A composition for topical application is provided which contains at least one water-sensitive active agent with a topical action and at least one polyol, the latter being present in a quantity which is effective for obtaining a water activity value of the composition of less than or equal to 0.85 with the aim of stabilizing the water-sensitive active agent, the composition containing at least one structuring agent chosen from polymers and oils. The water-sensitive active agent can, in particular, be an enzyme. The composition obtained can be used for cleansing and/or caring for and/or protecting the skin and/or keratinous fibers.
A composition comprising water, at least one water-sensitive active agent with a topical action and at least one polyol, said composition containing no calcium salt, said polyol being present in a quantity which is effective for obtaining a water activity value of said composition of less than or equal to 0.85, said quantity being at least 30% based on the weight of the total composition, and said composition comprising at least one structuring agent selected from the group consisting of acrylic polymers, methacrylic polymers and oils.
A composition comprising water, at least one water-sensitive active agent with a topical action and at least one polyol, wherein said polyol is present in a quantity ranging from 30 to 99.99% by weight, relative to the total weight of said composition, and said composition comprises at least one structuring agent selected from the group consisting of acrylic polymers, methacrylic polymers and oils.
