Laboratory instruments for cosmetics optimisation

Laboratory instruments for cosmetics play a crucial role in product formulation and quality control. Anton Paar provides state-of-the-art tools such as Rheometers and Viscometers, assisting manufacturers in research, development, and testing of personal care products.

What makes a consumer prefer one shampoo, skin cream, or mascara from the many thousands on offer? What criteria can be used to assess a product’s properties – and how does this impact product development and improvement?

The answer to these and other questions may begin with:

• looking at the properties of the raw materials used
• the ratios required
• how the final product looks and behaves in the container, in storage, and during use.

Measuring parameters such as density, refractive index and concentration as well as characterising the flow behaviour delivers excellent values. This data gathered from laboratory instruments for cosmetics can be used in subsequent steps to evaluate, optimise, and modify products – as well as in their quality control.

Versatile instruments for cosmetics development

A rheometer is a powerful laboratory instrument for cosmetics to investigate formulations, whether you are:

• optimising the flow of a body lotion
• determining the absorption time of a cream on skin
• assessing how much foam a shampoo produces and for how long
• discovering how to improve the feel of a lipstick.

Anton Paar’s renowned MCR Rheometers have a test to give the right insights. Rheometers also help you assess and improve a product’s behaviour in storage (sedimentation, discolouration) and a special powder cell allows you to optimise the flow of powders.

The Anton Paar ViscoQC rotational viscometer is used for fast and accurate quality control and routine analysis.

The ViscoQC series, including models like the ViscoQC 100 and ViscoQC 300, offers single-point and multi-point viscosity measurements, respectively. These instruments feature automatic spindle recognition (Toolmaster™), magnetic coupling for easy spindle exchange, and digital levelling to ensure accurate and repeatable results. The ViscoQC 300 also supports compliance with 21 CFR Part 11, GMP, and GAMP 5 standards, making it suitable for regulated environments.

The ViscoQC series is purpose-built for reliable and accurate viscosity measurements in routine quality control, offering user-friendly operation and robust performance. For customers requiring additional rheological insights, such as thixotropic behaviour, Anton Paar offers the MCR series of Rheometers, which complement the capabilities of ViscoQC.

Monitoring the production of hydrogen peroxide

With the inline density sensor L-Dens 7400, you can monitor the concentration of H₂O₂ during hair care product manufacturing. This sensor ensures continuous and highly reliable measurement of hydrogen peroxide in the concentration range from 0% to 95% and at temperatures up to 100°C.
