerator also has a shelf life for preservation. Generally, food that takes 2-3 days must be eaten, otherwise it will rot in the refrigerator over time. At the same time, the refrigerator also has a certain amount of storage space, which is only used for household use. If it is a large supermarket, how do we keep the food fresh from the source merchants we purchase?

With the development of economic globalization, the import and export of fruits and vegetables has become the norm. In the face of this situation, we have to study a new type of preservative- -1-MCP fruit and vegetable preservative. Once the product was developed, it received a high response. Because this is a non-toxic, highly safe, and significantly effective preservative. Next, let’s talk about the ingredients of 1-MCP fruit and vegetable preservative.

What is 1-Methylcyclopropene?

1-Methylcyclopropene, abbreviated as 1-MCP in English, CAS 3100-04-7 chemical formula is C4H6. Under normal temperature and pressure, the appearance is colorless gas, non-toxic and tasteless, with a density of 0.838g/cm3. It is a very active Cyclopropene compound. 1-Methyl Cyclopropene is mainly used as a plant growth regulator and is widely used in the field of plant preservation. It has the advantages of low consumption, good preservation effect and high safety.

Characteristics of 1-MCP

1-MCP can inhibit the release of ethylene by plants themselves, and also block the binding of ethylene to related receptors in plant cells, thereby inhibiting the ripening effect of ethylene. Therefore, the application of 1-Methylcyclopene can effectively prolong the maturation and aging process of plants, thereby prolonging their shelf life, reducing corruption and waste during transportation and storage, and extending the shelf life of goods.

Applications of 1-MCP

1-MCP can be applied to the preservation of fruits, vegetables, and flowers to prevent plant wilting. For example, when applied to fruits and vegetables such as apples, pears, plums, kiwifruit, and tomatoes, it can delay their ripening, reduce water evaporation, and maintain their hardness, taste, and nutritional composition; In terms of flower preservation, it can maintain the color and fragrance of the flowers. In addition, 1-Methylcyclopene can also improve plant disease resistance. 1-Methylcyclopene is a new milestone in fruit and vegetable preservation after modified atmosphere preservation.

After the epidemic, the economy recovered, and the development of global trade was gradually expanding. Every year, each country would produce a large number of local fresh fruits and vegetables. Due to the imperfect development of agricultural cold chain logistics, about 85% of fruits and vegetables used ordinary logistics, resulting in a large number of decay losses, which also provided a broad market space for the promotion and application of 1-methyl Cyclopropene. Therefore, it can be seen that 1-MCP has broad development prospects, not only for various respiratory climacteric fruits and vegetables, but also can effectively extend post harvest storage and shelf life, especially for ethylene sensitive fruits and vegetables, and can maintain the original quality of fruits and vegetables for a long time.

Many beauty enthusiasts spend a lot of time and energy on skin management, but the effect is minimal, and there are still various skin problems, deeply troubled by problematic muscles. Especially for girls, regardless of age, it is human nature to love beauty. Why do you do enough hydration work for your skin every day, or do you get dry and shaky? Why is the skin constantly prone to acne, which persists for a long time? Why do oil and long spots often accompany skin travel? Next, I would like to share —Squalane, a common ingredient in skin care products, and I hope it will be helpful to you.

What is Squalane?

Squalane CAS 111-01-3 is a colorless liquid. Most of them are found in shark Cod liver oil, which is made from squalene through hydrogenation, and a few of them are from olive oil and human fat. The predecessor of Squalane is squalene, but it does not have the antioxidant capacity of squalene, nor can it be converted into squalene on the skin, which does not stimulate and sensitize the skin. Squalane is a stable, well absorbed oil that can moisturize the skin and has good affinity for the skin. It is a very safe cosmetic raw material.

Squalane is a component in many skin care products, which has the function of beauty and skin care, such as relieving dry skin, softening skin, protecting skin, delaying skin aging, and improving Melasma.

1. Relieve dry skin

Squalane is an inherent ingredient in the skin, which can alleviate dry skin, nourish skin, and have a good moisturizing effect.

2. Make the skin soft

Squalane has good permeability and can enter into the skin, becoming softer, more tender and younger.

3. Protecting the skin

Squalane will form a protective film on the skin surface, which has the effect of water locking. Especially suitable in dry and windy seasons to avoid skin damage from the external environment.

4. Delaying skin aging

Squalane can inhibit skin Lipid peroxidation, promote the proliferation of skin basal cells, and alleviate skin aging.

5. Improve Melasma

With the growth of age, many women have Melasma on their faces. Skin care products containing Squalane can be used, because the shark pattern has the effect of reducing melasma.

What are the characteristics of Squalane?

Squalane is a kind of stable, skin friendly, soft, mild and active high-end natural oil. Its appearance is colorless transparent liquid with high chemical stability. Squalane is rich in texture and non greasy after dispersed application. Squalane is a kind of oil with excellent sense of use. Due to its good permeability and cleansing effect on the skin, it is widely used in the cosmetics industry.

Squalane is a natural component of sebum, which can be considered as bionic sebum and can help other active ingredients penetrate; Squalane plays a crucial role in skin barrier repair.

Squalane is extremely mild because of its stability and high purity, less impurities in the product, and it is a part of the skin. It can be applied to sensitive skin and baby skin without causing acne. It has no sticky feeling during and after application, and has a soft cushion after absorption, improving the softness and moisturizing feeling of the skin.

