DIFFERENCE BETWEEN CLEAR HAND WASH,FACE WASH AND BODY WASH

WHAT IS THE MAJOR DIFFERENCE BETWEEN CLEAR HAND WASH CLEAR FACE WASH AND CLEAR BODY WASH 
THE PURPOSE IS ALSO SAME OF ALL THESE PRODUCTS CLEANSING AND FOAMING
PLEASE SHARE IF ANYONE KNOW MAJOR DIFFERENCE 
AND ALSO SHARE SUITABLE  PH OF PRODUCTS

    A face wash contains nearly 10% or less active surfactants , with mild ones .
    Hand wash contains nearly 15% , a showergel contain above 20% activs . 
  • AzizAziz Member
    Hand wash pH range 4.4 to 5.8 , face wash 4.5 to 5.5 , shower gel 5.5 . 
    Shampoo 5.5 to 6.2 as per texts .

    Or there is no difference.  Certainly no major differences.  Really, these can be exactly the same formula marketed in a different way.

    For example, there is no scientific validity that a hand wash needs a pH range of 4.4 - 5.8 and a face wash needs pH 4.5 - 5.5

    These numbers are essentially arbitrary. Same with pH of shampoo and shower gel. 

    In fact, you could make a single formula and call it a body wash, hand wash, facial wash, or even a shampoo.

    I have measured the pH of a soap based shower gel of a multinational company, it read 8.97. So it’s all as @Perry said what the sales brief or the customer demands without flouting the laws and regulations.

    @Perry ;, these are not arbitrary numbers at all . Please test a hand wash which has a pH above 8 and a pH of 5 .  I see the difference between a pH of 5 and a pH 7 in a hand wash in blind study . pH 7 makes hand surface hard for a while . For smooth hand wash pH should around 5 . 
    At least three text book I read where strictly recomand pH of shampoo is 5.5 to 6.2 . If you want I can show you the screen shot . 

    In our hands there are residence bacteria which mantains our hand's pH valance , which is around 5 . 
     In every text book at first they discuss about skin physiology , pH of diffrent organs . And after every formulation they mentioned pH range in text books . If pH was not important we need not to study skin physiology . 
    In case of shampoo high pH may cause of hair loss . 
    It is new to me that pH ranges in skin care products are  ' arbitrary ' numbers .

    @Aziz - You may have misunderstood me.  The arbitrary numbers are the specific decimal points that you've listed.

    For example, you say a facial wash needs to have a pH of 4.5 - 5.5 but a hand wash should be 4.4 - 5.8.  There is no way you could possibly tell a performance difference if someone formulated a facial wash with a pH of 5.5 and another with a pH of 5.8 even though the claimed range is 4.5 - 5.5. These ranges are just rough guides. Not meant to be taken literally.  

    I agree you could probably tell a difference between a hand was at pH 8 and pH 5 (although I doubt most consumers would notice). 

    When you wash your hands you remove 92% of the resident bacteria so the pH doesn't matter that much as far as the microbes go. See this study. https://www.dropbox.com/s/5zqzfjsbrf30hst/hand-washing.pdf?dl=0

    Here's a paper that shows commercial shampoos range in pH from 3.0 - 9.0.
    https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4158629/  Claiming that it needs to have a range of 5.5 - 6.2 is not reflective of what the cosmetic industry is doing. It is just an arbitrary range written down by whoever wrote the textbook. It is not based on any science. If someone make a shampoo with a pH of 5.0, that's perfectly fine.

    Just because people write things down in text books doesn't mean those things are necessarily true or based on science. Most of the specific research on these things hasn't been done. The pH ranges you see for products should only be thought of as useful guides. They are not scientifically validated. 

    Yes, it makes sense to keep cleansing products at a pH range of 4 - 6 (depending on the system) but anything more specific is mostly a fairy tale.
  • Guys, if looking at it practically, as Perry said, generally speaking there is no difference. A 15% active matter SLES/CAPB mixture with a pH anywhere around 7 can be used for everything.

    However, from a consumer point of view: people who got used to using soap on their hands like the squeaky clean feel. It means, that adding quaternary compounds to a hand soap is kind of a waste.

    Exactly the same formula with a small amount of, say Polyquaternium 7, though will make a nice shower gel. A good shampoo will need even more cationics for a "conditioned feel". A face wash would not need any cationics, because they tend to irritate eyes.

    I would also agree that a face wash is better when has less active matter (8-10% although depends on surfactants), a shampoo for everyday use is good at 15% (clarifying can be more). In my opinion shower gel can be 15% as well, but the hand soap can be higher (skin on our hands is thicker and gets more dirty).

    @ngarayeva001 it is just an idea and general guide line and also customers compliance and overall marketing strategy. 

    When you design a product you have to consider 1. customers problem, 
    2. Solutions 3. Product positioning and marketing strategy.  
       I am working with hand wash,  shower gel and face wash for a long time . 
    For face wash below 8 to 10 % is better.  Here pH is very important.  If it is not pH valanced and well formulated  after wash one may feel harsh and hardening (uncomfortable ) effect on face . After wash they want a smooth feeling even without applying any oil and cream .

    The purpose of a hand wash gel is to remove mainly oil and fat and carbohydrate  after meal . In our region we take oily and fatty food. They also want smooth feeling and quickly removing of sleepery effect . 
    I use PQ 7 at . 001% . Higher usage feel a coat on hand . 
    I do a blind study with some sensitive skin and brand users. My finding is pH above 6 is unpleasant for hand wash with sensitive person or skin (?) . Also Some guys can't differenciate between hand dish wash and hand wash . 
    In case of hand wash 12 to 15 % active is enough.  
    In our region a 250 ml hand wash is nearly  $1 . 
    A 750 ml shower gel is above #8 . 
    So it is also a marketing strategy as well as customers demand to formulate a shower gel diffrently. From a shower gel customers want good foaming , sleepery effect a very good pleasent scent where as in a hand wash it is necessary to ensure odour neutralizing scent . 

    @Perry We all know that they are basically same,  though we make differently for business.  
    I personally use all four of them for any purpose when I required it .

    @Aziz here i had to use some sles based shampoo to do the dishes :-) luckily only until the next day and could make some old fashioned dishwash liquid.

    " After wash they want a smooth feeling even without applying any oil and cream " I heard that comment many times. I am not aware of a single commercial product that delivers on that "moisturising" claim and does actually cleanse to be honest. 

    When it comes to a face wash, it's easy for me "Can I lather my entire face and open my eyes for more than 10 seconds?". If the answer is yes I consider it mild enough for me.
  • AzizAziz Member
    I didn't mean moisturising,  I mean non irritating and no unwanted feeling on face after wash . 
  • How can we remove slippery and sticky feel after washing with face wash or hand wash its a big problem for me
    i wash my face many time to remove face wash from face

    If it's caused by a quat, your best option is alcohol or acetone ;) . Sorry for being a bit sarcastic but quats stick tightly to your skin and even as a molecularly thin film will feel slippery. Removing such trace amounts isn't easy and your best bet is to use a product which doesn't contain anything quat-related. Even some fatty alcohols and non-ionic detergents have this effect, though less pronounced. It's a bit like a rinse aid in dishwasher detergents which ultimately stick to the dishes; super annoying if doing precision lab work. Rinsing with a solvent is the only feasible option other than using detergents free of such rinse aids in the first place.
  • i m not using any quat i have used these ingredients 
    SLES (N70)
    CAPB 30%
    Sodium lauryl sarcosinate
    CDEA
    Glycerine
