Sederma Ensures Baby Product Friendliness with Ingredient Testing

To ensure quality and safety for baby care products, Sederma performed required toxicological tests on four active ingredients.

New Sunscreen Allows Body to Produce Vitamin D

Researchers discovered altering ingredients in sunscreens allows the body to produce vitamin D, which led to a new sunscreen development called Solar D.

Coiffed Conundrum: Equating the Measurement of Hair Shine

Shine constitutes the ability for light to reflect off of surfaces. For consumers, perceived shine is indicative of healthy hair. For marketers, it is the gateway to hair product benefits claims. But how can shine be measured to support those claims?

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.

Ashland’s Ingredients Portfolio Advances Worldwide

Ashland integrated its research and development facilities across the world to measure the performance of its ingredients portfolio based on consumer populations in major markets.

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.

Animal Testing's in the Hot Seat in Korea

Activists for alternatives to animal testing and industry groups hosted a forum to pressure Korea's lawmakers to prioritize investment in new approaches to cosmetics safety testing.

Matmarine Blue Ingredient Leaves Matte Finish

To help produce a product leaving a matte finish to last the whole day, 2% of Lipotec’s Matmarine blue ingredient (INCI: Pseudoalteromonas Ferment Extract) was applied to a BB cream.

Photostability Test for Additional Sunscreen Claims, Part III: New Claim

Proposed here is an in vitro method, based on UV transmission measurements at two irradiation doses, to test and rank sunscreens based on their photostabilities. This approach was used to assess some 107 sunscreens and shows how, by strictly controlling key parameters, comparisons between the photostabilities of products can be made, with potential for new label claims.

Photostability Test for Additional Sunscreen Claims, Part II: Calculations and Results

Proposed here is an in vitro method, based on UV transmission measurements at two irradiation doses, to test and rank sunscreens based on their photostabilities. This approach was used to assess some 107 sunscreens and shows how, by strictly controlling key parameters, comparisons between the photostabilities of products can be made, with potential for new label claims.
