I need a gel mask that can be used on both the face and lips. My formula is as follows: * water: 83 * 4D hya: 5 * butylene: 5 * Panthenol powder: 1 * Glycerin: 5 * Xanthan Gum: 0.2 * Dipotassium Glycyrrhizate: 0.1 * Phenoxyethanol SA: 0.7 After testing the formula on my face for 15 minutes and wiping it off, I felt a tingling sensation on my lips. I suspect it might be due to Phenoxyethanol SA. 1. Do you have any recommendations for a preservative that is suitable for this formula and can be used on the lips? 2. Global Globe's pH should not exceed 5.5. I am concerned if it can be used with this formula, as the range is quite narrow. 3. Besides the preservative, are there any other ingredients in this formula that could potentially cause a tingling sensation on the lips?

I have the following sunscreen formulation: * Titanium Dioxide 15nm Liquid: 10% * Zinc Oxide 35nm Liquid: 10% * Silicone Gel (Ultra Clear): 28% * PMMA Booster: 5% * Silicone Blender: 3% * Beige Iron Oxides EasyMix™: 0.15% * Mild Preserved Eco™: 1% * Water: 42.85% The resulting sunscreen texture is quite thick but easy to spread. I would like to achieve a more fluid texture. I have a few questions regarding adjustments: 1. Which ingredients should I increase or decrease? For example, can I replace `Silicone Gel` (Ultra Clear) with `Cyclopentasiloxane`? Will this make the texture more fluid, and what percentage should I use? 2. If I switch to using `Cyclopentasiloxane`, do I still need to include `Silicone Blender` for emulsification, or should I use a different base? What percentage should I use to achieve a fluid texture? 3. Will using `Cyclopentopentasiloxane` affect the waterproof property of the sunscreen? If it reduces water resistance, how can I address this?

I would like to inquire about the MSDS for the amino acid product sold. Is it possible now or is there a chance in the future that the company will choose a version without **Methylparaben** and **Propylparaben** as preservatives, which are found in the extract?

Could you please recommend a formula for an anti-pollution sunscreen (PM 2.5 and dust/smoke pollution)? I would like it to have the following properties: 1. Protect the skin from both UVA-UVB radiation with **SPF50+ PA+++**. 2. Be a **physical sunscreen**, which is highly stable and contains fewer chemical components than **chemical sunscreen**, thus reducing the chance of allergic reactions for those with weak, sensitive skin. 3. Contain ingredients that help with **anti adhesion** to reduce the adherence of pollution on the skin (e.g., Ectoin, Fucus Film™). 4. Contain ingredients that act as a **skin barrier**, such as Cica, Ceramide, and Niacinamide, which strengthen the outer skin layer and reduce the chance of irritation from pollution. 5. Contain moisturizer ingredients to help keep the skin hydrated, as dry skin is prone to itching and irritation. 6. Be free from ingredients that can cause allergies, such as น้ำหอม, paraben, colorants, and artificial scents. Also, I would like to know the price for producing a 50ml quantity.

I would like to ask about using Glyceryl Stearate SE and Pentaerythrityl Distearate in cream formulations. 1. Can Glyceryl Stearate SE be used to create a cream texture directly (without oil)? If so, what percentage should be used? (Mixing in water + electrolyte-free formula, sometimes pure water). 2. Can Glyceryl Stearate SE emulsify water + oil? 3. Can Pentaerythrityl Distearate emulsify both water + oil? What percentage should be used? 4. If it can emulsify, how much oil can it support? 4.1. If it cannot emulsify water, can Pentaerythrityl Distearate be used together with Glyceryl Stearate SE to emulsify water + oil? If I want to emulsify 70% oil and 30% water, what percentage of each should I use? What kind of texture would result? If I want to increase viscosity or thickness, what ratio of SE:Distearate should I add? If I want to increase oil in the formula, what ratio should I add Distearate per oil? For example, in a formula like this: * Water 30% * SE (what percentage should I use? Please help answer this) * Oil 70% * DISTEARATE (what percentage should I use together? I don't know) If I get the percentages for both, I will reduce the oil to make it 100% total. For example, if I use SE 5% and DISTEARATE 5%, I will reduce the oil to 60% and water to 30%. I would like detailed information on how to create a cream texture using these two ingredients to emulsify water and oil (without using 'MAKER'). 5. What is the HLB value and how is it calculated? I need very detailed information as I am not very familiar with using emulsifiers like 'MAKER' and often encounter issues with texture or equipment (perhaps due to lack of knowledge). I want to be able to create cream texture myself. Thank you.
