突尼斯采购需求：纤维素醚生产商、供应商、羟丙基甲基纤维素、HPMC、纤维素醚、甲基纤维素

I am currently in the process of formulating a new intimate lubricant gel designed to meet cosmetic and medical device standards. To ensure the highest quality, I am looking for a premium Hydroxyethylcellulose (HEC) suitable for cold process manufacturing. The product should comply with either cosmetic or pharmaceutical grade specifications. My specific requirements include the use of HEC with the CAS number 9004-62-0 and the corresponding INCI name. I emphasize the importance of quality in this formulation, as it will be critical to the performance and safety of the final product. Please provide information on your available grades, their specifications, and any relevant certifications or testing data. Thank you!
