  • What’s making me sweat?

    Posted by Stacy88 on October 1, 2020 at 12:45 pm

    I’m new here. I’ve been making my body lotion doe a year now. But wherever I apply it, I start sweating and have to sit under the fan to dry up. Once dried I don’t sweat again. How to I stop that sweating after applying it?  
    I add glycerin 2%
    Propylene glycol 2%
    E wax 4%
    Celty alcohol 2%
    Vitamin E 1%
    Preservative 1%
    EO 1%
    Oils 10%
    The rest is water

    What’s the EO you’re using? It looks like the only likely culprit to me.

    @LincsChemist tea tree and I later switched to carrot seed oil.

    I’d recommend you try a version with no essential oils in and see if that solves the issue.

    Sounds like an allergic reaction to something. It could also be the preservative. What are you using?

    I’ll try that

    You did not mention time of application (related to bathing), and the humidity of your environment?

    I live on the wet side of Hawaii….where humidity is often above 90%.  I find it is simply the humectants being effective….that I get what appears to be sweat…if I apply immediately after showering, on a humid day.

    I know from chats with other members in places like Singapore, they have to limit or monitor humectant levels, to reflect their environment.

    If you live in a dry climate….you can pile them on.  If you live in a very humid climate…they will do their job…..in excess! :)

    Well I live in Nigeria and it’s very hot here. I apply it right after bathing. I made a small batch 2days ago without glycerin and still got the sweating. Could it be my location?

    Well…in order to test the theory of humectants….make a small batch without the Propylene glycol, (and without the glycerin) and see if you still sweat.

    Just my younger sister sweats with it. But my older sister doesn’t sweat at all.

    Done that already and it’s still the same thing. I’m guessing it the e wax

    Yes…I think the next most likely culprit.

    @Stacy88 Yes, I was going to suggest the wax, which would form a film reducing water loss. Maybe you can try one without it and start increasing to 1%, or switching to a different type of solid like Glycol distearate.

    right after bathing - some might find yourself sweating more than you expected because sweat and sebum have been washed off, your sweat glands want to achieve their natural function.
    Armpits tend to sweat more after day bath than after night bath.

    for further reading see Apoeccrine sweat glands.  

    have you compared the amount of sweat using your doe vs not using anything at all?

    if it is about the same amount I would say your cream is fine.

    Oils 10% - or maybe your oil is too occlusive, try sub with non-occlusive 
    PPG-15 Stearyl Ether and Isostearic acid.

    @Pattsi - “…some might find yourself sweating more than you expected… “

    This is a very interesting question. I have experienced this (especially after going for a run then showering). I wonder if the cause has really been studied or if it is simply a logical deduction based on theories of how the sweat system works.  I do not know.  Must look into this further…

    Could you list the oils you are using?

    I concur, I typically sweat after a shower, but I always thought it was because of this:

    I shower typically after doing physical labor, so my core temperature is elevated.  Add to that, I shower in warm water, compounding the warming of the body.

    Therefore I felt that my body was just doing its job of cooling, by sweating in an attempt to lower the core temp, plus the elevated skin temp from the shower water.

    I have started applying the moisturizer about 30 min after the shower, and that seems to help.  I do NOT suffer from dry skin.

    I live in singapore and its very hot, humidity above 80% most of the time. Thick lotions or creams make me sweat. I can use a toner (with high levels of humectants), but wont sweat. So i guess oil + ewax must be the culprit for my case.

    I made thin liquid lotion and i didnt get this sweating problem.

    I haven’t come across such study, pls do share what you find.

    Apoeccrine sweat glands

    A third type of sweat gland, only recently described by Sato et al. in 1987 [23,24] is the apoeccrine gland. Apoeccrine glands develop from eccrine sweat glands between the ages of ~8 to 14 years and increase to as high as 45% of the total axillary glands by age 16–18 [23]. They are intermediate in size, but as the name suggests, apoeccrine glands share properties with both eccrine and apocrine glands. Like apoeccrine glands, apoeccrine glands are limited in distribution, as they are contained to only the axillary region. Apoeccrine glands are more similar to eccrine glands in that the distal duct connects to and empties sweat directly onto skin surface [23]. In addition, the apoeccrine gland produces copious salt water secretions similar to eccrine sweat [23]. The function of this secretion is unknown, but unlikely to play a significant role in thermoregulation since evaporation is inefficient in the axilla region. The innervation of the apocrine gland is still poorly understood, but in vitro models suggest the apocrine gland is more sensitive to cholinergic than adrenergic stimuli [23,24].

    Many factors affect cholinergic innervation including temp that’s why armpit sweat is hard in management, so just botox it and done.

    This is common. And this the reason why High Intensity Interval Training can have fat-burning effect which lasts for many hours even when you are at rest or asleep.

    @Stacy88

    It is the high content of lipids in your formulation. I live in Malaysia, in the tropics. High temperature plus high relative humidity is very bad in many ways. I struggled much wondering what was wrong with me. LMAO! That was when I started making my own moisturiser; I was a noob. I still experienced the same because I copied formulations of temperate climate exactly. I later learnt that I am not the only one experiencing weirdness.

    Also, I learnt that advice and methods suited for temperate climate cannot be applied in the tropics. Same goes for gardening/agriculture. I killed many lavender and rosemary in the past just because I allowed them to go ‘dry’ and ‘under full sun’, which is the only advice to growing those species successfully. 

    I will tell you my story. More like jouney.

    My very first DIY moisturiser was with Behentrimonium Chloride/Methosulphate. Only 3% but it is too rich. I wondered why as I saw sweat on my nose immediately after I applied the moisturiser.

    After knowing Behentrimonium Chrloride/Methosulphate is too rich, I moved to using Cetyl Alcohol. Same thing. Very low amount but I sweat. I wondered why.

    I tried many substances over the years. Much effort and money gone down the drain. That was when I learnt that many stuff such as Hyaluronic Acid/Sodium Hyaluronate, Saccharide Isomerate (trade name is ‘Pentavitin’), etc, are just marketing. Companies like that are no different to doctors. Doctors may know how a drug work but impossible that they know which one works for which individual with which specific sickness, especially new drugs are constantly churning out in the name of money. Many of them nowadays are promoting natural and organic cures! Pharmacists are the same, telling people to swallow certain organic/natural supplements as cure! Medical science is dead. The good old day chemist (named ‘pharmacist’ in modern days) is dead.

    My formulation got stupid simpler and simpler, and stupidly minimalistic. Zero lipid and very very small amount of humectants.

    Sorbitol
    Xanthan Gum
    Glucono delta Lactone (basically hydrolysed into gluconic acid and lactone once it touches water)
    DMDM Hydantoin
    Potassium Sorbate

    Yeah! That simple! Absolutely zero commercial value. Most substances are from the bakery shop! But it is all right because it is for my own use, and it is perfect for my oily skin and the climate that I am in. I gave few samples to a few friends and they said excellent, so they actually pay me to provide them with the product.
