Shampoo too thin… can I thicken after it’s done?
Hello… I have purchased a shampoo base that I love but it is a little too thin. Everything else about it is great, and I don’t want to return it. Can I just thicken it somehow?

conduct a salt curve at 0.25 to 1% and choose viscosity you need/want.
-
I agree with @”DRBOB@VERDIENT.BIZ” - But it would also help if you posted the ingredients in the base.

I did read this article (https://chemistscorner.com/salt-curve-analysis-how-to-control-cleansing-cosmetics/) about the salt curve and am happy to try that. However, is there another item that could be a little more nourishing? This particular shampoo (and sadly, I don’t have the formula) is designed for and works great on dry, damaged, color-treated hair. I don’t want to impede that. It contains amino acids. Some thickeners I’m considering:
Salt, (would this just be table salt?)
Kaolin clay
Xanthan gum
any other recommendations??
If I get it to be the viscosity that I want, I can order future batches with the custom edits. -
Salt will not affect the performance of the shampoo. No thickener will increase the “nourishing” of a shampoo.
The clays and gums may be difficult to incorporate into a finished shampoo base but you can try it. Also, something like Hydroxpropylmethylcellulose or Hydroxyethylcellulose can be used as a thickener.However, usually the thickener is added right after the water during production (second or third ingredient). Post adding a thickener isn’t always feasible.

Salt as sodium chloride is table salt which will not interfere with your dry/damaged color Variant but you should get ingredients as you will need them for label.

Here are the ingredients. I also want to remove the cocamide dea from the next batch as well, so since I’ll be changing it anyway, I wanted to address the viscosity as well.
Ingredients: Aqua (Deionized Water), Ammonium Laureth Sulfate, Ammonium Lauryl Sulfate, Cocamidopropyl Betaine, Cocamide Dea, Triticum Vulgare Germ Oil (Wheat Germ Oil), Glycerin (Kosher, Vegetable), Prunus Amygdalus Dulcis Oil (Sweet Almond Oil), Prunus Armeniaca Kernel Oil (Apricot Kernel Oil), Simmondsia Chinensis Seed Oil (Organic Jojoba Oil), Aloe Barbadensis Leaf Juice (Organic Aloe), Panthenol (Vitamin B5), Silk Protein Amino Acid Blend of Sodium Pca, Sodium Lactate, Arginine, Aspartic Acid, Glycine, Alanine, Serine, Valine, Isoleucine, Proline, Threonine, Histidine, Phenylalanine, Asparagus Racemosus Root Extract (Organic Shatavari), Coriandrum Sativum Leaf Extract (Organic Cilantro), Geranium Maculatum Extract (Wild Geranium), Chamomilla Recutita Extract (Chamomile), Rosmarinus Officinalis Extract (Organic Rosemary), Centella Asiatica Extract (Organic Gotu Kola), Equisetum Arvense Extract (Horsetail), Taraxacum Officinale Extract (Organic Dandelion), Potassium Sorbate, Sodium Benzoate, Phenoxyethanol, Alcohol, Ethylhexylglycerin.

The salt should work fine with or w/o Coconut DEA so just do a salt curve.You may have to increase salt slightly after removal for next batch.
-
I will try the salt curve. Thank you for answering so quickly! You guys are awesome!
-
No salt is listed in the original LOI so I suspect that the CAPB was used to adjust viscosity. It’s cheap enough so you could simply add more.
-
Too expensive as high ratios or CAPB/Anionics are required usually between two-three to one.Salt is hard to beat.
-
If you want to remove the Cocamide DEA, you can replace it with Coco Betaine (different from Cocamidopropyl Betaine) which should help with your thickening.

Myristyl Lactate? NaCl would be the cheapest solution.
Isn’t the shampoo irritant? ALS seems to be in a high concentration.
Not sure about the huge list of oils, most likely will not do much thing. -
What about liquid Crothix? It is intended to be added to the finished product and claims to be an “irritantcy mitigator”
