Filling machine suggestion for thick butter?

thinking123 — Tue, 15 May 2012 03:00:12 -0400

I am wondering if anyone knows of a machine for small home based production that can fill narrow containers with thick buttery products. A manual or electric machine, piston perhaps but something that can draw up thick, (like petroleum jelly thick) product and press the product out. I am looking for the smallest machine possible.
Thanks!

A Chemical Free Anti Aging Cosmetic?

thejoggler — Wed, 16 May 2012 22:08:42 -0400

Chemical free claims always bug me. You see them a lot in the sunscreen market where people claim “chemical free sunscreens.” For some reason they don’t see titanium dioxide or zinc oxide as chemicals. But they are chemicals! Every substance is a chemical. Chemical free anti aging cosmetic So, how is it that this headline [...]

ph for AHA lotion

itunu — Thu, 17 May 2012 06:04:42 -0400

I would like to include fruit acids in a lotion http://www.lotioncrafter.com/fruit-acid-complex.html - would these fruit acids be effective if the ph is 5 or 6?

Also, if I were to use lactic acid in a lotion http://www.lotioncrafter.com/lactic-acid-88.html instead of the fruit acids would a ph at 5 or 6 be effective too or does it need to be a lower ph?

I would also like to include niacinamide http://www.lotioncrafter.com/vitamin-b3-niacinamide-usp.html in that same AHA lotion but from what I read niacinamide prefers a more neutral ph - could I get away with ph of 5 or 6 and the niacinamide still be effective?

Turnkey Solutions

Microformulations — Thu, 17 May 2012 04:20:31 -0400

I am doing a large project for a client. On some of their products a "turnkey" product will be most feasible. Does anyone have any experience or suggestions in sourcing these turnkey solutions out? I would like to find the most economical source, but also have a healthy selection to choose from.

Transparent "soapy surfactants"

pma — Wed, 16 May 2012 00:43:52 -0400

Sorry if my question is stupid, I'm not a chemist, but I like to give ideas for the chemistry who works for me and to know more about formulations.

What "soapy surfactants" can be transparent? I know lauric acid and myristic acid due the fact this liquid soap from LG contains these surfactants and is totally transparent:

Water, camellia sinensis (green tea) extract, lauric acid, myristic acid, disodium cocoamphodiacetate, potassium hydroxide, cocamide dea, glycerin, potassium chloride, portulaca oleracea extract, butylene glycol, magnolia bark extract, white willow bark extract, citrus grandis (grapefruit) fruit extract, propolis extract, thujopsis dolabrata branch extract, anthemis nobilis (chamomile) flower extract, brassica oleracea (broccoli) extract, panthenol, caprylyl glycol, tetrasodium EDTA, 1,2 Hexanediol, fragrance.

More options? I'd like a transparent liquid soap with these "soapy" surfactants (you know, consumers love foam, and there's nothing so great for foam like these "soapy surfacntes", because they foam up like a shaving foam, very creamy and abundant).

Another question: are they more expensive than SLS/SLES? I only know lauric acid can be a bit unpleasant to formulate...

hydrous Benzoyl Peroxide USP

kfox — Tue, 15 May 2012 00:33:09 -0400

Hello,
used to purchase BP from Spectrum Chemical but now going to buy from Sigma. How do I know I am getting the same BP?

This is the one I got from Spectrum......... https://www.spectrumchemical.com/OA_HTML/ibeCCtpItmDspRte.jsp?a=b&minisite=10020&respid=50577&item=1&itemGrpNum=BE156&isSupply=0 ;

MSDS section 2 says BP is 75% and water is 25-26%

Which one do I get from Sigma?................ http://www.sigmaaldrich.com/catalog/search?interface=Product Name&term=Benzoyl+peroxide&lang=en&region=US&focus=product&N=220003048+219853269+219853286&mode=mode matchpartialmax

And Luperox A 75 kind of says the same thing in description but that would be my guess. not for sure though

Formulating lotion/cream with copper peptides

itunu — Wed, 16 May 2012 16:02:35 -0400

I would like to incorporate copper peptides into my usual cream/lotion and would appreciate your advice on this. I haven't formulated before with this ingredient and can't find much on the web.

