Non-Sticky Clear Gel Maker for Body Serum with 20% Extracts

For a body serum containing up to 20% natural extracts, standard gelling agents (like Carbomer 940) may lose viscosity because extracts typically contain high levels of electrolytes. To achieve a clear, non-sticky, serum-like texture, I recommend the following electrolyte-resistant options:

1. Pro Polymer™ (Gel Maker)

This is highly recommended for a non-sticky feel. It is specifically designed to handle formulas with electrolytes (like your 20% extracts) without becoming liquid.

• Texture: Smooth, non-sticky, similar to high-molecular-weight Hyaluronic Acid.
• Usage Rate: 0.5% – 1.0% for a serum-like viscosity.
• Mixing: Can be mixed in the water phase (cold process). If the formula contains Glycerin, pre-mixing the powder with Glycerin first will help it disperse more easily.

2. Carbomer Ultrez 30 (Electrolyte Tolerance)

An excellent choice if you prioritize high clarity and ease of use. It is more resistant to electrolytes than traditional carbomers.

• Texture: Crystal clear, premium gel feel.
• Usage Rate: 0.3% – 0.8% for serum viscosity.
• Mixing: Sprinkle onto water; it self-wets and disperses quickly without high-speed stirring. Requires pH adjustment (e.g., with Triethanolamine) to form a gel.

3. Carbomer 2020 (EasyDisperse, Electrolyte Tolerance)

Suitable if you want a "Long-flow" texture, which gives the serum a slightly stretchy, luxurious feel.

• Texture: Clear, stretchy (long-flow), and smooth.
• Usage Rate: 0.5% – 1.0% for serum.
• Mixing: Easy to disperse in water. Requires pH adjustment to pH 6-7 to reach maximum viscosity.

Important Note on 20% Extracts:
Even though you mentioned "no salt," natural extracts are considered electrolytes in cosmetic chemistry. When using these polymers, it is best to create the gel base first, then gradually add the extracts. If the gel thins out after adding the extracts, you may need to slightly increase the percentage of the gelling polymer in your next batch.
