Researchers Report Anti-acne Effects in Resveratrol

Researchers at the University of California have reported that resveratrol inhibits acne growth and boosts the antibacterial effect when combined with benzoyl peroxide.

Are Silicones Safe and Sustainable? What are the Alternatives?

Alternative hydrocarbons, esters, ethers and emollients aim to replace D5, and to a lesser extent, low viscosity silicone fluids—and many of them meet the mark. However, a second look at why silicones are being replaced is advised. Formulators may want to evaluate the data themselves for both safety and environmental aspects to make their own judgments.

Lipotec Introduces Anti-cellulite Active with Night Action

Lipotec, a Lubrizol company, has introduced an active that fights cellulite at night.

Facial Cleansing with Mild Surfactants

Cleanser technology has come a long way from a “cleansing only” concept to one that includes other benefits such as moisturization, and marketing efforts have focused on these additional ingredients and claims.

Lightening Skin Through a Melanogenesis-interrupting Peptide

Cutaneous pigmentation is determined by melanogenesis, the transfer of melanosomes to keratinocytes, and the distribution of melanin to skin, among other processes. Interrupting these would limit skin pigmentation to achieve a better skin lightening effect. Here, the authors review the biological mechanisms of melanin production, then test a peptide designed to act on them for a lightening effect.

Greentech Launches Soft Butter Line for Sensory, Emulsification and Skin Benefit

Greentech has launched a range of 3-in-1 actives that emulsify, consistute the oily phase and improve biological activity. GreenSofts combine the properties of soft butters with sensory and auto-emulsion capacities.

Lysine Polypeptides for Dandruff Treatment

Dandruff remains a significant yet poorly served chronic scalp disorder for which more effective treatments are required. Here, lysine polypeptides are demonstrated in vitro and in vivo to effectively address the causative organism in dandruff, Malassezia spp., and provide a potential basis for new treatments to counteract this condition.

Photoprotection of TiO2 Using Propenoic Acid Esters

Titanium dioxide (TiO2) is known to be photocatalytically active. Even with surface modifications, it catalyzes the decomposition of organic materials and promotes the formation of reactive oxygen species. However, a particular propenoic acid ester is shown here to protect TiO2 from inducing such reactions, making it a more effective and safer UV filter.

Sustainable Ingredient Science: Fossilized Coral Powder

Coral powder has applications in cosmetics but its use has impacted the marine environment. Fossilized coral could provide a sustainable alternative for uses such as fillers, cleansing and whitening agents, astringents, sebum absorbers, or to supply trace minerals to skin. Its use as an exfoliant it particularly noteworthy as formulators seek natural alternatives to polyethylene beads.

Lonza Debuts Multifunctional Ester for Conditioning and Dry Feel

Lonza has launched an ester that conditions skin, has good spreadability and leaves a dry, powdery after feel.
