Liquid cleaning and/or cleansing composition comprising a polyhydroxy-alkanoate biodegradable abrasive

A liquid cleaning and/or cleansing composition comprising:

• a) from about 0.1% to about 20% by weight of the composition of biodegradable abrasive cleaning particles comprising polyhydroxy-alkanoates, wherein said biodegradable abrasive cleaning particles have a mean circularity from about 0.1 to about 0.6 according to ISO 9726 and mean solidity from about 0.4 to about 0.9 according to ISO 9726, and wherein said biodegradable abrasive cleaning particles have a biodegradable rate above about 50% according to OECD 301B;
• b) from about 0.1% to about 5% by weight of the composition of a suspending aid selected from the group consisting of polycarboxylate polymer thickeners, hydroxyl-containing fatty acid, fatty ester, fatty soap, carboxymethylcellulose, ethyl cellulose, hydroxyethyl cellulose, hydroxypropyl cellulose, hydroxymethyl cellulose, succinoglycan, xanthan gum, gellan gum, guar gum, locust bean gum, tragacanth gum, succinoglucan gum, or derivatives thereof, or mixtures thereof;
• c) from about 0.01% to about 20% by weight of the composition of a surfactant;
• and
• d) from about 65% to about 99.5% by weight of the composition of water.
