Treating Wrinkles with Dimethylaminoethanol, Retinol and Mineral Salts

A placebo-controlled study was conducted to determine if the appearance of wrinkles on facial skin could be improved by a combination of three cosmetic ingredients: dimethylaminoethanol, retinol and mineral salts. Both clinical assessment and video analysis of cutaneous replicas showed a significant improvement of the wrinkle appearance.

An Aquaporin-inspired Lipid Concentrate for Mature Skin

The authors describe a novel multi-lamellar concentrate based on ceramide technology and newly identified cell-signalling molecules. This skin-identical blend provides skin protection benefits and is shown to increase molecular markers for water management and barrier components that decline during aging, thus improving skin barrier function, moisturization and elasticity.

Xiameter Introduces Paraben-free Silicone Hair Conditioner

Dow Corning has added a paraben-free silicone emulsion for hair conditioning to its Xiameter brand offerings.

Induchem Activates Opioid Receptors for Anti-aging

Induchem has created an anti-aging active that maintains and activates opioid receptors in the skin to regulate cell differentiation, migration and proliferation.

Formulating for Electrolyte Resistance in Conjunction with Sensory Appeal

Skin care formulations often are enriched with high levels of electrolytic ingredients for various skin benefits. However, these have a negative impact on the viscosity, texture and stability of a system. Described in this article is a multifunctional polymer that is designed to provide excellent electrolyte resistance along with a pleasant sensory profile, as will be shown.

Evidence for Moisturizer Efficacy

Moisturizers are used on all skin types to address a range of skin issues/needs. Main uses include: prevention in normal and dry skin, healing of irritated skin and treatment of diseased skin. It is difficult to clinically study the efficacy of moisturizers in a meaningful way.

TFChem's Skin Lighteners Found Non-sensitizing

Sirona Biochem Corp. has announced that the skin lightening compounds manufactured by its subsidiary TFChem, TF-849 and TFC-723, were found not to be skin sensitizers.

CSIRO and Larissa Bright Mimic Coral Protection for Broad-spectrum UV Filters

CSIRO, in partnership with skin care company Larissa Bright Australia, has created UVA/UVB sunscreen filters that mimic the natural sun protection used by corals on the Great Barrier Reef.

Natural Preservation from Concepts in Nature

Chemical defense mechanisms used in the plant kingdom are the basis of natural antimicrobials with multifunctionality for preservation of cosmetic formulations. Two examples are organic acids and glyceryl monoesters.

Hair and Amino Acids

Amino acids are taken up by hair and assist in improving hair surface hydrophobicity, tensile strength and luster. This article discusses interactions between amino acids and hair.

Polyquaternium-74: An Advanced Hair Conditioning Polymer

Polyquaternium-74 is a synthetic high performance conditioning polymer whose flocculation and deposition characteristics enable it to match or outperform traditional conditioning polymers in detangling, overall hair conditioning, shine enhancement and buildup reduction when combined, as shown here, with a submicron dimethicone emulsion. Benefits are noted for 2-in-1 shampoo formulations.

Formulating with Naturals—Anti-aging Actives

To provide consumers an anti-aging benefit, finished products and ingredients must ameliorate both firmness and lines and wrinkles. The loss of firmness, attributed primarily to the loss of underlying dermal support, is both a sign of skin aging and a cause of most lines and wrinkles. Thus, improving this underlying matrix to enhance skin’s appearance should be a key feature of anti-aging product performance.
