Surfactants are of widespread importance in the detergent industry as well as in the cosmetic industry. Additionally they are used for lubrication, catalysis, and in drug delivery.

For any living organism, presence of water at the sites where it is essential for normal functioning is crucial for survival. The outer layer of the skin provides a typical example of the human body preserving water at an essential site (in close proximity to a dry environment). It is therefore understandable that control of the presence of water is one of the fundamental properties of the skin.

Alternative preservation is becoming more and more popular, and many products that claim to be “preservative free” or “free of synthetic preservatives”, “paraben free” etc are on the market.

In order to maximise efficacy in sunscreen formulations, it is desirable to have sunscreen actives which are photo-stable. It is known that certain organic UV filters are subject to photo-degradation,1-5 and therefore the development of technologies to improve the photo-stability of these filters has been the subject of much research in recent years.1,6

The human skin is a vital organ with many functions, the most important being to protect the body against undesired influences from the environment. In order to maintain this barrier function, the skin should stay in a healthy condition.

Titanium dioxide is often added to sun care formulations to complement organic UV filters and boost the SPF value, particularly when trying to achieve an SPF of 30 or higher.

Many of the exhibitors at in-cosmetics Asia in Bangkok (4 – 6 November) will be demonstrating how the scope of what is achievable with formulations continues to be increased.

Naturals will be to the fore, and promoted will be high performance botanical extracts for sunscreen and whitening cosmetics and superior botanical emollients.

Key trends, issues and challenges facing personal care product formulators in the Asia Pacific region will be explored during a comprehensive education programme featured at the forthcoming in-cosmetics Asia show in Bangkok, Thailand (4-6 November 2008).

Mitochondria play a central role in metabolism and bioenergetics, and their main macromolecular structures have been determined down to the atomic level.

However, the study of mitochondria is far from exhausted. Recent understanding of the essential role of mitochondria in the ageing process has raised considerable interest in a new anti-ageing approach that involves the development of new target molecules to protect against mitochondrial ageing and dysfunction.

Natural, organic, botanical, sustainable, green chemistry… these words reflect the market trend of the cosmetics industry towards “greenness”. For more than 20 years, Silab has developed and manufactured natural active ingredients for the cosmetics industry.

Natural cosmetic ingredients have shown tremendous growth in recent years, and studies have been conducted on botanical extracts for cosmetic use. Several aspects should be considered when utilising botanical materials in cosmetics – such as the quality of the plant materials, processes, biological activity, and safety.

Injectable agents, such as collagen, have been used for some time to provide longlasting lip enhancement, but this method is invasive and relatively expensive.

This is the second in a series of articles which gives an introduction into the science and technology of cosmetic products intended to colour the hair. This part deals with the basic structure of hair, how it is damaged and some basic aspects of how hair interacts with the molecules that can colour the hair. The first article in the series, reviewing the history of hair colouring, was published in the July 2008 edition of Personal Care Asia Pacific.

Less than two decades ago, the cosmetics industry in India was relatively local – with simple, largely undifferentiated formulations and, barring a couple of entrenched multinational corporations, just a few global brands representing a miniscule share at the premium end of the market through imports of fullypackaged stock keeping units (SKUs).

A wide range of topics will be examined during Innovations Seminars lined up for in-cosmetics India, which is being held in Mumbai on 17 and 18 September 2008.

Those attending the seminars will be able to interact with experts who are directly responsible for conducting new scientific research and who will be sharing their specialist knowledge. The development of concepts, and ensuing commercial opportunities, will be explored.

A free-to-attend Beauty Innovation Seminar will be staged on 17 September (14.00 – 14.45) with the title ‘How Eastern traditions are inspiring today’s beauty’. The presenter will be Ian Wilson of Mintel.

The personal care industry represents a more than US$300 billion worldwide market. As the global consumer becomes savvier through exposure to electronic media and advertising, the burden of proof for product claims is raised for new entrants to the market or for new formulations of existing products.

If skin aged counter-clockwise when people turned 35 years, not only would consumers select their cosmetic products differently but also the whole cosmetic industry would have to offer completely different product categories. Of course this is just an attractive idea. Ageing proceeds in one direction and the skin unfortunately often shows the most obvious signs of ageing. The major telltale signs are reduced elasticity, poorer structure and appearance of wrinkles. Reduced turnover of skin cells and exposure to environmental factors (such as UV light), speeding up the process of skin ageing, are essential causes.

Personal care formulations can vary enormously in complexity from relatively simple mixtures of a few components in a single phase, to multiple component systems based on mixtures of hydrophilic and hydrophobic ingredients in emulsions or suspensions.

The personal care industry represents a more than US$300 billion worldwide market. As the global consumer becomes savvier through exposure to electronic media and advertising, the burden of proof for product claims is raised for new entrants to the market or for new formulations of existing products. Unsubstantiated product claims and consumer suspicion influence buying decisions and drive the need for demonstrable proof of proper product selection and performance. At the same time, with advancements in cellular and molecular biology, an exciting new generation of products with novel anti-ageing, anti-wrinkle, clarifying, and beautifying elements are emerging. Unfortunately, many of these formulations are coming under scrutiny from skeptical consumers who are eager to see scientific data to support whether the product will work for them personally.
