In vivo Delivery Confirmation: Measuring the Deposition of Salicylic Acid from Anti-acne Face Wash

Measuring the delivery of active ingredients is an important part of the product development process, and particularly desirable are non-invasive, in vivo methods. This work describes the use of fluorescence excitation emission matrices in vivo to measure the deposition of salicylic acid from anti-acne face wash products.

Wet Skin Factor for Sunscreens: An In vitro Method, Part II

Sunscreens designed for application to wet skin are popular in part due to convenience, skipping the drying step completely. In relation, these authors propose a new in vitro test to compare the wet skin factor of sun care products. Here, 20 products were tested and compared according to several conditions in order to define the best parameters for the method.

Heat Protection Getting Warmer: Specialty Silicones for Hair

The present study examines the ability of silicones to protect hair during heat styling, compared with other industry benchmarks and untreated hair. Also discussed are the mechanisms through which different silicones contribute heat protection in hair care products such as leave-in conditioners, serums and other product forms.

Nonreactive Paths to Internal Changes: Modifying Hair’s Structure from the Inside, Part 2

Scientific evidence suggests that nonreactive compounds have the ability to modify hair’s structure, providing formulators additional ways to craft products and worry less about hair damage.

VIDEO: P&G Scientists on Claims Substantiation in Anti-dandruff Care

Head & Shoulders recruits an army to prove the benefits its brand delivers to consumers. Hear more in this video.

How to Prove 'Rub-resistant' Sun Protection

Today’s consumers desire sunscreens that are not only more effective against UV radiation, but also provide water, sand, sweat and rub resistance. These authors propose a new in vitro test to assess and compare rub resistance factors, which they illustrate here by testing 20 sun care products.

Modifying Hair’s Structure From the Inside

Changing hair properties is a regular function of daily-use treatments. But what other methods can be used? Altering the hair’s internal structure may be the next way to achieve these changes.

Silab’s Mitokinyl Battles Urban Pollution

Silab has introduced Mitokinyl, an anti-pollution natural active ingredient, which fights damaging environmental stressers.

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?

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.
