Identification of external suppliers with libraries of functional natural and botanical derived compounds / extracts / products available for testing.

Background: An opportunity has been identified across BPC categories where consumers have an increasing preference for naturally derived formulations including those from botanical sources. It is desired to deliver functionality (antimicrobial, prebiotic, anti inflammatory etc) using natural or botanical derived products / extracts / actives. Currently there are limited libraries of functional natural compounds with the desired activity available at a cost-effective price and at relevant levels of production.

The goal of this project is to identify 3rd party suppliers who can provide materials for internal screening against relevant target endpoints. Materials with multiple functional properties are highly desired. Available materials will undergo appropriate screening at Unilever facilities against multiple end points and selected leads will be further investigated for safety and formulation compatibility in advance of potential progression to relevant clinical studies.

Materials may be used across personal care / cosmetics areas including skin care, scalp care, face care and oral care (some additional specific requirements for oral care actives).

Description:

• Natural materials or nature identical (primarily but not limited to botanical derived actives)
• Known activity for endpoints not limited to antimicrobial, anti inflammatory, anti oxidant, anti-biofilm.
• Preference for non colored materials however not essential.

Natural antioxidant(s) for improving storage stability of fragrances and actives prone to oxidation

Background:

Synthetic antioxidants such as Tinogard TT (Pentaerythrityl tetra-di-t-butly hydroxyhydrocinnamate) and Tinogard DA (didodecyl 3,3'-thiodipropionate) have been used as highly effective stabilizers to prevent degradation of actives sensitive to oxidation. They can mitigate negative impacts of oxidatively unstable actives on stability of final formulations. However, due to their synthetic nature, they are not suitable for use in natural Skin Care formulations. Some existing natural antioxidants such as tocopherol and rosemary extract come with strong odor or color profile, which introduced undesirable sensory attributes in final formulations. There is a need for natural alternative to TInogard TT and Tinogard DA antioxidants.

Description:

Natural antioxidant(s) for improving storage stability of fragrances and actives prone to oxidation. Natural antioxidant must be parity or superior in performance to Tinogard TT and Tinogard DA.

Desired Outcome (include preferred collaboration types here) :

Proof of principle studies versus Tinogard TT and Tinogard DA:

• GC headspace data after storage for benchmark actives: sunflower seed oil & CLA
• Color and chemical stability data after storage
• Rancimat test

What we aren’t interested in:

• Antioxidants with tox issue, registration issue, colour issue or odour issue
• Antioxidants that degrade during storage stability
• Antioxidants that act as potent antioxidants in skin but have poor efficacy in preventing actives from oxidation during formulation storage stability

Finding new ways to demonstrate product efficacy and discriminate between products

Background:

• The ability to accurately and reproducibly measure changes in physiological parameters of the skin is key to being able to demonstrate product benefits.
• Traditional measurement capabilities whilst robust and well-validated often do not allow for the discrimination of product effects.
• Non-invasive measurements allow greater chances of inclusion in a clinical setting
• Measurement of skin ageing and of disrupted epidermal skin health (e.g. dryness, sensitivity etc) are of particular interest.

Description:

• The ability to make more detailed and discriminatory measurements – or more discriminatory analysis from existing measurements – would provide increased scope for testing in open settings
• The non-invasive collection and analysis of biomarkers would be considered
• Relevant measurements which can be related to parameters of skin physiology and product usage are sought.

Desired Outcome (include preferred collaboration types here) :

• Provision of novel measurement capabilities which allow the demonstration of product efficacy and product discrimination.
• Improved analytical methods, that can demonstrate product benefit, using data generated with current instruments (Visia, primos, cutometer, TWEL etc..) deployed in skin clinical studies.
• Ideally non-invasive measurements
• Transferrable capabilities which could be implemented in clinical settings i.e. does not rely on panellists attending a dedicated facility
• Meaningful measurements/analysis which can be related to skin physiology and benefit areas.

What we aren’t interested in :

• Invasive techniques
• Non-discriminating measurements
• Non-transferrable measurements which cannot be deployed at non-core facilities.
• Measurements we already use
• Measurements which cannot be related to skin physiology
