@Graillotion did you add %0.1 active GLDA or solution?
If solution, how much GLDA is in the solution?

@Pharma can I ask for achieving what effect did you suggest silicone elastomer instead of HPC?

@Microformulation my focus is less on foam and more in preventing calcium attachment to hair and removing attached calcium from hair. Would it be helpful for this?

@Pharma @PhilGeis this product doesn’t have anything other than water and chelating agent. Why would microbes grow there?

How much phytic acid and hexametaphosphate makes 1L hard water soft?

@Pharma no, pH of the Shampoo is 5.

I thought the pH of Shampoo and chelating agent in Shampoo will have effect in hardness of water with which we wash our hair. Is my thoughts wrong?

I don’t think GLDA is compatible with cationic surfactants. You can check the compatibility first.

@Pharma ohh

Should the pH be higher or lower for citric acid to complex calcium?

@Pharma by effectively i mean effective when shampooing the hair in very hard water.

What is the lowest pH at which EDTA can chelate calcium effectively in very hard water for Shampooing?

How about citric acid @ ph 5 for calcium chelating?

@Pharma how about fragrance oils?
Do they also penetrate skin easily and pass into the bloodsteam and excrete by breath?

Don’t use chelating agents like EDTA or sodium phytate and citric acid. Adjust the pH with lactic acid. Use caprylhydroxamic acid if you need a chelating agent in the Product.

I am very skeptical about the effectiveness of essential oils in skincare products. For me they act like fragrance, only appear to be natural. But i do believe all kinds of scent can play with our moods. For example lavender can make us feel calm, citrus scent is energizing, creamy scent like chocolate or vanilla make us feel hungry. Any strong scent can give us a headache… But thats just about it.

Yesterday, one of my family members tried an essential oil based product on her son (2yo) who was having cough with phlegm. After rubbing the product on his chest, the son coughed out lots of phlegm. It was like magic! Was it a coincidence, or did the product really work? The product is a cosmetic, but with lots of drug claims. I suspect it’s the rubbing motion that was responsible for the magical moment? But these kinds of product reviews sometimes make me question my view on essential oils. Maybe they do work? Or maybe just olive oil or any other massage oil can give the same result? It’s the rubbing that works? Or maybe the scent of the essential oil blend makes us wanna puke phlegm?

I always think of topical cosmetic products to work by getting absorbed into the epidermis or forming a layer on the skin. But the scent of the product can affect our experience of using the product too.. How far can it (the scent) affect us / our brain?

What is your opinion on skincare products with essential oils and drug claims (help reduce cough, phlegm, etc)? Yes, they are wrong for using drug claims, but i’m interested to know how far essential oils aromatheraphy can affect us.. All those claims on aromatheraphy, are they real?

Hope you can share your opinion on this. Thank you.

How does this product smell?
Like lavender? Thyme? Or something else?

@Perry @ngarayeva001 @Pharma thanks
My question is particularly about MCT oil vs Caprylic/Capric Triglyceride. They have samse INCI, same CAS number and same IUPAC nomenclature “decanoic acid;octanoic acid;propane-1,2,3-triol”. Even some manufacturers say these two are the same.

So What makes these two Products different? And what should i check to know the product i am purchasing is MCT oil or Caprylic/Capric Triglyceride?

It is unstable emulsion and creaming is happening.

leaf water as first ingredient and not stable emulsion. preservatives don’t work correctly in my experience in unstable emulsions. How much is the shelf life of this product?
