How do you formulate a sulfate-free shampoo that still cleans well and foams in hard water?

Quick Answer (for busy buyers)

Here’s the buyer-first summary. If your brand name is on the label, you usually act as the responsible person and must ensure the listing is submitted and kept current.

• Formulating a sulfate-free shampoo that cleans well and foams in hard water requires replacing sulfates with gentle surfactants such as sodium lauryl glucose carboxylate or glucosides, and incorporating chelating agents like EDTA to counteract mineral ions.
• We optimize viscosity and pH through lab trials for stability and performance.
• For OEM projects, MOQ typically starts at 1000 units to balance batch costs, with sampling taking 2-3 weeks for initial prototypes including foam and compatibility tests.
• We conduct essential testing like microbial checks, 3-month stability trials, and foam volume assessments under simulated hard water conditions.
• Documentation includes a Product Information File and safety assessment per EU Regulation 1223/2009, and we advise on labeling for EU markets.
• Packaging must be leakage-resistant, often using PET bottles with compatible pumps, and production lead time is 6-8 weeks after sample approval.
• We support with testing protocols and compliance guidance but recommend clients verify final regulatory approval locally.
