Symrise’s Thermolat Reveals Warming Test Results

“Thanks to its safe and gentle effect, Thermolat can be used in a very wide range of care and beauty products and gives them the ability to create a cozy warm feeling.”

Micelle Mash-up: Study Explores Surfactant vs. Fragrance Partitioning

What happens to the fragrance when you swap out one surfactant in a composition for another? That's what researchers at Firmenich wanted to find out; a newly published study explains.

Sensory Insight: Emollient Profiling Accelerates Speed to Market

Sensory science allows cosmetic chemists to evaluate formulas by providing objective and scientific data on the sensory properties raw materials impart in formulations. This article describes a new sensory test called “Oil Sensory Qualification,” which provides formulators with a fast approach to emollient selection using sensory science.

Reaching a Zen-like State in Skin: Biomimetic Peptide to Balance Sensitivity

Inspired by nature, biomimetic peptides are potent allies in skin care. This paper identifies palmitoyl tripeptide-8 as an effective modulator of neurogenic inflammation and provides clinical evidence of its protective and soothing activities in sensitized skin.

How Damaged is Hair? Part I: Surface Damage

This article is the first of two that explores ways of capturing and quantifying the different forms of hair damage. Here, we begin with damage to the hair surface, or cuticle, while also exploring the implications of this occurrence. A second article will focus on damage to the internal cortex structure.

The Perplexing Topic of Hair 'Type': How Do We Classify Hair?

Most hair-related properties and issues can be rationalized by fiber size and shape, and/or the consequences of extreme conditions. However, the varying reactivity of different hair types with chemical treatments suggests potential differences in structure.

'Zapping' Sensitive Skin: Capsaicin Tests Show Embelia concinna Comforts Irritation

In previous work, a flavonoid-titrated active ingredient based on Embelia concinna was shown in vitro to calm and soothe sensory neurons stimulated with capsaicin. Here, those results are confirmed in vivo using a capsaicin stinging test with human volunteers.

Ranking Body Creams by Sensory Properties

Ranking descriptive analysis (RDA) is a sensory test from the foods industry. Here, it is applied to evaluate the properties of four body creams, and the results are compared with those of the well-known quantitative descriptive analysis (QDA) profiling. Findings suggest this technique could positively impact sensory testing for product development.

Yield Stress Measurements for Personal Care Part II: Methods

The previous article defined yield stress and explained how to calculate the amount needed for a given application. Here, methods for measuring yield stress are compared by determining the values of two materials: a non-thixotropic acrylates copolymer solution, and a thixotropic body wash. The results provide recommendations for methods in terms of relevance, exactness and robustness.

Lucas Meyer Measures Consumer Response to Phospholipid Emulsifier

A study conducted by Lucas Meyer revealed that its phospholipid emulsifiers were capable of invoking positive emotion.

Testing and Developing a Sugar-derived Surfactant Blend for Delicate Skin

Vegetable-derived, mild and sustainable skin cleansing ingredients are in demand, and this has led to the development of new detergent structures. Described here is a combination of two mild surfactants that fulfils these requirements using the concept of “interrupted soap” to impart mildness. Studies to verify the functional, sensorial and mild characteristics of the new blend are detailed.

Measuring and Pre-selecting Functional Filler Pigments

Functional filler pigments play an important role in adjusting optical properties such as transparency and soft focus effects in cosmetics. However, their suitability for specific formulas is not apparent until time-consuming tests using many different fillers have been conducted. Therefore, a new method to predetermine the soft focus effects of functional filler pigments is described here.
