@cjames No, they are two different ingredients. Unlike Guar gum, Cationic guar has a positive charge that confers it conditioning properties.

Hi May I ask is  Cationic Guar gum the same as Guar gum .I am in the UK and can not find  Cationic Guar gum. I have a formula the requires  Cationic Guar gum could I use Guar gum .Thank you 

Cationic guar gum has different types. The least expensive is called guar Hydroxypropyltrimonium Chloride. Search for that.

@Abdullah @ketchito you gave a alternative to guar gum but what is the solution with guar gum only, is there no solution?

What is the maximum usage rate of sodium laureth sulfate allowed in leave on and rinse off products? 

@Abdullah, Is sles leaving on skin considered good as it is a surfactant? I can’t answer your question but please clear your question me to understand something.

[drjaysee]

@chemicalmatt what are the beads? Why you are using it?

Perry said:

@drjayseesunish - well, I wouldn’t agree that if soap leaves a smooth silky feel that it’s only because of the oil. Dove has no oil in it. https://www.target.com/p/dove-white-moisturizing-beauty-bar-soap/-/A-84780837?preselect=11012602#lnk=sametab

It also contains almost no “soap” and is made up of primarily synthetic surfactants like sodium isoethionate, cocamidopropyl betaine, etc. The better feeling skin is based on the fact that it doesn’t feel drying to skin like a true soap. Those surfactants just feel better on the skin plus they are a little harder to rinse off than other surfactants. 

@Perry thanks for teaching some new things. I have read  that more TFM in a soap, having more mostiourizing  properties so TFM directly indicates the presence of more oil in a soap. I have seen many soap recipes that showing incorporating various  kinds of oil in  soap having  more moisturizing properties. If it’s not true then why people using different kinds of oil rather then using very cheap oil like palm oil? And one more thing, price of  this kind of soap is very high, that also relate to price of oil,  please clear my doubts..

True soap-based shampoos were replaced by synthetic surfactant-based products in the 1930’s.  

@PhilGeis thanks

Perry said:

First, soap is a surfactant, so when you make a soap-based shampoo you are making a surfactant shampoo. It’s a saponified fatty acid surfactant.

Next, soap, Castile or otherwise, is old technology. The first shampoos were made using it but there is a reason it has been replaced by superior synthetic surfactants. Modern surfactants just work better. And they don’t sting your eyes. A soap based shampoo is just terrible in terms of performance.

If you want conditioning, you get that from a conditioner. Delivering conditioning from a shampoo is inefficient and always inferior to using a conditioner after shampooing. 

Forget using soap for a shampoo. It’s like replacing all your light bulbs with candles.

@Perry Thanks a lot Perry to clear the picture. You are the Gem of knowledge. One more thing to know about the conditioner as in soap making oil is using in oil phase and we can see Dove or any other soap, they left very smooth skin feeling after it’s application so, if soap leaves such silky smooth feeling that is only because of oil then, why shampoo doesn’t give the same effect as chemistry is the same  for anything.

If just for yourself…you could shake vigorously before each use.  Think salad dressing.

@Perry  Thanks Perry  for your explanation with fantastic example. Now I am much clear about it.

[drjaysee]

@Perry thanks a lot for your answer. 
Today whole world going behind the word NATURAL. If alovera gel giving some advantageous effects then other herbs also release their properties through any medium. Here I came to know, natural is nothing except a word only. This is a marketing style. Pardon me if I  am wrong. Please explain why we are unable to use natural thing for making cosmetic things?

I have made a saffron gel, during making it, my questions are:

1. I lowered its PH up to 3, but do not know a suitable ingredient to increase ph apart from Baking soda( not prefer),TEA. Any other??
2. Final product is not looking glossy, transparent like a clear gel, looks as coagulation of any starch.
3. can we add Vit D oil?

Ingredients: 
Aqeuous solution of saffron
citric acid
TEA
Carober 940

Please have a look upon it..

Sorry, vit E

Gunther said:

Check to see what ingredient makes its pH so alkaline,
because when neutralizing it, it’ll form a salt and salts often leave powdery or whitish residues.

Glucosides leave little residues compared to other surfactants, especially the anionics like SLS/SLES.
Glucosides may fit in the “natural” narrative.

If your local VOC regulations allow it, you can add some alcohol as a degreaser. It doesn’t leave any residue and it might be labeled 

@Gunther . As you say it becomes salt then will the ingredients, lose their cleaning properties at PH 7?
So there is no meaning of any cleaning products having ph 7. So what should do then?

[drjaysee]

Ok, thanks to clear things.

@Microformulation, thanks a lot. 
One more thing,Is it possible to ask from existing members here? Like If I want to approach you for any solution, Is it ok? If yes, then how to approach you?

[drjaysee]

@pharma thanks for math

Abdullah said:

DMDM hydantoin and CMI MI is good for cleaning products

Ok, should we use both in combination or alone is sufficient. What is recommended % in product?

drjayseesunish said:

Preservative? 

Hi! Yes, you should have a broad-spectrum preservative in products which contain (or will be interacting with) water, because water is a source of life and a good ground for bacteria and mold.

drjayseesunish said:

Why we need to preservative because these all are chemicals?

Even more - everything in our life is chemicals. Why? Because bacteria and mold are so stubborn, so they can live and growth in almost any cosmetic product.

drjayseesunish said:

Is phenoxyethanol at 1%  good?

Again, I am not a chemist, but I think just phenoxyethanol is not enough, since most of commercial products tend to not use it solely. Also, preservative choice depends on many factors - how long shelf life should be? should it be “organic” or “natural”? What is pH of your product? etc.
  

Informative!  Thanks. 
I want to know some broad spectrum preservative that can be used in any wash and cosmetic products.
I think you are saying a kind if combo of different preservative of particular purpose. 
If anyone can share your knowledge, please..

Like any field, studying book is good but by taking a course you can learn better and easier. 

Absolutely right

@drjayseesunish You could start with this book: https://www.amazon.com/Liquid-Detergents-Surfactant-Science-2005-08-23/dp/B01A1M5CE0.

This is unavailable dear, any other source if you know. 

You can check for this book in Genesis Library. 

Thanks a lot dear!

Pharma said:

THIS resource is worth gold (it’s been written by a professor and fellow of the Royal Society of Chemistry, links theory and practive, it’s interactive, and best of all, it’s free too).

Thanks a lot! Your great help!

Fekher said:

@drjayseesunish YouTube is very important start point then you should watch  and watch for each product then try to practise and improve your product.
  Also chemistscorner is amazing place to learn about detergent. 

Right, and yes chemistcorner is fantastic!

This much PH will  remove all germs n dust particles along with skin also.
