I have a liquid cleaning solution for leather sofas with the following ingredients: liquid detergent, multipurpose cleaner, Oxiclean, fabric softener, galsoft (for foam texture), and water.

After applying a formulation containing AcnePLEX 5%, Safe-B3™ 5%, NAG 4%, and Epidermal Growth Factor (EGF) 3%, I experienced itching, tingling, and easy redness upon scratching in the application area. I have regularly used B3 5% and NAG 4% without issues, and EGF 3% was introduced along with AcnePLEX 5%. Is this reaction caused by irritation from AcnePLEX or an allergic reaction?

I would like to ask what ingredient is causing formula separation. The formula is as follows: Aluminum Chlorohydrate 10%, Triethyl citrate 2%, Ethyl Ascorbic acid 2%, Disodium EDTA 0.2%, Butylene Glycol 10%, Menthone Glycerin Acetal 10%, Propanediol : Ethylhexylglycerin 1%, Water qs 100. Is the separation caused by the cooling agent, Menthone Glycerin Acetal (Freeze Me™), being incompatible with the formula? Does using it in a formula with a pH of approximately 4 cause separation? Thank you.

When ordering ingredients, there is a recommended usage rate. Is this recommended percentage the concentration at which the active ingredient is effective and stable? I read research, for example, on [url=http://www.myskinrecipes.com/shop/%E0%B9%80%E0%B8%9B%E0%B9%8A%E0%B8%9B%E0%B9%84%E0%B8%97%E0%B8%94%E0%B9%8C%E0%B8%A5%E0%B8%94%E0%B8%A3%E0%B8%B4%E0%B9%89%E0%B8%A7%E0%B8%A3%E0%B8%AD%E0%B8%A2/762-madecassoside-centella-asiatica-extract.html:29rqzqkv]Centella Asiatica extract[/url:29rqzqkv], which is often used at around 5% to be effective, but the recommended percentage here is 1%. I am unsure if using the recommended percentage will provide good skin absorption effectiveness or stability.

I would like advice on a formula for a spray to be used on pillows and beds for relaxation and comfortable sleep. I'm concerned that using the same formula as regular perfume might be too strong and intense. I plan to use Essential Oils, but what else should I mix with them? I want the resulting mixture to be gentle and have a pleasant scent. Longevity is not the main focus; the priority is gentleness and the ability for the scent to diffuse throughout the room.
