Hi hope you are well. I would like to check if the manufacturer actually did SPF testing to substantiate claims for **Light Moisturizing Sunscreen (SPF50+, PA++++, Compare to Beauty of Joseon)** or if the testing would need to be performed by me if I would like to sell it under my brand in the UK. Also, the laboratory was asking for formula percentages; would it be possible to obtain this? Many thanks

Hello, I was wondering what glycol ratio is required for dissolving Hi-LiconeA™ Licorice Extract (Licochalcone A 20%)? Ideally I want to use pentylene glycol or propanediol, but if either of those won't work then ethoxydiglycol. I am planning on using 0.3% of the ingredient. I also had the same question about WhiteCumin™ (Tetrahydrodiferuloylmethane).

I want a mosquito repellent lotion with IR3535 (for both adults and children). The formulation should be able to handle summer temperatures of 50°C. I am looking for suggestions on whether my formulation is missing any ingredients or if any are overloaded. Please provide suggestions using INCI names so I can search for them easily (I cannot purchase ingredients directly from this website). I am testing IR3535 at 5%, 8%, and 10%. My current recipe failed. **Current Formulation (10% IR3535):** * IR3535: 10% * PG: 7% * Cetyl Alcohol: 5% * PEG-100 stearate: 3.5% * CCTG: 3.5% * Polyacrylate Cross Polymer: 2% * Tween-20: 1.2% * Preservative: 1% * IPM: 2% * Aqua: Q.S. In this formulation, the oil separates after some time. Also, what should the pH be for this type of product?

Hello, I am currently testing the **Hydrolyzed Sclerotium Gum** in a water-based formulation, and I have a few questions regarding its incorporation: * **Clarity:** Upon adding the powder, the transparent base became cloudy/turbid. Is this expected, or should it remain clear at a specific dosage? * **Solubility:** The powder is proving difficult to dissolve. Even after extended manual stirring, I can still see small, transparent particles in the solution. * **Gelling:** Are these particles a sign of incomplete hydration or a characteristic of the product's gelling behavior? Could you please provide the recommended incorporation protocol? Specifically, should it be pre-dispersed in a humectant (like **Glycerin**) or require high-shear mixing to ensure full hydration? Thank you for your technical support.

I'm having lots of trouble wetting silica dimethyl silylate in my lip gloss formula. I have tried pre-wetting by adding slowly to Pentaerythrityl Tetraisostearate and mixing. I don't have an overhead stirrer, so this may be impossible. I have a mixer with one blade for non-shear and a homogenizer. I would really rather not use the SDS, is there a replacement that is premade gelling to help suspend my pigments? I use mostly micas, but small amounts of lakes and oxides too. This is my current formula. Would appreciate if you could suggest another ingredient that doesn't require wetting, ready to use, or if something in my ingredients will work at a different percentage. | Ingredient | Percentage | | :--- | :--- | | Hydrogenated Polyisobutene (300cs) | 21.30% | | Polybutene (2400 MW) | 13.50% | | Bis‑Diglyceryl Polyacyladipate‑2 | 9.50% | | Tridecyl Trimellitate | 5.00% | | Hydrogenated Poly (C6-14 Olefin) Gel | 4.00% | | Octyldodecyl Stearoyl Stearate | 2.00% | | Hydrogenated Poly (C6-14 Olefin) (6cs) | 11.00% | | **Heat to 80-85 deg and dissolve DPHP and Penta TDBH:** | | | Pentaerythrityl Tetraisostearate | 4.00% | | Silica Dimethyl Silylate | 1.50% | | DIPALMITOYL HYDROXYPROLINE (needs to be heated to 80-85 deg) | 0.50% | | Pentaerythrityl tetra-di-t-butyl hydroxyhydrocinnamate | 0.10% | | **Pigment blends (make syrup):** | | | Diisostearyl Malate | 8.50% | | Polyglyceryl-2 isostearate/dimer dilinoleate copolymer | 10.50% | | Pigment blends (make syrup with above solvents) | 6.50% | | Boron Nitride | 0.70% | | Lauroyl lysine | 0.20% | | **Add after cools to 40 deg:** | | | Sweet Cherry Oil | 0.90% | | Flavour Oil | 0.30% | | **TOTAL** | **100.00%** |

Hello. I have several large dogs at home and want to make a multi-purpose cleaning and deodorizing solution that actually works. It would be for mopping floors, cleaning bathrooms, disinfecting, and neutralizing urine smells, dog odors, and food smells. Is this possible? I want it to be a concentrate that is diluted before use. I'm looking for two types of formulas: 1. **Heavy-Duty/Concentrated:** A formula that turns cloudy when mixed with water (like Dettol) for strong odors like dog urine. I want to neutralize the odor at the source. Are there other recommendations besides Dettol? I only want to add perfume for a pleasant scent. 2. **Daily Use:** A formula for everyday mopping, mixed with water, with some fragrance, but higher quality than general floor cleaners. I want it to be as gentle as possible for children and pets. Please recommend disinfectants. I have used BKC before.
