@vchemie: Glyceryl Caprylate (and) Glyceryl Undecylenate works well in anhydrous formulas
-
Your best approach with a new line is to target a niche market with a superior product with some unique ingredients or ingredient combinations that fulfills a need and the potential consumers are easily targeted through various channels ... Baby &am…

@chippy: To get an effect, you would have to use the concentrated active triterpenes from Gotu Kola ... asiatic acid, madecassic acid, asiaticoside ... but, you would need to acquire those from a manufacturer in bulk. You will not find those from …

No, just mix it until it is uniform ... should take just a few minutes
-
@biolum Bakuchiol is quite viscous, so your best bet is to mix it properly with a magnetic stirrer or overhead stirrer. Heat is not necessary.

@Beryl01 Shea Nut Oil is available from Jedwards Intl and other suppliers.
-
@Graillotion: Why not just remove the Vanillin? Regardless of what else you throw in there, Tumeric, Sea Buckthorn, the browning of the vanillin will still discolor the product ... it will just be a brownish yellow instead of beige.
-
The old cold cream or vanishing cream formulas are actually Stearic Acid and Potassium Hydroxide ... you don't need beeswax at all. These are more super-granola, birkenstock, all natural formulas ... I don't find them to be elegant at all ... the…

As I explained to one of my clients who wanted to develop one of these non-emulsifier/non-preservative balms for Eczema: It is more dangerous to put a potentially contaminated product on compromised skin than it is to use a preservative. And, thes…
-
@katerinak: I have been tasked with developed formulas similar to this on a handful of occasions now. Basically, it's a water-in-oil "emulsion" and the sorcery is to add the Water, Honey, Glycerin phase very slowly under homogenization t…
-
I don't know how this discussion swung from an announced change in marketing langauge by L'Oreal to products being banned ... that's not at all what L'Oreal is saying. They are announcing that they will no longer use certain words in their product …
-
@simranpatel: Certainly if you are an esthetician that would be useful experience as a grounding for cosmetic chemistry & formulating. What are you currently studying? Getting a job with a contract manufacturer would be even better to get som…
-
@africanbug: That's more clear ... It sounds like you are simply stirring it too much. (1) Add the SCI to water and heat to 90C - 95C. Do not stir, just let the heat melt the SCI pellets. (2) Allow (1) to cool to 70C and add the Coco Betaine wh…
-
Sodium Cocoyl Isethionate and Coco Betaine are both surfactants ... so, of course they foam. There is nothing "weird" about the foaming, it's what surfactants do.
-
@PeaceLoveNaturals: If you heat your Water Phase and Oil Phase at the same time and immediately before adding the two together you will not have this problem. Sounds like you're heating up the Oil Phase and then letting it sit for a while before a…
-
@promises: Why do you not just make a face oil using tetrahexadecyl ascorbate as your form of Vitamin C ... it is oil soluble.
-
My ... this is one hot mess. @Rucrasha ... try this: Water, Aloe Vera Leaf Juice, Coconut Water, Castile Soap, Sucrose Cocoate, Xanthan Gum, Fragrance, Preservative. This is going to have a pH of about 9.0+, so it's not really a great shampoo for…
-
@chickenskin: You are required to list the INCI name of the ingredient on the label. Often, ingredients will have other components that are processing aids that do not need to be listed on the LOI ... just follow the INCI name for the ingredient a…
-
@Africanbug: When you cold process Sucrose Stearate you're going to introduce lots of air into the emulsion if you do not first add the Xanthan Gum/Glycerin slurry. So, change your procedure to first add Xanthan/Glycerin to water stirring to hydra…
-
@helenhelen It has to do with the formation of the packing structures of the liquid crystals ... it's a different organization if you add the LC Emulsifier first to water as opposed to adding the LC Emulsifier first to oil. You get a different sk…
-
@helenhelen: Yes, you should add liquid crystal emulsifiers, such as Olivem 1000, to the water phase.
-
@Graillotion: No, that would not be appropriate. If you have 1.0% 100X or 0.5% 200X Aloe Powder, then it is essentially reconstituted Aloe Vera Juice and you can list it Aloe Juice as your first ingredient. If it is less than those amount, then i…
-
@MLJ: Not at all ... I commonly make surfactants with Aloe Vera Juice instead of water ... there is no "too much". The maximum amount of powder you would want to add is 1% of 100X
-
@NicolB: Dihydroxyethyl Cocamine Oxide and Glycereth-17 Cocoate
-
You can use either CCT or C 12-15 Alkyl Benzoate as a carrier for the ZnO
-
@Shelly1981: If you have a robust preservation system, you really do not need to "pre-treat" the clay ... the preservative will resolve any pre-contamination issues.
-
@blackbird: You really don't need a co-emulsifier with Cetearyl Glucoside (and) Cetearyl Alcohol, but if you want to use a second emulsifier, just go with Glyceryl Stearate.
-
@Halim: Is "parfum" in your formula a fragrance or a preservative. If it is a fragrance, that is your most likely culprit causing irritation.
-
If you add 1% of the powder it will reconstitute to Aloe Vera Leaf Juice. There is no "normal" amount ... it's as little or as much as you want.
-
@Shams Yes, sunscreens are regulated as OTC drug products in the US. Your product must be registered with the FDA and must be manufactured in an FDA OTC-certified facility. GRASE means Generally Regarded As Safe & Effective. If ZnO is the…
