Research Direction of Low-Allergen Formula ultrasound gel for Enhancing Patient Comfort: Pingchuang Medical

Jun. 09, 2025

Comfort during ultrasound examinations is an indispensable factor. In addition to the tension that the examination itself may bring, any discomfort caused by the ultrasound gel directly applied to the skin, such as irritation, itching, allergic reactions, or a cold sensation, can reduce the patient's willingness to cooperate and the overall medical experience.

Therefore, developing coupling agent formulas with lower allergenicity and a gentler skin feel has become an important direction for improving patient comfort. Pingchuang Medical Group is committed to patient experience and considers the development of low-allergen formulas as one of the important directions in its ultrasound gel product line.

 

The core of developing hypoallergenic formulas lies in minimizing or avoiding the use of known or potential irritant and allergenic ingredients. The research and development team of Pingchuang Medical follows the "subtractive principle" and the "optimal selection principle" in formula design. Firstly, it is as far as possible to avoid using common allergens, such as certain specific preservatives (such as parabens like hydroxybenzoic acid esters, methylisothiazolinone MIT, etc.), fragrances, pigments, and propylene glycol that may cause discomfort to some people.

 

Secondly, when selecting necessary ingredients (such as thickeners, moisturizers, pH regulators, etc.), priority is given to those that have been widely verified, recognized for their high safety, and low irritability, such as medical-grade or cosmetic-grade raw materials. For example, high-purity polymers with better biocompatibility are chosen as thickeners; glycerin and other classic and gentle moisturizers are used; and a preservation system with lower irritability is adopted. The selection of raw material suppliers is also very strict, ensuring reliable source and low impurity content.

The control of pH value is also crucial for reducing irritation. The natural pH value of the skin surface is weakly acidic (usually between 4.5-6.5). The hypoallergenic formulas of Pingchuang Medical precisely control the final pH value of the product to make it as close as possible to the physiological pH range of the skin, avoiding irritation to the skin due to over-acidity or over-alakalinity.

 

In addition to chemical irritation, physical irritation (such as temperature) can also affect comfort. Traditional coupling agents may have a cold feeling when applied, especially in winter or for patients sensitive to temperature. Pingchuang Medical is also focusing on and exploring technologies to reduce this cold feeling, such as whether the thermal conductivity of the formula can be optimized to reduce it, or whether it is possible to explore the possibility of using a constant temperature heater in conjunction.

 

In order to verify the actual effectiveness of the hypoallergenic formula, Pingchuang Medical will conduct the necessary safety assessment. This may include internal patch test evaluations or entrust professional third-party institutions to conduct more stringent skin irritation tests and repetitive insult patch tests (RIPT) to objectively demonstrate the hypoallergenic and gentle nature of the product.

Pingchuang Medical can also provide further hypoallergenic customization according to customer needs. For example, develop alternative formulas that completely do not contain the specific component for patients known to be allergic to it; or develop "minimalist formulas" that only contain a very few essential ingredients.

 

Enhancing patient comfort is an embodiment of the humanization of modern medical services. By researching and promoting hypoallergenic formula ultrasound gel, Pingchuang Medical aims to reduce the discomfort that may be caused by ultrasound examinations, allowing patients to receive the examination more relaxed and comfortable. This not only helps to improve patient satisfaction but may also indirectly improve the quality of the examination due to better patient cooperation.
