I agree … hard to believe that 0.5% of these plant extracts would be the source of malodor in your product. Are you using liquid extracts?
Without knowing what other ingredients you are using in the formulation, hard to give you any better advice.Carrubba has a line of natural fragrances that would be worth your consideration. -
Yes, you can first wash by hand with soap/water, then throw then in the dishwasher. Finally, just dip in an 90% Isopropyl alcohol bath and let them air dry right before use. Always wear gloves when making a batch.

Hydrogenated Polyisobutene is generally used at up to 10% … you’ll have to experiment with it in your formulation. And, Yes, Castor Oil may be irritating to some people.
@summerstar: What are you using to remove the lipstick? Perhaps it’s something in your makeup remover and not necessarily the lipstick itself … Mineral oil is generally used as a moisturizer. Next question: Are you the only person this happens to, or does the drying occur to a large proportion of people who use your makeup? -
I would use all three.

By regulation, products containing alpha hydroxy acids cannot have a pH lower than pH 3.5 and must have specific sunburn warning verbiage on the label if it’s a consumer OTC product. Now, peels targeted to the professional market, no problem.

Best you be cautious, and honest … Take a look at your ingredients list and see if they are on the ECOCert list of acceptable ingredients. You can then either calculate the % of natural ingredients (by weight) in your product or you can put an asterisk next to the ingredients in you ingredients list and below it put
* Natural IngredientsBill_Toge gives you good advice. Arm & Hammer called their stick deodorant “Natural” even though it contained Tricolsan and other synthetic ingredients. In New Jersey, the got hit with a class action lawsuit for misleading advertising and they lost. So, even though “Natural” has no legal meaning … use it judiciously. -
You must first add the Dissolvine GL to room temperature water and stir well to incorporate. Dissolvine GL is usually the first ingredient that I add to the water phase when using it in a formulation.

I’ve personally always found Xanthan Gum easier to work with than HEC. It also helps if you first “pre-hydrate” the Xanthan Gum or HEC in Glycerin to form a slurry and add the slurry to the room temperature water with rapid stirring. The glycerin will help prevent the Gum from agglomerating.

Try J Edwards International

Well, the first question is why exactly is it that you are adding Vitamin E to your liquid soap … what function do you expect the Vitamin E to perform?
Tocopherol Acetate … Least expensive option if your objective is to prevent rancidity in oils in your formulation.dl alpha Tocopherol … if you want to include a skin-beneficial antioxidant in your formulationTocotrienols … about 40X more effective than dl alpha tocopherol as a skin-beneficial antioxidantGenerally, you can include Tocopherols at 0.5% to 1.0% -
Try throwing in some Tocopherol, Tocopherol Acetate or CO2 Rosemary Extract as antioxidants. I would also switch from a dry powder algae extract to a liquid extract. You can purchase from a number of vendors.
Over what timeframe does it turn brown?Are you buying the Algae Powder Extract from a reputable source, or are you buying it from China? I find the Chinese powder extracts always seem to be adulterated so I never use them. -
@Bobz
I was being facetious … Highly likely the formula simply will not work … for reasons that are self evident from looking at the proposed formulation -
@Bobz:
The answer should be self-evident. -
$1.25 million for a 1,500 sq ft house!

My guess is that they are including the Lactic Acid as a multifunctional to (1) Adjust the pH and (2) Lactic Acid will strip the outer keratin layer to make hair softer and more manageable. Is this a general purpose shampoo is it a shampoo targeted at people who have thick, hard to manage hair?

Sodium Hyaluronate is the sodium salt of hyaluronic acid. It is what is most commonly used in topical cosmetic products. You can purchase sodium hyaluronate from several sources in a wide variety of molecular weights. Just get on ulprospector.com or google Sodium Hyaluronate suppliers.

@EliseCortes
Forgot to mention, if you observe any precipitation, just raise the pH to 4.0 or so, that will help ensure the SA stays in solution. Just add some Sodium Lactate to get the pH up. -
@EliseCortes
What are you using as your Oil phase? It’s probably much simpler than you think.Method 1: Dissolve the Salicylic Acid in your Oil phase, which can include Octyldodecanol. Add 1% Sodium Citrate to your water phase. When you combine to make the emulsion, the SA will be solubilized.Method 2: Dissolve the SA in 1,3-Propanediol by heating it and then add this to your hot Aqueous Phase that includes 1% Sodium Citrate right before you combine the Aqueous Phase with your Oil Phase to form the emulsion. Again, you can include Octyldodecanol in your Oil Phase. -
Yes, 0.1% to 0.5% of either works well. Yes, they work with most oils. They are not mutually-exclusive, you can add a bit of each or use them individually.

Dave, you do not need a preservative for hemp oil … what you need is an antioxidant … as Belassi said, you can add Vitamin E (tocopherol) or a CO2 Extract of Rosemary. Either will help in your hemp oil becoming rancid.

“Could it be that lauric acid in purified form is somehow different from the one in coconut oil, and it makes me wary to use it on the skin in a moisturizer as it tastes like soap.”
If it’s Lauric Acid in the coconut oil, then it is also Lauric Acid when purified. Chemically, there is no difference.Scratching my head on the correlation between tasting like soap and effectiveness in a moisturizer … -
There are reports that Lauric Acid can be a skin irritant.

Be happy to take a look at it Perry.

@DrA
There is really a dearth of information online regarding serums. IMHO, it really is a marketing term, but generally serum implies a formulation with a minimal number of ingredients, but with a high concentration of actives.
Yes, you are correct, you will find everything from anhydrous systems to lotions labelled as “serums”
