Christmas crackers will be sold to 12-year-olds rather than 16-year-olds at present under moves to abolish "pointless" regulations.
Other changes include the removal of "unnecessary" regulations covering shipbuilding repairs or specifying the quantities of heavy metals in pencils, simplifying the way firms use assets to raise finance, and reducing administration on low-risk electrical works.
Around 300 regulations have now been changed or axed from a total of 1,500 identified for reform through the Government's Red Tape Challenge.
This is the latest round in a series of announcements, which the Government said were in response to issues raised by businesses.
Business minister Michael Fallon said: "Setting business free from the restrictions that hold back enterprise is a compulsory step on the road to growth. We've listened to firms and taken prompt action where regulation presents barriers - but there is a huge amount still to do.
"As well as cutting the overall burden of regulation, we are sharpening up how rules are enforced."
Dr Adam Marshall, director of policy at the British Chambers of Commerce, said: "We welcome the Government's ongoing efforts to deregulate and to limit unnecessary red tape.
"Although the volume of new regulation has decreased, the number of changes emanating from both Brussels and Westminster is still too high. Constant changes to regulation are a distraction for firms at a critical time for the UK economy - when companies should be focusing on things like breaking into new markets, building their workforce and generating wealth."
