In recent years, Japanese consumers and consumer protection groups have gradually paid attention to the problem of "scent harm". The so-called fragrance damage refers to the symptoms of headache, disgust, allergies, etc. when people hear too much fragrance on their body. Because it is difficult to get the single product, the fragrance is heard every day, so the source of the problem is difficult to clear. When medically speaking, I have a chemical allergy in CS (Chemical sensitivity).
These problems seem to have increased trends in recent years, so even some consumers in Japan form "Eliminating Incense and Eliminating Correspondence Association" or victims form "Golden Sparrow Association" to communicate or promote consumer protection. I think this is related to the special strong fragrance or long-lasting fragrance in recent years. In fact, many consumers like this selling point, especially the market for laundry and soft essence. Since the 1990s, the soft essence of clothing such as Xiong Xbe has been looking for it, the main sales focus has been on the fragrance of clothes and soft essence. The sales volume of soft essence has increased in recent years. Especially in recent years, the uniquely popular fragrance has lasted for a long time, so many products claim to be able to keep fragrance for 10-12 hours. To make the fragrance more lasting, not only the amount of fragrance may be increased, but also some modifications in the fragrance molecules, but this modification will expose us to more chemical substances.
{design mainly includes the following methods. 1. The aroma of wood and musk is not as good as the aromatic properties. The aroma is generally lighter and easier to develop. Therefore, if you pair some heavy wood flavors such as sandalwood, musk, frankincense and other flavors in the scent, it can make the fragrance longer, but the fragrance will change, that is, the taste at the beginning will be different from the taste at the end. 2. FragranceSome substances do not have fragrance in themselves, but when they exist, they can make it less easy to develop fragrance molecules. This is Fragrance . Although there are many types of aromatherapy agents with this characteristic, the ones that were widely used before were plasticizers such as DEHP and DBP. Because plasticizers have been determined to have negative effects of interfering with human endocrine, regular products should be avoided now.
3. Microcapsule fragranceThe latest generation of technology currently is microencapsule of fragrances. Microcapsule forms a shell with polymers, and encloses the main ingredients such as fragrances. There are two advantages to this design.
1. The shell can protect the active ingredients and prevent the proactive ingredients from being easily lost.2. The main components of the management can be released slowly, or only under specific conditions.
Therefore, microcapsules can have better control over the protection, transmission and release of active ingredients. If used properly, they can also reduce the amount of active ingredients added or provide better product performance. Therefore, many products, including agricultural medicine, paints and mattes, cosmetics, household goods, personal products, food, health products and pharmaceuticals, apply this technology in large quantities. Therefore, most of the long-acting and fragrant soft essences and laundry essences are used for the fragrance of microcapsules. Therefore, the fragrance can be attached to the material for a long time, and the second is that it can be controlled under special conditions such as when the clothes are rubbed or the temperature rises, the micro capsule will be continuously broken and spice molecules will be released.
Microcapsule Flavors Careful FormaldehydeIn the microcapsule application of fragrances, the shell can use many polymers, such as powder, gel, etc., but the most widely used shell material is melamin-formaldehyde resin (melamin-formaldehyde polymer). Melamine-formaldehyde polymers have many advantages in microcapsules, such as easy production, easy to control rupture, and low cost. However, in recent years, melamine-formaldehyde polymers used in foils and other consumer goods and building materials have been proven. With the progress of time, it will release trace amounts of floating formaldehyde, which has gradually caused consumers to be worried about the exposure of formaldehyde.
Formaldehyde is a recognized first-class carcinogen and can also cause irritation and allergies to the human body. Therefore, in various industries, people are trying to reduce the risk of human contact with formaldehyde. Although it is currently believed that the amount of formaldehyde placed in such microcapsules is a trace amount, but there is still very little specific information, so it is difficult to determine whether these products are really risky to human health or environmental structure. But since consumers have this kind of concern, it has further prompted the fragrance industry to look for low-formaldehyde or no-formaldehyde alternatives.
Prevent fragrance damage, how can we do itSo it is still difficult to determine whether this trace amount of formaldehyde causes fragrance damage at present, because the fragrance molecules are quite complex, coupled with the emulsifiers used during microencapsulation, melamine monomers produced, etc., all cause the complexity of these chemical molecules. Therefore, we can do at least the following three points:
1. There is no need to deliberately pursue very long-lasting fragrances.2. When buying soft solute or laundry serum, it is best to try it in small quantities first to make sure that there will be no adverse reactions in your body before using it formally.
3. The dosage is as recommended. Don’t pour too much in just to make it more fragrant..
As Japanese doctor Eiro Kochi Hospital, a national medical institution specializing in chemical substances, said that the number of people who are not suitable for physical condition due to intoxication is increasing, and the impact of chemical substances cannot be predicted. It is impossible to predict when they will develop the disease, and the chances of getting such symptoms under long-term contact with chemical substances will increase. The reason why fragrance products such as softeners are sold is because of the needs of consumers. First of all, I hope everyone can understand that some people are suffering from such risks due to the fragrance. Japan's well-known medical professor Sakabe also said that chemical allergies will make you completely fine last year. This year, you will suffer from symptoms and become headaches, and there are a lot of uncomfortable symptoms.
Microscopic fragrances are also the source of plastic particlesIn fact, this type of microscopic fragrances also has a disadvantage, that is, they all belong to plastic polymers, and therefore microplastics. According to Waseda University research, generally 5 ml of soft essence has up to 1 million micro-coated capsules. When we wash clothes, only 20% of the micro-coated capsules will be attached to the clothes, and the other 80% will be exiled to the sewers or the ocean. This is also a major source of micro-plastics, so we must also pay attention to its permanent impact on the environment.
