Terephthalylidene Dicamphor Sulfonic Acid
Phenylenemethylenedicamphor sulfonic acid is used today, and it is very useful. This substance is commonly found in sunscreen products and is essential for protecting the skin from sunlight.
In sunlight, ultraviolet radiation can cause various diseases of the skin, such as sunburn, tanning, and even skin cancer. p-Phenylenemethylenedicamphor sulfonic acid has excellent ultraviolet absorption properties. It can efficiently absorb ultraviolet energy, convert it into heat energy and dissipate it, so that the skin can be protected from excessive ultraviolet rays.
In the preparation of sunscreen products, this acid can be stably stored in the system, in coordination with other ingredients, to build a perfect sunscreen structure. Whether it is a lotion or a spray, it depends on its efficacy to ensure that the user's skin remains healthy when exposed outdoors.
And because of its relatively stable chemistry, it is not easy to decompose and fail under environmental factors, so it can play a long-term role in sun protection. And it is suitable for all types of skin types, so it will not cause allergies and other discomforts. There are many users, and it is an indispensable ingredient in the field of sun protection. In short, p-phenylene dicamphor sulfonic acid plays a great role in sun protection and skin protection, ensuring everyone's skin health. It is widely used in the field of daily chemical industry.
Is Terephthalylidene Dicamphor Sulfonic Acid Safe for Skin?
The use of terephthalylidene dicamphor sulfonic acid is also a sunscreen. As for whether it is safe for the skin, it needs to be investigated in detail.
The inspection of various things in the past that involve the safety of the skin must be handled with caution. Although this acid is used for sunscreen, its properties should not be ignored for the skin. Those who cover the skin, the barrier of the human body is sensitive and fragile. If the thing used is uncomfortable, it may cause various diseases, such as allergies and inflammation.
Ancient tests often follow a gradual method to detect their long-term effects. The same is true for terephthalylidene dicamphor sulfonic acid. Examine its ingredients in detail, study its relationship with the skin, and observe its changes in people of different skin types. And it is necessary to observe whether it penetrates into the deep layers of the skin when used externally, causing hidden diseases.
And observe the previous experiments, and refer to the examples of many people, not only one or two. Yu Si acid, it is also appropriate to gather the feedback of users and comprehensively consider, in order to know whether it is safe or uneasy in the skin. However, the current knowledge may not be well understood, and it still needs time and research to clarify the details and determine whether it is safe in the skin.
Terephthalylidene Dicamphor Sulfonic Acid is commonly added in sunscreen products
In sunscreen products, the amount of Terephthalylidene Dicamphor Sulfonic Acid commonly added is not fixed, and often varies according to a variety of factors.
This sunscreen has a good effect and can effectively resist ultraviolet rays, but the amount added must be carefully considered. If the amount added is too small, it may be difficult to provide sufficient sunscreen protection, resulting in insufficient sunscreen effect. On the contrary, if the amount added is too much, or it may cause skin discomfort, such as allergies, irritation and other conditions.
Generally speaking, in most sunscreen products, the amount of Terephthalylidene Dicamphor Sulfonic Acid added is between 0.5% and 10%. For sunscreen products used in daily commuting, since the sun protection index requirements are not very high, the addition amount may be about 0.5% - 3% to provide moderate protection for the skin. For high-multiple sunscreen products used in long-term outdoor activities, in order to achieve a higher sun protection index and meet the needs of stronger sun protection, the addition amount may be increased to 5% - 10%.
However, the specific addition amount of the product, in addition to considering the sunscreen needs, it is also necessary to take into account the compatibility of other ingredients, product texture and stability. Different brands and types of sunscreen products, due to different formula designs and target audiences, will also add different amounts of p-phenylmethylenedicamphor sulfonic acid. Therefore, there is no fixed standard for the exact addition amount, which depends on the actual situation of the product.
Terephthalylidene Dicamphor Sulfonic Acid
Terephthalylidene Dicamphor Sulfonic Acid is a commonly used sunscreen. The principle of its sunscreen is to absorb or scatter ultraviolet rays through the characteristics of the molecular structure.
The molecular configuration of this substance is unique, containing specific functional groups and conjugated systems. Under ultraviolet radiation, electrons in molecules are energized and transition from the ground state to the excited state. During this process, the energy of ultraviolet rays is absorbed by molecules, and then the energy of ultraviolet rays is converted into the energy of molecular vibration or rotation, and then the purpose of absorbing ultraviolet rays is achieved.
For example, its conjugate system can make the π electron cloud more delocalized and broaden the wavelength range of ultraviolet absorption. And because of the structure of specific functional groups and molecules as a whole, they can be moderately combined with the skin surface and distributed evenly, forming a protective layer on the skin surface to effectively resist the damage of ultraviolet rays to the skin. Whether it is medium-wave ultraviolet rays (UVB) or long-wave ultraviolet rays (UVA), both can be absorbed to a certain extent, thereby reducing the risk of damage to biological macromolecules such as skin cell DNA and proteins by ultraviolet rays, protecting the skin from sunburn, tanning, photoaging and other adverse effects, achieving the effect of sun protection, and creating a safe protective barrier for the skin.
Does Terephthalylidene Dicamphor Sulfonic Acid Interact with Other Sunscreen Ingredients?
Terephthalylidene Dicamphor Sulfonic Acid is one of the ingredients in sunscreen. In the construction of sunscreen formulas, there are often interactions between various sunscreen ingredients.
This ingredient interacts with other sunscreen ingredients, or due to molecular structure and chemical properties. In terms of its chemical structure, Terephthalylidene Dicamphor Sulfonic Acid has a specific functional group, which can attract or combine with the functional groups of other sunscreen ingredients through weak interaction forces such as hydrogen bonds and van der Waals forces.
For example, some organic sunscreen ingredients, whose molecules contain hydroxyl, carbonyl and other groups, can form hydrogen bonds with the groups of Terephthalylidene Dicamphor Sulfonic Acid, thereby changing the physical and chemical properties of each other. Or in terms of photostability, each sunscreen ingredient may have a synergistic effect. Terephthalylidene Dicamphor Sulfonic Acid can be combined with some ultraviolet absorbers to broaden the spectral range of ultraviolet absorption and improve the overall sunscreen effect.
However, the interaction is not all beneficial. Sometimes the solubility is changed due to the interaction. If the solubility is poor in the formula, or the separation and precipitation of ingredients are caused, the stability and use effect of the product are affected.
And the ratio of different sunscreen ingredients also affects the interaction. When the ratio is appropriate, a good synergistic effect may be exerted; if the ratio is misaligned, a negative effect may be caused. Therefore, in the research and development of sunscreen products, it is necessary to carefully consider the interaction between Terephthalylidene Dicamphor Sulfonic Acid and other sunscreen ingredients, and optimize it through many experiments to obtain a sunscreen formula with excellent performance and stability.
