Clear Gel Thickeners for Water-Based Formulations
คำถาม
What substances can be used to thicken water into a clear, syrup-like gel? Please recommend clear gel thickeners for water-based formulations and explain factors to consider for selection, such as compatibility with formula type, electrolytes, and pH. Specifically, I am interested in options like:
- Pro Polymer
- Xanthan Gum
- Carbomer
- Hydroxypropyl Methylcellulose
- Hydroxyethyl Cellulose

Clear Gel Thickeners for Water
To make water thick and clear like syrup, you can use several types of thickeners. The choice depends on the specific requirements of your formulation, such as desired viscosity, compatibility with other ingredients (like electrolytes or acidic/alkaline substances), and ease of use.
Here are some common thickeners that can provide a clear gel texture:
- Xanthan Gum: This is a natural thickener that can create a clear gel. Different grades offer varying textures, from smooth to more stretchy. It is generally compatible with electrolytes.
- Pro Polymer™: This gel maker creates a clear gel with a polymeric structure. It is known for good electrolyte resistance and can create a range of textures, including a creamy pudding-like consistency at higher concentrations.
- Carbomer: Carbomers are synthetic polymers that form clear gels when neutralized with an alkali. However, they are generally sensitive to electrolytes and low pH (acidic conditions), which can reduce their thickening ability or cause the gel to break.
- Hydroxypropyl Methylcellulose (HPMC): HPMC is a non-ionic cellulose ether that forms a clear gel. It is suitable for formulations containing electrolytes and can also help create foam in cleansing products.
- Hydroxyethyl Cellulose (HEC): Similar to HPMC, HEC is also a non-ionic cellulose ether that creates a clear gel and is suitable for formulations with electrolytes.
When selecting a thickener, consider the pH of your formula and whether it contains electrolytes. Xanthan Gum, Pro Polymer™, HPMC, and HEC are more tolerant of electrolytes compared to Carbomer. Always check the specific product details and recommended usage rates to achieve the desired clear and viscous texture.
