Isosorbide Dicaprylate: A Modulator of Biochemical Pathways Linked to Water and Barrier Homeostasis

Water homeostasis in the epidermis is essential for the normal function of the skin and for normal stratum corneum (SC) hydration. The discovery of the existence of the water-transporting protein aquaglyceroporin-3 (AQP3) in the viable epidermis and the presence of tight junction structures at the junction between the stratum granulosum and SC have brought new insights into the mechanisms of skin hydration, water distribution and barrier function.

Natural Lactic Acid From Corbion Promotes Low-Odor Moisturization

Purac UltraPure is a pure, natural lactic acid that brings moisturizing and anti-aging properties to formulations where a low base odor is required.

Biomimetic vs. Traditional Skin Moisturization: An In vivo Comparison*

To alleviate skin dryness, humectants and occlusive substances are traditionally used, mostly in combination. A third, relatively recent approach is biomimetic, i.e., active ingredients with lamellar structure containing skin-identical lipids. The aim of this study was to determine whether a biomimetic cream could deliver superior moisturization to human volunteers, compared with a conventional moisturizer containing petrolatum and mineral oil.

TRI-K Debuts Complex for Short- and Long-term Hydration

Fision Hydrate has been shown to reduce transepidermal water loss and increase barrier function.

Cleanse and Tone with BASF Ingredients

A beautiful complexion starts with a clean palette. BASF Care Creations offers ingredients for a wide range of cleansers, suitable for every skin type: foamy, gel cleansers for oily/combination skin; or creamy, emulsion-based cleansers for dry skin, as examples.

SYN-Coll: Power Anti-aging with a Collagen-boosting Peptide

Skin aging, in particular when induced by chronic UV exposure, leads to degenerative changes in the skin. Ultraviolet light also increases metalloproteinase activity. This leads to a breakdown of collagen at a higher rate than with just regular aging. If not taken care of, these fine lines become visible to others.

AAK Launches Clear Liquid Shea Oil for Moisturization

At in-cosmetics 2015 in Barcelona, AAK Personal Care will discuss its latest launch, a clear liquid shea oil that softens and moisturizes the skin.

Milk Protein for Increased Skin Hydration in Rinse-off Applications

TRI-K Industries added a milk protein to its NPNF (non-paraben, non-formaldehyde) line that increases skin hydration in rinse-off products.

A Brief Review of Polymer/Surfactant Interaction

In this article, the significance of parameters such as correlation length (blob size), micelle structure, comicellization, polymer adsorption conformation and coacervate structure are introduced with relevance to the conceptual appreciation of polymer-surfactant interactions and its bearing on recent advances in conditioning shampoos.

Penford Develops Biobased Conditioning Polymer for Skin and Hair

Penford Products, a division of Penford Corp., introduced a biobased deposition and conditioning polymer for personal care.

Evonik Launches Eco-friendly Hair Conditioning Agent

Evonik has launched a hair conditioning agent with an improved sustainability profile.

Lasting Hair Conditioning via In situ Controlled Flocculation

A new cationic homopolymer-based technology was designed to provide long-lasting conditioning to damaged hair without product buildup. Its mechanism, in situ controlled flocculation, is described here, and its capability to restore hydrophobicity to damaged hair is shown. Techniques are detailed for measuring silicone deposition, conditioning performance, hydrophobicity and buildup on hair.

Problems with Skin Protectants Part II, Theory and Perfluoropolyether Insights

Problems with skin protectants include unsatisfactory performance, poor prospects for improvement, and the lack of evaluation methods. Such problems were introduced in part 1 of this series. Here, theoretical aspects of skin protection and insights from perfluoropolyethers are discussed; concepts to push protectants to new efficacies will be covered in the final article of this series.

To produce a stable emulsion, an emulsifying agent can be added to the oil and water that will either act as a barrier to alter the droplet coalescence rate, or create an interfacial film that can produce repulsive electrical forces between approaching droplets.

Zeta Potential and Particle Size to Predict Emulsion Stability

Emulsions are popular vehicles in skin care due to their affinity for the skin; however, they are thermodynamically unstable systems. This study investigates zeta potential and particle size distribution as potential screening tools to predict instabilities in emulsion-based cosmetic products, to supplement regular accelerated stability testing.

Delivering Skin Moisturization from a Surfactant Cleanser

The instrumental and sensorial studies described here assess the ability of a test moisturizing product, at 1% in a surfactant system, to physically improve skin moisturization and structural condition, as well as provide a consumer-perceivable sensorial benefit. Changes in skin protein content, visible skin dryness, trans-epidermal water loss, corneometry and sensorial characteristics were measured and analyzed.

DSM Maps Facial TEWL/Hydration Among Varying Ethnicities

DSM Personal Care has partnered with the University of Limpopo, Newtone Technologies and AVR Consulting to run a study on facial hydration and barrier function in different ethnicities.

Clariant Introduces Sustainable African Oil for Hair and Skin

Clariant has introduced a multifunctional African hair oil that has benefit for both hair and skin. Plantasens Abyssinian Oil is a versatile oil that presents an opportunity for personal care formulators to combine natural product claims supporting radiant skin and lustrous, healthy hair for consumers.

Conditioning Damaged Hair Around the Globe

Although there is a demonstrated need for damaged hair products around the world, it can be challenging to formulate for different ethnic groups with their own unique hair characteristics. The need for a conditioning agent across ethnicities led Croda to develop a conditioning agent that is able to improve the appearance, feel and manageability of hair regardless of ethnic origin.
