The invention includes a method of increasing the substantivity of a personal care composition to hair, skin or nails by preparing a composition of an aqueous phase, a non-aqueous phase and a neutralized amino acid ester that is a reaction product of a neutral amino acid having a non-polar side chain with a long chain fatty alcohol and is represented by formula (I): ##STR00001##
wherein R.sup.1 is an alkyl group; R.sup.2 is a linear or branched carbon chain; and the amine group of the amino acid is neutralized with an acid. The composition is substantially free of petrochemicals and/or derivatives of petrochemical materials. The aqueous phase and the non-aqueous phase are emulsified by the neutralized amino acid ester. Other methods and an emulsifiers that is the neutralized amino acid ester are included. Because the neutralized amino acid ester and the compositions do not contain petrochemical-derived ingredient, the products are natural.

Disclosed are propolis products suitable for use in various industries such as food, health and cosmetics where propolis, which promote various beneficial biological activities in addition to having antimicrobial, antifungal, antiviral, anti-inflammatory, anti-cancer and anesthetic affects, is extracted correctly to offer it a form suitable for human consumption and with the highest bioavailability, where it is fast and easy to consume. Also disclosed is a method of production thereof.

A compound based on 1-Aza-3,7-dioxabicyclo[3.3.0]octane (bicyclic oxazolidine derivative) substituted with 3-(4-isobutyl-2-methylphenyl)propyl represented by formula (I) ##STR00001##
is disclosed.

A computer-based method for determining a sunscreen composition comprising a plurality of UV filter substances, comprises the steps of selecting at least one constraint for at least one characteristic of the composition to be determined (step 30), the at least one constraint comprising a sunscreen performance target; selecting an optimization objective from a plurality of optimization objectives (step 50); and automatically determining the sunscreen composition as a composition of filter substances from a set of filter substances (step 100), the composition meeting the at least one constraint and being optimized with respect to the selected optimization objective. The automatic determination comprises the steps of generating a plurality of candidate compositions, determining a sunscreen performance of the candidate compositions using a performance simulation tool and comparing the determined sunscreen performance of the candidate compositions with the sunscreen performance target. The method allows for an automatic determination of an optimum sunscreen composition based on constraints and objectives, thus avoiding manual trial and error methods that are lengthy and do not always lead to the optimal result.
