I would like to ask about the rancid smell from Safflower Seed Oil. The description mentions it might have a rancid smell. If I mix it into a cosmetic formulation, will it make the cosmetic product smell rancid? Also, I want to ask about the Shelf Life specified for each ingredient. If I mix them into a cosmetic product, will the shelf life follow that of the individual ingredients, or will it be counted from the date the cosmetic is mixed? Thank you.

I have a stable base formula (Formula 1) and encountered problems when adding other ingredients in subsequent formulas (Formulas 2, 3, 4). I suspect incompatibility between Silicone quick cond, Jojoba ester, and Polyconditioner easy. **Formula 1 (Stable Base):** * makeupwash: 3% * cocowash: 3% * Isopentyldiol: 10% * Polyconditioner.easy: 4% * Silicone.quick.cond: 5% * MOIST24: 8% * Cucumber: 5% * Aloe: 3% * Phenoxyethanol.SA: 1% * Water: 58% **Formula 2 (Adding to Formula 1 base):** * Condi-B5: 4% * Jojoba.ester: 5% * HyaCoat: 0.2% **Procedure for Formula 2:** Added Condi-B5, then Jojoba.ester. Jojoba.ester did not seem to dissolve. High-speed mixing and heating (below 70°C) did not improve the issue. The problem looks like a combination of polymers. **Formula 3:** * Jojoba.ester: 5% * Condi-B5: 4% * B3: 3% * GlucoBright: 3% * Phenoxyethanol: 1% * Polyconditioner.easy: 8% (accidentally added 4% extra, total 8%) **Procedure for Formula 3:** Dissolved Jojoba.ester in water first, then added other ingredients top-down. After adding Polyconditioner.easy, the result was a mucus-like, separated mixture. **Formula 4:** * makeupwash: 3% * cocowash: 3% * Isopentyldiol: 10% * Polyconditioner.easy: 2% * Silicone.quick.cond: 5% * MOIST24: 8% * Cucumber: 5% * Aloe: 3% * Phenoxyethanol.SA: 1% * Water: q.s. to 100% * Condi-B5: 4% * Jojoba.ester: 5% **Procedure for Formula 4:** Started by dissolving Jojoba.ester in water and warming until dissolved, then added Polyconditioner.easy --> Condi-B5 --> Silicone.quick.cond. After adding Silicone.quick.cond, a cloudy, stringy mucus formed. High-speed mixing did not help. **Summary of Questions:** 1. What is the cause of the problem in Formula 2? 2. What is the cause of the problem in Formula 3? 3. What is the cause of the problem in Formula 4? 4. Which ingredients are incompatible? I read the website descriptions and none mention incompatibility. 5. Please provide guidance on how to fix these issues, as I have run out of materials to continue testing.

I need advice on coloring a physical sunscreen with a Water in Oil emulsion base. The formula contains 13% mineral oil. I want to achieve a skin tone color similar to sponge number 2 using Beige Iron Oxides EasyMix. My plan is to add the color after the oil phase and water phase are emulsified, at a temperature below 60°C, sifting it in along with Zinc Oxide, Kaolin, and Titanium Dioxide. I will be using simple mixing equipment (hand stirring or an egg beater). Is this color choice suitable? What percentage should I start with for testing the color?

I want to make infused oil to use the extracted oil in a face oil formulation. However, based on my research, natural oils like almond oil, coconut oil, and olive oil don't have a long shelf life if not preserved, or they can go rancid if not stored properly. I would like to know: 1. If adding Vitamin E oil to the oil will help extend its life and quality, and for how long? 2. If I want to add a preservative suitable for sensitive skin to the oil, which one should I use, how should it be used, and what is the recommended percentage? 3. Is Vitamin E oil considered a preservative?

I am trying to formulate an O/S/W and S/W cream containing approximately 10% silicone (like Cyclomethicone). The formula also includes electrolytes from: * Sodium PCA 50% - 5% * Sodium Lactate (60% Liquid) - 5% I have tried various cream makers at high concentrations: * Satin Cream Maker - 3% + Pro Polymer - 3%: Can emulsify silicone but doesn't achieve the desired thickness. * Silk Cream Maker - 3% + Pro Polymer - 3%: Can emulsify silicone but doesn't achieve the desired thickness. * HEC - 3% + Satin Cream Maker - 1%: Can emulsify silicone and achieves close to the desired thickness, but causes significant pilling after application. The formula closest to the desired cream texture uses: * Butter Cream Maker - 4% + Cetyl Alcohol (Vegetable) - 3% + Cyclomethicone / Cyclopentasiloxane (Low-Odor) - 10% This formula achieves a texture close to desired after 24 hours, but I am unsure if it effectively emulsifies the silicone or if Satin Cream Maker is necessary to assist with silicone emulsification. Therefore, I have the following questions: 1. Can Butter Cream Maker, Milk Lotion Maker, Laureth-7, or Steareth-2 effectively emulsify silicone/water in this formula, or is Satin Cream Maker needed to assist? 2. Can cream makers like Satin Cream Maker, Light Cream Maker, Silk Cream Maker, or Luxury Cream Maker tolerate heat if used together with Butter Cream Maker? 3. If I use Easy Cream Maker + Glyceryl Stearate SE, can it emulsify silicone/water? 4. Can Aculyn 22 (Acrylates/Steareth-20 Methacrylate Copolymer) at >= 1.25% tolerate the electrolytes in this formula? 5. Alternatively, should this formula be changed to a water in silicone system? I would appreciate any suggestions for alternative emulsifiers or additional recommendations. Additionally, I am interested in Hydroxypropyl Chitosan (HPCH) for nail care in a hand cream formulation. I couldn't find it on your website. Do you carry this ingredient, or do you have any other recommended active ingredients for nail conditioning? Apologies for the lengthy question.
