Analysis of Your Aloe Vera Gel Formula

Thank you for sharing your aloe vera gel formula. Let's break down the ingredients and percentages you used:

• Pro Polymer™ (Gel Maker): You used 5% Pro Polymer. Based on the product description (Product ID 234), using high amounts (>3%) of Pro Polymer is expected to create a thick, creamy, pudding-like texture, which matches your observation. If you prefer a less thick gel, you would need to reduce the percentage of Pro Polymer.

• Aloe Vera Extract (extraction ratio 10:1 FullAssay™): You used 20 grams, which is 20% of your 100-gram formula. The recommended usage rate for this specific extract (Product ID 76) is 1-10%. While 20% is higher than the typical recommendation, it might be used for a higher perceived concentration of aloe vera. However, this extract is listed as being preserved with Phenoxyethanol 0.5%.

• Natural Bisabolol (Brazil Chamomile): You used 3 grams, which is 3% of your formula. The recommended usage rate for this ingredient (Product ID 78), which contains natural Bisabolol from German Chamomile, is 0.5-1% (1% is recommended). Your usage is higher than recommended. This ingredient is also listed as being preserved with Phenoxyethanol 0.8%.

• น้ำกลั่นใบย่านาง (Yanang leaf distilled water): Information on this specific ingredient is not available in our product database. For cosmetic formulations, purified water (like Product ID 838) or known hydrosols (like Chamomile Water, Product ID 1308) are commonly used as the water base.

Important Consideration: Preservatives

You mentioned that you are allergic to preservatives and did not add any to your formula. However, based on the product descriptions for the specific Aloe Vera Extract (ID 76) and Natural Bisabolol (ID 78) found in the search, both of these ingredients contain Phenoxyethanol as a preservative.

Using these ingredients means your formula does contain a preservative, specifically Phenoxyethanol, which you stated you are allergic to. If avoiding all preservatives is critical due to an allergy, you would need to find preservative-free versions of these extracts (which are less common and have shorter shelf lives) or use alternative ingredients.

Furthermore, creating a water-based product like a gel without any effective preservation system is highly risky. Water is a breeding ground for bacteria, mold, and yeast. An unpreserved or inadequately preserved product can become contaminated very quickly, leading to spoilage, changes in texture/smell, and potentially causing skin infections or irritation. For safety and product stability, especially in a product that will be stored and used over time, a proper preservation system is essential.

If you have a severe allergy to common preservatives like Phenoxyethanol, it is crucial to source ingredients that are certified preservative-free or consult with a formulator experienced in creating products for severe allergies. However, please be aware that preservative-free water-based products require very strict manufacturing conditions and typically have a very short shelf life, often requiring refrigeration.

In summary, your formula uses higher percentages of Pro Polymer, Aloe Vera Extract, and Bisabolol than typically recommended. More importantly, the specific extracts you likely used contain Phenoxyethanol, contradicting your goal of a preservative-free product and posing a risk given your allergy. Creating a truly preservative-free and safe water-based gel for general use is challenging due to microbial contamination risks.
