The only use for vinegar in a shampoo is when the shampoo is common soap and the hair as a result is clagged up in hard water deposits. Vinegar is used as a rinse. This was the way before surfactants were invented. Get rid of it. Besides, it stinks.

[belassi]

Just use Quikpearl. Excellent.

Instead of Lamesoft try Polyquart H-81 it gives the hair ‘bounce’. Use rate 1% typically.

[belassi]

0.5% is five times too much peppermint oil.

[belassi]

In my experience Lamesoft PO65 is short flow and will not give the effect you are looking for. Also it makes the hair soft, alright… horribly limp in fact.

[belassi]

Iselux is not for your application. I tried it and decided that it was too expensive by far.

[belassi]

I already did.

[belassi]

I refuse to get involved in skin whitening creams, especially in Africa.

[belassi]

I doubt this will work as-is. The only emulsifier is the TEA soap.

I should think that she will be able to get red palm oil locally. With sodium hydroxide that can be made into soap. Hair clients, I’d make a basic shampoo with SLES/CAPB/CDEA, pH adjusted with citric acid, peservatives are needed in such a small percentage that post could be the answer for those. If there is a bottling plant for soft drinks anywhere near, she could probably obtain sodium benzoate and citric acid there. However there are other possibilities too. Olabisi Glow (see Facebook) in Nigeria does things like “yoni steaming” and her business, Glitz ‘n Glow, seems to be doing well. I’m currently advising another member of this group on beginning a new brand, he’s in Nigeria.

A patch test study found “An increase in the use of DMDM hydantoin in cosmetic products will also inevitably increase the risk of cosmetic dermatitis in consumers allergic to formaldehyde.”

And the devil’s preservatives are in it:
Methylchloroisothiazolinone
Methylisothiazolinone

[belassi]

Look at the preservatives in it.

The Dermatologist has quite a lot to say on this topic. I am getting good results from my Facebook campaign.

Anyone still using Kathon CG should read this:
In 1988, de Groot and colleagues18 reported on the significant ingredients responsible for allergy to cosmetics. In the 119 patients with cosmetic-related contact dermatitis, 56.3% were associated with skincare products. They also found that preservatives were most frequently implicated (32.0%), followed by fragrances (26.5%) and emulsifiers (14.3%). The most significant cosmetic allergen was Kathon CG, (a preservative system containing, as active ingredients, a mixture of MCI and MI) reacting in 33 patients (27.7%).18 Within 6 months de Groot and Herxheimer19 published another study on a significant number of the cases of Kathon CG (MCI/MI) allergy caused by products of the “leave-on” variety (eg, moisturizing creams) and stated that an epidemic had begun.

Thank you!

CBD. Just wave some weed gently over the mixture. It will have the same effect (none).

[belassi]

I’ve begun my campaign against these preservatives and it seems to be hitting a nerve. Since it is a page, I can boost my posts. For each $10 I am getting 2,000 impressions. At the moment I am just targeting Mexico.

[belassi]

Possibly the preservative.

[belassi]

is there a way to increase the spreading ability
Sensorials depend mainly on two factors. The surfactant and the thickener. You will have to experiment.

[belassi]

Since this is a simple formula you could just adjust the pH to 5.0 and use sodium benzoate at 0.4%. Methyl paraben is usually combined with propyl paraben, typically at 0.3% + 0.15%.
This is the best thickener but it’s not cheap. Gums give an unpleasant sensorial.

[belassi]

Just don’t expect any actual effect.

[belassi]

how do I know how much percentage of each chemical I have to use after reading the ingredients from the product labels?
  — This comes from knowing typical use amounts and assumptions about the accuracy of the label. EG if it’s a shampoo and I see “sodium benzoate” I’d expect to see 0.1 to 0.5% usage, depending on inclusion of other preservatives.
Your second question, if you increase the percentage of an ingredient the formula is simply recalculated, typically I use Excel for that.

[belassi]

They don’t heed customer complaints, I see no other way. Give me another ten minutes and I will have set up a new group against them, on Facebook. I am pretty good at getting a lot of hits with my boosted posts.

[belassi]

Decyl glucoside is terrible. Please understand, shampoo design is not easy nor intuitive. Unless you want to spend the next two years throwing surfactants down the drain, considering this is only for personal use, it will cost far less to find a commercial product that you like.

[belassi]

I can imagine a market in which it replaces tallow. However, tallow is so cheap that I can’t imagine being able to compete with it. Not in the soap industry. I can’t see any use for my designs. I have no use for animal type fats, I use combinations of vegetable or nut oils, and artificial, designed, esters.