Squalane is a saturated alkane. Under high temperature and ultraviolet radiation, it will not be rancid like vegetable oil. It is stable at -30 ℃ -200 ℃ and can be used in thermoplastic products such as lipstick. Squalane can be used in hair care products to increase brightness and alienation; Not irritating to the skin, not allergenic, very safe, especially suitable for baby care products.

Although there is only one word difference between Squalane and squalene, Squalane has more advantages, with good skin affinity, permeability and moisturizing effect. But don’t blindly deify the efficacy of Squalane. When buying skin care products containing Squalane, you should consider the cost performance ratio. Squalane is not recommended to buy products with inflated prices.

With the arrival of summer, more and more people are paying attention to their skin, especially female friends. Due to excessive sweating and strong oil secretion in summer, combined with strong ultraviolet rays from the sun, it is easy for the skin to sunburn, accelerate skin aging and pigment deposition, and in severe cases, even develop spots. Therefore, summer skincare is particularly important. This article starts from three aspects: sun protection, cleaning, and moisturizing, and introduces how we should take care of our skin in summer?

Sunscreen

Sunscreen is one of the essential steps in summer. Generally speaking, it is widely believed that sunscreen is to prevent sunburn. In fact, preventing sunburn is only a superficial phenomenon, and it is to help us prevent skin aging, pigmentation, skin diseases, etc. Therefore, using sunscreen skincare products in summer is essential. When choosing sunscreen products, it is best to choose sunscreen with an SPF value greater than 30. During use, attention should be paid to the completeness and uniformity of the application to achieve better results.

Cleaning

In summer, everyone knows that sweat and oil are secreted vigorously, and the body is prone to sweating and acne. Therefore, the cleaning steps in summer are also crucial, especially after applying sunscreen products, it is important to clean and repair before going to bed.

The correct method is: 1. Before cleaning the face, you need to wash your hands to remove bacteria. 2. When cleaning, you need to wash your face with warm water, as the temperature of the water can affect the skin’s water and oil balance. 3. If you are applying makeup. Make up removal must not be omitted, and after cleaning, use toner facial mask to repair. 4. According to different skin types, choose your own cleaning products. Mild facial cleanser is more suitable for summer.

Moisture

The high temperature in summer will lead to water evaporation, and the skin is more prone to water shortage. Proper hydration can help the skin maintain water oil balance. It is recommended to use spray moisturizing or moisturizing facial mask. To choose a moisturizer that is suitable for oneself, it is necessary to identify the skin type and issues, as well as the skin needs after cleansing, in order to be more effective in moisturizing.

However, how to choose cosmetics that are suitable for oneself has become a challenge for most girls. In stores, we often see many girls feeling distressed, and there are also many sales guides promoting their products. What ingredients of cosmetics do we choose that are beneficial for our skin? We all know that herbaceous plants are pure natural and non irritating Faced with increasingly healthy lifestyle habits, experts have developed the application of corresponding ingredients extracted from herbaceous plants in whitening and anti-aging cosmetics. The ingredients of plant extracts are more gentle and efficient than those synthesized by chemical synthesis. Below, we will introduce what plant extracts are.

What is a plant extract?

Plant extracts refer to substances extracted or processed from plants (all or a part of them) using appropriate solvents or methods, and can be used in the pharmaceutical, food, daily chemical, and other industries.

Why choose plant extracts?

With the improvement of living standards, people are increasingly resistant to chemically synthesized products, and more people are pursuing more gentle and efficient skincare. Therefore, plant active substances have become increasingly important. Experts have conducted experiments on some plant extracts. They are not only powerful in basic functions (whitening, anti-aging, anti-oxidation), but also may have additional functions such as soothing and repairing. As long as they are well purified, formula stability and other processes, they are really no inferior to chemical components! One of the most typical examples is the glabridin from liquorice.

In recent years, with the increasing attention paid to natural plant extraction, the market demand for plant extracts may experience significant growth. In response to this phenomenon, our company’s R&D department has developed a series of functional plant extract products:

In short, sometimes we may overlook it due to its name (such as various plant extracts), but the true whitening function, safety and reliability, and so on, still rely on various data to prove. Summer skincare is a task based on the premise of hot weather and unstable temperature. As long as mild and non irritating herbal skincare products are used regularly, and attention is paid to daily care and diet, the optimal skin condition can be guaranteed.

Recently, PCHi2019 was grandly opened in Guangzhou Poly World Expo Exhibition Hall! Although there was a silky drizzle over Guangzhou in early spring, it did not affect the enthusiasm of all the friends!Unilong technical& sales department with our hot products PCMX and SCI achieved an outstanding record.

Tetrahexyldecyl Ascorbate (Ascorbyl Tetraisopalmitate）VC-IP CAS:183476-82-6, is a molecule derived from vitamin C and isopalmitic acid. Pure vitamin C has several drawbacks for cosmetically use, most important of which is the low stability. Chemically modified vitamin molecules are more stable, and pure vitamin is released from the derivatives inside the body. Although VC-IP is one good material as its function(see the following chart),its production capacity is one problem in the market as the complex production technical. This is our important goal these two years. Finally, we overcome the problem and already get the1000kgs/month achievement.
