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.

Photostability Test for Additional Sunscreen Claims, Part I: Protocol Setup

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.

SILAB Introduces Reconstructed Skin Models

SILAB Research has created SILABSKIN multi-layer reconstructed epidermis or skin models to test the efficacy of its natural cosmetic actives in vitro.

PCPC Responds to Breast Cancer Action's Ingredient Safety Allegations

The Personal Care Products Council has taken issue with the Breast Cancer Action’s latest statement alleging products offered to women in philanthropic cosmetic kits dispensed by the PCPC contain chemicals linked to increased cancer risk.

Yield Stress Measurements for Personal Care, Part I: Definitions and Basics

The aim of this article series is to properly define and differentiate yield stress from high viscosity, as well as develop a method for assessing whether a sample has a yield stress. In addition, it will illustrate how to determine the amount of yield needed for a given application.

Free Formaldehyde Preservative Stability in Personal Care: Part II—Formulations

As scrutiny of formaldehyde-donor (FD) and other preservative technologies has increased in recent years, additional assurances of the relative safety and benefits of FD technologies are required. This two-part article examines the effects of temperature and pH on free-formaldehyde levels (as detected by C-13 NMR), first in water, then in personal care formulations.

Free Formaldehyde Preservative Stability in Personal Care: Part I—Water

As scrutiny of formaldehyde-donor (FD) and other preservative technologies has increased in recent years, additional assurances of the relative safety and benefits of FD technologies are required. This two-part article examines the effects of temperature and pH on free-formaldehyde levels (as detected by C-13 NMR), first in water, then in personal care formulations.

Applied Neuroscience to Understand Cosmetic Consumers: Product Development (part III)

By measuring the non-conscious consumer response to products, concepts and before/after results, it is possible to make decisions for product development and marketing, as well as develop product claims. These possibilities are discussed in this three-part series, as are two case studies.

Applied Neuroscience to Understand Cosmetic Consumers: Consumer Study (part II)

By measuring the non-conscious consumer response to products, concepts and before/after results, it is possible to make decisions for product development and marketing, as well as develop product claims. These possibilities are discussed in this three-part series, as are two case studies.
