A lotion is a topical preparation typically used for application or cleansing of the skin or mouth. It is usually a liquid or semi-solid lotion consisting of an aqueous phase and an oil phase. Lotions are formed by mixing these two phases together with the help of emulsifiers and other ingredients.

Protheragen-ING provides a professional and comprehensive one-stop service for lotion formulation. Our team consists of experienced and skilled professionals, including chemical engineers, pharmacologists and formulators. With a wide range of knowledge and skills, they are able to provide customized development services according to customers' needs and requirements and are dedicated to helping you create high-quality and innovative lotion formulations that meet your specific requirements.

Cases of Common Lotion Formulations

Lotion can be used as a vehicle for topical delivery of medications to the skin. These are often referred to as topical drugs or topical medications. Topical lotions can be formulated to contain active pharmaceutical ingredients (APIs) that are intended to treat specific skin conditions or provide localized therapeutic effects. Some examples of lotion drugs include:

Comprehensive Lotion Formulation Development Services

Our lotion formulation development services involve the process of creating stable and effective lotion formulations with desired properties. The following are the key steps:

• Define objectives: Clearly define the objectives and requirements of the lotion formulation. Consider factors such as intended use, target market, desired texture, sensory attributes, stability requirements, and regulatory guidelines.
• Ingredient Selection: Select the appropriate ingredients based on the desired properties of the lotion. Common ingredients in lotions include water, oil, emulsifiers, thickeners, humectants, preservatives, fragrances, and active ingredients. Consider the compatibility, stability, safety, and performance of each ingredient.
• Lotion Systems: Lotions are typically oil-in-water (O/W) lotions. Determine the appropriate emulsifier system and ratio to obtain a stable lotion.
• Active Ingredients: If lotion formulations contain active ingredients (such as vitamins, plant extracts, or sunscreens), we ensure their compatibility with other ingredients and their stability throughout the product's shelf life.
• Texture and rheology: Determine the desired texture and rheological properties of the lotion, including its thickness, spreadability, viscosity, and, absorption rate. Thickeners, viscosity modifiers, or emollients can also be added to achieve the desired consistency.
• Stability testing: We can perform a variety of stability tests to ensure that formulations remain stable under a variety of conditions, such as temperature changes, light exposure and microbial contamination.
• Sensory evaluation: We evaluate the sensory attributes of lotions, including appearance, color, odor, and skin feel.
• Safety and regulatory compliance: We ensure that lotion formulations meet safety standards and regulatory requirements in target markets. Consider ingredient restrictions, labeling requirements, and any specific regulations related to claims or active ingredients.
• Quality control: We help establish quality control procedures to monitor the consistency and quality of lotions during production. This may include testing for pH, viscosity, microbial contamination, and other relevant parameters.