(GHK-Cu - INCI: Copper tripeptide-1 from http://stores.skinessentialactives.com/-strse-139/Copper-Petides,-GHK-dsh-Cu-2/Detail.bok)

What % would you recommend I use - I read 0.5% and 10% so am unsure. Presumably I add at cool down.

So I'm thinking would this work (this is my formula cream for dry skin):

WATER PHASE

%water,

0.2% xanthan

4% Niacinamide,

10% hydrosol,

10% aloe vera concentrate,

3% sodium lactate,

5 glycerin,

5 ethoxydiglycol

0.1 edta.

0.5% allantoin

OIL PHASE

12 cocoa butter/shea/cupuaca butter or petrolatum (presumably I can buy some vaseline and add it?)

4% C12-15 akyl benzoate or coco-caprylate,

4% avocado/rice bran oils,

6% apricot/FCO/Meadowfoam oils,

3.5% glyceryl stearate with either cetearyl glucoside or peg100 stearate

2% Oliwax LC - Cetyl Palmitate (and) Sorbitan Palmitate (and) Sorbitan Olivate

2% cetyl alcohol/behenyl alcohol,

COOL DOWN

5% multifruit BSC (fruit acids),

0.5 liquid germall plus (Propylene Glycol (and) Diazolidinyl Urea (and) Iodopropynyl Butylcarbamate),

1 tocopherol,

3 d-panthenol,

4 dimethicone 1000 c.s.,

2 cyclomethicone,

2.5% of 1% solution of hyaluronic acid (the other 99% is water),

3.5 hydrolyzed oat protein,

1% lavender essential oil or lemon essential oil or fragrance oil

2% retinyl palmitate (Contains 1 million IU per 1ml in fractionated coconut oil)

and also copper peptides at XXX%.

Just realised that's a lot of ingredients!!

Are there ingredients which I should not include in my cream like AHAs, niacinamide etc?

Also will niacinamide be OK in a ph of 5 as I'm thinking the fruit acids will reduce the ph? (presumably the fruit acids will still work in ph5 and don't need to be lower than that)?

Oil from supplier vs. oil from the grocery store?

thinking123 — Wed, 16 May 2012 13:50:05 -0400

I need safflower oil and/or olive oil for a massage cream recipe. I am looking at purchasing the oil(s) in gallons per month. With this new needed increased quantity, I am looking at oils from cosmetic suppliers and the prices are between $34 and $50 a gallon. When I look in the grocery store, I see safflower oil for about $18 a gallon and $20 a gallon for olive oil. Is there something about cooking oils in the grocery store (specifically olive oil and safflower oil), that I should avoid for a cream recipe? Additional Information: I am about to start producing 8 gallons per month, all of the 8 gallons are used up within the month it is produced.
Thank you.

New interesting cleanser from Kao

pma — Sun, 13 May 2012 17:26:55 -0400

Kao has launched a interesting cleanser in Japan. I'm trying it and this cleanser really makes the foam the video is showing:

http://www.youtube.com/watch?feature=player_embedded&v=hqBUZUZIzOg

http://www.youtube.com/watch?feature=player_embedded&v=KGmnLfX_EMk

Ingredients: Water, Laureth-4 Carboxylic Acid, Glycerin, Palmitic Acid, Lauryl Hydroxysultaine, Potassium Hydroxide, Stearic Acid, Myristic Acid, Ethylhexylglycerin, Ginger Extract, Betaine, Butylene Glycol, Polyquaternium-7, Titanium Dioxide, PEG-6, Disodium EDTA, Frgrance.

For my surprise, it doesn't seem dry out the skin. At least not more than a "conventional" cleanser.

I think this formula could inspire who wants a "sulfate free" formula with A LOT of foam.

