Thanks everyone   Im not at all familiar with dyes etc, but obviously what I need is a dye instead of a pigment.  I have since tried several direct dyes and they will suffice with some formula modification.

Priya,  I understand that tacky/sticky feeling from your formulation you talked about… Can I suggest, maybe keep the grade of Petroleum Jelly you have, add something simple like capric/caprylic triglicerides or C 12-15 Alky Benzoate and THEN thicken with a wax…  I am not a chemist, but have made a lot of anhydrous product experiments and this is a way I use to cut out that awful claggy feel of straight petroleum jelly.

eg;  Zoological Institute (Hanover) - Dogs skin pH (Abdominal) ranged from 4.84 - 6.97, but under stress could be much higher (this could include bathing! LOL) Cats 5.4-6.7.

@David… wow thank you for that link!  This is a particular area of interest for me, and I’m always on the lookout for different papers/trials and findings  
Different results from other studies but these are veterinary based (Colorado St Uni), obviously lots more to look into!
Thanks again!

@ Belassi … I made the base mix as above, I used (Sensient) a pigment dispersion in Isododecane (Carbon Black/oxide) and it settles within 6 hrs.

no water here other than in the Ethanol (97.5%).

do you have any ideas?

[hishine1]

Thanks for those links Bobzchemist

Would these colours still not precipitate to the bottom of my bottle?  I need to keep the formula super simple for cost. Quick dry hence the Ethanol (50%), Cyclo with 3% Dimethiconol/Cyclo for a little gloss.  Ideal would be to package into clear bottles.  Any other additives I should be using?

Neutral pH is paramount. The pH of animals skin (fur covered mammals) is generally a lot lower than human skin, and varies from breed to breed also. Domestic pets are also prone to all sorts of dermatitis so the more mild surfactants you can use the better.

Thanks guys.

Difficult for me to describe the exact product, but a basic color enhancing spray shine.  I need hi gloss, much like a volatile silicone hair glosser, which is why the high oil content. I should have said ester/silicone perhaps as the oil content.

@Bobzchemist yes, VOC restricted. I’m just looking at a microsprayer atm. 

It could well be a liquid spray, but as a gel would be novel and also I thought it may be more economical. Not able to find a similar starting formulation so I’m behind the 8 ball already.

[hishine1]

Thank you Bobzchemist!

HI, back again!  Ok, so I have a tin of stuff here… acetone, resin, pigment are the only listed ingredients. It is water thin and black.  I’m guessing it is some sort of wood stain essentially but used on nails (as in fingernails!)  I would like to make something similar/economical but a little more nail friendly.  This product goes on with a brush and dries in about 30 seconds leaving a hard and extremely glossy film.

Would this be similar to your base Nasrins?

I dont think I would need the Nitrocellulose? 

[hishine1]

ah brilliant. Thanks milliachemist!  

[hishine1]

Editing to add…

I need a THIN (low viscosity) ultra gloss, super fast drying top coat (clear) and same that can hold a pigment (black).  

So many conflicting ingredients I am searching… any directions would be helpful. Thanks

[hishine1]

@ Bobzchemist LOL thanks for that…. arrrgghhh I already did!  I have a kg of Indopol H100 and of course I spilt some 😮  I am using Iso Alcohol to cleanup, I have a lovely shiny wood floor though…

How would the H1900 go with polyamides?  I am waiting on samples of those so wondering if I should order the H1900?  I only have one grade of polyamide atm also. I’m trying to achieve a ‘hard’ gel… not quite a stick but not a fluid gel either. Hard for me to explain without the tech knowledge sorry.

Is the product you need or something similar already manufactured?  Maybe start with contacting the manufacturer that makes a similar type of product and see if they will work on it with you. 

Reverse engineering is what you are after if you contact a formulator or chemist to get a basic idea of what is in the similar product, and then you will have to employ a formulator in that field to produce a formulation that may be better or more suited to your needs.  Big $$$.  Its important to be realistic and weigh up the cost of producing a novel product versus what you may actually make from it. 99% of the time it is a money pit unless you are literally revolutionising (sp?) something.

I’m not a chemist either…. but there are some extremely knowledgeable and qualified people on this forum (and the owner!) so read carefully their advice.  I have read nearly every thread and post here to increase my knowledge… and knowledge will enable you to further you goals

good luck with your search

[hishine1]

Thanks guys… will check them out.  

I’m not looking to replace it entirely… just halve it in a lipgloss type formula. It (CO) can sometimes be an irritant in high amounts, I patch tested on my arm for a day and it did irritate after excersise.  On a much lower skin pH I wonder if too much natural CO will irritate the skin.

Hi all. Thought I should give an update for anyone looking at previous posts for Oil Thickeners. I havent yet finished all formulations as there are still several ingredients to try.
But most successful so far (for my purposes) has been using a combo mix of Polyamides with a solvent and vegetable oils or hydrocarbons and or silicones. I have read elsewhere that these give a rather stiff/crumbly and not so elegant clear gel/stick, but loaded up with organo silicones it gave me a lovely feel with the clarity and structure close to what I need.

Thanks everyone for your input and comments! very helpful and appreciated

[hishine1]

over here…. where are you located Belassi?

[hishine1]

Apologies for being so tardy! Overrun with work and little people.

Sorry - its a terrible Australian (I just deleted Ozzy) habit to abbreviate everything, or alternately ad an O or EY so it sounds good when we yell it I did mean Non-ionic Emulsifiers. Its just a basic anhydrous bath oil formula, I should have said blooming bath oil maybe.
Without the chemistry background (me) it is hard to choose - there are just so many emulsifiers to use, I could just throw some detergent in and it will make a blooming oil, but I’ve got some suggestions now and have ordered some samples.

I’ll try to be more specific with my next question… about silicones. I’ll put that in another thread. Thanks very much again!

[hishine1]

going to add…. prefer non rheology modifiers.

Hi mikebavington

From a consumer point of view I would stick with well known names… I have been flicked to small dodgey cart sites for various products and I’m put off about placing orders there.  I have recently changed to Shopify, easy, cheap, lots free stuff and a few customer comments have been that the process is very quick and they felt more compelled to buy as it is a trusted site.
Just my obs.  Maybe an eBay store is an option?  Dont know if they have a fulfillment service though.

Hi!  Thanks for approving me to join this forum.  My name is Paula, from the west coast of Australia. I have no background in Chemistry, barely made it through a few yrs of high school actually, but have had a bit of interest in cosmetics and formulating for some time.  I run a successful business in the animal industry, producing hair and coat conditioning treatments, grooming products etc, all of the products I have designed, formulated and manufactured myself, and I am proud to say the business does extremely well…we start exporting internationally very soon - and I have never marketed or advertised my products. It’s been a ‘from the kitchen bench’ type experiment, to learning everything I can about ingredients and formulating.
I would like to expand and produce some novel hair care products for the ‘human’ market as well, so I hope to pick up some tips from the amazing chemist brains on this forum, I am happy to share any of my own experiences if they are of any help also.

Cheers
