Type your messageHere's the formula for my most recent lotion. It still needs some improving but I don't know what I should add/ remove. My previous formula had grapeseed oil but that wasn't moisturising at all. I assumed this was because of how high the linoleic acid content was in the oil.
Body lotion - 2000g
Water phase -68%
Water 60% - 1200g
Glycerin 5% - 100g
Niacinamide 2.5% -50g
allantoin (add at 54°) 0.5%- 20g
Oil - 28%
Glyceryl stearate & Peg 100 5% - 100g
Cetyl alcohol 4% - 80g
Sesame oil 16% - 320g
Petroleum jelly 3% - 60g
Cool down under 45° - 4%
Phenoxyethanol & Ethylhexylglycerin 1% - 20g
Rice protein cool down - 3% 60g
- Which of the ingredients in my formula are a potential irritant?
I'm wondering if any of these ingredients are known eczema irritantants. I don't particularly break out when apply to the skin but areas with existing eczema so appear slightly more red. I've also noticed that my skin healing is noticeably slower than what should be normal, even parts of my skin that I stopped scratching is healing very slowly (I have extremely dry skin and a compromised skin barrier). Even with a plethora of ingredients touted for their numerous benefits, I've yet to see improvement in my skin barrier. Which leads me to believe that something is damaging my skin. I've been making really basic lotions for two years. the inclusion of allantoin, rice protein and niacinamide are additions to my two most recent batches.
*I am aware that cosmetology and dermatology are separate entities. My lotions are for my personal use and any of my experiences are purely anecdotal. As such, I will not use any opinions expressed in this thread as a replacement for professional medical advice.
- the formula feels like it's lacking emolliency/ moisturisation.
When I apply the lotion, I feel like it gets 70% of the way there but my skin is never fully moisturised. I often end up lathering too much lotion, making even the dryest carrier oil really greasy. Even then, the lotion will not last long and my skin begins feeling dry again after an hour or so. I can never get my formula to have the same moisturising feel as a commercial lotion (I'll use aveeno as a reference).
Which ingredient is it that I'm missing, something that softens the skin, lasts long but also absorbs quickly. Maybe it's a silicone? I tried to purchase dimethicone but it's hard to commercially source commercially in the UK.
I would greatly appreciate if someone could tweak my formula for me. If you suggest new ingredients to add, can you suggest something that's commercially assessible.
Thanks for taking your time out to read my post.
