1. WaterSoft vs. Yerba Santa Protein for Skin Softness

Based on the search, information about "WaterSoft" was not found in the system. However, Yerba Santa Protein (Natural Silicone) is a glycoprotein obtained through fermentation. It has a silicone-like texture that provides a soft and smooth feel to the skin. It is suitable for formulations that aim to avoid silicones and desire natural ingredients for skin conditioning.

2. PhosphoMax™ (Natural Phospholipid Emulsifier)

• Does it require oil in the formula? PhosphoMax™ is a modified natural phospholipid emulsifier that can emulsify up to 20% oil. Therefore, an oil phase is necessary in the formula to create an emulsion.
• Recommended percentage for a light lotion: The recommended usage rate is 0.1-3.0%. For a light lotion, you might consider using a relatively low percentage within this range.
• How to use: PhosphoMax™ can withstand heat up to 80 degrees Celsius. The mixing method is to spin it to disperse in the oil phase first, and then combine it with the water phase.
• Is the mixing method similar to Phospholipid requiring 1000 rpm for 15 minutes? The specified mixing method for PhosphoMax™ is dispersing it in the oil phase and then combining with the water phase. It does not state that it requires high-speed stirring at least 1000 rpm for at least 15 minutes as you mentioned. The method you described might be specific to certain types of Phospholipids or special emulsification processes.
