Moisturizing effect in Dove after washing

Hello all,

I have noticed that Dove soap leaves a moisturizing effect on the skin after taking bath.

It feels like smooth oil/lotion is still left on the skin & it will not go in spite of using much water. Is it due to glycerin Or Sodium stearate?

Can anyone please guide on which ingredient or chemical can provide this effect?

    It's probably the sodium tallowate, which in simpler words is soap made by boiling beef fats with lye. It's remarkable how many veggies, vegans etc will happily use Dove soap.

    That's because the cattle that provide the beef fats are grass fed, free-range cattle.

    @MarkBroussard And the tallow is extracted through painless liposuction?

    Yes, and the cows all have names and roam happily in lush, verdant fields full of hopping bunnies, butterflies floating in the breeze and they only drink from glacier fed streams.  I heard that Dove was going to stamp the name of the cow that provided the tallow for each bar of artisan soap along with the artiste's hoof print on an authenticity tag.

    Well Dove is really really complicated stuff. I just can't imagine. It has several different solid and liquid synthetic surfactants. It has sodium tallowate, and also sodium cocoate from coconut oil. In fact it sounds to me as if someone took some standard fairly crude hot process soap and chucked in a lot of synthetics to radically improve its performance and shelf life and so on. Titanium dioxide is in there for whiteness. It has CAPB, LSI, all sorts.

    It is its neutral pH that leaves this effect and not the "squeaky" clean sense of the ordinary alkaline soaps.

    I will posit it is none of the above - though I do like the Marks' Elyssian fields touchy-feely cruelty-free vegan-safe scenario, once I've consumed the contents of my bong. Unilever is using encapsulated oils in that soap.  This uses that spherite dendritic surfactant thingy that Rhodia (now Solvay) came up with several years back. Pretty nifty: I made up a prototype that encapped 5% dimethicone inside a standard anionic-amphoteric system. Never did make a sale with it though. Guess you have to be Unilever..

    Way cool Matt. Thanks for the explain.

    What I find funny is that the elimination of animal products from cosmetics and most soaps has resulted in a massive increase in the amount of waste going into landfills and down the sewers. Not one animal has been spared - all the PETA and associated fanatics did is create much more environmental waste.

    I don't regret eliminating animal products from my designs. I once made soap using lard. It was disgusting, it had a piggy odour!

  • In India, they are having different formula. They are not adding Sodium tallowate & claiming Bathing bar means contains mild surfactants.

    what is the green point to  using tallow in soap formulations? cows are killed to obtain beef not for tallow. Now we have more waste to dispose in the world.

    We made a lard soap for a hunting lodge in Canada once. It was most unpleasant, bacon meets the barnyard smell. They were happy with the soap, oh well. That is the last time we used animal fat.  
  • animal fatty acid requires some refination process with salt and potasium alum to eliminate proteins and oxidized materials to remove residual odors.
  • @Dilfre: I am interested in the refining process to remove unpleasant odor from animal fat. We are looking at using small amounts of wild game lard in CP soap. Can you elaborate on the steps?
  • wild game lard? Elise, Do you really think you need it? there is a lot of waste lard almost free coming from sacrificed domestic pigs all around the country. 
  • BobzchemistBobzchemist Member, PCF student
    @Dilfre isn't kidding about the almost free part. Under certain circumstances, some places will even pay you to take it away.

  • They would be soaps to appeal to tourists of the Far North. So the wild game tallow is essentially the story line. "Bear and Honey", "Beaver and Birch", "Wild Moose"... you get the idea. 

    Although, I do see the potential for a waste lard project in my husband's rural Mexican hometown. Many small scale abattoirs and women in need of a sustainable craft industry. I think an environmentally conscious/fair trade/traditional craft spin may overcome the initial distaste for animal products. As long as they are aesthetically pleasing. 

    I might be encouraged to try it if I just knew how to handle the stench.

    Properly prepared and deodorized, lard is not hard to deal with.
    This, for example. Most people don't find it distasteful when they cook with it, or eat it, but cosmetic use is now taboo. There are a lot of soaps still made with it worldwide, but there are extra steps needed to refine and deodorize it, so it's easier all around to stick with vegetable oil. In a situation where labor is essentially free, however, it might work well.

  • Dove is a combo bar: part Soap and part Syndet. The reason they add the synthetic surfactants is to make it more gentle to the skin and have a lower pH than soap alone.  The Steric Acid in this bar is the "1/4 moisturizing cream" that they talk about, and responsible for that lasting feel. 
  • About the tallow/lard thing... I'm quite surprised by the comments above and wonder about the processing involved. I'm far from being an animal fat expert, I only ever had tallow from a UK based reseller:

    The quality was on par with coconut oil and palm oil. So I support the opinion that it can be a brilliant raw material if prepared correctly.
  • Hi Alicut
    Use of Stearic Acid without saponification or use postasium or sodium salt? thanks in advance.
