Ingredients focus: solutions for cleansing
Richard Scott – Editor, Personal Care
The need to cleanse has been a key function of personal care products for millennia, utilising natural saponins and exfoliators to rid the skin of dirt and grime. As understanding of disease- causing pathogens has developed, we have been able to measure ingredients’ impact on the ability of bacteria and viruses to survive in their presence. However, as has been brought into focus recently is the fact that many biocidal products also have a tendency to cause issues with dry skin, especially on hands. This requires formulators to balance effective sanitising with caring properties. Following is a selection of the latest
ingredients for cleansing formulations from leading global suppliers.
Ingredients for cleansing products Cola Lipid DCCA from Colonial Chemical is a plant-derived multifunctional phospholipid, combining gentle cleaning, mildness and excellent substantivity with broad spectrum antimicrobial activity. It can be utilised to minimise preservative requirements or to formulate self-preserved systems. Cola Lipid DCCA is compatible with all surfactant types and is ideal for use in personal care cleansers where mildness and antimicrobial properties are of importance. Cola Lipid DCCA’s multifunctional surfactant
behaviour offers broad spectrum antimicrobial activity and increases formulation bio-resistance. It is non-harmful to eyes and skin and is more stable than natural phospholipids, with broad pH tolerance and effectiveness. It also offers excellent substantivity on hair and skin and is synergistic with preservative systems and compatible with all surfactant types. It is recommended for use in baby wipes, hand sanitisers, body and foot scrubs, antiseptic wound cleansers, personal care cleansers and for boosting the killing properties of benzalkonium chloride and other sanitising quats. Corbion is increasing its capacity for
producing lactic acid in North America by around 40% to meet the growing demand for natural ingredients in multiple industries. Corbion also operates lactic acid production facilities in the Netherlands, Brazil, Spain and Thailand.
The use of lactic acid and its derivatives
as ingredients in foods and beverages for safe preservation, and in home and personal care products for effective but gentle disinfection and hygiene, has increased steadily in the

Americas over the past five years. Manufacturers of food, home and personal care products worldwide are finding the efficacy, consumer- friendliness and sustainability advantages offered by lactic acid-based solutions to be highly valuable in responding to multifaceted market pressures. Lactic acid, lactates and bio-based
emulsifiers are some of the most natural, safe, and cost-effective ingredients that formulators can use. Lactic acid and lactates are widely known for their moisturising, anti- ageing, sebum control, pH adjustment, and antimicrobial functions. Esterlac from Corbion is a range of natural
emulsifiers and surfactants which are mild, multi-functional, and safe. They bring many unique features in o/w and w/o emulsions as well as rinse-off applications. Esterlac emulsifers are very substantive
to proteins and starches. They improve the moisturisation and skin conditioning properties of formulations. Moisturising ingredients can penetrate into the skin more easily in the presence of Esterlac emulsifiers. On the skin, these ingredients provide a light, silky, soft feel, both in leave-on and rinse-off formulations. Furthermore, the Esterlac emulsifiers have a very low skin irritation: they are dermatologically innocuous and non-irritating to eyes. In bar soaps, shampoos and body washes,
Esterlac SLL acts like a foam booster and mild surfactant, delivering significantly improved foam volume and richness vs. formulations without Esterlac. Pentavitin, from DSM, is a 100% natural
bioactive, sustainably produced using sugar isomerization technology. By mimicking essential molecules found in skin’s NMF, this bioactive binds to the skin, locks in moisture, and is not washed off. Pentavitin, as supplied by DSM, does not contain preservatives, is Halal- certified and its ingredients are China-listed. It has one of the lowest carbon footprints in the industry for a moisturizing ingredient and is also NATRUE certified and approved by ECOCERT and COSMOS. The hydration benefits of Pentavitin have
already been proven to last for 72 hours after application in leave-on products. DSM has completed new studies which further demonstrate its benefits also in rinse-off applications such as shower gels and body
