Why are cold processed soap safe to use.
Hi,
I am a maker of coldprocesed soap and have been using it for more than 8yrs. I could say my skin is good for my 40+ age. My skin care routine is washing face twice a day(morning and before bed) , followed by day cream and night cream respectively with extra sunscreen in the morning. I dint use any serum, scrub, easence, toner.
My question is why cold processed soap have such bad reviews when i find that is good on my skin and my family’s
My explanation is, if our skin has a pH of approx 5.5 and soap is approx 9 and when they combine, they would be a new ph which is would be a favourable number to our skin.
Pls confirm my thought.
Thanks in advance.

I think the answer to your question lies in the fact that our skin is very resilient. We abuse it in every way….exposure to low humidity with heated and air conditioned homes, and it adapts…. we abuse it with high pH products likes soap, and it immediately adapts and starts to lower the pH back to were it is comfortable. Almost whatever we throw at our skin….it overcomes to some degree. In no way shape or form…does the skin stay at the higher pH that soaps takes it to….it immediately uses all its resources to return to the correct acidic pH.
I think you will find many that are deeply entrenched in skin care….do not use high pH soaps for this very reason.
Our skin has something called an ‘acid mantle’ which is our first and foremost barrier to the world. This might be a starting point for your journey and study of skin. Yes, skin can recover from being soaped….but why? There are many theories, and just as many opinions, so you will always be able to find the crowd that believes in your theory, if you want folks to sing ‘Kum ba yah’ with you on soap….just hang on a soaping site. 🙂

There is peer-reviewed scientific literature that demonstrates that skin can recover quickly from high-pH soap (9.5 pH).
With my experience as
the co-founder of a skincare manufacturing factory in Viet Nam and Malaysia
since 2006, we produced a lot of soap under GMP manufacturing standards. We exported globally under our brand and other brands. These soaps were enormously popular.And our secret. Firstly, very high-quality ingredients. Second, attention to detail in the formulation of our soap bars. For example, we spent 12+ months formulating and testing our first bars.

I believe that is what I said…but when I read this research…I was always appalled at HOW LONG it took to auto-correct. I guess quickly is an arbitrary term.
Good thing I don’t sell soap….so I can choose as I see fit. (20 years and counting….)

Though I didn’t not get the answer I was looking for ( what will be pH, when the pH of skin and pH of cold processed soap combines?) I came to know u don’t use or make soap.
However, I believe I am in the right site asking right question as soap is skincare product, which is formaluated to get a desired skin product after some chemical reaction. So don’t judge me.

To your question, you’ll have a New pH is you mix solutions. While your soap once diluted in water will have a pH, the acid mantle on your skin will be in a somehow solid crystalline state. So at the end, rather than mixing, the surfactants from your soap will strip off the acid mantle on your skin.
Now, that you didn’t experience any issue with the use of soap doesn’t mean some other people won’t either. That’s one of the reasons clinical trials are done with a lot of people.

“Safe”?
pH - not at issue. Skin has no pH per se but techniques that propose to measure find it effectively buffered.
Fatty acids in soap - short chain are more biologically active - C12 may be more irritating on skin than longer chain.

I have found that anecdotally working with Dermatologists and their products that skin without an underlying disease state will not generally have an issue. I did have a client contact me due to an Adverse Incident in a Peds patient with Eczema who could not tolerate saponified soaps. The Dermatologist did relay that he has seen this issue numerous times in the Clinic.
As a Formulator I am biased toward surfactant systems. It will open you up to a great deal more options regarding water-soluble raw materials.
