ChemWorld Methylene Blue is an ultra-pure, pharmaceutical-grade form of Ph.Eur. Despite the supplier's testing, we verify these tests in a Polish laboratory. We always do this to ensure we deliver a product to our customers without impurities. Tests have shown no heavy metals or other contaminants.

Compliance with the requirements (Ph. Eur.) proves that our methylene blue is manufactured and tested to the highest standards, free from harmful contaminants and heavy metals such as lead, arsenic, cadmium and mercury.

Product advantages:

✅ Professional pipette - dropper

✅ Pharmaceutical purity grade Ph.Eur.

✅ Product tested in a Polish professional laboratory

✅ Correct solution recipe

✅ Laboratory-confirmed Methylene Blue content

✅ Laboratory-confirmed absence of heavy metals

We also verified in a Polish laboratory that our formula was correct and that customers were receiving exactly 1% methylene blue in an aqueous solution. The test showed that our methylene blue solution was no less than 1%, and even slightly above. This guarantees the declared potency.

Properties:

  • Solubility:  freely soluble in water and alcohols, forms an intense blue solution.         
  • PH dependence:  its color changes depending on the environment - in acidic solutions it takes on a cationic form (more intensely blue), and in alkaline solutions it can be reduced to a colorless leuco derivative.     

Reduction and oxidation:          

  • It can be reduced to methylene leucoblue, which is colorless, but reoxidizes to methylene blue upon contact with oxygen.
  • It acts as an electron acceptor and donor, which is why it is used as a redox indicator.      

Reactivity: 

  • In a reducing environment it can be transformed into methylene leucoblue, which is used in chemical reactions and biological research.
  • It can react with a variety of biological substances, such as proteins and nucleic acids, making it useful in microscopy and molecular biology.
  • It is relatively stable, but may degrade in the presence of strong oxidizing or reducing agents.     

Applications: 

  • Redox indicator – used e.g. in chemical analyses and biological tests. 
  • Biological dye – used in microscopy to stain preparations. 
  • Application in aquariums – used to color water. 
  • Fluorescence, exhibits fluorescent properties under certain conditions.

PRECAUTIONS:  If swallowed, do not induce vomiting; rinse mouth with water. Seek medical attention immediately. In case of contact with eyes, rinse with plenty of water and consult an ophthalmologist immediately. In case of skin contact, remove contaminated clothing and wash skin thoroughly with water. Immediately immerse contaminated clothing in water and rinse thoroughly.

STORAGE:  Store in a dry, dark and cool place, out of reach of small children.

Great product! Highly recommend! Worth the money
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Our family absolutely loves Alba sunscreen! It’s light, not super greasy, and smells really good. Everytime I see it on sale, I buy more of it! My husband is a red head, and he has to wear sunscreen all the time, and he prefers Alba brand over any others. Great Product!

Like the sunscree - not the spray can
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Sunscreen itself did a great job with our snorkeling and scuba diving. Long lasting and didn't rub off in spots where masks and other things can leave spots unprotected. However, the spray can itself was difficult. Even when being sure it was completely in the unlocked position, it would take me two thumbs at full pressure to get it started spraying at times. Definitely, only a couple of us in the party were the appliers as we could get it started.

Love it! Eco-friendly and Easy-to-Use Spray
Style: SPF 50, Size: 6 Fl Oz (Pack of 2), Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I really like the Alba Botanicals Coconut Clear Spray! Not only does it give me a refreshing coconutty vibe, but it’s also biodegradable and cruelty-free, which is important to me. 🐰♻️ The spray-on application is a breeze, and I love how it doesn’t leave that annoying greasy feeling on my skin. It absorbs quickly and leaves my skin feeling soft and nourished. Perfect for those sunny beach days or any time I need a quick spritz of hydration. I highly recommend this coconut clear spray to everyone who values eco-friendly choices and easy-to-use skincare products.

Great product, bad packaging
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
I love this sunscreen! I use it on myself and my child and it works very well. However, the spray nozzle on one of the cans is locked and it will not work. I have tried to turn the lock, lift it up, etc., to no avail. This item is also not returnable. $20 for 1 can of sunscreen is quite expensive.

Great product
Style: SPF 50, Size: 6 Fl Oz (Pack of 2)
Product is great with good coverage and ease of use. Much better than comparable products because it is very light feeling and doesn't leave a heavy or sticky residue on your skin. Perfect protection for anyone who burns easily or fair skinned. However I paid for the extra rushed 3 day shipping and it was delayed and I wasn't reimbursed the extra shipping charges even though it arrived 6 days later.
