Need some advice to formulating cat shampoo

i've been made one prototype of cat shampoo but it was made with 10% SLES, 10% CAPB, and 1.5% Cocamide DEA. But when i apply it for handwashing its foam is not rich, how to improve that? anyone of you ever make a cat shampoo? and i want to develop more formula but this time is sulphate free cat shampoo, i'm using decyl glucoside, CAPB, and SCI. Any suggest for thickener that cheaper than Acrylate copolymer?

Thanks in Advance.. ;)

    As far as I am concerned cats should not take baths, it is traumatic for them. They self clean as nature intended. On a few occasions when they have mishaps, I usually use a small amount of dog shampoo and minimize the cleaning only to the problem area. Other-times, I just do a dry cleaning with a slightly moist paper towel when it is just dirt. You should look up dog shampoo formulations on this website for guidance.

    @Biocade21 try xanthan gum I guess it can be useful for your system. 
  • You can just up your surfactant % for more foam, but also keep in mind that hair will foam a lot more than bare skin, so test it on hair/fur before writing it off completely.

    I've already formulated a product that was called "dry shampoo for cats", so it was powdered and aimed to absorb oil from the fur. Because cats groom themselves frequently, not all owners will agree to give them recurring baths (but there are plenty of liquid product benchmarks out there). As for the thickener, try something with xanthan gum as @Fekher suggested (:
  • @Lab Do yoi somehow manage to remove the dry shampoo from cat's skin after application? I'd be a bit worried that it stays there when theyvtend to lick themselves all the time.

    @Biocade21 For the sulfate SH, try playing around with the percentage, as someone else suggested...or include an amine oxide (lile Lauramine oxide).

    For the sulfate free, replace Decyl glucoside (hard to thicken) by alfa olefin sulfonate, and add also some Cocamide DEA like you did for the first one.

    @ketchito ;We formulated the base with Tapioca Pure to avoid ingestion problems, and it had no fragrance or surfactants. The concept is that you apply it to the feline while spreading it with your hands so that the formulation absorbs the oil and then removes it by rubbing your hands over the animal's body or combing it... From what I remember it was based on some market products that instructed in this way

    Very few cat breeds like water and those that do are not that common as pets.  As others have stated ... domestic cats self groom.  A cat shampoo is simply a bad idea.  Why subject the cat to the stress of water and the application of surfactants to their coat and skin?

  • I don't have any useful formulating advice, but the need for usable cat shampoo is real. Many cats don't need bathing, but there are some cats who won't or can't groom themselves. This is usually because we've bred them to have flat faces, often with very fluffy coats, or the cats who have no coat at all, and sometimes cats need bathing due to age or medical conditions.
    I recommend the cats playlist on The Girl With The Dogs (a professional pet groomer) YouTube channel for learning more about cat grooming and to enjoy some dry Canadian humour.

    @justaerin When cats have hair problems they need to be brushed. I agree some obese cats and some with medical conditions may need help with wiping they backsides, but those are exceptions. Bathing a cat can cause anxiety in the animal and be damaging to his or her emotional health. As a Canadian cat lady I know from experience. Just washing the backside of my cat when she had poop all over was traumatic, she was angry with me for 2 days after that isolated incident.