I guess the 1% is KOH...

hydrogen peroxide and calcium hydroxide

Deionized Water

Microformulations — Thu, 10 May 2012 15:35:09 -0400

Of course in every Formulation that I do, I use deionized water and not tap water.

However, one of my smaller accounts does not have a water system. I learned this after a natural product began to discolor. I am not sure that the water is the issue, but as I walked through the probable causes, I said "You are using deionized water, right?" Well, come to find out that they were using water from the city water system. Needless to say I was a bit concerned.

They were told several years ago by their old Plant manager that city water was fine as long as you heated it to 80C first. I explained all my concerns regarding ions and bacteria. Here in the South we have a high level of Pseudomonas in our water levels. I have been told that this is an issue common south of the Mason Dixon line due to the lack of sustained freeze conditions in the water table.

Well I am sympathetic since I don't own a water system yet and I buy mine by the carboy. Is there a way to buy deionized water from a local supplier in larger quantities than a 5 gallon carboy? I had once heard of a plant buying it by the tankful on a mini-trailer. Has anybody dealt with this or alternatively an inexpensive way I can get them into compliance?

Toothpaste

Microformulations — Tue, 15 May 2012 13:12:20 -0400

I have had a client approach me in regards to a very ambitious private label line. All the products are in my comfort range with the exception of a toothpaste. Long ago I learned that wisdom is really knowing what you do not know. Taking this to the next step is identifying what products you can and should make. Toothpaste is not one of mine.

I still need to talk further with the client, but if all falls in place, is there anyone comfortable with formulating and manufacturing (or alternately outsourcing the production) of this product? If so, email me at markfuller@microformulation.com

Ammonium lauryl/laureth sulfate

pma — Thu, 10 May 2012 08:11:18 -0400

Some companies prefer to use ammonium lauryl/laureth sulfate instead of sodium lauryl/laureth sulfate.

Is there any special reason to do it?

How haircoloring ingredients work?

dajahair — Sun, 13 May 2012 14:53:51 -0400

I'm a haircolorist. I would like to learn more on how haircolor works and its ingredients. What we are taught and what actually happends differ so much. I know the basic theory. Does anyone recommend any books or courses to help me understand them? Why do cool pigments oxidize faster then warm ones? How come the cool pigments over deposit on porous hair? These are some of the questions I would like to answer.

Thickened Liquid Dishwash (Low Viscous Liquid Dishwash)

iykecicero — Mon, 07 May 2012 11:56:57 -0400

Fellow chemists,

I have been trying to formulate thickened liquid dishwashing detergent without success. I am afraid I could oversalt the formulation with NaCl. I am also constrained by dearth of specialty rheology modifying chemicals as I operate in a developing country. However, I am considering using Ashland's Natrosol which is available. But I do not know the result.

I am also intending to make a clear viscous liquid that would be filled in PET bottles. I have encountered situations where there were separation of the liquid after some days. I had to use propylene glycol for proper emulsification. However, it crashed the viscosity. I need your expert advice on this. Below are my ingredients. Any improvement on it would be greatly appreciated.

a) Water - 75, (b) Sulphonic Acid 96% active - 15, (c) NaOH - 1.95, (d) Cocamidopropyl Betaine - 1.2, (e) SLES 70% Active - 3, (f) Cocamido Diethylene Amine - 1.6, (g) Versene - 0.2, (i) STPP - 0.5, (j) Sodium Sulphate - 0.5

Matrixyl 3000

gaylene — Thu, 10 May 2012 17:54:35 -0400

Can anyone please help me with this peptide?

No one seems to know the percentage in the Matrixyl 3000 itself. I have spoken to suppliers and they cannot tell me how much of the matrixyl 3000 is actually pure Matrixyl. One supplier said when you purchase matrixyl 3000 it is at 3%. When I look at product online claiming that there serum is 25% Matrixyl 3000, is this 3% Matrixyl 3000 added at 25%. I am totally confused. If anyone has any knowledge or ideas about this I would be grateful?
