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.

Clean and Green: A Review of Modern Day Surfactants and Emulsifiers

Many certified organic shampoos and body washes use soaps such as potassium cocoate as their primary cleansing agent, partially due to a lack of suitable, organically approved foaming alternatives. This article reviews the use of modern surfactants and emulsifiers developed based on a green and eco-conscious philosophy.

Coffea bengalensis for Antiwrinkle and Skin Toning Applications

Coffea species have been widely evaluated for effects including oxidative stress protection and immunomodulation. The present study therefore evaluates the cosmetic activity of an extract obtained from cultured Coffea bengalensis stem cells. Results showed the extract imparted hydration activity in the keratinocytes, stimulated collagen synthesis in the fibroblasts and enhanced adipocyte differentiation starting from mesenchymal precursor cells.

Lightening and Illuminating Skin With Acetylated Hydroxystilbenes From Rheum rhaponticum

Skin discoloration and excessive pigmentation due to increased melanin production is associated with skin inflammation and aging. Therefore, an extract rich in acetylated hydroxystilbenes from Rheum rhaponticum was combined with panthenyl triacetate to test in the melanogenesis pathway. The complex strongly reduced melanogenesis and melanin accumulation in human skin explants, decreased melanin content in pigmented spots, increased skin brightness and enhanced skin radiance on the face of human volunteers in a double-blind clinical study.

A Sunscreen Formulation for Acne-prone Skin

This article describes the study of a topical sunscreen formulation that contains titanium dioxide and ethylhexyl methoxycinnamate for UV protection, and phosphatidylcholine and hydrosoluble azelaic acid for acne control.

Hyperbranched Polyalphaolefins Enhance Anhydrous Stick Formulations

Hyperbranched polyalphaolefins offer distinctive functional and aesthetic properties due to their branch-on-branch configuration. In anhydrous stick formulations containing polyethylene or other crystalline waxes, the addition of hyperbranched polyalphaolefins is shown in this article to lower pour points by as much as 10C, increase gloss, modify structure and improve formula stability.
