美国采购需求：天然油、卡斯蒂利亚肥皂、护手霜、护肤品

I have a couple of inquiries regarding your Pure Castile Liquid Soap that I'd appreciate your insight on. First, could you provide an approximate percentage of coconut oil in your formulation? While I don't have an allergy, I want to ensure it won't cause any potential irritation for my clientele. Additionally, I'm interested in how best to use the soap in a foaming dispenser. What's the ideal water-to-soap ratio you recommend for optimal performance? Looking forward to your detailed response on these aspects!
