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.

The present invention relates to a method for producing collagen peptide preparations comprising recombinant collagen peptides, to collagen peptide preparations produced by means of said methods, to products containing the collagen peptide preparations and to uses of the aforementioned preparations and products.

Provided is a composition including: an acrylamide compound (A1) having a molecular weight of 150 or greater but 250 or less; and a multifunctional polymerizable compound (A2), wherein a content of the multifunctional polymerizable compound (A2) is 15% by mass or greater but 35% by mass or less.

Compositions comprising one or more chelating agents and optionally zinc ion salts are used to inhibit the growth or biofilm formation in bacteria associated with personal care products such as ophthalmic, pedicure, manicure or podiatric solutions. The compositions of the present application can also comprise gelling agents, antimicrobials, antibiotic or a pH adjuster. The compositions may be in the form of a solution, a gel, a cream, a jelly, a powder, a paste, a lotion, soap and a cleaner.

A method for treating or preventing one of a fungal infection of a nail and a condition of a skin surface excluding an oral cavity. The method includes the step of applying a composition to one of a nail surface adjacent to the infection of the nail and the skin surface having the condition. The composition comprises a plant-based bioactive and between about 0.2% to about 3.0% by weight of a metal chlorite salt. The composition does not contain a therapeutically effective amount of chlorine dioxide.
