  • Is it advised to use 4-5% NACL in facewash as is used in this formula from Innospec?

    This is an example facewash formula from Innospec. It has 4% NACL in facewash.

    I am making facewash too but as i use ≤8% surfactants it doesn’t thicken enough with 2% NACL so i use polymers to increase viscosity.

    Question: is 4-5% NACL safe in face and body wash or shampoo to adjust viscosity?

    it is not problematic in a way of health hazard or anything but it can lead to Irritation at the eyes and Teardrops due to the salt content.

    Thanks 
    My concern was also eye and face irritation or drying. 

    Interestingly 2-5% NACL functions as OTC medicine for eyes.

    The ocean has about 3.5% salt so it’s not much worse than that

    @Perry thanks.
    Does 3-5% NACL in cleansing product has any benefit or functionality other than viscosity adjustment?

    I don’t know - but probably nothing that would be consumer perceptible in terms of cleaning.

    In the past, I worked on a product that used a similar base to this which used 4% NaCl. It wasn’t just used based upon the distributers guidelines, but they did an old-fashioned salt curve. As far as I know, the product had great reviews and nobody mentioned any issues. The only negative we had to overcome was the misinformation regarding salt and “drying of the hair.” That came from marketing, not empirical testing.
