I read a number of articles including in BBC stating that homemade hand sanitizers are not effective. even if 99% alcohol is used, it will cause more harm to hands as commercial hand sanitizers contain emollients which protect the skins. Can anyone explain how to prepare an effective homemade...

Thanks. the link provided is much helpful.

thanks this is very helpful.

Hi, I've been making CPLS for some time. Although I have a basic recipe I do change it slightly every time to see how the new ingredient behaves. Every time I would end up making an oil blend and the lye solution as recommended by a soap calc. Every time when I wanted to try a new ingredient I...

I actually wanted to make smiley-faced soaps something like this :)

I had a similar experience when I added additional glycerine to the mix. in this case the super fat is unusually high. That may the one causing the issue.

Hi, Since last post, I have tried using HEC for thickening than salt. getting HEC to properly incorporate is a challenge, different forums suggest different approaches. after a few test cases, I finally managed to get it right. Now my soap doesn't suffer from issues which we face when using...

page 3 of the PDF Extraction of rice bran oil Oil of stabilized rice bran was extracted into hexanes using Soxhlet apparatus. The extraction was carried out on a water bath set at 50 oC for 8-9 h with 300 mL of n-hexanes. After extraction, the solvent was distilled off in vacuo at 45°C. The...

The BRO oil soap would not go rancid/ develop DOS.

I've been making CPLS for about an year. I dilute the paste in small batches and hadn't used any antioxidants or preservatives. the soap we use at home never gone bad. However, recently I came across two bottles I've gave away to my relatives, which had lost color and gone bad. Since then I'm...

Can we use both Sodium Benzoate & Phenoxyethanol in combination.

thank you every one for the responses, I came across another preservative, Phenoxyethanol which according to Wiki is effective upto ph10. Any thoughts on this

I'm was suggested to use Sodium Benzoate as the preservative in the liquid soaps. However, Wikipedia says Sodium Benzoate is effective upto pH 4.5 only. When I asked the chemist who suggested it, He said when molds grow they form a slightly acidic envirnment and the Sodium benzoate will become...

I was going thru a cosmetic supply website and came across this, the way it is written below; I felt it like a great ingredient for a handmade soap as a natural ingredient. Appreciate your thoughts on this Squalane and Squalene are oily substances that are common components of other oils. Both...

By the way I'm not keen to use any chemicals, in fact if I can make soaps without adding any chemicals, other than Lye, I would be more than happy. However the challenge is that Liquid soaps that I made and gave away to my brother went rancid and became unusable. I'm fine with it as it is within...

Dear Baqn 1. I see lot of red flags raised with regard to BHT above. the fun part is , when I was searching for videos on how to disolve BHT on YouTube, I even found a video prescribing BHT tablets daily as a health supplement. I'm not claiming any credibility based on that video, but my...

thanks for the detailed explanation I read http://cavemanchemistry.com/DreadedOrangeSpot-Dunn.pdf where it was concluded that BHT + EDTA giving the best result followed by ROE + EDTA. However I find it inconsistent with your first & second points. In point 4, do you meant to say the that BHT...

I'm planning to use BHT as the antioxident in my liquid & bar soaps. Since the recommended % are very small 0.1%- 0.5%, I find it difficult to measure in small quantities. Hence trying to create a solution containing higher concentration of BHT so that I can use in required amounts. This is...

In metric system, the volume and weight are interlinked using water as the base. 1 liter means the volume of 1,000 cubic centimeters (volume of 10cm X 10cm X 10cm container). 1 kilograms/1,000 grams means the weigh of the 1 liter of water. when the density is stated it's the weight of the 1...

you'll have to find out the density of each oil to convert the volume into weight vise versa. If I have note mistaken Coconut oil's density is about 0.924, which means 1 liter of oil will weigh 924grams.
